Hoisting Machines: Safety Installation and Operation Procedure

All kinds of hoist machines are widely used in the installation, modern building and municipal construction and projects. Not only safety technology and usage is a vital link for hoisting equipment but also it is an important factor for ensure the construction producing quality.

    

1. Before installation, dismounting and delivery, technicians and workers with practical experience should research and make out program. The last but not least, it is necessary to them to communicate with operators about the technical factors. During operating, the workers must be concentrated and comply with the unified command.

2. Pay attention to the construction surroundings and check whether there are dangerous location, overhead power line and other obstacles in the working area. If necessary, to set up a restricted zone and appoint special-assigned persons to guard is sensible. According to the regulations, operators should use the relevant protective articles and tools.

3. In order to ensure safety, all the stressed rod pieces, steel wire ropes, raising power and anchoring equipments should proofread their load-capacity strength at first.

4. The diameter of all steel wire ropes must be over φ12.5mm should be used and special anchor blocks are needed. It is not allowed to fixed on the poles, trees or scaffolds. Included angle between dragging and the ground had better less than 45°. If necessary, ground anchor laying depth should be added appropriately, so that it can increase the pressure the pressure in the vertical direction.

5. Steel wire ropes for lifting are available for using handling latches and all of the latches should be kept in the same direction. U-shape bolts with 5~6 times intervals are fixed on the end of wire ropes, which has pressing plate on them.

6. Should there are acute contacting points between rigging and weight, jute bags, rubbers and planks must be applied to supply. In addition, it is wise to decrease breaking force according to deformation angle of steel wire ropes.

7. As for the hoisting equipments in position or after shifting place, a test-lifting is deliberate before loading weight. If there were variation or risk, hoisting machine operators should put the weight down and adopt reinforcement or other measures.

8. It is not allowed to stand or walk in the inside triangle area during the tow rope and sheaves are under stress.

9. If you are one of the members of overhead crane operators, you had better pay attention to the hooks and steel wire ropes. The load should be tied up firmly and keep it in vertical direction and in right gravity center. It is prohibited for anyone to stand on or under the load.

10. When operating the hoisting equipments, the crowbar should be in appropriate size. The fulcrum is suggested to use firm components, which is difficult to be in sliding when prying the load.

11. When you are using the chain block to handle with the hoisting machine, it is not allowed to be overload. It is wise to apply with them based on the rated lifting capacity.

12. Before lifting, you should check whether the hook, chain, gear in good condition.
