Heavy duty motor driven cable trolley
VAHLE
Trolley speeds exceeding 200 m/min are quite common, so that conventional cable festoon systems are bumping up against their technical limits.
New approaches have been introduced to cope with the ever higher trolley speeds and the associated load on the cable material. A combination of motor-driven and drive-less cable festoon systems represents one cost-conscious solution. 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.
