What are the measures for handling power supply failures of bridge cranes?

he maintenance free capability of cranes is a common goal pursued by both users and manufacturers. There are also differences in the maintenance free capabilities of cranes as a whole and between various components. In addition, work intensity and working environment are direct factors affecting maintenance free capability. In the event of a power failure, in addition to the crane's self inspection and maintenance free capabilities, what are the requirements for the driver to provide guidance and assistance in handling emergencies in a flexible manner?

If a power failure occurs during the homework period, the driver should meet the following requirements:

1. When appropriate, apply the brake or install other safety devices.

2. All power sources should be cut off or the clutch should be in neutral position to avoid accidental operation after power is restored.

3. If feasible, the suspension load can be smoothly placed on the ground by controlling the brake.

4. At the beginning of each work shift, the driver should check all control devices. If abnormal operation of the control device is found, it shall be debugged and repaired before the hoisting machinery is operated.
