Guardian Road Blocker


We are pleased to annouce the addition of a successfully designed and tested, new and innovative road blocker.

The Guardian Shallow Mounted Road Blocker is a market leading, innovative road blocker successfully impact tested to the new IWA 14 standard arresting a 7,200 kg truck (7.2 ton) at 80 kph (50 mph) achieving less than 1m of penetration. After impact, the installed structure of the blocker remained intact and was able to be easily re-commissioned.

With an installation foundation depth of just 400 mm total depth required, this high security road blocker is shallow mounted. The Guardian is straight forward to install requiring only a single pour of concrete and a simple rebar structure, which reduces the cost of civil works considerably. Also minimises the time needed on site in comparison to install traditional road blocker structures.

One fundamental feature which makes this product so different from previous road blocker products is the unique counter balance mechanism utilised within the design. These mechanisms reduce the need for hydraulic power allowing the use of a small, integral power unit and removing the need for large above ground cabinets. This also substantially reduces power consumption ensuring that this product utilises energy sustainably.

The blocker’s top plate is exceptionally rigid when driven over, greatly improving reliability; it is also energy absorptive when impacted. The top plate comprises of a layer structure of greatly reduced steel and a high tech polymer giving far greater longevity even when being driven over by heavy vehicles on a regular basis. The product is designed for fast and easy servicing.

This revolutionary blocker has been designed to be an industry leader in terms of price, technology and serviceability; a clever piece of engineering from the ATG Access team producing a very strong and versatile blocker.
