摘要： A device and procedure for creating and securing a temporary safety space within an elevator hoistway such that a service or maintenance technician can work with impunity from a car entering the safety space. In particular, the device includes a stop bar for installation between and in engagement with opposing guide rails of the hoistway to prevent upward or downward movement of the car or a counterweight.

摘要： An adjustable brake is provided that applies a braking force directly to an elevator sheave over which a cable suspends an elevator car and a counterweight. The brake includes a pair of calipers that apply a braking force to either longitudinal end of the sheave. The brake is spring set and may be released using, for example, electromagnetic, hydraulic or pneumatic forces. The calipers are mounted to and movable along a rail to enable adjustment of the location of the calipers. Further, the calipers are coupled together using one or more pins and are movable along the pins to enable adjustment of spacing between the calipers. The brake is particularly adapted for use with existing elevators because the brake does not require modification to the existing elevator sheave.

摘要： A device provides an elevator installation with a shortened car travel path to establish a temporary protective space below and/or above the car upon activation of the car safety brake device. The speed limiter cable is limited, independently of the speed limiter, in a travel path by a switchable stop device. This limitation causes an actuation of the car safety brake device in the corresponding travel direction.

摘要： A lower rate of wear of brake blocks and a speed limiter cable for a lift speed limiter brake apparatus and thus a longer service life can be achieved with a cable brake having brake blocks of different materials. In a preferred embodiment, one of the brake blocks is of aluminium-bronze and the other brake block is of nodular cast iron or soft cast iron. In further embodiments, one or both of the brake blocks may be formed of a ceramic-containing material.

摘要： The invention concerns a method for braking a traction sheave elevator. To stop the elevator in the event of an emergency, the braking of the elevator is complemented by using a braking device not comprised in the drive machine. The invention also concerns a traction sheave elevator provided with a braking device not comprised in the drive machine and designed to improve the efficiency of emergency stopping. The maximum force decelerating the elevator and generated by the braking device equals about half the weight of the nominal load of the elevator.

摘要： An elevator includes a special propelling fluid dynamic device which uses as a plunger the duly balanced car counterweight. The car conveys people and things upwards and downwards within a vertical conduit or hoistway supported by a cable extending to an upper pulley. When changing the direction, a counterweight is extended to balance the car. The pulley is supported from the hoistway walls and is kept in a freely-rotating condition while the balanced counterweight is a hollow piston-counterweight, accommodated in the cylinder vertically disposed in the hoistway itself and adjacent to the car. Both are integral with the propelling fluid dynamic device that produces the upward and downward movements of the car, which is completed with a circuit having a fluid flow conduit and a driving pump coupled to the valve mechanism.
