施工升降机在建筑、路桥、水利、电力等工程建设的很多行业得到广泛使用,经常因为管理使用不当和故障得不到及时处理使事态扩大甚至导致伤害事故。本文主要介绍其故障类别与危害性、常见故障原因与排除方法,对同类机型的管理、使用、维修和检验工作有一定的参考价值。1故障类别与危害性施工升降机的故障分类及危害度系数见表1。2故障原因与排除方法1)金属结构连接失效在施工升降机顶升过程中不按照操作规程操作,操作与管理方面的疏忽,如立柱的标准节上节连接螺栓不定期紧固,在立柱顶升过程中临时使用升降机,不及时安装上升限位和极限开关就 Construction lifts are widely used in many industries such as construction, road and bridge, water conservancy, electric power and other engineering construction. Often they are enlarged or even caused injuries due to improper management and improper handling of faults. This article mainly introduces the types and hazards of its failure, causes and solutions of common failures, the management, use, maintenance and inspection of similar models have some reference value. 1 Fault Categories and Hazards The classification of construction lifts and the hazard coefficient in Table 1.2 failure causes and troubleshooting 1) the failure of metal structure connection in the process of lifting the construction elevator operating procedures in accordance with the operation, operation and management negligence , Such as the standard section of the upper section of the column connecting bolts from time to time fastening, the temporary use of elevators in the process of lifting the column, not in time to install the rising limit and the limit switch
