In container ports and holding terminals around the world, rubber-tyred gantry (RTG) cranes are employed for handling standard containers. These cranes are designed for continuous operation at high handling rates, providing dense container stacking and offering high selectivity.
However, continually rising diesel prices and mounting environmental pressure against noise and pollution have combined to make conversion from diesel drive to electric power attractive. Meeting all the requirements to supply the RTG crane with both power and data, in a safe manner that is also almost maintenance-free, is the innovatively-designed igus E-Rover.
E-Rover is suitable for long travels, usually of 800m, but it is possible for it to be longer, with compensation of lateral offsets to within +/-400mm or according to customer specifications. Data transfer is interference-free and can be used with the full range of igus bus cables or, for higher speeds, igus fibre-optic cables.
According to igus, the E-Rover is unique in that it can carry different media (power, data, fluids, etc) together in a single system. As with all igus systems, the E-Rover is virtually maintenance-free and can be used even in harsh environmental conditions.
