Abstract: An elevator system includes a hoistway and an elevator car positioned in and movable along the hoistway. The elevator car includes a first sheave and a second sheave spaced apart from the first sheave. The first sheave and second sheave have parallel axes of rotation and each include a traction surface and a gearless prime mover operably connected to the traction surface to drive rotation of the traction surface. A first load bearing member is positioned in the hoistway and a second load bearing member is positioned in the hoistway. The first load bearing member passes laterally under the first sheave, vertically upward between the first sheave and the second sheave, and laterally over the second sheave. The second load bearing member passes laterally under the second sheave, vertically between the second sheave and the first sheave, and laterally over the first sheave.

Abstract: A support member configured for use in a machine room of an elevator system is provided including a base having a car end and a counterweight end. The counterweight end is arranged substantially parallel to a wall of the machine room, and the counterweight end is arranged at an angle relative to the car end. An idler sheave having a plurality of grooves is mounted to the base in an orientation generally parallel to the car end. The idler sheave is configured to rotate about a first axis of rotation. A plurality of individual sheaves is mounted to the based in a staggered configuration substantially complementary to the angle of the counterweight end relative to the car end. Each individual sheave is configured to rotate about a second axis of rotation parallel to the first axis of rotation.
