Contact suspension units combine robust construction with simple and reliable operation. When the light is in its raised and operational position the contact suspension unit automatically makes electrical circuits and engages “mechanical lock” consequently relieving the winch, pulleys and wire rope from tension.
Unlocking the unit to lower the light for maintenance automatically breaks electrical circuits therefore no live cables are lowered with the fitting.
Our contact suspension units can accommodate loads from 5KG-560KG with a maximum of 9 electrical contacts + earth feeding the luminaire. Just check out our animated video below to see exactly how the units operate.
