Abstract
Abstract There is a radio control aerial automatic carrying system for carrying an object by a carrying apparatus suspended to a cableway. This system comprises: an aerial main cableway for suspending the carrying apparatus; running wheels suspended to the aerial main cableway; an outer casing coupled with the running wheels and formed by a hollow body; a power source and a hydraulic apparatus which are attached to the outer casing; hoisting cables which are wound and driven by the power source; a receiver, attached to the outer casing, for receiving radio waves which are transmitted from a transmitter and for generating control commands to drive the power source, hydraulic apparatus, and hoisting cables in response to the radio waves received; two rotary shafts attached to the outer casing and rotated by the power source; sub cableways, suspended in parallel with the aerial main cableway, for supporting the carrying apparatus; and drive wheels, attached to the rotary shafts, for moving the carrying apparatus by operating the sub cableways. The frictions between the drive wheels and the sub cableways are enlarged, so that the slip of the carrying apparatus is prevented. The outer casing is also used as the operating oil tank and fuel oil tank. The structure of the carrying apparatus is simplified and reduced in size and weight.
