The safe and smooth operation of cranes needs to improve the frictional behavior of the sliding parts of crane booms. For those sliding parts, in general, slide plates made of polymeric materials are used with the counter face of steels. This study therefore investigated the tribological characteristics of polymers as a slide plate under the conditions assuming practical machine application. As a result, 6 nylon and PTFE-added 6 nylon were found to provide the excellent durability and frictional characteristics for long-term use. hi particular, PTFE-added 6 nylon showed more stable frictional characteristics under severer frictional conditions. Further, the tribological characteristics of polymers were thought to be related with their elongation after fracture and its smaller values could result in the excellent durability and frictional characteristics.
