Things You Need To Know To Run A Small Excavator

Operating a good excavator is not an easy task. There are many places in the business process that need attention. I will tell you some tips on how to operate a small excavator.

1. Excavator procurement

Operating the excavator is actually started from the stage of choosing to buy an excavator, which is a tool for making money in the future. There are many considerations for purchasing small excavators, such as the market reputation of brand excavators, fault conditions, approximate operating costs, basic fuel consumption, maintenance and repair cycles. If you are not sure, you can find a friend who is familiar with small digging. There is one more thing to consider when buying an excavator. Choose imported small digging or domestic small digging.

2. Excavator operator selection

If you are the owner of an excavator, it is especially important to choose which machine, which directly affects the service life and reputation of your excavator. Pay attention to the operator's choice, don't leave a few hundred people, choose an apprentice who just started or didn't care about the excavator. If the performance of a small excavator is not good, it will affect the future business.

3. Engineering selection skills

For small excavators, the cost of the contracted project needs to be estimated before it is completed. It is necessary to know what to do and make money. Contracting earth and stone works is not easy. Things under the earth are simply unpredictable. Others ask you to dig a foot and it may take a whole day to throw it out. This is a time-consuming and laborious task. Small excavators generally have shorter construction periods. Before each construction, you must first see what it is. Two hours a day is not worth it. If you work in the mountains, you must equip the hammer. The work of excavating foundations is often inseparable from cannons.

4. Excavator safety

Micro-excavation and small-digging are mainly used in rural, municipal, and water conservancy projects. The site needs to be transferred frequently and is inseparable from the trailer. The trailer selected first should not be too high, too high, and it is not easy to wipe the wire. Secondly, it is recommended to stop the air brake. There are also small digging pits that often go up the mountain, and the wheelbase of the trailer cannot be too long, otherwise the curve is difficult.

5. Small excavation maintenance

Maintenance is a step that cannot be ignored in the operation of excavators. Maintenance or infrequently affect the service life of the excavator. The entire car was filled with butter, the bottom of the tank was emptied, the oil was inspected, the water separator was drained, and the coolant was checked. The maintenance cycle of the excavator must be completed on time to ensure that the excavator is used for a longer period of time.

Easy Replacement Of Excavator Air Filter In Just Six Steps

Excavator air filter(excavator parts drawing system)is one of the important products of the engine. It protects the engine, filters hard dust in the air, provides clean air to the engine, prevents the engine from being worn by dust, and is reliable and durable for the engine. Sex plays a key role.

To avoid this, the filter must be installed as required to enhance routine maintenance practices. The excavator reaches the specified maintenance time. There are a lot of excavator spare parts drawing on www.partsdic.com. The general filter is replaced for 500 hours and the fine filter is replaced for 1000 hours. Below I will tell you the steps to replace the air filter.

Step 1: When the engine is not starting, open the rear door and filter end cover of the cab, remove and clean the rubber vacuum valve at the lower cover of the air cleaner case, check if the sealing edge is worn and replace if necessary. (Please note that it is forbidden to remove the air filter while the engine is running, or wear a protective eye shield if you use compressed air to clean the filter).

Step 2: Remove the air filter element and check if the filter element is damaged. If yes, please replace it in time. Clean the external air filter from inside to outside with high pressure air. Note that the air pressure should not exceed 205 kPa (30 psi). Illuminate the inside of the external filter with a light. If there is a small hole or thin residue on the filter element after cleaning, replace the filter.

Step 3: Remove and replace the air filter. Note that the internal filter is a disposable part. Do not clean or reuse.

Step 4: Clean the inside of the box with a rag. Note that high pressure air purge is prohibited here.

Step 5: Install the inside and outside of the filter element and the filter end cap correctly, and make sure the arrow mark on the cover is facing up.

Step 6: After the outer filter is cleaned 6 times or the working time reaches 2000 hours, the outer filter needs to be replaced. When working in harsh environments, the air filter maintenance cycle should be shortened appropriately. If necessary, an oil bath prefilter should be used to replace the oil in the prefilter every 250 hours.

