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