igus® has further enhanced its e-rover, a system that enables automatic coupling and decoupling to/from the energy chain system. Energy and data can therefore be securely supplied by cable – including via FOC cables at Gigabit speed. The coupling process only takes about a minute and there are no restrictions on the RTG’s speed. Once the RTG has been ‘plugged in’ to the energy chain system, the diesel-based energy supply stops. Cables with a cross section of 180 mm² per phase can currently be used. Compensation of horizontal and vertical differences.
The system works using a telescopic arm on the RTG, which can extend and retract. This has two benefits: firstly, it enables automatic coupling with the energy chain, in which all media are simultaneously guided, is moved with the RTG. This guarantees the supply of energy and data. Secondly, horizontal and vertical differences and misalignment's in the travel can be balanced out. The system is suitable for long travels – with 1,640 feet and more being conceivable depending on customer requirements in the container port.
