Precautions for use of electric chain hoist

 

1)Before installation, the electric chain hoist shall not be powered on for test run, and the newly installed electric chain hoist shall be unloaded for test run first

 

2) Before using the electric chain hoist, overload test shall be carried out. The methods and steps are as follows:

 

Static load test: lift the weight exceeding 25% of the rated lifting capacity 10cm off the ground and stay for 10min, then put down the weight and check whether each part is in good condition.

 

Dynamic load test: lift the weight exceeding 10% of the rated lifting capacity, lift and walk the weight for several times, then put down the weight, and check whether the mechanical transmission and electrical parts are normal.

 

Only after the static and dynamic load tests are qualified can it be put into use.

 

3) The use environment of electric chain hoist shall meet relevant technical requirements. General electric chain hoist shall not be used in flammable, explosive, corrosive, humid and hot environments.

 

4) The electric chain hoist is not allowed to overload the load, and it is forbidden to use the electric chain hoist to obliquely lift and drag heavy objects.

 

5) The height limiter of the electric chain hoist is a safety device to prevent the lifting of the hook from exceeding the limit. Therefore, the limit switch cannot be used to replace the normal operation.

 

6) When the electric chain hoist stops working, the heavy object shall be put down, and it is not allowed to hang the heavy object in the air.

 

7) After the operation of the electric chain hoist is completed, the power supply shall be cut off.

 

8) Under normal use, the electric chain hoist shall be checked and lubricated once every 10 days.
