架空索道的牵引钢绳在运转过程中反复地导绕、弯曲,不断地被货车抱索器夹持挤压(单线索道的牵引钢绳还直接承受货车作用的横向荷载),易于损坏。特别是钢绳的接头部分,它的有机芯被插入的金属绳股所取代,柔性降低,损坏就更快。钢绳损坏的表现有磨损、疲劳断丝以及接头处的绳股插头松动等。因此,必须对牵引钢绳进行经常性的检查和及时的修理。修理工作的本身又是一项繁重的体力劳动。在检修措施不合理或 Traction rope of the ropeway is repeatedly guided, bent and constantly squeezed by the truck gripper (the traction rope of the one-lane ropeway is also directly subjected to the lateral load of the truck) during operation, and is easily damaged. Especially the steel wire joint part, its movement is replaced by the inserted metal strands, the flexibility is reduced, the damage is even faster. The performance of the steel cord is damaged, fatigue, broken wires and joints at the rope plug loosening. Therefore, the traction rope must be regularly checked and repaired in time. Repair work itself is a heavy manual labor. In the unreasonable or overhaul measures
