Wire rope mis-wrap due to wire rope “cut-in” on LEBUS drums

Nihon Kikai Gakkai ronbunshu
The physical mechanism underlying wire rope cut-in in multilayer drums was experimentally investigated. Although the wire rope appears to be correctly spooled on the drum, hoisting the load can cut the spooling wire rope into multiple layers, leading to ...

Research of the Linkage Point Trajectory Curvature and Design of the Related Mechanism

Jixie chuandong, 2017
The linkage point trajectory curvature theory on the existing literature is summarized and improved. Another method determining the linkage point trajectory curvature center by the absolute and relative instantaneous center is working out.

Effect of torsional angle on the fretting wear behavior and fracture failure mechanism of steel wires with spiral contact structure

Journal of Materials Research and Technology
The fretting wear of steel wire will reduce the service life of wire rope and severely threaten the safety of mine hoisting. To investigate the influence of torsion on the fretting wear behavior of steel wire, the fretting wear tests of steel wires with ...

Simulation modelling of residual resource for hoisting mechanisms in the mining industry

IOP Conference Series: Earth and Environmental Science
Abstract The rationale for prolonging the operational life of the crane is rooted in the economic viability of conserving metal and energy, leading to ecological benefits. Cranes, being structures with a high metal content, contribute to pollution reduction by eliminating the necessity for additional manufacturing processes in mining ...
