Abstract: There is a radio control aerial automatic carrying system for carrying an object such as cut woods by a carrying apparatus suspended to a cableway. This system comprises: an aerial main cableway suspended in a desired felling region; drive wheels suspended to the aerial main cableway; outer casings coupled to the drive wheels; a power source disposed in the outer casings; hoisting apparatuses which are driven by the power source and hoist the cables to hang up and down the object to be carried; a receiver, provided for the outer casings, for receiving the radio waves transmitted from a transmitter and for generating control commands to drive the power source and hoisting apparatuses in response to the radio waves received; a rotary shaft which is attached to the outer casings and rotated by the power source; sub cableways suspended in parallel with the aerial main cableway; and two drive wheels, attached to the rotary shaft, for moving the carrying apparatus by operating the sub cableways.
