Abstract:
An elevator system comprising:a cage hoisted in an elevator shaft by a rope; a counter weight hoisted by the rope; a traction machine having an uppermost extent and a lowermost extent with respect to vertical movement of the cage in the elevator shaft, located in the elevator shaft at a position higher than a cage stopping position at an uppermost floor of travel of the cage, having a driving sheave rotating around an axis and around which the rope is passed, and a motor for driving the driving sheave to move the cage and counter weight vertically in the elevator shaft; and a deflector wheel rotating about an axis and having upper edge and a lower edge, with respect to vertical movement of the cage in the elevator shaft, wherein the upper edge of the deflector wheel is lower in the elevator shaft than the uppermost extent of the traction machine, the lower edge of the deflector wheel is higher than the lowermost extent of the traction machine in the elevator shaft, the deflector wheel is spaced from the traction machine in a plan view of the elevator shaft, the rope extends upward in the elevator shaft, passes partially around the deflector wheel and the driving sheave, and, thereafter, extends downward in the elevator shaft to the cage, and the axis of rotation of the driving sheave forms at least one of (i) a first angle of inclination with respect to the axis of rotation of the deflector wheel in a horizontal direction, and (ii) a second angle of inclination with respect to the axis of rotation of the deflector wheel in a vertical direction.
