With the e-rover, igus
has produced a system that automatically couples rubber-tyred gantry cranes
with an energy chain system. A telescopic arm connects the trough guided energy
chain to the RTG. Thus, providing guaranteed energy supply and data
transmission through standard and fibre optic cables.
RTG’s (rubber-tyred gantry cranes) are mobile container
bridges, which can switch between the container corridors. Usually, these RTGs
are fuelled by diesel. To save energy costs and to protect the environment,
developments in the past years moved towards electric vehicles that are coupled
to an energy supply system once they are in a traffic lane. igus GmbH has developed
its e-rover to enable automatic energy chain system connection and
disconnection. Thus, allowing energy and data to be supplied safely in cables
and fibre-optic cables with Gigabyte speeds. The coupling process takes about a
minute, with no limits to the travel speed of the RTG. Once the RTG has been
"plugged in" to the energy chain system, the power supply via the
diesel mode is discontinued. Currently, cables having a cross section of 180
mm² per phase are feasible.

Balancing of the
horizontal and vertical unevenness
The system works via a telescopic arm on the RTG, which
can retract and extend. This has two advantages. Firstly, an automatic coupling
is possible, and the energy chain in which all media can be routed
simultaneously, pulled along by the RTG. Hence, the supply of energy and data
is guaranteed. Secondly, the horizontal and vertical irregularities and offsets
in the travel path can be compensated. The system is suitable for long travels – 800 metres and possibly longer
depending on the customer requirements in the container port.

Once the RTG has been attached and "plugged"
into the energy chain system, the energy supply via the diesel operation is
discontinued, thus conserving energy and the environment. (Source: igus GmbH)
