Abstract
A rope suspension apparatus for an elevator system, includes a bed, a motor 1 attached to the bed, a motor shaft 2, a traction sheave 4 so mounted on the shaft that the ends of the traction sheave are inclined at an angle relative to vertical, and at least one diverter pulley 5, such that at least one suspension rope 11 may run from an elevator car to the traction sheave via a route between the traction sheave and the diverter pulley. The arrangement provides that each suspension rope may, after passing around the traction sheave, 1 run to the respective one of the at least one the diverter pulley via a route proximal to that of the suspension rope going towards the traction sheave, and at least one counterweight may be suspended on the suspension rope below the diverter pulley wherein the traction sheave has been rotated substantially sideways by an angle substantially equal to the angle that the ends of the traction sheave are inclined relative to vertical.
