FIELD: mining industry. ^ SUBSTANCE: device has moving portion with electric engine and pump machine, end section with cable drum, hydraulic-driven crane on rotary column with hydraulic boom and hook support. Corbel and bulldozer dump fixed on hydraulic boom and corbel by spreader bar and axes. Body of bulldozer dump is made in form of two curved metallic surfaces connected together, and its width equals distance between inner surfaces of caterpillar tracks. Cutting edge of dump body is placed, in edge position, along lower level of tracks with possible displacement in parallel to horizontal surface of mine during change of hydraulic boom position due to lever mechanism formed by spreader bar, corbel, bulldozer dump body and hydraulic boom. ^ EFFECT: preserved device efficiency in case of forming in mine soil of deep track from caterpillar tracks. ^ 4 dwg |
