Operation test and process of electric chain hoist
Electric chain hoists can be installed on suspended I-beams, cantilever cranes and fixed lifting points to transfer goods. They can also be used in low workshops and places that are not suitable for bridge cranes, as well as places where wire rope electric hoists are too large. use. The electric chain hoist must be tested for operation before use. The steps are as follows:
Operate the button switch and directly press the down button to operate the crane to descend until the limit spring touches the limit switch, at which time the motor automatically stops.
Press the up button directly until the chain is completely retracted into the chain bag and the motor stops running.
Test the emergency stop switch function.
Check the lubrication of the lifting chain.
Check the directionality of the chain purpose, all the welding points should be in the same direction. Only when all the chain welding points are on the same line can the correct operation be completed.
The operation process of the electric chain hoist is as follows: Before operating the equipment, the operator must have a clear view of the entire working area without any obstacles.
Before operating the equipment, the user must check the entire work area for safety hazards.
When using a motor to drive the trolley, the operator must be careful to avoid that when switching the direction of the trolley, the lateral reverse force caused by the swing of the load may exceed the load of the trolley.
