Excavator Leveling Tips

For beginners in excavator, leveling is not an easy task. Let's take a look at the techniques of leveling.

1. Mark as reference point

If you stand on the ground and can see something on the same level, you can make a mark and use them as a reference point.

2. Remember to find peace of mind

When the excavator is leveled, you can't be greedy. You should pay attention to it. Old drivers are usually far from reaching levels because it is difficult to coordinate when you reach your arm; so keep your arms vertical as you are level. This line oscillates back and forth, extending forward through one or two vertical lines, far enough to form a vertical line.

3. First find a flat excavator

The excavator itself must be flat. If you are not flat, it is difficult to level it. After finding the bucket, place the bucket on the water and turn it over. Do not move the boom. If the excavator is flat, the left and right pendulums are flat.

4. Look for time to see if there is an error

The error must be adjusted in time. Generally, on an excavator, it is not high or low. This is a phenomenon that everyone will have. So after you have found one or two paragraphs, take a look at it. When you find an error, check the error. Then adjust, some people's vision error self-adjustment habits are very good, some people can't do it, so you have to look down.

5. Rational use of surrounding reference materials

It is also more useful to learn to use surrounding reference objects as a standard. There is no need to refer to the standard point. It is not too wide and can't find the level. It depends on the terrain to determine the height from low to low. In fact, the leveling measurement is also something I have to take a look at, think about it, plan it, and do it again.

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.

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.

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 Cleaning Mud Skills Sharing

The position of the release device is very important. From the above, the hand must be slow, and the heart can't eat hot tofu. It is best not to use wheeled excavators in silt environments because wheel excavators can easily get stuck in the mud, unlike crawler excavators. It is more flexible and slippery in some ways. When the road is walking, it is easy to slip and unnecessary property loss occurs.

In this case, the best construction machinery partner is a track widening excavator, which is marked "LC" on cars and loaders. Because even if the crawler excavator is now in the mud, use an excavator to pull the mud around the excavator to the side, and then pull it out with a larger horsepower loader. This is also an important point.

In the case of deep mud, we usually use steel excavators, small excavators with around 1-2 steel plates and 200 excavators with 3-4 steel plates. However, when using an excavator to pick up steel plates, this is not a problem for drivers with rich driving experience, but for excavator apprentices and novices, this is really difficult, but as long as everyone has mastered the steel plate, The skill is that the steel plate can be easily picked up in this work.

The preparatory movement of the steel plate is the same as the preparation operation when the excavator performs the leveling operation. First, find the right place for the excavator and move on to the next step.

Next, gently turn the blade of the bucket to the outside, and then slowly extend the shovel under the steel plate to reach about 1/3 of the steel plate.

In the third step, slowly move the bucket to the inside, then lift the starter arm up and then extend the arm outwards, as this will prevent the steel plate from being lifted and hit the excavator once. Cab.

The technique for selecting steel plates is as described above. There is also the fact that the excavator driver's friend is required to pay attention to the fact that when the steel plate is placed, it is impossible to turn the excavator to a certain position and rotate the bucket. The steel plate is heavy. If it is as easy as tamping soil, it is easy to roll the excavator due to the weight of the steel plate.

When we put the steel plate in, we can extend the arm slightly to the side of the cab. If the distance of the arm is too far, the machine will roll the object.

Measures To Prevent Excavators From Falling Into The Mud

When it comes to excavators, there are many opportunities in the South and fewer opportunities in the North. Places that are often trapped are usually places with more water. There are groundwater, rainwater, lakeside, fish ponds, digging foundations, and unloading. In the yard, eradicating the excavator is both cumbersome and laborious. It may also be accompanied by tracks, so how to avoid and get rid of it. Let's discuss it below.

To the above, where the soil may be soft, you must first test it, push it down with a bucket, try not to enter more than four-fifths of the bucket, and the chain of your own excavator. To have a full understanding, you must always leave yourself behind the road. It is not good to ask other drivers at the construction site to improve their feelings. Peers will help each other.

In order to get rid of the fault, the excavator should always be kept as flat as possible and adjusted in time. Excavators are difficult to move in the mud. Basically, it is necessary to use the power of the bucket to move forward. Remember, the excavator cannot be supported too high. The deeper the support, the deeper the support. Sometimes it can be removed. The excavator was stuck because the bracket was too high. Other excavators cannot be pulled out. The turntable is stuck and the ground is inside. It is also mud, try to adjust to a straight line, steel plate is the best, you can also use cement blocks, large, rescue methods are generally in the middle and sides of the excavator mud.

Excavator Driver Needs To Know The Excavator Trenching Skills

Trenching is one of the skills that an excavator operator must master. It is not easy to master this skill. In the process of digging trenches, many operators will have problems with different grooves and different depths. So what are the operational skills of trenching?

