Title: Goods lift arranged on a staircase
Inventor: BRAUN DANIEL
IPC: B66B9/08
Filed: 1988-12-22
Abstract: A goods lift arranged on a staircase moves on a path which occupies part of the step width (1) in order to convey persons or loads, without impairing the movement of other persons on the staircase and without having visible mechanical elements, from one stair landing to another. The goods lift has a carriage (16) which moves on two parallel rails (4a, 4b) resting on the steps (1) of the staircase. The carriage (16) is equipped with two lateral pinions mounted on a common shaft driven by an electric motor.
