Abstract

The invention relates to an elevating work platform having at least one mast (3, 4), and at least one working platform (16) and/or lift car connected to the mast (3, 4) in such a way that it can move upwards. Said mast (3, 4) has at least one toothed rack (12, 13) running parallel to its longitudinal axis. The working platform (16) and/or lift car have at least one driving unit consisting of at least one driving motor (19) and one gearing (31). Said gearing (31) has at least one output pinion (24, 25) which meshes with the toothed rack (12, 13). The invention seeks to create an elevating work platform in which the load transmission from driving motor (19) to toothed rack (12, 13) is as constant as possible. To this end, the gearing (31) has an axis (35) fitted with at least one pinion (37) which meshes with a toothed wheel (40, 41). The pinion (37) and the toothed wheel (40, 41) have a spiral gearing.
