The unit for lifting the movable base includes a rack system, a pantograph, or a threaded rod mounted on bearings, where the threaded rods are driven in rotation by a belt acting on the gear wheels. The base comprises a linear guide unit such as pads. The panels are engaged in the mobile profiles forming the uprights, where the uprights have notches for engaging the panel in a direction orthogonal to the plane of the side wall. The driving unit is manual or motorized by a crank, a reducer, or a winch. The driving unit comprises a locking device for maintaining position of the movable bottom.
