An elevator system comprises a hoistway (4), an elevator car (2) arranged to move vertically within the hoistway and a drive machine (10) arranged in the hoistway outside the travel path of the car (2) or vertical projection thereof. The car (2) is coupled to the machine (10) by a rope (18) which is guided by a pair of idler sheaves (26, 28) so as to pass under the car (2). The idler sheaves (26, 28) have a diameter of less than 120 mm. The disclosed arrangement allows both overhead space and pit depth to be minimised.