How To Identify Various Oils Of Excavators

The quality of the oil directly affects the service life of the excavator. The cause of many failures in excavators is often due to the use of inferior oil. Although non-pure oils sometimes do not cause damage to equipment in a short period of time, they pose a significant potential hazard and the failure is too late.

Some of them are for cheap prices, they know they are buying non-pure oil. Some people spend their money on real oil, but they are tricked into buying fake oil. There are many kinds of oils for construction machinery. How to distinguish various oils? Here's a simple way for everyone to share.

1. Oil identification

First of all, how to identify the quality of oil, share four methods for everyone:

(1) Inferior motor oil has special oil color and oil taste, such as dark brown to blue-yellow, and has an acidic pungent smell. The real oil color is brighter.

(2) Observe the bubbles. After the oscillation, the bubble size gradually disappears, and the oil is yellow after being "suspended".

(3) The feeling of inferior engine oil is special. After the water is shaken, there is slight emulsification and stickiness, and the short steel wire can be pulled out. Counterfeit oils usually have turbidity.

(4) Appearance packaging observation, if the appearance of the oil is found to be illegible, the material is rough, it is likely to be fake oil. You must also pay attention to whether there is a security label.

2. Hydraulic oil mark

(1) Identification of hydraulic oil content of engineering machinery hydraulic oil. By visual inspection, if the oil was found to be milky white and turbid, it was proved that the hydraulic oil contained more water.

(2) Using the combustion method. Light it with a clean cotton gauze and a little oil. If the sound is "beep" or flashing, the oil contains a lot of water.

(3) In the high temperature test method, the measured oil is placed in a dry test tube, and then the test tube is heated to above 100 ° C. If the test tube emits a sound, the oil may be foamed or turbid, or bubbles may condense on the tube wall. Indicates that the oil contains more water.

3. Transmission oil identification

(1) Color identification, the real oil is generally red.

(2) When the real oil "hangs the bottle", it is not clean for a long time.

(3) When the real oil is shaken, bubbles rarely appear.

(4) Crude oil is not easy to remove and can be extracted.

3. Gear oil identification

(1) Careful observation of color, the real gear oil is generally black to black green.

(2) When the smell of oil is smelled, the real gear oil will have a burning smell.

(3) Observe the fluidity of the oil. After the real gear oil is "suspended", it is not clean for a long time.

(4) Observe the oil bubbles. After the real oil is shaken, bubbles rarely appear.

(5) Observe the viscosity of the oil. The real gear oil is not easy to remove after touching the hand and can be extracted.

4. Identification of diesel

The original diesel oil is yellow, the flash point is above 60 °C, the inferior diesel has a large residual carbon content, the color is black, and the flash point is only 43 °C. At present, the agricultural fuel supplied in China is No. 0 diesel and No. 1 is No. 20 diesel. The identification methods of the two diesel engines are as follows:

(1) Cooling test method: A small amount of diesel glass tube was placed in ice water. If it solidifies immediately, it is not O-type diesel. If it does not cure, it is O-type diesel. If there is no ice water, you can use cold water instead.

(2) Combustion discrimination method: Two kinds of diesel oil are used for combustion comparison. No. 20 diesel is black smoke, and No. 0 diesel is black smoke.

(3) Oil quality observation method: No. 0 diesel oil contains less wax, low density and yellow color. No. 20 diesel contains more wax, higher density and deeper color.

(4) Density test method: No. 0 diesel is lighter than No. 20 diesel. The two diesels are mixed in a transparent container. It can be seen that the No. -20 diesel sinks and the No. 0 diesel floats.

Who Is Responsible For The Injury Of The Excavator Operator

Excavators usually work in special environments, such as construction sites. Excavators are not an easy task. During the construction process, accidents sometimes occur, causing certain damage to the personal safety of the workers. What should I do if the hired person is injured?

