Abstract

The safety lift comprises a vertical shaft of circular internal section, a cage, and means for supporting and driving the cage. There are access doors formed in shaft and cage. A screw thread is formed in the internal wall of the shaft (1), together with one or more axial guide grooves (6, 7). The cage (2) is annular, with a wall touching the shaft and large central windows, being equipped with bearings for the supports and drive mechanism, also protrusions engaging in the guide grooves. The supporting and drive mechanism is formed by one or more rings (14, 15) fitting on the cage top and bottom, and equipped with wheels (16) engaging in the grooves of the screw thread in the shaft wall. Motors drive the wheels in one direction or the other, causing the rings to rotate and raise or lower the cage.
