一、力矩限制器的研制动态为了适应我国四个现代化建设日益发展的需要,工业与民用建筑施工所采用的塔式起重机的需要量越来越大。目前我国自行设计制造的塔机,通常未配备安全、可靠的力矩限制器。因此,在施工过程中往往发生超载倾复事故,给国家与人民造成重大损失,为此近年来国内的一些科研、教学、工厂与施工单位积极组织人员对力矩限制器进行了研制。 First, the development of torque limiter In order to adapt to the growing needs of China’s four modernization construction, industrial and civil construction of tower cranes used by the growing demand. At present, China’s own designed and manufactured tower cranes are usually not equipped with safe and reliable torque limiters. Therefore, overload dumping accidents often occur in the construction process, causing heavy losses to the country and the people. For this reason, in recent years, some scientific research, teaching, factories and construction units in China have actively organized personnel to develop torque limiters.