1. Who is responsible for being employed by a private boss?

In fact, many excavator operators are employed by private individuals and are also employed by private bosses. What if the injured person is injured? According to Article 11 of the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trial of Personal Injury Compensation Cases, if an employer engages in labor activities causing personal injury, it shall be liable for compensation. Therefore, the responsibility of the operator for personal injury is borne by the employer.

2. Who is responsible for being employed by the company's employer?

There are also some excavator operators in the form of employers and other employers. The excavator operator will establish a labor relationship with the company. The unit should be social insurance, including work injury insurance on the machine. When the excavator is injured, the social security fund shall pay compensation for work-related injuries. If the employer does not purchase industrial injury insurance for the operator, it shall bear the responsibility within the scope of the work injury insurance liability.

3. Third party intentional injury

If the third party’s infringement or intentional injury causes personal injury to the operator, the responsible party of the third party shall bear the corresponding liability for compensation. The third party’s infringement is caused by the excavation of the operator. The employer shall bear joint and several liability. The employer who has not purchased the work injury insurance shall bear the responsibility for compensation for work injury.

4. It is best for the operator to obtain an operating permit.

From the point of view of the excavator operator, in fact, many operators did not get the excavator operation qualification certificate. The insurance company has the right to refuse compensation for accidents caused by excavator operators who have not obtained the work permit. Therefore, it is recommended that you obtain a nationally recognized work permit through an excavator training school, etc., so that the accident will not be passive and a manifestation of personal safety.

5. How should the employer be responsible for the machine?

Both the individual employer and the employer must bear certain responsibility for the personal safety of the employed operator. It is best for an individual employer to purchase personal accident insurance for the operator. Employers should provide work injury insurance for the machine. This is both the responsibility of the driver and the responsibility of the operator.

Excavator Computer Board Failure Analysis

I believe that the friends who started the excavator have encountered the failure of the computer board. Today we will analyze the cause of the failure of the excavator computer board.

1. Excavator instrument or computer board water

If the internal water enters the computer board during charging, basically the copper foil of the internal circuit board will be completely burnt and oxidized and cannot be repaired; in addition, the plug wire harness of the computer board will enter the water, causing the pins of the computer board to oxidize, resulting in pins. Poor contact with solder joints on the board.

2. Throttle motor failure or abnormal operation

Motor overheating and short circuit can easily cause the computer panel throttle control circuit to burn out. Therefore, it is necessary to pay attention to keeping the throttling motor clean and clean, reducing the possibility of failure. In addition, when the excavator is energized, the throttle motor linkage is pulled. If you pull the throttle motor connecting rod hard, it may cause the computer board to burn out.

3. Poor contact of battery wire pile head, oxidation of contact surface

The electrical system on the excavator is the same as the household appliance. Poor contact of the fuse can easily cause the bulb to burn out. Poor contact between the battery stub and oxidation of the contact surface can greatly increase the possibility of damage to the computer board and the instrument, so it is also important to ensure that the battery head contacts.

4. Battery line reverse

This is not a small problem. If the battery cable is connected to the lamp, the fuse will burn out and the power circuit and CPU of the computer board will burn out. Some excavators have diodes on their pipes. If the power supplies are reversed, they are basically the same. The diode will also burn out.

5. Manual misoperation

When many people suspect that electronic components are not working properly, a short circuit method is used to test whether the line is normal. This method is very harmful and is not recommended.

Two Sand-induced Excavator Damage Caused Losses Of More Than 100,000 Yuan

On October 19th, the Shouguang City Public Security Bureau Jitai Police Station announced the latest cracked criminal case. Recently, Shouguang Jitai Police Station received reports from high villagers that sand was detected in the hydraulic system of the excavator. At present, the excavator has been damaged and the direct economic loss has reached 100,000 yuan.

