Safety operation procedures for excavators

1. Before the excavator is started or operated, signal should be given; After the engine is started, it is forbidden to stand in the bucket, boom, crawler and hangar.

2. No one is allowed to stay in the excavator operation area. Irrelevant personnel are prohibited from entering the excavator operation room. No one is allowed to get on or off the machine or transfer objects. It is not allowed to shelve anything that interferes with the operation. It is not allowed to work during repair and maintenance.

3. The working position must be flat and fixed. Before work, the crawler should brake, the tire excavator should prop up its legs, the tire should leave the ground, the direction of the car body should be consistent with the extension direction of the excavation surface, and the bucket should not be too deep or too hard during operation.

4. When excavating earthwork with stones in high slope working face, larger stones and sundries should be removed. If the soil is dug into suspension and cannot collapse naturally, it needs manual treatment. It is forbidden to smash the hanging earthwork with a bucket.

5. It is forbidden to smash (break) solid objects with buckets. It is also forbidden to use rotating machinery to break solid objects in the bucket. In case of large stones or hard objects, they should be removed before operation; It is strictly forbidden to dig rocks above level 5 that have not been blasted.

6, it is strictly prohibited from the top of the cab bucket of earth-moving vehicles. When unloading soil from an earth-moving truck, the height of the bucket should be lowered to prevent the load from being unbalanced or damaging the carriage.

7. It is forbidden to arrange excavators in the upper and lower mining sections (surfaces) to operate at the same time; When moving in the working face, you should first level the ground and remove obstacles in the road; If you move on soft ground, you must pad the upper wood under the walking device.

8. It is forbidden to lift the excavator when the bucket joystick or bucket cylinder is fully extended. When the bucket doesn't leave the ground, the excavator can't travel laterally or rotate.

9. It is forbidden to work under high-rise structures such as wires and stay in a space full of buckets for a long time.

10, it is forbidden to use the excavator boom to drag heavy objects on the side; It is forbidden to use the sudden drop and impact of the working device of the hydraulic excavator for excavation.

1 1. When the excavator walks, when it meets wires, intersections, pipelines and bridges, it must be commanded by a special person, and the distance between the excavator and the high-voltage line shall not be less than 5m; Walking backwards should be avoided as much as possible.

12. When walking, the boom should be parallel to the crawler, the turntable should stop, and the bucket should be about1m off the ground; Downhill should be exercised at low speed, and sliding at variable speed is prohibited.

13. The parking position and walking route of the excavator should keep enough safe distance from the road surface, ditches and foundation pits to avoid slipping.

14. When the excavator needs to stop on the slope, the bucket must touch the ground, all the joysticks should be in the middle position, and a wedge should be placed behind the track or tire.

15. When excavators are working around telephone poles, attention should be paid to protecting electrical facilities such as wires, optical cables, poles and their stay wires, cement piles, etc.

16. When digging near underground optical cables and working in urban areas, you must know the distribution of underground cables and pipelines in detail, and it is strictly forbidden to work blindly.

17. before the excavator enters the pond or wades across the river, it is necessary to master the geology and bearing capacity to prevent the machinery from getting stuck in the car.
