ZZHZ has very rich experience of producing gantry crane, therefore it gives some advice to operate the electrical system safely:
1. When the gantry crane runs abnormally, the operator must stop the machine to look for the reasons, and remove the faults.
2. When the faults of electric system occur which need to be checked and repaired, the operator must stop the power. The work with electricity is prohibited strictly.

8. If the glide-hook of lifting mechanism occurs, the maintainer must find out the reason and deal with it in order to avoid the accident.
9. The equipment shouldn't be used in lightning storm.  The operator should cut off the power, and the machine should be moved to the place which has grounding line, and at the same time the worker shouldn't stay around the machine.
