摘要： The present invention relates to a braking apparatus and an elevator system comprising the braking apparatus for grasping or gripping a hoisting rope of the elevator. The system comprises a pair of brake shoes, a motorized rotatable camshaft with at least one cam surface for pressing against a push plate to compress a spring means and keep the shoes apart or when the motor is disengaged cause the cam shaft to not push on the push plate such that the springs expand cause the brake shoes to come together and grip the hoisting rope.

摘要： An elevator cable safety brake is disclosed. The brake includes a first housing which is slidably mounted in a second housing. The first housing has an opening through which the elevator cables can pass. On one side of the elevator cables is located a first brake pad which is carried by the first housing. On the other side of the opening is located a second brake pad which is generally wedge shaped. The second brake pad is carried on a sled which is slidably housed within the first housing. The second brake pad may be moved between a free running position and a braking position. The wedge shaped second brake pad may be selectively released under certain trip conditions from the free running position to the braking position. Such conditions include the unintended overspeed operation of the elevator, a power failure, or the elevator commencing movement before the elevator doors are fully closed. A governor trips a trip lever effecting the release of the second wedge shaped brake pad. The slidable interaction between the sled and the first housing and the second housing enables the brake device to be self centering around the cables during the braking action. In an alternate embodiment the safety brake works in both the up and down directions.

摘要： The invention relates to a cable clamp for a cable of a lift system, having a supporting device which has a wedge receptacle with a first supporting surface and a second supporting surface which is arranged at an angle from the first supporting surface, and having a wedge-shaped clamping device which can be moved to and fro in the wedge receptacle between a clamped position and a released position and has a first clamping surface which lies opposite the first supporting surface and a second clamping surface which lies opposite the second supporting surface, wherein the two clamping surfaces are oriented obliquely with respect to one another. In order to develop the cable clamp in such a way that it makes repeated clamping and releasing of the cable possible with a compact design, without the mechanical load-bearing capability of the cable being impaired appreciably as a result, it is proposed according to the invention that the cable clamp comprises a deflection device and a first clamping region which is arranged between the first clamping surface and the first supporting surface and a second clamping region which is arranged between the second clamping surface and the second supporting surface, wherein the cable to be clamped can be guided through the two clamping regions and can be deflected by mean of the deflecting device from the first clamping region to the second clamping region.

摘要： A rigging, operable to raise and lower the platform, passes through a restraint device comprising a tension holder. The tension holder comprises a first body having a substantially planar face surface and a rear portion having a divot disposed therein. A second body, substantially similar to the first body; and having a substantially planar face surface; is disposed in a substantially facing arrangement with the first body to permit a line to pass between the substantially planar face surfaces. A lever is disposed in the divot of the first body and is operable to draw together the substantially planar face of the first body and the substantially planar face of the second body whereby friction can be selectively applied to the line when the line is disposed between the substantially planar first surface and said substantially planar second surface.

摘要： An emergency brake apparatus for an elevator system is installed on an elevator cage or a balance weight of the elevator system and includes a grip member with slant surfaces and a pressing surface sandwiching a guide rail, a pressing member disposed movably between the slant surfaces of the grip member and the guide rail, and an electric solenoid connected to the pressing member and actuated by an electric signal. The electric solenoid positions the pressing member away from the guide rail in a non-braking operation while pushing the pressing member between the slant surfaces and the guide rail in a braking operation.

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： In an elevator brake that includes brake jaws acting on at least one bearer rope and a device for applying the brake, the speed of the elevator car is monitored by an impulse relay. This relay is connected to a pulse generator that includes a roller driven by the bearer rope of the elevator car. If the speed of the elevator car is too high, a switching signal applying the brake is given before an arresting device responds.
