An assembly 28 for actuating and controlling braking of a car of an elevator system is provided. The assembly includes at least one braking device 20 mounted on the car, supported between the car and a hoistway for movement with the car within the hoistway, and configured to apply a braking force to the car. The assembly also includes at least one corresponding actuator 34 supported by the hoistway and configured to selectively engage the braking device to prevent movement of the car.

An elevator car frame, an elevator car and an elevator system. The elevator car frame includes a top, a bottom and uprights extending between the top and the bottom and deviating from a longitudinal middle portion of the elevator car frame, and at least one of the uprights is provided with car guide shoes arranged to enable the elevator car frame, after being installed in an elevator hoistway, to move along a car guide rail disposed in the elevator hoistway through the car guide shoes.

Provided is an electricity generating elevator, which includes a cage installed in a shaft formed in a building in order to carry passengers or loads, a drive unit vertically moving the cage along the shaft, and an electricity generation unit including a coil section installed on the cage and a magnetic force generator that is installed in the shaft so as to face the coil section and provides a magnetic force to the coil section so as to generate an induced electromotive force according to a change in a position of the coil section while the cage moves up and down. Thereby, the electricity generating elevator includes the coil section attached to the cage and the magnetic force generator arranged in the shaft at a position facing the coil section, so that electric energy can be produced by the coil section according to a change in a position of the cage while the cage vertically reciprocates in the shaft, and the produced electric energy can be used as a power source for vertically moving the cage. Thus, maintenance expenses of the elevator can be reduced.

The present disclosure is related to a travelling cable clamp assembly fixing an elevator travelling cable to a fixing base, such as to a first movable support structure in the hoistway for supporting said at least one elevator unit movable in the hoistway, including at least an elevator car.

A tension member for an elevator system has an aspect ratio of greater than one, where aspect ratio is defined as the ratio of tension member width w to thickness t (w/t). The increase in aspect ratio results in a reduction in the maximum rope pressure and an increased flexibility as compared to conventional elevator ropes. As a result, smaller sheaves may be used with this type of tension member. In a particular embodiment, the tension member includes a plurality of individual load carrying cords encased within a common layer of coating. The coating layer separates the individual cords and defines an engagement surface for engaging a traction sheave.
