Abstract: A vehicle lift device comprises structure 23 which is fixed to the chassis beneath the vehicle floor 11, a parallel linkage 21 carrying a platform 50 and connected to the structure 23 for movement at a level beneath floor 11 about vertical axis 22 so that the linkage and platform can be moved between an operative position extending from the vehicle and a stowed position beneath the vehicle floor 11. A single ram 40 can move the linkage up and down for raising and lowering a load, for example a wheel-chair, to permit the load to be moved on to the floor through a doorway which is not obstructed by the lift device. The platform can be collapsed for storage and the linkage has nesting members 35a, 37 for resisting possible injury.
