Modular Elevator With a Self-Propelled Cabin on a Mast

The modular lift with a motorised cabin on a mast of the type that incorporates traction through the pinion-rack with the mast made from a structural tube as a carrying part (1) and a cabin (2) provided by a frame with the rolling and guiding parts of the lift (5), pinions (7), the tractor groups (6) and the control button panel (8) integrated into it, is characterised because all this together is integrated into a parallelepiped shape closed on all sides in which it has been planned that the motorised groups (6) are placed in inverted positions to each other with the effect of eliminating the risk of pinion (7) and rack (4) disengaging. This also facilitates access to the respective release levers as they are close to each other, assisting how they work with the attack pinions (7) that are as far away as possible from each other but close to the rolling guides (5), guaranteeing the complete engagement of the pinion with the rack independent of the irregularities of the carrying part. Also, the pinions are wider than the rack (4) and each motorised group is protected by a metal cover (23) which also provides protection for the people in the cabin at the same time from being accidentally trapped in the moving parts. In addition, this facilitates access to the motors (6) from inside the cabin with the covers (23) having oval holes cut in them where the release levers for the motor brakes come though.
