Terminal Tractor
The workhorse in the port.

Terminal tractors are used in ports, logistics centers or on industrial sites for handling mainly semi-trailers, container chassis, roll trailers and heavy-duty trailers. Depending on the area of application, they are also known as RoRo tractors or, due to the adjustable fifth wheel, as lifting semi-trailer tractors.

In addition to the conventional drive with diesel engine via a powershift transmission either on one or on two drive axles, the use of REFUdrive inverters can turn the conventional terminal tractor into a "yard horse" with zero emissions.

The diesel engine together with the powershift transmission is replaced by a drive unit consisting of a traction inverter and electric motor. Auxiliary units such as hydraulics, compressed air and air conditioning of the cabin are also driven by REFUdrive inverters.

Thanks to the compactness of our RPCS730 inverter family, the area between the axles can be used for sufficiently large battery storage to ensure equivalent operation of the terminal tractor to a conventional diesel drive without disadvantages.

REFUdrive solutions can be used in both diesel-electric and battery electric versions.

Power electronics from REFUdrive

  • 1 x RPCS 730 150K traction inverter for one drive axle
  • 1 x RPCS 730 150K traction inverter for second drive axle for 4x4 drive
  • 1 x RPCS 730 28+4K combination inverter for the hydraulic lifting gear and auxiliary drives and supply of the 24 VDC and 12 VDC components
  • SAE-J-1939, CANpur (CANopen), cross communication for fast control functions between inverters for synchronization, e.g. speed, load sharing and energy management

Optional for diesel-electric operation: 1 x RPCS 730 150K generator inverter

Optional: 22 kW on-board charger

Optional: External 220 kW DC charging station for high-speed DC charging22 kW on-board charger

REFU systems support and are compatible with all common asynchronous and synchronous motors. Also  complete systems incl. motor can be provided. Optimal motor control systems reduce energy consumption and thus, in addition to reduced maintenance costs, significantly lower the TCO.
