Transfer carriage with battery drive

Transfer carriage with battery drive: flexible and autonomous

Demag drives make the right moves – with perfectly matching components for an efficient overall system.

With our components for battery-powered transfer carriages, we can offer you a self-sufficient solution in which the charging and power unit is already integrated on board. All Demag drive components can be used with their full performance features for battery-powered systems.

Extend the range of your travel applications, e.g.

Rail-bound transfer carriages with the ability to overcome gaps at crossings
Indoor and outdoor applications where the power supply cannot be laid due to obstacles
In painting booths and other areas that are not suitable for an electric power supply
As a cost-effective solution for long travel paths – without the need for additional cabling & wiring for the power supply
For emergency power supply to vertical applications
