The unit consists of a wedge, which fully retracts into the ground to enable free access to passing vehicles but rising quickly to stop unauthorised entry.

The blocker is driven by a hydraulic power pack mounted remotely from the road blocker; which drives the wedge up by dual hydraulic rams. The power pack size sets the speed of operation and can range from 3.5 seconds to 6 seconds. And the power supply is either single phase 16 Amps or 3 phase 16 Amps.

The steel frame and structure is fully hot dip galvanised to AS 1650 to withstand corrosion and the road wedge is painted black with yellow reflective tape mounted on the front.

OPERATIONS
A remote contact closure eg. a card reader, push button or similar causes the road blocker to commence retracting and therefore opening up the driveway. Depending on the logic chosen, the blocker will either rest in the open position for a preset time before commencing to close or alternatively it will remain open awaiting a further command. The close cycle is essentially the open cycle in reverse. Safety devices i.e.: through beam and ground loop, inhibit closure if an obstacle is present.
