The lifting platform assembly has at least two scissors structures (20,22) and a drive. The drive has a motor (52) with a rotating spindle (54) with at least one keyed spindle nut (56). The spindle nut or the motor is linked to a connection point (44) of the scissors bars (24,30) of the lower and upper scissors structures.
