Product Information

ATG Access is pleased to announce that we have successfully designed and tested the new and innovative Guardian Road Blocker.

The Guardian Road Blocker is a market leading, innovative shallow mounted 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 Road Blocker is straightforward 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 installing traditional road blocker structures.

One fundamental feature which makes this product so different from previous road blocker products is the unique counterbalance 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 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.

Key Points:

  • No large cabinets required. Unique counter balance mechanism reduces the requirement for hydraulic power. A small integral pump is utilised to raise and lower the product.
  • Installation is straightforward and cost-effective, only requiring a single concrete pour.
  • The blocker’s top plate is made from a unique structure ensuring longevity when heavy vehicles drive over the blocker regularly.
  • The Guardian has been designed for fast and easy servicing with a safety skirt offered as an optional extra.
  • Raise & lower time – 5 seconds up and 5 seconds down.
