The SYSTEM MARATHON design is a combination of festoon and energy chain system and it consists of energy chains with rollers for long travel. The upper part is guided with roller sets on continuous flat treads, whereby the sliding friction between the upper and lower chain part is completely avoided. In front of the chain radius the roller sets are lifted out of the guide rail. In the chain radius the roller sets are pivoted into the trough by means of polygonal shape and the chain is lowered in the trough. In the opposite direction of travel, the roller sets behind the chain radius swirl again, embrace the guide rail and carry the upper strand centered within the trough. Applicable in STS, RMG, RTG, Unloaded, Stacker Reclaimer systems.
