The electrical Control Cabinets are adequate for all kinds of port
cranes,tower cranes for architecture use, and overhead cranes in
the harbors,industrial enterprises and power stations. They can
cooperated with the controlconsoles to control the driving devices
to lift, rotate, change in radius, startthe bridge and trolley,
change directions and brake. Meanwhile the electricalcontrol cabinets can protect the power
supply, overload, the zero position andthe short circuit. The
electrical control start and control speed by switchingthe loop
resistors of the rotors, and can realize the braking and speed
controlby other energy consumptions. These electrical control
cabinets can be designed,manufactured, and installed and debugging
according to the clients’ requests. They can be used in the frequency control systems and PLC control
systems forthe driving and control of the cranes. |
