桥式起重机是现代工业生产中不可缺少的设备,但是,起重设备在使用过程中存在很多危险因素,引发了许多工伤事故。据有关部门的统计,我国每年起重事故伤亡人数占全部工业企业伤亡人数的15％左右,因而,有必要对起重设备的运行进行检测。然而,目前我国不少生产部门使用的起重设备缺少检测手段,针对这种情况,我们与有关劳动监测部门配合,设计了起重机载重数显及超载报警装置。 Bridge crane is an indispensable equipment in modern industrial production. However, there are many dangerous factors in the use of lifting equipment, which has caused a lot of work-related accidents. According to the statistics of relevant departments, the annual number of accidents caused by crane accidents in China accounts for about 15% of the total number of industrial enterprises and casualties. Therefore, it is necessary to test the operation of lifting equipment. However, at present, the lifting equipment used by many production departments in our country lacks detection means. In response to this situation, we work with the relevant labor supervision departments to design crane-mounted digital and overload alarm devices.
