Excavator Learning Content

The following is a summary of the main contents of the excavator.

The learning of the excavator consists of four modules.

1. The basic structure and working principle of the excavator. This section aims to familiarize trainees with the performance and function of the overall structure of the excavator and to master the standard operating methods of each unit. Mainly learn the name and function principle of power equipment, work equipment, walking mechanism, operating system control, hydraulic system, electrical and electronic control.

2. The excavator safety operation procedures and precautions, the purpose of learning this module is to enable the trainees to master the safe operation of the excavator during the construction process to avoid accidents. The main content of the study is the daily inspection of the excavator, on-site construction analysis, operational safety instructions, driving, parking and parking safety instructions.

3. The various operating skills of the excavator are trained. This module is the focus of the actual operation, and the use time is relatively long. Through the learning of this module, the students can master the various working conditions and operation methods of the excavator. Independent construction capability in terms of operational skills. About the operation. The main learning activities of the module include: excavation, shovel, trenching, backfilling, leveling, gully, overgroove, up and down slope, slope repair, loading, one-way steering, local steering and support, excavation foundation, slotting , set up swamps, trap self-help, monorail drive, FW, etc. ARD and reverse manual operation, as well as transporting carts up and down. Through repeated practice and skill, the trainee can easily control the excavator.

4. The maintenance of the excavator. Through the study of this module, the trainees can master the routine maintenance and repair methods of the excavator as well as the diagnosis and elimination of common faults. The main basic principles of this module are: prevention and mandatory maintenance. Learn the classification of excavator maintenance: regular maintenance, maintenance cycle, seasonal maintenance. Learn daily maintenance: check fuel, oil, hydraulic oil, gear oil, cooling water. Learn to check the grease: Apply grease to the boom, arm, bucket and hinge pins of each cylinder. Learn how to replace the consumables of the excavator. Learn how to diagnose and troubleshoot common problems and techniques.

The World's Smallest Excavator, Small Size, Can Work

The world's smallest excavator weighs only 300 kilograms. The smallest excavator naturally has its own use. The world's smallest excavator is PC01 produced by Komatsu, Japan, because Japan is an island country, in many places, the streets are narrow. In order to meet the needs of construction work in a small area, Komatsu has produced this miniature excavator to deal with various narrow and inaccessible environments. Komatsu excavators are only 55 cm wide, which means people can enter as long as they can enter. It has the following advantages:

1. small size

The small size means that Komatsu can work in some very small areas, which is equivalent to one person's height, while other excavators cannot. For example, in a villa's back garden, greenhouse, orchard, and buildings in these places, if a large excavator comes in, it will cause a lot of damage.

2. light weight

Light weight and can be moved, which means you can steal it if you just find a van, no, it is going to be carried. So why do Japanese people develop such miniature excavators? This is the need of the market and life. It is said that the price of Komatsu is about 120,000 yuan, so the villa industry is mainly used to open its own backyard and garden. Komatsu PC1 is a good choice.

3. the price is close to the people

The price of Komatsu PC01 ranges from 50,000 yuan to 200,000 yuan, but a friend who likes it can also set up a second-hand. The price is between 30,000 and 50,000 yuan. It is very windy to take the Komatsu PC01. Komatsu PC01 can rotate 360 ​​degrees, the moving speed is not low, it will give you the feeling of braking.

The World's Largest Excavator, 96 Meters High And 215 Meters Long

Whether it is building a house in the countryside or building a high-rise building in the city, some mechanical equipment is common, such as cranes and excavators. These mechanical devices not only improve work efficiency, but also reduce physical labor, which is what children see. How big is the machine? Today is the largest excavator in the world. How big is it?

Its name is Bagel 288. This excavator is known as the "land carrier." This excavator was developed by Krupp. If you look closely, he is like a huge steel monster that makes you feel yourself. This excavator is extremely small, 96 meters high, 215 meters long and weighs 45,000 tons. It is as large as a standard football field, two and a half, wider than the aircraft carrier.

There are 18 buckets on the wheel of this excavator. Each bucket can easily accommodate eight adults. The runner has a diameter of 21.6 meters and is about 7 layers. Standing in front of it and saying that it is an "ant" is not excessive. This excavator still maintains the Guinness World Record. Of course, with such a large size, the cost and time to manufacture it is amazing.

It is understood that the cost of this excavator has reached 700 million yuan. It was developed in 1978 for a total of five years. However, its efficiency cannot be underestimated. This excavator can excavate 250,000 cubic meters of coal per day. This means that it can dig into Mount Fuji in Japan in one day, because Mount Fuji is too big, one can't control it, and it takes 5 people to fully control it.

Although its advantages are obvious, the disadvantage is that it is too large in size and slow to move. It takes one minute to walk 10 meters, not to mention its speed and energy consumption. This excavator is dry, absolutely A king. Generally speaking, the working place of this excavator is fixed because the cost of one-time handling is also very expensive.
