What Should Excavators Pay Attention To In Different Working Scenarios?

1, soft zone or water operation:

When working in the soft soil zone, we should understand the degree of soil looseness, and pay attention to limit the excavation scope of the bucket, to prevent landslides, landslides and other accidents and the deep subsidence of the vehicle body.

When working in water, the water depth allowed by the vehicle body should be noted (the water surface should be below the center of the sprocket); If the horizontal level is high, the internal slewing bearing will result in poor lubrication due to the entry of water, the engine fan blade will be damaged by water, and the electrical circuit element will be short circuit or open due to the intrusion of water.

2. Lifting operation:

The hydraulic excavator should confirm the surrounding conditions of the lifting site, use high strength hook and wire rope, and try to use special lifting device when hoisting. The operation mode should be micro-operation mode, and the action should be balanced slowly; The length of the rope is appropriate, too long will make the hanging object swing larger and difficult to accurately control; The position of the bucket should be adjusted correctly to prevent the steel rope from slipping; The construction personnel should try not to get close to the hoisting objects to prevent the danger caused by improper operation.

3, smooth operation method:

During operation, the stability of the excavator can not only improve the working efficiency, prolong the life of the machine, but also ensure the safety of operation (put the machine on the flat ground); Drive sprocket in the rear side is better than in the front side stability, and can prevent the final transmission from external force impact; The wheelbase of the track on the ground is always greater than the wheel base, so the forward working stability is good, to try to avoid side operation; Keep the dig site close to the machine to improve stability and excavator; If the digging point is far away from the machine, the operation will be unstable because the center of gravity will move forward. Lateral digging is less stable than forward digging, and the machine will be more unstable if the digging point is far from the center of the body, so the digging point should be kept at a suitable distance from the center of the body to make the operation balanced and efficient.
