摘要： An overspeed safety braking mechanism for lift cars and elevator systems is described herein. The safety mechanism may comprise a safety kit secured to an overhead portion of a lift car, and configured to engage a cable to prevent a downward movement of the lift car. Engagement of the cable may occur when a threshold speed is reached. The overhead portion of the lift car is detachable upon a predetermined upward force resulting from an engagement of the safety cable from the safety kit. A primary brake system may be positioned beneath the safety kit, on or near a lift platform, configured to engage the safety cable in response to an activation of the safety kit and a detection of the threshold speed.

摘要： An overspeed governor assembly for an elevator system, an elevator safety system, and an elevator system. The overspeed governor assembly comprises an overspeed governor, a linkage provided to enable the overspeed governor to associate with a safety device of the elevator, when an elevator car overspeed is occurring, to trigger the safety device to perform safety measures, and at least one torsion spring coupled between a sheave and a centrifugal mechanism in the overspeed governor for providing a pre-set load, and the centrifugal force formed by the centrifugal mechanism when the elevator car overspeed is occurring, is greater than the pre-set load, for triggering the safety device via the linkage.

摘要： An elevator anti-fall buffer based on flexible guidance. The anti-fall buffer is used for connecting and fixing an end part of a braking steel rope of an elevator. The anti-fall buffer has an upper support plate and a lower support plate, wherein a pulley set is provided on the upper support plate and the lower support plate, and a hydraulic damping buffer is provided at two sides of the pulley set. The anti-fall buffer uses the energy consumption principle of a hydraulic damping hole, and while protecting the braking steel rope from the force of impact created thereon by the elevator, prevents the force of impact from a spring on the elevator post-braking, improving the safety and reliability of elevator braking, thereby improving safety of an elevator, while also using a pulley set can increase the braking distance of the braking steel rope, thereby lengthening life of the steel rope.
摘要翻译：基于灵活引导的电梯防跌落缓冲器。防跌落缓冲器用于连接和固定电梯的制动钢丝绳的端部。防跌落缓冲器具有上支撑板和下支撑板，其中在上支撑板和下支撑板上设置有滑轮组，并且在滑轮组的两侧设置有液压阻尼缓冲器。防跌落缓冲器使用液压阻尼孔的能量消耗原理，同时保护制动钢丝绳免受电梯产生的冲击力，防止电梯后制动时弹簧的冲击力提高电梯制动的安全性和可靠性，从而提高电梯的安全性，同时使用滑轮组可以增加制动钢丝绳的制动距离，从而延长钢丝绳的使用寿命。

摘要： The present invention relates to an elevator wire rope braking apparatus, and more particularly, to a rope braking apparatus which prevents partial abrasion of the wire rope while increasing braking efficiency by preventing a deviation in the pressure applied to the wire rope by a pressure plate moving in a straight line to apply pressure to the wire rope. Since the pressure application is based not on a hydraulic method but on a purely mechanical structure using only a spring elastic force, environmental pollution caused by hydraulic oil may be prevented and product cost may be reduced.
摘要翻译：电梯钢丝绳制动装置技术领域本发明涉及一种电梯钢丝绳制动装置，更具体地，涉及一种绳索制动装置，其通过防止由于压板移动而施加到钢丝绳的压力的偏差来提高制动效率，防止钢丝绳的部分磨损以直线向钢丝绳施加压力。由于压力施加不是以液压方式为基础，而是基于仅使用弹簧弹力的纯机械结构，可以防止由液压油引起的环境污染，并且可能降低产品成本。

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 car braking system in which a pair of brake shoes engage and grip the hoisting ropes, part of the hoisting apparatus or the car guide rails when compressed springs, which are normally held in a compressed state by an electrically operable locking assembly, are released. The springs are compressible by a fluid operable piston and cylinder assembly. The springs move a cam follower, linked to one of the shoes, along cam surfaces shaped and disposed to cause the cam follower to move one brake shoe toward the other brake shoe. The locking assembly is responsive to car speed and/or movement of the car from a floor with its doors open. Switches operable by the cam follower control the car electrical controls so that movement of the car is prevented when the springs are not compressed and when there is excessive shoe wear.

摘要： A cable lock shoe is provided that has a side portion that includes sections that are arranged at a slight angle with respect to each other. Thus, the angle of the cable side of the shoe is parallel to the sloping side of the shoe from a point centered with the cam center line and this permits the shoe to clamp the cable when it moves upward without increasing pressure on the cam.
