Hi Jeff
We fitted our Active Collision Avoidance System (ACAS) to 3 tonne Doosan Trucks at a brick manufacturing plant that suffered the same problem. If you would like more information please contact Transmon Engineering UK and ask for Steve or Pete we may just have the solution you are looking for. I take it most of the impacts are the drivers reversing into structures or the counterweight swinging into objects when reversing. www[dot]transmon[dot]co[dot]uk
