Variable frequency drive motor reel for crane

1. Motor (with drive) Standard squirrel cage or torque motors, according to IEC Norms. Hydrodynamic cable reels can be supplied with a pneumatic or hydraulic motor.

2. Gearbox or Torque Unit Sever gearboxes and eight torque unites are available with variable output torque from 10-1200daNm.

3. Collector Standard sizes of collectors are available for power and signals. Current ratings vary from 10 to 2400Amp, voltages up to 30kV. We also manufacture customised collectors exceeding the above parameters.

4. The drums are composed of standard elements and can easily be adjusted to required widths. Standard drum diameters range from 300mm to 8700mm.

JARCH motorised cable reels are integrated in all potential ports crane applications, at the quay, at the yard or at the intermodal terminal. 

Typical applications:

• Ship-to-shore (STS) cranes.

• Automatic stacking cranes (ASC).

• Rail mounted gantry (RMG) cranes.

• Electric rubber-tyred gantry (E-RTG).

• Ship loaders.

• ShorePower systems.

The system provides the following functions:

Adopting frequency conversion control, the onboard PLC calculates the torque output to achieve constant tension on the cable.
The system operation and stop are controlled by the system operation signal.
The system feeds back three signals of "system normal", "system operation" and "cable full reel" to the PLC or the driver's room to protect the equipment and cables to the maximum extent, and facilitate the driver to monitor the working status of the system during operation.
In case of system failure, the system can be reset through the local and remote reset buttons.
Provide protection for empty and full cable reels.
