Heavy-Duty Systems

The requirements of container crane capacity have been increasing constantly in recent years. Trolley speeds exceeding 200 m/min are quite common, so that conventional cable festoon systems are bumping up against their technical limits.
 
Combined motor-driven and drive-less cable festoon systems serve as a cost-conscious solution to cope with ever higher trolley speeds and the associated load on the cable material. For careful handling of the cables, it is necessary at speeds above 200 m/min to provide some cable festoon systems with a drive in order to achieve better motion alignment between the crane trolley and the power supply. In the application, the number of motor-driven cable festoon systems depends on the individual crane and its technical parameters, e.g. trolley track, speed, acceleration, cable weight, number of runs etc.
 
The motor-driven cable festoon systems design developed by VAHLE distinguishes itself through its careful handling of the cables and its reliability. In particular, even under poor weather conditions, such as storms, snow or rain, the system has proven effective on previously equipped container cranes. For the large part, the maintenance is limited to a regular visual inspection.
