<p>PROBLEM TO BE SOLVED: To provide a hanging device with a tractor, which is driven by oil pressure suitable for a middle-scale transmission line route and is easy to handle, high in reliability and inexpensive. SOLUTION: An oil pressure generating unit 2 is suspended vertically through an engaging pin at all times, at the bottom of the frame 1 of a hand pulling style of a device and the device is equipped with a hydraulic motor 6 which is coupled via a coupling pin 14 in front of the frame 1 and rotates by the pressure oil from the oil pressure generating unit 2, a drive wheel 4 which is driven to press a transmission line C from under, being directly coupled with the hydraulic motor 6, and a press roller 5 which presses the transmission line C from above freely of adjustment of load, corresponding to the drive wheel 4.</p> |