Why does the front end of the excavator have sand? The police learned that the high excavator helped the villagers rebuild the greenhouse in the village, which is of great significance. The excavator was damaged, not only directly lost more than 100,000 yuan, but also caused indirect damage is incalculable, directly affecting the progress of the local post-disaster reconstruction work, the situation is extremely bad. The Shouguang City Public Security Bureau immediately set up a task force to mobilize the backbone of the Criminal Police Brigade, the Physical Evidence Center, and the Jitai Police Station to conduct a comprehensive investigation of the case. After an on-site investigation, the police extracted clear footprints and confirmed that they were committing a crime. At the same time, it was found that the hydraulic fuel tank cap of the excavator was intact, indicating that it was opened with a key. Except for the high, the person holding the other key is the most suspicious.

After asking about the high, I learned that a small village in Jitai Town has learned to open an excavator and cooperate with it. The last two have conflicts. Xiaojun always has the key to the excavator. Because only the victim’s testimony was high and there was no other evidence, the police investigating the case were not in a hurry to arrest the small force. Instead, through various means of investigation, evidence of a small army crime was collected to confirm the identity of another suspect. After further investigation, the identity of another suspect surfaced. The name of the suspect is Da Zeng. Subsequently, the police immediately arrested the two men.

After the trial, the police learned that Xiaojun was studying foreigners with Gao, because Gao was a foreigner and his business was not good. The locals were also familiar with the small soldiers and helped Gao to do a lot of business. Later, the business was booming, and the two men split up because of the distribution of interests, and eventually parted ways. Later, Xiaojun bought the excavator himself and realized the growth of the same excavator. Because Xiaojun often takes care of bad business, the relationship between the two is getting closer. Because the high has been relatively low fees, this has caused dissatisfaction with the small army in the same industry, so the group has increased significantly, and the black wind is big. These two sands are poured into the hydraulic tank of the high excavator, causing high. The machine is directly damaged. After the crime, due to fear of being discovered by the public security organs, the shoes worn by Xiaojun during the crime and the key to open the tank cover of the excavator were thrown into the garbage dump, but the careful police officers found clues left in the crime. At present, two suspects have been criminally detained in accordance with the law.

Man Sentenced To Nine Months For Stealing Excavator Diesel In The Middle Of The Night

The man found the "business opportunity" of the parking lot, rented a car platform first, then modified the vehicle, stepped on the scene, and tried his best to punish the excavator for selling diesel. Recently, the Longhai City Procuratorate of Fujian Province filed a public prosecution, and Cao was sentenced by the court to nine months in prison.

Cao is a person who has just been released from prison, but he has not learned the lesson. He once again launched the idea of ​​theft. He saw the excavator parked at the repair shop, neglected in the middle of the night, and found the "business opportunity". In order to facilitate the "acting", Cao rented a van, rented 1,500 yuan a month, and then modified the deck. Put the plastic bucket and plastic tube in the car and equip it with a pump.

On the morning of April 10, 2018, Cao drove to a repair shop in a village in Jiaomei Town. The repair shop had been arranged in advance. When there is no one, the truck is driven to the side of the excavator and the tank of the excavator is opened. This pump is used to pump the diesel and distribute small plastic buckets. Subsequently, Cao drove to the village entrance and other places, and sold the stolen diesel to strangers in bulk at 150 yuan. As of the time of arrest, Cao had stolen 1050 liters of diesel fuel, with a total value of 6,815 yuan.

Excavator Loading Tips Sharing

Today, I will share several tips about excavator loading.

1. The loading skills of the ground

The first place to load is to pick a station that parallels the excavator and the dump truck. There is a certain distance between the excavator and the dump truck. The approximate standard is: when the excavator is traversing, the bucket can be located above the dump truck, and the angle between the boom and the arm is about 100 degrees. This allows for flexible arm movement and a safe distance between the excavator counterweight and the dump truck.

Then you can load the car, whether you are from the back or from the back to the front, you can use a shovel to control the rhythm. The bucket should be turned from the middle of the rear panel of the dump truck. When installing the first half, check the arm slightly so that the material falls in the middle of the large box. If it is sand, you should slowly open the bucket. Because the sand is loose, the bucket will begin to spread out without completely opening the sand.

2. High platform loading technology

High-loading is an excavator with a low point at the dump truck and is the easiest way to load a car. The method is labor-saving and efficient, and is a loading method widely used by drivers.

