Abstract (en)
[origin: EP0117862A2] 1. Lifting appliance, in particular nacelle (1) of generally rectangular, powered, suspended type, able to move upwardly and reversely along a facade wall or a bulding, characterized in that, on the one hand, along its lengthwise centre, are aligned a motor (2) able to be connected through a first transmission shaft (3) with a coupling-reversing device (4), for example controlled by means of a pneumatic jack, this coupling-reversing device being connected through a second shaft (5) with a case (6) containing a reduction unit intended to change the driving motion into a right-angled one, said second transmission shaft (5) bearing between the coupling-reversing device (4) and the case (6) containing the reduction unit, a flywheel (7) which is integral with said shaft and can be decelerated and blocked by means of a braking device (8) with jaws (9, 9') acting on the flywheel and the opening of which can only be obtained through a pressure exerted on a control means, this case containing said reduction unit driving, on the other hand, perpendicularly to the transverse alignment and on both sides, a third transmission shaft (10, 10') at the ends of which is located a lifting wheel (12) on which in each case passes a chain (14, 14') fastened along a building.
