What are the excavation skills of excavators

There are many skills, the most important point is that the excavator must be flat on the road, and when the excavator is rotating, there must be leeway, pay attention to safety. There are leveling skills, slope brushing skills, road repair skills, ditching skills, and some work experience skills, ways to do things, you are asking for skills, I will give you an outline, you can ask me privately for advice.

1. When the excavator goes uphill, the driving wheel should be behind and the arm rod should be on it; When the excavator is going downhill, the drive wheels should be in front and the boom should be behind. When going downhill, drive slowly and do not change speed on the way. 2. The excavator should not turn too quickly, if the curve is too large, it should be turned in stages.

3. When the excavator rotates, the rotary clutch should be used to cooperate with the brake of the rotary mechanism to rotate smoothly, and sharp rotation and emergency braking are prohibited.

4. It is strictly forbidden to repair, maintain, fasten and other work when the excavator is working. If there is abnormal noise, peculiar smell, excessive temperature rise and other conditions in the process of work, it should be stopped immediately for inspection.

5. Before the bucket leaves the ground, it is not allowed to rotate or walk.

6. When the crawler excavator moves, the boom should be placed in the forward direction of the walk, and the height of the bucket from the ground should not exceed 1 meter.

7. When maintaining, overhauling, lubricating and replacing the pulley at the top of the boom, the boom should be dropped to the ground.

8. When excavating, the soil should not be too deep, and the bucket should not be too violent, so as not to damage the machinery or cause an overturning accident. When the bucket falls, pay attention to the intolerance of the eggplant sun too fast, so as not to cause the unstable lower frame and the whole machine to shake back and forth.

The geology of the working face and the surrounding environment should be observed first, and there should be no obstacles within the rotation radius of the excavator.

After the excavator enters the construction site, the driver should first observe the geology of the working face and the surrounding environment, and there should be no obstacles within the rotation radius of the excavator, so as not to cause scratches or damage to the vehicle. After the machine is started, it is forbidden for any personnel to stand in the bucket, on the shovel arm and on the track to ensure safe production.

In the work of the excavator, it is forbidden for any personnel to stay or walk within the radius of rotation or under the bucket, and non-drivers are not allowed to enter the cab to touch and move, and they are not allowed to train the driver, so as not to cause damage to electrical equipment. When the excavator is shifted, the driver should first observe and honk, and then move to avoid safety accidents caused by someone on the side of the machine.

1. How to climb a flat truck with a small excavator (no ladder).

The flatbed truck without a ladder on the small excavator is very easy to be crooked, resulting in the more and more crooked when reversing in the back. In fact, this problem is easy to solve: adjust the angle of the excavator when getting on the car to ensure that the chain plate and the flat car are aligned; Then turn the excavator to the right (one side of the cab excavator chain plate is vertical), support it with the excavator arm, and the excavator slowly climbs up.

This process must be slow, while reversing while observing the adjustment, the faster the speed, the easier it is to deviate.

2. How to dig a T-shaped trench.

The so-called T-shaped ditch is to dig a trench to focus on the wall, and such a trench is more difficult to dig. It's best to dig from the end of the T-shaped contact with the wall, and don't panic when you encounter this kind of thing, because in addition to riding on the ditch to dig, everyone will dig wide.

If you encounter sand, it is not recommended to ride on the ditch to dig, which is easy to be dangerous. If the soil quality is better, you can ride the trench to dig, it should be noted that: do not collect the soil strongly with the small arm when digging, which will cause the excavator to deviate; Use a bucket to dig, trying to dig out the shape of the trench at once.

3. How to level the ground.

Regarding leveling, this is the most basic operating skill of the driver. Leveling is not a set of theories that you can master, it takes a lot of practice, when leveling the movement should be slow, how slow you can dig, how long you can dig, how long you can dig, and then slowly scrape through the soil with the tip of a shovel.

So how do you look at the uneven? If it feels high, scrape it slowly, and when it is low, push a little dirt with the tip of the bucket. In this way, step by step, you will always grasp a reasonable and flat perspective.

It should be noted that the excavator must be stopped and leveled, if you are working on the mound, you need to move the excavator left and right so that the bucket is parallel to the ground.

4. How to load the truck quickly.

I'm loading too slowly, how can I load it fast? Many friends have encountered this problem, here is a little trick.

The first is that the excavator should stop steadily, so that it is fast and stable when turning.

The second is to minimize the movements, which can reduce one to one. When excavating the soil, the bottom of the bucket is as parallel as possible with the soil layer, and then the small arm shovels the soil, and this action can dig more and dig more full. When throwing soil on the car, try to lift the big arm and dump the bucket to unload the soil, do not push the small arm, because then the soil piled on the bucket will fall down in advance.

Operation Techniques The first step is to check the surrounding conditions. During the rotation operation, be familiar with the surrounding obstacles and terrain and operate safely; Try not to put the final drive facing the excavation direction, otherwise it is particularly easy to damage the travel motor or soft.

Effective excavation method When the angle between the bucket cylinder and the connecting rod, the stick cylinder and the stick is 90 degrees, the excavation force reaches the maximum; Digging force is best when the bucket teeth are at a 30-degree angle to the ground, as this is when the soil is cut.

Digging rocks The use of buckets to dig rocks will cause great damage to the machine and should be avoided as much as possible; When it is necessary to excavate, the position of the body should be adjusted according to the crack direction of the rock, so that the bucket can be shoveled in smoothly and digging.

Slope leveling operation When carrying out plane trimming, the machine should be laid flat on the ground to prevent the body from shaking, and it is very important to grasp the coordination of the action of the boom and the stick, and control the speed of the two is very important for plane trimming.
