据用户反映W1001履带式起重机主卷扬刹车带断裂情况严重,90%以上产品,都有此现象,尤其是挖掘、拉铲作业,刹车带寿命更短,常常造成严重事故。为此,我们曾进行了一些试验、研究,现将情况作一简单介绍。刹车带强度分析: 已知卷扬机最大扭矩M_(KP)=2700公斤·米,刹车盘圆周力P=(2M_(KP)·K)/D=7384公斤式中K—冲击系数取1.3 D—刹车圆盘直径为95厘米 According to users’ reports, the main hoisting and braking belts of W1001 crawler cranes have serious fractures, and 90% of the products have this phenomenon. In particular, excavation and dragging operations have resulted in shorter life of brake belts and often caused serious accidents. To this end, we have conducted a number of experiments and studies. We will now briefly describe the situation. Brake band strength analysis: Known winch maximum torque M_(KP)=2700 kg·m, brake disc circumferential force P=(2M_(KP)·K)/D=7384 kg K-shock coefficient takes 1.3 D—brake Disc diameter is 95 cm
