我矿汽车队自制了一台八吨电动千斤顶,改变了长期来使用四吨手摇千斤顶修理汽车的落后状态。过去修理汽车时,用手摇千斤顶把一个轮子顶起,该部件修好后再顶起另一个轮子。工效低,也不安全。为此,汽车队何永祥同志寻找资料想办法,经过多年试验改进,自制成功八吨电动千斤顶(见图)。使用二年多来效果良好。既安全又提高工效四倍。 My mine car team made a eight-ton electric jack, changing the long-term use of four tons of hand jacks to repair the backward state of the car. When repairing a car in the past, use a jack to jack up a wheel and the part is repaired and jacked up another wheel. Low efficiency, not safe. To this end, Commander He Yongxiang Automobile Team looking for information to find a solution, after years of testing and improvement, self-made eight tons of successful electric jack (see photo). Use more than two years to work well. Both safe and improve work efficiency four times.
