Energy chain
With its own drive
Long distances, high dynamics, long running times - these are the characteristics of the new Drive-Chain. Igus has designed it for rail-mounted automated stacking cranes (ASC) in ports.
The huge overhead cranes cover distances of several hundred meters and more. The motor cables usually follow the movement of the cranes. Because high pushing and pulling forces act on the chains at lengths of more than 1,000 meters, Igus has developed the energy chain with its own drive - the first manufacturer in the world to do so. The E-Chain follows the movement of the ASC crane with its own drive, so that hardly any loads occur. So-called drive swords in the outer radius drive the chain in the lower run. There are motor-driven friction wheels on the sides and rollers on the top of the lower rail. When the crane moves off, the friction wheels start their motors. The lower run moves along the rail. Igus is already working on an alternative drive concept in which the friction wheels are replaced by linear drives.
