The current modernization of port installations and the increasing handling performance result in ever higher energy demands. For the power supply systems, this means larger cable cross-sections and higher voltages, higher travel speeds and acceleration values.
Today, flexible 20 kV high-voltage cables with fiber optical cores are used as energy carriers for such power supplies, which are managed under normal operation by cable reels. Apart from the high-voltage cables for longitudinal travel, additional cables are frequently used for control, communication or data transmission. Additionally, cable reels are used for the vertical operation of spreaders, magnets, grabbers etc.
The following components ensure trouble-free operation:
- Reel body for monospiral and multi-layer drum cable winding
- Drive with variable frequency technology ensures constant cable tension which protects the cable
- Slipring body installed in heatable enclosure for corrosion protection
- Guide roller assembly with tight and slack cable monitoring for defined cable deposit
