Solution: Swap positions of the two phase line

2. Electric chain hoist power failure

Failure: Power fuse is burned off or switch is off automatically without fuse burned
Solution: check if the current is within the rated scope, change a new fuse or restart the breaker.

3.Electric chain hoist Main line fuse faiure

Failure:　Main line fuse burn off
Solution: check the whole line and change new fuse

4. Electric chain hoist breakage

Failure: Breakage happen in chain hoist power line or control cabinet or unconnected
Solution: repair the broken cable or change new one or make sure all points in the control cabinet is 100% connected

5. Electric chain hoist voltage failure

Failure: Power supply voltage is too low
Solution: measure the voltage value to check if it is less than 10% of the rated power voltage

6. Electric chain hoist motor failure

Failure: The motor makes a sound, but it doesn't rotate.
Solution: Check if motor phase is correct - repair and make sure it is at good insulation state

7. Electric chain hoist emergent failure

Failure: Emergency switch has been switched on
Solution: found out the reason why the emergency switch is switched on

8. Electric chain hoist contactor failure

Failure: Contactor is not at 100% connected
Solution: operate the chain hoist manually, if the chain hoist can function in the right way, it means problem happened at wire coils or cables, find out the problem location and repair it; if the chain hoist still cannot function, it means problem happen at the main power source, found out the broken contractor and change with new one.

9. Electric chain hoist circuit failure

Failure: Contractor coil short circuit
Solution: change new contractor.
