修理汽车发动机时,需将发动机从底盘上卸下装上。我们过去没有装卸发动机的设备,只好用人抬,既慢又不安全,往往影响汽车维修进度。在增产节约运动中,许多老工人都下决心解决这个问题。经过多次研究,最后吸取了老工人杨子玉同志的建议,自制了一台1.5吨活动式单臂吊(图5、6)。 When repairing a car engine, it is necessary to detach the engine from the chassis. In the past, we did not have the equipment to load and unload engines. We had to use people to lift them. It was slow and unsafe, and it often affected the progress of vehicle maintenance. In the process of increasing production and saving, many old workers are determined to solve this problem. After several studies, he finally learned from the advice of the old worker, Yang Ziyu, and made a 1.5-ton movable single-arm crane (Figures 5 and 6).
