time:Oct 19,2016
The electrical parts of the lifting crane machine includes two aspects, namely the power system and the control and protection system.
Power system: When the lifting crane machine is connected to the power supply externally, it needs to use the electric box. After adjusting the voltage and current, it is allocated to different electrical components on the crane, such as the traveling mechanism, the trolley mechanism, and the lifting system.
Control and protection system: The lifting crane machine needs to control the components, the electrical system is also part of the control system. In addition, in order to ensure the safety of the crane, when there is an electrical fault, the power can be disconnected in time to ensure the safety of personnel and equipment.
Common electrical protection devices include:
1. Grounding protection
2. Interlock protection
3. Short circuit protection
4. Overcurrent protection
5. Emergency switch
6. The main isolation switch
