Abstract: An elevator in which the sheave diameter is reduced and the attendant lowering of the rope life and strength is suppressed to secure safety and reliability. To this end, a rope is used in which a plurality of element wires constituting the wire rope are each covered with resin material and the whole wire rope is covered with resin material, thereby reducing the wear due to slippage between the element wires and the wear due to contact with the sheave, which wear occurs when the rope is entrained around the sheave. When the elevator sheave diameter is reduced, a worried lowering of the rope life can be suppressed or the rope life can be improved. Thus, it is possible to achieve reduction of size and weight of equipment including motors and hoists, installation space saving for elevators, improved safety and reliability of the system by virtue of the increased rope life.

Abstract: An autobalancing roping and drive arrangement for elevators which continuously balances the weight of an elevator cab and the weight of a counterweight such that the force on the drive motor necessary to move the cab from floor to floor is minimized. A weighting device connected to a drive sheave imparts a downward force on the drive sheave and creates a tension in a force section, causing traction contact between the drive sheave and the drive rope. The tension in the force section includes a downward vertical component of force. This component and the weight of the counterweight combine to create a downward force on one side of the suspension sheave section. The downward force balances the downward force created by the weight of the cab on the opposite side of the suspension sheave section. The tension in the force section automatically compensates for the difference in weight between the cab and the counterweight and thereby maintains the elevator in balance.

Abstract: An elevator in which a dimension of an elevator shaft does not need to be increased when enlarging a hoist, and a position where a cage is suspended by a hoist cable can be flexibly selected. In an elevator according to the present invention, a hoist 10 is disposed such that a rotational axis thereof is vertically extended. Thus, when an axial dimension of the hoist 10 is increased to enlarge the hoist 10, a dimension of an elevator shaft does not need to be increased. Since a driving shaft 10a of the hoist 10 is vertically extended, an area occupied by the hoist is remarkably reduced when viewed in a horizontal cross-sectional view of the elevator shaft. Thus, the freedom to dispose the hoist 10 is enhanced so that a position where a cage 3 is suspended by a hoist cable 14 can be flexibly selected.

The invention has the following advantages. The vibration of inner car is reduced within an acceptable level for bringing a degree of comfort to passengers in the inner car while hoisting or lowering. The hoist ropes are prevented from slipping when a load of the car changes suddenly as in a case that many persons steps in or out of the car in a short period of time. An alignment of a bottom of the car with each of a plurality of levels is made possible when the elevator is stopped at each level. A manual escape device is provided for assisting passengers to escape in case of emergency.

Abstract: An elevator mechanism protects the control, communications, power, and/or lift cable(s) of the elevator system, precluding lateral cable movement within the elevator shaft. A slotted cable guide contains a cable therein, with the cable having a diameter larger than the guide slot to preclude escape of the cable from the guide. The upper end of the cable has a reduced diameter and extends through the guide slot, where it is supported by a lift bar extending from the elevator car and into the slot. A mechanism allows the lift bar to move laterally to preclude binding in the guide if the elevator car shifts laterally slightly. Another mechanism shuts down the system if the cable and/or cable reel jams. The present elevator mechanism is adaptable to virtually any type of elevator and lift mechanism, but is particularly useful with elevators used in tall, open structures.

Abstract: An embodiment of the invention is directed to a system having a pulley attached to a building. A closed loop of cable is installed around the pulley.

A winch around which the loop is to be operatively installed is located in the area next to the base. Other embodiments are also described and claimed.
