随着建筑施工电梯在国内的普遍使用,施工电梯中的一种重要安全保护装置——离心式限速制动器越来越引起有关单位的重视。1985年,上海市建筑科学研究所、上海交通大学对由该所设计、上海宝山建筑机械厂制造的DXQ型单向限速制动器进行了性能测试工作。一、测试目的和要求为使该类型限速制动器达到设计要求,确保施工电梯在超速运行和发生意外事故时起安全保护作用,必须对其主要技术性能进行测试:1.限速制动器制动时的额定限制转
With the widespread use of building construction elevators in China, centrifugal safety brakes, an important safety protection device in construction elevators, are increasingly attracting attention from relevant organizations. In 1985, the Shanghai Institute of Building Science and Shanghai Jiaotong University performed performance tests on the DXQ type unidirectional speed limit brakes designed by the Institute and manufactured by Shanghai Baoshan Construction Machinery Factory. 1. Test purpose and requirements In order to achieve the design requirements for this type of speed limit brake, ensure that the construction elevator will play a role in safety protection during speeding and accidents, and must test its main technical performance: 1. When the speed limit brake is braked Rated limit transfer
