Hysteresis multi-motor cable reel for sts crane

Cable reel is a winding device used to transmit power, control power, or control signals between two relatively moving bodies of large mobile lifting equipment. It is widely used in heavy mobile machinery equipment such as port gantry cranes, container cranes, ship loaders, tower cranes, and similar working conditions.

   Hysteresis cable drum is currently the ideal winding equipment in cable winding devices. Compared with commonly used counterweight and torque motor cable drums, it has small volume, complete functions, convenient installation and maintenance, approximate constant tension, can adjust the output torque according to actual working conditions, and has good self control function without the need to install a brake. The cable drum operates reliably and can be blocked for a long time without damage.

2, Usage Environment

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.

Industrial Motorized Bridge and Gantry Crane Electric Power Cable Reel Drum Manufacturers

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.
