一台40 t汽车起重机吊钩配置存在缺陷,小钩失去功能,耗油量大,经过多次模拟试验,终于绘制出小钩科学合理位置的图纸。小钩原位置与既定位置相差近60 cm,只要将小钩拿下来平移到计算得出的位置即可。但钩头是由特种材料制成的,如果使用常规乙炔火焰割除,很有可能会使材质发生变化或扭曲变形。结合修理厂实际作业条件,决 A 40 t crane crane crane configuration defects, hooks lost function, fuel consumption, after many simulation tests, and finally draw a small hook scientific and rational position of the drawings. The original position of the small hook is about 60 cm away from the established position, just take the small hook and translate it to the calculated position. But the hook head is made of special materials, if the use of conventional acetylene flame cut, it is likely to make the material change or distortion. Combined with the actual operating conditions of the repair shop, the decision
