Summarize the nineteen-point safety management measures for cranes


Cranes are a type of special equipment. The safety management regulations for special equipment should be strictly observed. The safety management measures that cranes should take are as follows:

1. Don't pass the hoisted objects over the heads of other operators.

2. It is strictly forbidden to overload the hoisting operation.

3. Don't hang sideways.

4. Do not use the lifting limiter for lifting and parking.

5. Do not adjust the brake during lifting operation.

6. No overhaul and maintenance are allowed during operation.

7. It is not allowed to lift buried objects and diagonal pull operations when the lifting weight is unclear.

8. Do not dismantle or modify any safety devices on the crane at will.

9. Do not work under the following defects and damages that affect safety: brake failure, stopper failure, damage to the hook nut anti-loosening device, and hoisting wire rope damage that has reached the scrap standard.

10. Pay attention to whether the hook is directly above the load.

11. Pay attention to the safety of the front, back, left, and right sides during operation.

12. It is not allowed to carry out lifting operations under the conditions of loose binding, unbalanced lifting, easy sliding, and easy overturning, and the edges and corners of heavy objects are between the hoisting wire ropes without padding.

13. Do not work in the dim work place and the place and the suspended objects cannot be seen clearly.

14. When a fault is found, the main power supply should be cut off immediately.

15. When the heavy object is close to or reaches the rated load, it should be lifted and lifted steadily after a small height and short stroke test.

16. When the heavy object drops to 300 mm above the ground, stop and observe whether it is safe to descend.

17. Strictly implement the "Ten No Lifting" of lifting operations: do not hoist when the load exceeds the rated load; do not hoist the command signal or arbitrarily command; do not hoist the workpiece if the workpiece is not fastened firmly; do not hoist people standing on the hoisting object; do not hoist when the safety device fails; The workpiece is buried in the ground without hanging; the shackle workpiece is not hanging; the steel water ladle is too full and cannot be lifted; the edge object is not hanging without the liner.

18. For hoist-type cranes without descending stoppers, when the hook is in a low position, the wire rope on the drum must be guaranteed to have a safety ring of no less than two weeks.

19. The hooks and wire ropes must be checked before lifting. The hooks and wire ropes should meet the standards specified by the crane. The wire ropes and hooks that have been worn to meet the scrapping standards should be scrapped and updated.
