Abstract

A high speed engineering vehicle (10) has sprung axles located for vertical movement by linkage and locating arms and a suspension unit (15) between each axle and the body of the vehicle for high speed use, the suspension unit (15) including a compressible fluid medium providing both springing and damping action. The vehicle (10) also includes a suspension lock (16) with each suspension unit (15) to limit the vertical movement of the suspension unit (15) or to completely isolate it. Its preferred form comprises a hydraulically operated cylinder and ram attached to the chassis, and when required extends down to the axle to prevent vehicle movement relative to the axle, for example during digging operations. <IMAGE>
