The stack container has two support arms (3) fitted to a vertical support plate (2) which is moved vertically between two vertical, profiled guide rails (4). The plate has two parallel axles supporting four wheels, with two wheels in each guide rail to support the container without tilting. A tethered chain (12) in a side groove (8) of the guide rails is engaged by gears (16) on one axle. The gears are driven by a control motor, coupled to the drive shaft by a belt or chain drive. The motor is of a self-locking type. |
