IWA 14 – 7.2t @ 40mph

The IWA14 reduced height Terra G8 Sliding Cantilevered Gate, successfully impact tested with a 7.2t vehicle travelling at 40mph (64kph). On impact, the gate stopped the vehicle within the aperture.

The gate leaf is constructed with a Heavy Duty Crash Impact Beam and Heavy duty posts support the gate leaf. The Cantilevered Gate, requires no track or support across the roadway, therefore no roadway excavation needed. The balance is provided by a unique enclosed “runback”, which enables the gate to be fully projected across the roadway without tipping

Electronically controlled motor drive unit. Designed for ease of installation and maintenance.

The reduced height Terra G8 Sliding Cantilevered Gate can be interfaced to any access control systems.

  • Maximum width: 8000mm
  • Based on the Terra G8 Gate IWA14 Tested dimensions : width 8000mm

    Warning and information signs installed on the barrier boom such as ‘STOP’ ‘NO EXIT’ and ‘NO ENTRY’

    Pedestrian Warning Sign

    Normally placed on the barrier cabinet. Warns pedestrian of the automatic barrier.

    Traffic Light System

    Traffic Light systems are highly recommended to be installed with all road blocker and bollard systems to advise all users of its position. 100mm traffic light head can be pole or mounted on control cabinet

    Vehicle Detector Loops

    Vehicle detector loops installed beneath the road surface to detect vehicles. This will prevent the automatic equipment from closing on a vehicle within the aperture. Safety induction loops cut into the road surface. This will prevent the gate from closing on a vehicle within the aperture.

    Safety Photocells

    Safety Photocells produce beams of light which cross the road way to monitor vehicle and pedestrian movement. If an object breaks this beam, the automatic equipment will stop & reverse. On gate installations, two pairs of photocells are usually fitted. Ultra Sonic Sensors are also available.

    Gate Safety Edge

    Safety Edges are normally fitted to automatic gates. However they can also be installed beneath a barrier boom. Safety edges prevent the barrier lowering on a person or vehicle in the event it is activated. Safety edges are flexible strips which, if depressed, send a signal to the power source to stop.

    Pedestrian Guard Rail

    A Pedestrian Guard Rail (fence panels) should be fitted around the runback area of the sliding gate. This is to prevent serious injury to a person should they stray into that area whilst the gate is operating.


    Sounders/Audible Alarms provide an audible warning that the automatic equipment is in operation.

    Flashing Beacon

    Flashing Beacons provide a visual warning that the automatic equipment is in operation.

    UPS – Uninterrupted Power Supply

    In the event of a power failure or sabotage an interrupted power supply system can open and close the Terra Gate for a number of predetermined operations is available.
