Abstract
An elevating transport vehicle has its frame carried by steerable idler bogies and by drive wheels on an axle assembly having a mechanical drive via a telescopic drive shaft from an engine and transmission mounted on the frame. The drive axle assembly is supported beneath the frame by a pivotally mounted tie rod and swing arm at each side of the vehicle. Hydraulic cylinders act between the frame and the bogies and swing arms to raise and lower the vehicle frame and with a telescopic drive shaft from the first to the second drive axle assembly.
