汽车起重机吊臂在超载情况下,可能会发生折弯变形的事故,导致其中一节臂变形而不能使用。对此,可以焊接修复。经过多年的修理经验,发现此方法实际可行。经过修复后,能达到吊车使用的技术参数要求。本文针对这个情况,对以后类似情况可以忽略做拉伸、硬度试验,直接采用本文介绍的方法来修复吊臂,这样缩短维修时间,使起重机尽快地正常运转,降低损失。
Truck crane boom in overload conditions, bending deformation may occur accident, resulting in deformation of one arm can not be used. In this regard, welding repair. After years of repair experience and found that this method is feasible. After the repair, can reach the technical parameters of crane requirements. This article in view of this situation, after similar situations can be ignored to do stretching, hardness test, directly using the method described in this article to repair the boom, thus reducing maintenance time, so that the crane as normal as possible to reduce losses.
