Abstract: The present invention relates to an elevator system for use during an emergency. The elevator system comprises two elevator shafts constructed adjacent to each other. Each elevator shaft houses an elevator car. The elevator system operates without the use of a building's power source by incorporating a primary pulley system to move the elevator cars. Generally, the elevator cars work in tandem such that as one elevator car goes up its respective elevator shaft, the other elevator car will go down its respective elevator shaft. Moreover, a secondary pulley system and a gear system are employed to also facilitate movement of the elevator cars without using the building's power supply.

The support device loops around the drive pulley at least partly and has a safety section which is so arranged that the safety section interacts with the drive pulley when the elevator car or a counterweight after overrunning an upper position approaches an upper shaft end. The safety section is formed in such a manner that a slipping through results due to the interaction between the drive pulley and the support device.

Abstract: In an elevator installation with an elevator car and a counterweight suspended and driven by several flat-belt-type suspension devices arranged in parallel, the suspension devices are arranged in parallel vertical planes that run diagonal to main horizontal axes of the counterweight and/or of the elevator car. Mounted on the counterweight and on the elevator car are suspension-sheave systems of which at least one comprises several suspension-sheave units which each have one suspension sheave and are arranged adjacent to each other, the suspension-sheave units being fastened to the counterweight and/or to the elevator car in such manner that the axles of the suspension sheaves are essentially horizontal and each are swivelable about one associated vertical axis.

Abstract: An elevator drive belt, while applying a friction force thereto, drives an elevator rope which links an elevator cage and a counterweight together. A rubber hardness of the belt ranges from about 50 to 90 degrees of JIS-A hardness so as to suppress creep slip due to a shearing strain while the elevator is in operation. Even if the elevator cage and the counterweight are reduced in weight and the friction force to be applied to the elevator rope decreases due to the weight reduction, a friction force onto the elevator rope from the elevator drive belt compensates and guarantees a drive force of the elevator.

A drive motor and associated drive sheave are disposed at a bottom portion of the hoistway. The drive motor is coupled to the elevator car and the counterweight via at least one flat rope for moving the elevator car upwardly and downwardly along the hoistway.

Abstract: A hydraulically-operated hoist is disclosed. The hoist includes a plurality of hydraulic piston/cylinder arrangements, each having an upper end. Two guide rails are disposed in parallel with the hydraulic piston/cylinder arrangements. A self-aligning yoke is connected between the upper ends of the hydraulic piston/cylinder arrangements and is raised and lowered along the two guide rails by the hydraulic piston/cylinder arrangements. The yoke comprises a beam with the two ends. An arm is connected to each end of the beam, extends obliquely upward from the beam, and terminates in a remote end rotatably connected to the upper ends of the hydraulic piston/cylinder arrangements. At least two sheaves are rotatably connected to the beam, each of which are capable of running its own wire line.

Abstract: A linear motor elevator includes a linear motor that is permitted motion within the hoistway. The linear motor is mounted in a manner permitting motion of the entire linear motor, including stator, through the hoistway. As a result, the length of the hoistway and the run of the elevator may extend beyond the length of the stator. In a particular embodiment, the linear motor is connected to a car in a configuration permitting the car to travel at approximately twice the speed of the linear motor within the hoistway. The moving element of the linear motor is connected to the car to permit the car and moving element to travel at the same speed relative to the hoistway. As a result, the moving element moves relative to the stator at half the speed of the car speed and the height of the hoistway may be approximately double the height of the stator.

Abstract: A rotating elevator motor provided with a traction sheave is placed in the counterweight of an elevator suspended from ropes. The sector-shaped stator of the motor has a diameter (2*Rs) larger than that (2*Rv) of the traction sheave and the elevator ropes are passed through the open part or parts of the stator. This structure allows the use of traction sheaves of dif ferent diameters with rotors of the same diameter. Still, the length of the motor remains small and the motor/counterweight of the invention can be accommodated in the space normally reserved for a counterweight in an elevator shaft. The motor shaft is placed in the counterweight substantially midway between the guide rails and the same number of ropes are placed on both sides of the rotor.

Abstract: An elevator having a car suspended by a rope in a 2:1 roping arrangement has a sheave for receiving the ropes and a structure for rotatably supporting the sheave. A flexible member is used to attach the structure to a car, which minimizes the transference of moments from the structure to the car. In addition, a damping material is used in mounting the flexible member to the car and support structure which reduces vibration and noise transmissions. Springs are also placed at the top and bottom of the flexible member to isolate low frequency vibrations in the vertical direction.
