The invention relates to earth-moving equipment with continuous action intended for surface mining. A rotary trench excavator with telescopic boom has an undercarriage, mounting frames, pylons, unloading conveyor. The telescopic boom of executive device is installed on the rotary platform with possibility of change of radius of action of excavator at its operation, and on the telescopic boom of the executive device a telescopic device with system of automated belt tension is installed, this can change the length of transportation of face conveyor. The technical result is in the development of rotary excavator design with variable digging radius, decrease of number of conveyors. |
