What are the precautions for excavator operation?

1 When the excavator is working, it should be parked on a solid and flat ground. The tire excavator should support its legs.

2, excavator should be in a horizontal position when working, and stop running mechanism. If the ground is muddy, soft and in danger of sinking, sleepers or boards should be used and properly padded.

3. When digging a bucket, it is not advisable to eat the soil too deeply every time, and don't lift the bucket too hard to avoid damaging the machinery or causing overturning accidents. When the bucket falls, be careful not to hit the track and the frame.

4, cooperate with the excavator operation, bottom cleaning, leveling, slope repair personnel, must work within the radius of gyration of the excavator. If it is necessary to work within the radius of gyration of the excavator, the excavator must stop gyration and stop the slewing mechanism before operation. At the same time, people on and off the plane should take care of each other and cooperate closely to ensure safety.

5, excavator loading activities, vehicles and pedestrians are not allowed to stay. When unloading in the car, wait until the car stops and the driver leaves the cab, then dump the bucket and unload in the car. When the excavator rotates, try to avoid the bucket from crossing the top of the cab. When unloading, the bucket should be as low as possible, but be careful not to hit any part of the car.

6, excavator rotation, the application of rotary clutch with rotary mechanism braking smooth rotation, prohibit sharp turn and emergency braking.

7. Before the bucket leaves the ground, it is not allowed to rotate or walk. When the bucket is fully suspended, it is not allowed to lift the boom and walk.

8, shovel, when shovel full, shall not continue to shovel, in case of overload. Digging ditches, canals, foundation pits, etc. With a spade, the distance between the machine and the slope should be determined through consultation with the construction personnel according to the depth, soil quality and slope.

9, backhoe operations, must wait for the stick to stop before shoveling, to prevent the bucket handle and the grooves on both sides of the stick from colliding with each other.

10. When the crawler excavator is running, the stick should be placed in the forward direction of walking, and the height of the bucket from the ground should not exceed 1 m.. And brake the slewing mechanism.

1 1. When the excavator goes uphill, the driving wheel should be at the back and the arm should be on it; When the excavator goes downhill, the driving wheel should be in front and the stick should be behind. Up and down slope shall not exceed 20. When going downhill, you should drive slowly, and speed change and neutral taxiing are not allowed on the way. When the excavator passes through the track, soft soil and clay pavement, the floor should be laid.

12. When excavating granular soil in the high working face, the large stones and other sundries in the working face should be removed to avoid collapse accidents. If the soil is dug into a suspended state and cannot collapse naturally, it needs manual treatment, and it is not allowed to be hit or pressed with a bucket to avoid accidents.

13, excavators are not allowed to get close to overhead transmission lines when working or walking. If it is necessary to work or pass near high and low voltage overhead lines, the safe distance between machinery and overhead lines must conform to the dimensions specified in Schedule 1. In thunderstorm weather, it is forbidden to work near or below overhead high-voltage lines.

14, when working near the underground cable, it is necessary to find out the direction of the cable, display it on the ground with white powder, and keep the distance of 1 m for excavation.

15, don't turn the excavator too fast. If the curve is too big, turn it several times, each time within 20.

16, tire excavator Because the flow of the steering vane pump is directly proportional to the engine speed, when the engine speed is low, the turning speed will slow down accordingly, so pay special attention when turning while driving. Especially when going downhill and turning sharply, it is necessary to shift down in advance to avoid the sudden decrease of engine speed due to the use of emergency braking, so that the steering speed cannot keep up with the accident.

17. When the electric excavator is connected to the power supply, the circuit breaker on the switchboard must be removed. Non-electricians are prohibited from installing electrical equipment. When the excavator is walking, the cable should be moved by the staff wearing pressure-resistant rubber shoes or insulating gloves. And pay attention to prevent cable wear and leakage.

18. When the excavator is working, maintenance, maintenance and fastening are prohibited. If there is abnormal sound, peculiar smell, excessive temperature rise, etc. During work, stop immediately for inspection.

19. When the pulley at the top of the boom is being maintained, overhauled, lubricated and replaced, the boom should land.

20. When working at night, the working area and cab should have good lighting.