For high-load trucks, the most important thing is to trim the platform. The platform can't be too high. It is best to get close to the height of the dump truck. In this way, the excavator can not only see the situation during transportation, but also accurately put the soil into the correct transportation process. position. During operation, the excavator should adjust the position at any time to maintain the proper distance between the excavator and the dump truck.

The operation of high loading trucks is relatively simple. When loading, the track should be square and the body should stop. At the same time of loading, the platform should be cleaned up in time, and the direction of the loading platform should always be paid attention to avoid safety accidents.

3. Low load

In the low position, the dump truck is on the ground, and the excavator is in the low-lying area. Since the position of the excavator is low, the operator can't see the inside of the car and can only estimate it by feeling, so this is the most difficult to load.

Low-level loading generally occurs in the work of foundation excavation and dredging. The greater the difference between the working surface of the excavator and the ground, the greater the difficulty of loading. When loading, the size of the arms should be increased as much as possible to allow the material to slide down as evenly as possible. After the materials in the vehicle are stacked, the front and rear push buckets are basically flattened.

Rainy Day Excavator Maintenance Method

In this article, let's talk about several aspects of rainy day excavator repair for your reference.

1. Timely cleaning

In case of heavy rain, it should be cleaned up in time.

2. Paint surface

The acidic components in the rainwater have a strong corrosive effect on the surface of the excavator paint, which can damage the paint surface of the excavator over time. Therefore, in the rainy season, it is best to paint the excavator. The easiest way is to wax. In a long time, the sealing effect is better. Regardless of the method used, the excavator should be coated with an invisible protective layer to prevent fading and aging of the paint surface.

3. Chassis care

The chassis is closest to the ground, especially affected by road conditions. In general, this part is most prone to rust, and the wheel casing may even loosen the perforations. Therefore, it is necessary to pay attention to the cleaning and anti-rust treatment of the excavator chassis, and to do the anti-rust treatment of the chassis.

4. Ignition start

On rainy days, if you run into problems where the engine is not easy to start, sometimes it will be weak even if you barely start it. The most likely cause of this problem is that the ignition system is leaking due to moisture, thus losing the normal ignition function.

Once the ignition system performance is found to be poor, the ignition performance is poor and the engine performance is degraded. It is best to wipe the inside and outside of the distribution plate and wire with a dry paper towel or a dry cloth, and then spray the desiccant with a special desiccant spray can. At the switchboard cover, battery connector, line connector, high voltage line, etc., the engine can be started after a period of time.

Excavator Hoisting Tips

In this article, we will discuss several issues to be aware of when excavator hoisting.

1. Safely hoisting to prevent slipping

There is usually a hook behind the barrel. Hoisting here is the safest. Especially when the object needs to be lifted to a certain height, if the rope is hung on the tooth, it will fall easily during the hoisting process. The use of hooks ensures that the rope does not slip, which is the recommended safety boost.

When the object being lifted is close to the excavator, it is very suitable to lift the object directly with the teeth. In addition, the hook hook is very convenient and effective if the distance to be lifted is not very high.

2. The lower plate is stable, preventing rollover

Stabilizing the body is a precursor to efficient and safe work! During the hoisting process, the excavator must stand on the horizontal stop surface; if it is necessary to lift the object to the inclined surface, first dig a horizontal stop surface. The positioning of the excavator's chassis is also very important. The smaller the angle between the lifting direction and the direction of the chassis track, the safer the excavator. The greater the angle, the more likely the excavator will tip over.

When the excavator is hoisted, it is actually a lever state. Always pay attention to the distance between the weight of the lifting object and the center of gravity of the excavator.

The closer the lifting object is to the center of gravity of the excavator, the safer the excavator and the greater the lifting capacity. The farther the lifting object is from the center of gravity of the excavator, the greater the risk of the excavator tipping over, and the greater the lifting capacity of the excavator.

