WWII The Scammell SV-2S 6×4 is a pre world war two design. It has a single rear differential which drives into walking beams at each end of an "axle" tube. Each walking beam carries two road wheels which are driven by chains. This system has the great virtues of simplicity and excellent wheel articulation.


These trucks were used during world war two as recovery vehicles although their haulage duties were taken over by the likes of Diamond-T tractors.

Post WWII: This Scammell recovery tractor, FV1181(a), is a 6×6, having the rear walking-beam suspension (with one diff') and a driven front axle located by an A-frame, part-time 6×4 / 6×6.
