Abrégé

An elevator system includes a hoistway, an elevator car movable along the hoistway, and a power management and transfer system. The power management and transfer system includes an electrical power source, a hoistway contactor secured in the hoistway and operably connected to the electrical power source, and a car contactor disposed at the elevator car, such that when the car contactor is brought into operable contact with the hoistway contactor, electrical power is transferrable between the power source and the elevator car.

During a maintenance inspection, an optical rope diameter measuring device is provided at a predetermined position along a path of a wire rope, rope diameter is measured at multiple measuring points while the elevator is driven in test mode, and diameter reduction at each measuring point is determined and stored as a first diameter reduction (S2_S6). During a subsequent maintenance inspection, rope diameter is similarly measured at each measuring point to determine diameter reduction constituting a second diameter reduction (S7_S11). Based on these two diameter reductions, the time at which diameter reduction will reach a predetermined threshold value is predicted for each measuring point, and the earliest time is displayed as a rope replacement time (S12_S14).

An elevator car (1) which moves vertically along the hoistway is provided with a roller guide assembly (3) guided by a guide rail (2). The roller guide assembly (3) is provided with a horizontal stationary shaft (8) which is affixed to a base member (6) and rollers (5a, 5b, 5c) which are supported by the horizontal stationary shaft (8). The rollers (5a, 5b, 5c) are each provided with a roller outer peripheral section (10), a rolling bearing (9), annular rubber (11), and an inner tube (12). The configuration eliminates the need for a conventional spring or a conventional damper mechanism because the rubber (11) deforms elastically.