3. Reasonable operation, safety first

When the hoisting height is too high, care should be taken to raise the object and not raise it too high. Once the excavator is in danger of tipping over, lower the boom for the first time and quickly place the sling on the ground.

The last point is that when upgrading, you must make sure there are no people nearby. Before lifting, ensure that the hoisting rope is vertical to prevent collisions and casualties.

Excavator Novice Needs To Understand The Slope Operation Precautions

Sometimes excavator operators need to work on the ramp to improve efficiency. In fact, the operation on the slope is still very dangerous. Once the operation is not good, the excavator will dangerously lean back.

Next, I will simply share with you the experience I have summarized over the past few days so that everyone can avoid risks.

First of all, the direction of the excavator must be flat, you must pay attention! If the work on the slope is not on a flat surface, if the uneven ground is shaken twice on a flat surface, the uneven ground on the slope will cause the center of gravity of the machine to be unstable and dangerous.

The second point is to avoid too fast when lifting the boom, because if it is too fast, the center of gravity of the machine will be retreated, causing the center of gravity of the machine to turn backwards, posing a danger.

The third point, when the middle arm is excavated, the first thing is that you can't talk about the pile of soil in front of the machine. Also, don't spend too much time in the bauxite. This can cause some relatively large clods to roll off when they are too fast. Machine and people.

The fourth point, pay attention to the cooperation of the boom when closing the middle arm, mainly to prevent the machine from being jacked up when the boom is closed, which causes the center of gravity of the machine to be dangerous.Tonkee Company has ten years experience in excavator spare parts area.

The fifth point, when rotating, should not be too fast, too fast will lead to rapid changes in the center of gravity of the machine. Also, before each rotation, you should look around to prevent it from entering the machine.

The sixth point, when going backwards, avoid going straight back. If you can keep going, don't think you can go straight back. This idea is wrong. You should turn the machine over.

Excavator Indoor Construction Needs Attention

Pay attention to the following points when working indoors:

1. Height limit. When working in the height limit space, the boom should be able to play horizontally for easy operation. If the boom cannot be lifted, it is not recommended to enter the construction. Because the big hand can't lift, the arm can't move before and after. When you are in bauxite, pay special attention to lowering the height of the boom. If you don't pay attention, you will easily encounter the above obstacles. If the paint is lost, the top of the cylinder will be deformed. Sometimes it is often a construction accident caused by operating habits.

2. Limit width, when working in a limited space, the width of the on-site construction environment is larger than the diameter of one rotation of the excavator's rotating buttocks. If this condition is not met, care should be taken to control the gap between the big and small arms and the tail of the excavator when moving, to avoid unnecessary damage caused by collision. When the excavator passes through a limited environment, the road is leveled first, and the excavator is allowed to pass through the limited width section. The side shall not be high and the side shall not be low. It is easy to get on a taxi. In addition, when the obstacle is widened, the cab side armrest, the door lock and the shock absorber block are easily caught by the obstacle due to being extended outside the cab. Be careful to avoid it.

3. the limit is limited and high, should consider this environment comprehensively, combined with the above two points, observe the upper and lower, front and back, reduce the speed of movement, do not worry. Stable and win. If conditions permit, construction can be carried out at both ends to avoid many obstacles in the construction environment. Although there are often non-wet shoes on the river, I would rather be careful to let the ship have a million years of history. It is not good to win in stability.

Talking About The Experience of Using Broken Hammer

Hello everyone, today we will talk about the experience of using circuit breakers.

Hit the guide in the hammer for about 3 hours. When you encounter a hard rock or an angle with your taxi, tap it when you are hit.

If you break the mountain, first remove the loose stone and then hit the stone below. At the beginning, it will be difficult to play some, but when you are empty or vertical, the stones will all fall. ...if the stone below is empty, the stone above is slanted and long, you can't move for a long time, you can choose to play a row of holes, then the hammer, the stone will come down.

