Product overview

The road blocker is ideal as a robust alternative to a fully impact tested road blocker it is available in widths up to 6m (increments of 500mm) and provides physical vehicle control and security for an establishment.

The blocker is operated by a hydraulic ram with the power unit (HPU) positioned locally within an externally rated cabinet. The blocker mechanism is encased in a sheet steel enclosure and has access points for onward connection to ducting for hydraulic hoses and control cables.

The blocker is constructed from heavy welded steel section to provide sufficient strength to exceed British axle loads.

The heavy duty durbar top plate is coated with safety markings, with removable access covers to enable efficient installation and servicing.

The blocker comes with a push-button control hold as standard, however it can be customised to interface with a wide range of access control equipment to suit specific customer requirements.

For safety reasons pedestrians, cyclists and motorcycles are advised not to use a blocker controlled roadway, additional safety measures can be incorporated into the blocker system if required. Where the road blocker control point is remote from the installation, we strongly recommend the fitting of a recordable CCTV system, traffic lights and safety inductive loop systems.

This is a specialist security product and is designed for use with vehicles only and a full site risk assessment must be carried out at design stage to ensure that all relevant safety systems are included.
