Higgs exhibit their automatic-lubrication system for rigid vehicles and an automatic system for semi-trailers operated by a flexible self-sealing coupling between the unit and the semi-trailer.
Automatic lubrication is carried out every 30 minutes by a transistorized timer operating via metering valves located at the necessary lubricating points.
If automatic lubrication is not required Higgs also market a hand-operated system both for oil and grease lubrication.
This system relies on the driver or maintenance staff providing the necessary manpower at the end of the day or required period to lubricate the whole vehicle with a few pulls on the lubricating pump.
