一、摔坏起重物的原因及防止措施1.摔坏起重物的原因发生摔坏起重物的主要原因是由于卷扬刹车失灵所致。其原因:①刹车带被雨水浸湿(车顶棚漏雨)或沾染油污,刹车时制动力不足;②刹车带的摩擦材料严重磨损,露出铆钉,刹车时发生打滑现象;③卷扬刹车液压分泵皮碗损坏漏油,或油管漏油,刹车时制动力下降。如果在起重作业前已发现刹车带被水浸湿,起重机又急等用,可启动发动机,让传动
First, the reasons for breaking heavy lifting and prevention measures 1. Causes of breaking the lifting gear The main reason for breaking the lifting gear is due to the failure of the winding brake. The reasons are as follows: 1 The brake belt is wetted by rain (rainfall on the roof canopy) or contaminated with oil, and the brake force is insufficient; 2 The friction material of the brake belt is heavily worn, the rivets are exposed, and the brake slips when braking; 3 The hydraulic pressure of the brake The pump bowl damaged the oil, or the tubing leaked, and the braking force was reduced during braking. If the brake belt has been found wet before the lifting operation and the crane is in urgent need of use, start the engine and let the drive
