SINGLE-ROPE AERIAL TRAMWAY FOR LUMP LOADS Russian patent published in 2006 - IPC B61B7/00 

FIELD: mining industry.

SUBSTANCE: invention relates to single-rope aerial tramways for transportation of large lump loads, mainly, overburden rock to quarry spoil bank. According to invention, in proposed single-rope aerial tramway for lamp loads, each carrying device is made in form of hook-like load-carrying member with stiffening ribs from outer side. Arc-shaped suspension is used with hinge joint in middle part orientated square to pull-and-carry rope. Upper part of suspension is made with form of support member with insert. Load-carrying member is provided with roller in lower part installed for rotation in horizontal plane and engaging with horizontal bar located in zone of charging device, and spatial discharge bar found before drive sheave. End face edges of each load-carrying member are made narrowing upwards are profiled in plan to arcs of circumference. Carrying devices are arranged on pull-and-carry rope close to each other. Support sheaves provided with wedge grooves are orientated in vertical plane. Walls of grooves form angle with vertical less than friction angle at interaction with pull-and-carry rope free zone under them. Additional support sheaves orientated in horizontal plane are installed along contour of pull-and-carry rope for interaction with rope, being installed on supports for rotation. Drive, tension and horizontally orientated support sheaves are provided with horizontal flanges to support pull-and-carry rope.

EFFECT: provision of higher capacity of single-rope aerial tramway for lump loads.
