Power actuator – for maximum safety and comfort

A coupling with the VBG Power Actuator (PA) is opened and closed by means of a double-acting, pneumatically-controlled torsion device operated by a manual valve, with no need to reach underneath vehicle to access the coupling. This ergonomic solution is the most comfortable, and significantly simplifies coupling and decoupling. It saves you time and reduces the risk of injury.


The coupling is opened by hand and closes by spring force. This version does not require any additional components.

You can always supplement manual coupling with air-assisted opening (AM unit) or a power actuator (PA unit).
