FIELD: opencast mining; applicable in muck transportation from deep horizons of open pits. SUBSTANCE: transportation complex includes guide cable tensioned between supports and vehicle connected with balloon by means of swivel installed on guide cable for free motion over it. Complex also has pulling cable winch, rollers and pulleys, loading and unloading points located on supporting stations. Complex is provided with additional track cables with supports installed on open pit surface and with additional points of loading located in points of intersection of haulage berms with horizontal projection of complex cable main line. Vehicle is connected with hoisting winch by means of cable stretched over deflector puller secured to balloon swivel. Value of balloon free load-lifting capacity equals weight of hauled load or somewhat lower. EFFECT: extended process potentialities of transportation complex due to use of balloon lift partially relieving load on cable system. 3 dwg
