Twelve principles of safety excavator drivers must learn

[BONOVO]

First, each time when digging, the soil should not be too deep, and the bucket should not be too fierce, so as not to damage the machinery or cause overturning accidents. When the bucket falls, be careful not to impact the track and frame.
Article 2 Personnel who cooperate with the excavator to clear the bottom, flatland and repair the slope shall work within the turning radius of the excavator . If it is necessary to work within the rotation radius of the excavator, the excavator must stop the rotation and brake the rotation mechanism before it can work. At the same time, people on and off the plane should take care of each other and cooperate closely to ensure safety.
Article 3 Vehicles and pedestrians shall not be stopped within the loading range of the excavator . If unloading to the car, should wait for the car to stop, the driver leaves the cab, can turn the bucket, unloading to the car. When the excavator is turning, the bucket should be avoided from the top of the cab. When unloading, the bucket should be as low as possible, but be careful not to collide with any part of the car.
Fourth, when the excavator is rotating, the rotary clutch is used to rotate smoothly with the rotary mechanism brake, and sharp rotation and emergency braking are prohibited.
Fifth, the bucket has not left the ground before, shall not do rotation, walking and other actions. When the bucket is fully loaded and suspended, it shall not lift up or down the arm rod and walk.
Sixth, when the crawler excavator moves, the arm rod should be placed in the direction of the walking, and the height of the bucket from the ground should not exceed 1 meter. And brake the rotating mechanism.
Seventh, the excavator uphill, the driving wheel should be in the back, the arm rod should be above; When the excavator goes downhill, the driving wheel should be in the front and the arm rod should be in the back. The ascending and descending slope shall not exceed 20°. When going downhill, drive slowly, and do not speed up or glide in neutral. When the excavator passes through the track, soft soil and clay pavement, it should pave the plate.
Eighth, when digging loose soil on high working surface, large stones and other debris in the working surface should be removed, so as not to collapse and cause accidents. If the soil is dug into a suspended state and cannot collapse naturally, it needs to be treated manually, and it is not allowed to be smashed or pressed down with a bucket to avoid accidents. Ninth, excavator walking turn should not be too urgent. If the bend is too large, it should be divided into turns, each time within 20°.
Tenth, when the electric excavator is connected to the power supply, it must take out the breaker on the switch box. Non-electrical personnel are strictly prohibited from installing electrical equipment. When the excavator is walking, the cable should be moved by the staff wearing pressure rubber shoes or insulating gloves. And pay attention to prevent cable friction leakage.
11th excavator in the work, it is strictly prohibited to carry out repair, maintenance, fastening and other work. If there is abnormal noise, odor, or excessive temperature rise during the working process, stop the car immediately for inspection.
Article 12 When maintaining, repairing, lubricating and replacing the pulley at the top of the arm bar, the arm bar shall be dropped to the ground.
