An elevator drive for use in a counterweight-less elevator installation includes a motor driving a traction sheave in engagement with an elongate load bearing member supporting an elevator car, and a pressure applicator exerting a normal force on the elongate load bearing member as the member engages with the traction sheave. One of the traction sheave and the pressure applicator is displaceable relative to the other. Accordingly, in use, the normal force imparted by the pressure applicator on the elongate load bearing member can be varied to improve the longevity of the elongate load bearing member.
