Raising the safety game

An evolution of ATV and quad rollover protection, the AR quad safety bar uses compressed gas and an electronic control system to offer fully automated, pneumatic roll-over protection – with full deployment in less than 250 milliseconds.

As well as offering ‘active’ protection, the system also uses positional sensors to deliver passive information to the rider, using visual and audible signals to alert that the machine is reaching a stage where stability is about to be compromised.

The protective structure is a triangular tubular structure mounted to the rear carrier and the towbar, that in normal use sits lower than the rider, so does not raise the machine’s centre of gravity. If activated, the structure telescopes vertically and laterally, locking out mechanically at full extension and creating a ‘safe zone’ under the machine.

The manufacturer claims that the device will stop the machine rolling beyond 90 degrees from vertical, preventing a full rollover, while at the same time reducing any consequential damage.

Built by Spanish manufacturer Air Rops, the system is said to be compatible with most ATVs with independent suspension and meets regulatory standards, being certified by SGS, CE-marked and type approved by external notified bodies.

The overall design also meets OECD standards for agricultural tractors and ISO 3471 for machines with a mass of 300 to 5,000kg.
