The barrier stands 1160mm above foundation level with the boom 960mm above foundation level. The high duty cycling 24vdc linear actuator connects to the drive shaft via a torsion arm providing an operating speed of approximately 10 seconds. An industrial grade gas strut is used to provide additional counterbalancing and dampening thus giving a smooth operation.
The steel cabinet is shot blasted, primed and powder coated (RAL1007) and houses the control panel, linear actuator with manual winding facility and the limit switches. Barriers with booms in excess of 5m or where collapsible skirts are fitted require end supports to aid boom rigidity.
