AbstractA goods vehicle has a body with upper and lower load-bearing floors and each mounted for vertical movement within the body. The upper floor is raised and lowered by a hoist. Telescopic links connect the two floors such that when the upper floor is less than a certain height above the lower floor it can move independently of the lower floor, but when the upper floor is lifted above such height it entrains the lower floor and the two floors move together. In another embodiment the two floors are fixed together for movement together over the full range of vertical movement of the upper floor.
