ABSTRACT
Over a five-year period, there were at least 18 documented cases of ascending elevators striking the overhead [1]. In some cases, the accidents resulted in serious injuries or fatalities. These accidents occurred on counterweighted elevators as a result of electrical, mechanical, and structural failures. Elevator cars are fitted with safeties that grip the guide rails and stop a falling car; however, these devices do not provide protection in the upward direction.
Rules and regulations applying to elevator safety have come under review in response to these accidents. Some governing authorities have already revised their regulations to require ascending car overspeed protection. This paper will discuss basic elevator design, hazards, regulations, and emergency braking systems designed to provide ascending car overspeed protection. In addition, a case-study report on a pneumatic rope brake system installed and tested on a mine elevator will be discussed.

在五年期间内，至少有打击在头上的 [1] 的上电梯的 18个被证明的情形。 在一些情形，意外事件造成了严重的受伤或伤亡。 这些意外事件电、机械、和结构的失败结果在平衡物的电梯上发生了。 电梯汽车配备有抓紧引导者栏杆，而且停止一辆落下的汽车的安全; 然而，这些装置不提供向上的方向的保护。
规则和适用于电梯安全的规则已经在审核过程中回应这些意外事件来。 一些统治主管当局已经校订他们的规则了需要上汽车超速保护。 这纸将会讨论刹系统的基本的电梯设计、危险、规则和紧急设计提供上汽车超速保护。 除此之外, 一项个案研究报告在空气的粗绳刹车安装而且测试一个我的电梯的制度将会被讨论。
自己翻吧，不要懒，这种事没人愿意干的。
