SAB Gate

The SAB Gate is a modular ‘gate’ system for opening up the central reserve barrier on a dual-carriageway or motorway, to enable emergency vehicles to cross over, or traffic to be diverted in case of accidents or similar occurrences. Several units can be joined together to suit various opening widths. They are double-hinged, constructed from thrie beam with a lower rectangular rail all attached to a sturdy diaphragm framework.
Each unit has wheels which when deployed, allows individual sections or the complete ‘gate’ to be opened.
