Precautions For Gantry Crane Operation

1. When lifting heavy objects, the hook wire rope 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 sharp changes in speed, which will 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 personnel shall stay under the boom of the crane, and try to avoid the passage of personnel.
8. Two cranes work on the same track, and the distance between the two cranes should be greater than 3m.
9. When two 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 lifting 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. TMK should turn the boom to the downwind direction and lower it properly, and hang the hook firmly. 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 you finish your work.
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 start two or more operating mechanisms (including auxiliary hooks) at the same time.
15. When driving, the operator's hand must not leave the controller. When a failure occurs suddenly during operation, measures should be taken to safely land the heavy object, and then cut off the power supply for repair. It is strictly forbidden to overhaul and maintain during operation.
16. The crane shall not be lifted if one of the following conditions occurs
a. The heavy object exceeds the rated lifting capacity of the crane.
b. The weight of the heavy object is unknown.
c. The signal is unknown.
d. The heavy objects are not tightly bound.
e. Open-air operations encounter severe weather such as strong winds, heavy rain, and heavy fog above level 6 (level 5 on the beam).
f. The lighting for night work is not good.
g. cable pull.
h. The steel wire rope is severely worn and broken, and someone is overhauling it on the crane or in the machine room.
