ABSTRACT:
Elevating device, especially for raising and lowering the cabin of a transfer vehicle to the level of an aircraft hatchway, including an upright pusher chain mounted in a first guide sheath and connected at its upper end to the cabin. The first guide sheath is slidable within a second upright guide sheath mounted on the vehicle. A lower section of the chain extends through the second guide sheath to a driving sprocket. A link pin at the upper end of the lower section bears on the lower end of the first guide sheath so that as the chain is moved upwardly by the driving sprocket, the first guide sheath is extended from the second guide sheath and the upper section of the chain pushes the cabin upwardly. The links of the chain form a rigid pusher except that they are permitted to flex around the driving sprocket. The guide sheaths are fitted inside protecting and reinforcing telescopic masts extending between the chassis of the vehicle and the cabin.
