Container Crane with Long-Traveling e-chain®

Rol-energy chain reduces drive power by 75%

long travel cable carrier Cable Carrier -longitudinal travel of 441.3 m Rol-E-Chain 5050 all stainless steel housing

An igus® cable carrier system with a 1,447 ft (441m) travel is being used for two container cranes at a coal power plant in Malaysia. Coal is unloaded from ships by two large container cranes and transported the 1.2 miles (2 km) to the power station by conveyor belt. The terminal has the largest capacity for unloading bulk goods in South East Asia. The quay of the new terminal is about 2,723 ft (830m) long and 66 ft (20m) deep, so ships as big as the Panamax and Capemax can dock. The container cranes unload the coal at docking stations on a man-made island situated approximately 1.2 miles (2 km) offshore. They can unload up to 1,500 tonnes per hour.

Cable carriers from igus® were selected for the two container cranes at the terminal. They were installed as a fully pre-harnessed readychain® cable carrier system to supply energy and data to the trolley and cabin ride.
