Developed by WG Tanker Services engineers, the ground level coupling allows semi-trailer Suzies/palm couplings to be coupled/uncoupled from ground level - without the need to climb onto the tractor catwalk.
Connectors are mounted on pivoting arm fixed to the front of the trailer. For normal running the arm is secured in the vertical position. For coupling/uncoupling, the arm is quickly and easily hinged down, placing the connections at one side of the vehicle for easy coupling/uncoupling to/from the tractor unit.
Apart from the obvious safety benefits, as the tractor catwalk and access steps are no longer required, the operator has the opportunity to reduce vehicle unladen weight and purchase price.
Similar systems are now used by the major tank manufacturers.
