Function:

The central distribution box assembly of the crane plays a central role in the electrical system of the crane and its main functions include the following:
1. Power distribution
The central switchboard assembly is responsible for distributing power to the various electrical devices of the crane, such as motors, lighting system, control system, etc. It distributes power to the different loads through its internal wiring and connectors. It distributes power to different loads through internal wiring and connectors.
2. Circuit Protection
The distribution box is usually equipped with fuses, relays and other protection devices, which can cut off the power supply in time when there are faults such as overloading and short-circuiting in the circuit, so as to protect the safety of equipment and personnel.
3. Centralised control
It integrates all kinds of electrical components in one box, which is convenient for centralised management and control. This design makes maintenance and inspection more convenient and the line more concise.
4. Isolation function
The distribution box can isolate the dangerous voltage and prevent the operator from touching the high-voltage part, so as to guarantee the safety of electricity.
5. Monitoring and Regulation
Part of the central switchboard of the crane also has monitoring function, which can monitor the operation status of the equipment in real time, find out the faults in time and protect them.
