Prohibited work and precautions for hydraulic excavators

Hydraulic excavators are widely used in various work sites. However, if they are not used safely or improperly used, they will not only damage the car, but also cause serious accidents. Let's take a look at what the hydraulic excavator can't do and which ones are dangerous:

Prohibited work and precautions for hydraulic excavators

1 to prevent foundation collapse

The most used hydraulic excavators spare parts are loading and excavating earth and sand rock operations. Excavation of the earth under the foot during excavation may cause landslides due to excessive weight support. Therefore, it is necessary to confirm the condition under the vehicle body during excavation work. It is very important to dig too close to your feet. I feel that I may dig too much and push the car back a part. Correct the foundation under the foot and dig up to what extent will it collapse? Also due to the nature of the soil, the soft soil, the place with a lot of water is dangerous. Before the operation, it is necessary to confirm the strength of the earth. If necessary, compact the earth under the foot. To prevent the landslide under the foot, the effective method is to excavate the surface. Set the angle of repose on the angle, the angle of repose is within 35 degrees and can not be larger. When excavating, the car walking system is at right angles to the excavation surface, and the collapse of the ground under the foot is also easier to escape. The operation of the car walking system parallel to the excavation surface should be avoided as much as possible:

1 The lateral length of the walking system is shorter than the front-rear direction, so the vehicle body is easily emptied and the stability is poor when excavating.

2 When the excavator spare parts is carried out, the inclined surface is subjected to load, so that the foundation under the foot is easy to collapse.

When the landslide begins at 3 feet, it is not easy to escape.

2 prohibiting the hitting of the working device

The use of the force of the falling force of the working device to crush the stone with the tip of the bucket should be strictly prohibited. The broken stone pieces are scattered and are very dangerous to the driver and the surrounding staff. Moreover, this method can significantly shorten the life of the working device, especially the excessive load on the bucket.

The method of crushing large stones by using a working device bucket to dig up the stones should be prohibited. The scattered stone pieces after breaking are very dangerous.

3 Prevent collision between bucket and dump truck

What should be noted in the dump truck loading operation is to prevent collision with the excavator and the dump truck. First of all, after the dump truck arrives at the loading position, it must be very careful. When the reverse truck approaches the loading position, the excavator spare parts driver must give a parking signal. Otherwise, the dump truck driver does not know that the parking position continues to reverse and will hit the excavator's working device. Another point to note is that it prevents the collision of the dump truck during the turning. If it is unskilled, the collision between the dump truck and the excavator may occur due to the excessively fast or inadvertent safety confirmation.

4 Prevent loose plunging

5 Take care to avoid obstacles such as boulders

6 Prohibition over the allowable water depth

7 Pay attention to the loading of large stones https://jnjmzm.wixsite.com/sdjygcjx
