1. There are specific requirements for the specifications of the steel plates produced by cranes, allowing cranes to be used within the plate thickness range;
2. Attention should be paid to the use conditions of cranes for hoisting workpieces or the environment. Special cranes should be used for lifting and cranes with special cranes for use and symbols for use and use.
3. Ordinary workpiece hoisting can be operated by ordinary crane operators, but the operation of suspending and suspending the workpiece must be carried out by a qualified person with a special suspension and loading operation;
4. It is forbidden to knock or collide with hanging objects and spreaders;
5. Do not exceed the rated lifting capacity of the illegal lifting operations, must use the crane to hoist the workpiece within the allowable load range;
6. During the crane permitting process, it is forbidden to move sharply or stop sharply.
7. It is forbidden for the operator to approach the hoisting work piece or the hanging and passing area;
8. The illegal operations of stage lifting, heavy lifting, horizontal grabbing, co-hanging, and leaning objects are all not allowed;
9. It is strictly prohibited to use the work overload;
10. For the sake of safety, two or more spreader clamps can be used to avoid heavy lifting;
11. Lifting steel clamps need to be carefully inspected before use, check before use, eliminate the bite condition, solve the gasket, tooth clogging, regularly check the wear status and other abnormal phenomena.