1. Progressively digging trenches

When starting to dig trenches, start from the surface layer and dig one layer at a time. Don't try to dig it all at once, especially when the trench to be dug is deep. In addition, when digging a trench larger than the width of the bucket, it is necessary to dig both sides and then dig the middle.

2. The route for trenching must be straight

The most important thing about trenching is to follow the principle of straightening. Generally, it will be drawn with lime lines before excavation. The center line of the excavator and the middle of the bucket are aligned with the lime line.

3. Control of the bottom of the ditch

The control of the bottom of the ditch is crucial. At this time, you need to use the techniques of square and leveling. If the trenching is to install a water pipe drain, a certain slope is required at the bottom; if it is a foundation pit, the bottom level is required.

4. Maintain the flatness of the slope on both sides of the ditch

Many novice digging trenches are not well boring, mainly because the principle of tidying is not done, and the detailed operation needs to be further improved. From the beginning of the V-shaped ditch to the end, the slope should maintain the same slope. Of course, the soil and the depth of the ditch are different, and the slope needs to be adjusted accordingly. In addition, the operator must pay attention to the loose soil around the ditch to prevent the soil from falling, and should be cleaned with a bucket in time.

Here are three ways to dig trenches:

1. Shunbian: It refers to a narrow area of ​​the site. Like a clear channel, the bucket only digs along the side track line.

2. Alignment type: Mainly for the excavation of the road culvert trench, it means that the excavator and the ditch side are parked at 90 degrees.

3. Riding and digging: mainly the open area of ​​the site, the excavator is parked in the middle of the trench to be excavated, and the bucket is dug in the middle of the two crawlers.

Things To Be Aware of When The Excavator Goes Up And Down

Excavating uphill and downhill is a dangerous and difficult operation for many excavator masters. In order to reduce the occurrence of accidents when excavating the excavator, it is necessary to master some operational skills. Let's share with you some notes about the excavator's ups and downs for your reference!

1. Carefully observe the surrounding situation

First, the excavator must carefully observe the ramp before going up and down. It has a preliminary judgment on the angle of the ramp and the texture of the ramp, and determines whether the climbing is within the controllable range of the excavator operation. In addition, the road surface is too slippery to fit downhill.

2. Remove stones before going up and down the slope

Whether it is uphill or downhill, you must first remove the obstacles around you, especially to remove larger stones. When climbing, not a large stone will make the excavator track slip, and an accident will occur. it is too late.

3. Remember to fasten your seat belt

Most excavator masters do not have the habit of wearing seat belts, but when downhill, if there is no seat belt, the handle is easy to dump forward. So be sure to fasten your seat belt downhill.

4. Up and down slopes should be facing the slope

The excavator climbs the slope directly to the slope, and it is best not to turn on the slope, which is easy to cause rollover or landslide. Whether it is uphill or downhill, remember that the cab must face in the forward direction.

5. Don't forget to put down the bucket up and down the slope

When the excavator goes up and down, there is one more point to pay special attention to, that is, put the bucket of the excavator down and keep it about 20~30cm away from the ground, so that when there is a dangerous situation, the bucket can be put down immediately to keep the excavator Stabilize and let it stop sliding down.

6. Try not to park on the ramp

The excavator is best parked on a flat surface. When it is necessary to park on the ramp, gently insert the bucket into the ground, open the digging arm (about 120 degrees), and place the stopper under the track.

Excavator Walking Matters Need Attention to Avoid Rollover

During the operation of the excavator, the situation of the excavator rollover occurs due to the driver's operation or environmental conditions. Therefore, for your reference, we summarize some of the problems that the excavator needs to pay attention to during walking.

1. When reversing the excavator, it is necessary to predict the parking space in advance. It is best to ask someone to direct behind.

2. The excavator should walk straight on the ramp as far as possible while the bucket is at a certain distance from the ground. If there is a slipping, roll, etc., lower the bucket immediately. If there is a stall stop on the ramp, place the bucket on the ground immediately, place the lever in the neutral position, and restart the engine.

3. Before the excavator walks, check the road surface, clear the obstacles on the road, let the unrelated personnel stay away from the excavator, and then raise the bucket to start the excavator.

4. When the excavator is walking, try to choose a flat road surface to avoid the rotation of the upper turntable. When walking on a bad ground, avoid the hard object from hitting the travel motor and the crawler frame.

5. Check the direction of the track frame before starting to determine the position of the drive wheel.

6. Try to avoid the excavator walking in the water. If it is necessary to launch the water, be sure to check the depth of the water and the hardness of the bottom of the water in advance. If the underwater mud is too deep, or the water surface exceeds the track, it is not suitable to walk.

7. The driver should control the walking speed according to the road condition. When walking on the open flat ground, you can select “1”, and you can select “0”when going up and down.
