<p>PURPOSE:To facilitate a work to mount and demount a tractor to and from a cable run by dividing the tractor into a caterpillar portion for pulling an electric cable and a motor portion for driving a caterpillar. CONSTITUTION:A caterpillar tractor side is lifted to shift a runner bar 14 from the lower side of the runner bar 14 of a cable run to the middle between main bodies 1, 2, and a mounting hanger 15 is hooked on the bar 14. A butterfly nut 16 attached to the hunger 15 is fastened to fix the stationary side main body 1 to the bar 14. Next, the motor mounting hanger 18 of a motor 17 is hooked on the bar 14 and fixed with a butterfly nut 19. Subsequently, the drive shaft 24 of the caterpillar tractor is connected to the motor 17 by means of a one-touch coupling 12. In this manner, the tractor is mounted to the cable run but since the mounting of the caterpillar tractor and the motor is conducted separately, weight for one time is halved to improve operation efficiency. And the transport to a construction site is facilitated very much.</p> |
