1台QD16/3.2型电动双梁桥式起重机,由于存在驾驶室空间小、电气设备安全位置不合理、主钩升降过快,以及主梁发生下挠等问题,导致其存在一定的安全隐患。为了达到安全使用的目的,我们决定按照冶金行业起重机械的技术要求,对其进行改进与修复。1.改进方案(1)驾驶室内部空间及电气设备改进该起重机驾驶室内部空间及电气设备布置存在缺陷,具体表现在以下4个方面:一是驾驶室内部活动空间较小,操作人员不便操作;二是保护控制
A QD16 / 3.2 electric double-girder overhead traveling crane has some potential safety issues due to its small cab space, improper safety of electrical equipment, rapid rise and fall of the main hook, and underflexion of the main girder. In order to achieve the safe use of the purpose, we have decided in accordance with the metallurgical industry crane technical requirements, its improvement and repair. 1. Improvement Program (1) Cab Interior Space and Electrical Equipment Improvement The crane cab interior space and electrical equipment layout defects, specifically in the following four aspects: First, the cab interior space is small, the operator inconvenience Second, protection and control
