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.
