多绳摩擦提升机的传动原理一直是依据欧技传动原理公式，如图1所示，即，T1＝T2eμαT1为重载侧各钢丝绳张力之和，T2为轻载侧各钢丝绳张力之和。防滑安全系数计算公方七理论上只要＞1，就可保证正常情况下摩擦提升机无滑动安全运行，实际设计时常取前防滑字命系数o》1．25静防
Multi-rope friction hoist transmission principle has always been based on the European technical transmission principle formula, shown in Figure 1, that is, T1 = T2eμαT1 for the heavy side of the rope tension and T2 is the light load side of the rope tension. Anti-slip safety factor calculation Gongfang seven theory as long as> 1, you can ensure that under normal circumstances friction hoist non-slip safe operation, the actual design often take the former non-slip life coefficient o "static 1.25
