Please understand the entry of the excavator, how the excavator is driven?

Excavator's 200,215,225 and other numbers are mostly related to the weight of the machine, 200 is about 20 tons, 230 is about 23 tons, the same 360 is about 36 tons, although it is not very accurate, and the deviation is not too big, most of them are divided in this way in the line, some brands are special, Carter 320 and 200 basic gear, 336 and 360 basic gear, Kato 820 and 200 basic gear, Liebherr or Tecreth are all their own school, I personally think it is more intuitive to look at the bucket Rong, As a bit of a humble point, numbers such as 200 or 260 are also roughly the same as the flow rate per minute of the main pump.

Liugong loader is good in China, the excavator is worse, the same is a domestic product, Sany is better, and the joint venture brand is a little bigger, gentle use, maintenance in place, the working conditions are not too bad, or can be used.

In addition, I would like to remind you that in the engineering industry, you must have a stable and continuous way of life, and you must have a good account, and I wish you good luck!

Hello, I said you don't want to buy Liugong excavator, buy Sany is good, all say that Sany is not good, in fact, Sany is not good for small digging, but Sany digging is still very interesting, fuel consumption, power, speed are good. The money is not as expensive as the imported one. In addition, the European pure import Volvo digging is also good, it is currently the most fuel-efficient machine in the same model, Japanese Komatsu, imported Hitachi these two mouths are OK, but the domestic Hitachi is not good, old oil leakage.

The saying of friends in the industry is called: broken arm Kobelco, fried Hitachi. Hehe, but it is more expensive than Sany's, and Sany's is OK, especially big digging, after all, is it cheaper, and you can repay it quickly if you installment.

Also, most of the models in front of the excavator are talking about tonnage, that is, 200 is about 20 tons. But some brands are different. Like the Carter 306, it is 6 tons and above, and those who don't understand it think it's a ton.

In this business, pay attention to the maintenance of the car. Hehe, I'm the car boss, and I'm a small digger. Hehe, hope.

I know that Liugong's loader is the best in China If you want to buy an excavator, or the quality of Japanese products, I don't have to say that the domestic machine is not yet able to meet that standard in the real sense How much money do you plan to buy It is brand new or 2 hands I recommend one to you.

There are quite a few people who buy Kobelco now. It's fuel-efficient.

1. The engine start switch is the position where the key is inserted to start the excavator: it means to start and start; ON means to turn on and open, when the key is turned here, the whole circuit of the excavator is turned on; OFF means to disconnect and close, when the key is turned here, the whole circuit of the excavator is disconnected, and the key can be plugged and unplugged; heat means to warm up, and when the temperature is low, the key is transferred here to warm up.

2. The dashboard can feedback the status information of the excavator at all times, such as fuel oil volume, cooling water temperature, oil temperature, engine speed, working mode, time, equipment maintenance information, fault inquiry, etc. Of course, the dashboard and display content of each brand model are different, including LCD screens and digital displays.

3. The working mode can generally be selected in the excavator operation: S standard mode, H heavy digging mode, L refurbishment mode and F micro repair mode. There are also some more advanced ones, such as P H strong working mode, M S standard mode, E economy mode and so on.

1. Loading:

1. The body should be in a horizontal and stable position, otherwise it is difficult to accurately control the rotary unloading, thereby prolonging the operation cycle time;

2. Keep an appropriate distance between the body and the truck to prevent the tail of the body from colliding with the truck when doing a 180-degree turn;

3. Try to carry out left-turn loading, so that the field of vision is wide, the operation efficiency is high, and the rotation angle should be correctly mastered to reduce the time used for rotation.

2. Excavation: 1. For example, when the bucket cylinder and the connecting rod, the stick cylinder and the stick are 90 degrees to each other, the excavation force is the largest;

2. When the bucket teeth and the ground are kept at an angle of 30 degrees, the best excavation force is the lowest soil cutting resistance;

3. When digging with a stick, the angle of the stick should be guaranteed to be between 45 degrees in the front and 30 degrees in the back. The use of both boom and bucket increases digging efficiency.

The excavator mainly excavates soil, coal, sediment, and pre-loosened soil and rock at the Zaoyu construction site, and loads it into a transport vehicle or unloads it into an earthmoving machine in the stockpile.

Classification of excavators:

There are two types of common excavators: internal combustion engine-driven excavators and electric-driven excavators. Among them, electric excavators are mainly used in plateau anoxic and underground mines and some other flammable and explosive places.

1. According to the different sizes, excavators can be divided into large excavators, medium excavators and small excavators;

2. According to the different ways of walking, excavators can be divided into crawler excavators and wheeled excavators;

3. According to the different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines;

4. According to the use, excavators can be divided into different categories such as general excavators, mining excavators, marine excavators, special excavators, etc.;

5. According to the bucket, the excavator can be divided into the front shovel excavator, the backhoe excavator, the dragline excavator and the grab shovel excavator. Positive shovel excavators are mostly used to excavate materials above the surface, and backhoe excavators are mostly used to excavate materials below the surface.

Opening an excavator involves a lot of technical actions, and the excavator is also one of the most functional parts of all construction machinery, so an excellent excavator driver must master a variety of operating skills, loading, digging trenches, brushing slopes, throwing soil, picking up leveling, trimming, etc.

Although the excavator is a technical job, but if the emotional intelligence is too low, not good at communicating, it is difficult to gain a foothold in the industry, a mature excavator driver must have the ability to expand contacts, because in the excavator industry, personnel changes are relatively large, today with the engineering team to work, tomorrow may go to work with another boss, so in the industry, technology is important, but communication is also essential.

Excavator driving is a technical work, so, if you do not operate for a long time, it is easy to cause technical regression, some drivers rely on their own good technology, work fast, often do a period of time to play for a few months, in this way, no matter how good the technology is difficult to progress, and even will be degraded, in the long run, will be surpassed by others or even replaced.

Although driving an excavator is a relatively free job, it does not mean that you can rest at any time, even if the level is high, you must practice from time to time, otherwise no matter how good the technology will be degraded, no matter how good the reputation will be gradually forgotten.

1. There are two types of excavators: internal combustion engine-driven excavators and electric-driven excavators. Among them, electric excavators are mainly used in plateau anoxic and underground mines and some flammable and explosive places in their early tomb sheds. Ordinary ground projects do not need to use electric power to drive Wang Xu, because he is affected by power reserves, and the work continuity is not strong and inconvenient;

2. According to the different ways of walking, excavators can be divided into crawler excavators and wheeled excavators; Wheeled excavators are not very common and are more used in road construction. If it is deep excavation, reclamation, etc., crawler excavators will be used, and there will be no inconvenience in walking;

3. According to the bucket, the excavator can be divided into the front shovel excavator and the backhoe excavator. The front shovel excavator is mostly used to excavate materials above the surface, and the backhoe excavator is mostly used to excavate materials below the surface. This is also based on the need to dig deep or shallow.
