15 Things To Pay Attention To When Lifting Heavy Objects

15 Things To Pay Attention To When Lifting Heavy Objects

 

1. When lifting heavy objects, the wire rope of the hook should be kept vertical, and it is not allowed to drag the object obliquely.

 

2. The center of gravity of the heavy objects to be hoisted should be identified and tied firmly. The sharp angle should be padded with wooden skids.

 

3. Before the heavy objects are hoisted off the ground, the crane shall not perform slewing motion.

 

4. When lifting or lowering heavy objects, the speed should be uniform and stable to avoid sudden changes in speed, which may cause the heavy objects to swing in the air and cause danger. When dropping heavy objects, the speed should not be too fast, so as not to break the heavy objects when landing.

 

5. When the crane is hoisting heavy, try to avoid the lifting arm. When the boom must be raised and lowered under heavy lifting conditions, the lifting capacity shall not exceed 50% of the specified weight.

 

6. When the crane is slewing while hoisting, pay close attention to whether there are obstacles around. If there are obstacles, try to avoid or clear them.

 

 

7. No one should stay under the boom of the crane, and try to avoid people passing through.

 

8. Two bridge cranes with hooks work on the same track, and the distance between the two cranes should be greater than 3m.

 

9. When two hook bridge cranes lift an object together, the lifting capacity shall not exceed 75% of the total lifting capacity of the two cranes, and the two cranes must move and lift in the same way.

 

10. Lifting and luffing wire ropes need to be inspected once a week, and records should be made. The specific requirements should be implemented in accordance with the relevant regulations of hoisting wire ropes.

 

11. When the empty car is running or turning, the hook should be more than 2m above the ground.

 

12. When the wind exceeds level six, stop working immediately. The gantry crane must lay the iron wedge (rail stopper) and raise the hook to the upper limit.
 

At the same time, close the doors and windows, cut off the power supply, and pull the wind rope.
 

You should do the same after work is done.

 

 

13. It is strictly forbidden to stack miscellaneous objects on the crane platform to prevent falling and hurting people during operation. Frequently used tools should be placed in the special tool box in the operating room.

 

14. During operation, it is not allowed to change speed suddenly or reverse the car, so as not to cause heavy objects to swing in the air, and it is not allowed to activate more than two operating mechanisms (including auxiliary hooks) at the same time.

 

15. When driving, the operator's hands must not leave the controller. When a failure occurs suddenly during operation, measures should be taken to safely drop the heavy object, and then cut off the power supply for repair.
 

It is strictly forbidden to overhaul and maintain during operation.
