Our patented Energy Absorbing Pole / Tree Buffers (EAPTB) are installed on fixed hazardous objects adjacent to busy roadways to absorb the impact of an out-of-control vehicle that may collide with the object. Our Energy Absorbing Pole Buffers have been deployed across South Australia, including at Tailem Bend (for the Coorong District Councl), at the Britannia roundabout in Kent Town,  Payneham Road, Glynde (for the City of Norwood) and Littlehampton in the Adelaide Hills. 

​

The Energy Absorbing Pole/Tree Buffers are a cellular design.  The singular cell is a round tube, strategically slotted for controlled crumpling and energy absorption.  The size and shape of the buffers are tailored to specific roadside hazards (such as power poles, trees or infrastrucutre) and the posted speed limit for the adjacent road.

​

On average, over 30% of collisions in metropolitan areas that result in fatal or serious injury involve a vehicle colliding with a fixed roadside object.  Energy Absorbing Pole/Tree buffers have the potential to significantly reduce our road toll.  Having undergone extensive testing to ensure they not only perform the function for which they were designed, but also meet all legislated Standards and associated Design Rules.  They are approved for use by Australian road authorities, including VicRoads and the Department for Infrastructure and Transport, South Australia.

The EAPB is protected by Australian Patent 2009202987.  Impact Absorbing Systems Pty Ltd is the sole manufacturer and supplier worldwide.  The EAPB is proudly Australian Made and is certified by the Australian Made Campaign Ltd.