A breakthrough must first create a gap so that you can work well, or you can hit it in the east, hit it in the west, and hit it when you hit it. You can't find it. The important point of the break is to look at the direction of the stone, see how long the seam is, and fight along the seam. The most important thing is to listen to the sound. If it is broken, it is a big voice. It is very sharp. You don't have to think about it. Change the angle. This sound is hard to play, or it can't move. You need to change the angle first until you hear the heavy, heavy sound, which means it is fully realized, or you can break the gap and keep the sound. If you change your voice, this means you have to adjust the angle slightly.

If it is a big noise, I suggest you change one. If all the places are like this, it means that it is almost impossible to play, otherwise the battle will take a long time. When the pedal is pressed for about 30 seconds, it is almost lifted and then depressed. If you can't move, change the angle, or move the car to change direction.

What Should I Do When The Excavator Is Shaking

In this article, I will tell you how to do when the excavator is shaking?

There are two main reasons for machine rocking.

First of all, the ground is not flat. Second, the coordination of the operating machine is not good.

Below I will share the treatment of this problem: 1. The machine does not stop. Novice friends may not pay attention or feel the machine. Is it stable? In fact, when there is a little stability, the machine will shake slightly. It is mainly reflected on uneven ground, the flat bottom is not visible on the hard bottom, and on the concrete floor, you may think that the ground is flat. The operation does not sway. In fact, at the same level, concrete floors are more prone to sway than soil. The specific reason is that the cement road surface is too hard and has no buffer. Solution: Trim the machine and level the floor. Usually, which side of the soil is grounded. After the block is completed, lift the arm and let it down easily. If you think the machine doesn't look unstable, it will prove that it is flat. If there is a corner, it will have a little dirt.

The problem of motion coordination is the most critical reason. Motion coordination is the basis of all operations and the most important reason for machine swing. The specific manifestation of non-coordination is that the role is incoherent and the coherence is decomposed. For example, when a person is on Earth, an action action is performed. Solution: The way to improve coordination of movement is to improve coherence. This is simple, but it is difficult and difficult for novice friends. Before practicing coherence, you must clearly know which pole corresponds to which action, subconscious. Know which pole and which pole you want to play. On this basis, the consistency of the exercise is much simpler. The specific operation is to perform multiple actions simultaneously during the operation, which is also called a composite action. For example, in the bauxite mining process, the intermediate arm is first used with the boom bucket. After the soil is full, lift the boom and rotate. When the position of the bauxite point is about to open, open the stick to open the bucket. When the dirt in the bucket is about to be completed, it will rotate backwards. In the process, you first need to know where the next bucket is, then adjust the arms, buckets and boom before reaching that position. These operations are done during the revolving process and you can dig directly after the digging point. Connect all actions and let the machine stop. This is coordination. The more actions, the more stable the machine!

Excavator Troubleshooting Methods That Novices Need To Know

In this article, let's discuss the faults and solutions that often occur in excavators for beginners' reference.

First of all, the sound of the cab is not normal. Check if the silicone oil damper at the four corners of the cab is loose. When the damper screw is loose, the cab will generate abnormal noise, especially when the engine is running at high speed, the cab and the surrounding area will emit abnormal noise. The glass is particularly noticeable, so we need to tighten the four screws under the cab.

The cab has a slight vibration when there is a click in the rotating part. This vibration is caused by impurities between the gear and the gear or after the gear is broken. When rotating to a fixed position, if there is abnormal noise, the rotary motor appears. When vibrating, check the gear oil and lubricate the butter with impurities or nails.

The hydraulic pump is abnormally vibrating. First, we need to check if the hydraulic oil is insufficient. Then, the professional hydraulic service technician checks whether the pressure is normal, whether the engine power is matched, whether the hydraulic pump output pipe is shaking, whether the regulator is issued, and the safety should be checked. Check if the solenoid valve switch is in place, check the hydraulic oil and return oil filter for metal powder, and judge whether the plunger is worn. Shake the pilot tubing and check that the pilot filter and filter fittings are clogged.

If the engine is vibrating, check the four foot pads of the engine for damage. If it is damaged, replace it with a new one. This will ensure the balance of the engine.
