WIPO Patent Application WO/2011/122811

A2

The present invention relates to a pulling device capable of laying and pulling 3-phase underground power cables and an automated pulling method using the device; and more specifically to a method for pulling 3-phase underground power cables at once by performing a cable pulling operation with the aid of an automation facility to reduce manpower and labor hours required for the work. To this end, there are provided a pulling device for 3-phase underground power cables and an automated pulling method using the device, the pulling device comprising: a first, second, and third drum mount, each functioning to fix three cable drums in a rotatable manner; a transmission means connected in such a manner that the first, second and third drum mounts rotate in the same direction at the same speed; a deceleration means connected to one of the first, second and third drum mounts to decelerate the rotational speed of the connected drum mount by applying a frictional force thereto; and a frame to which the first, second and third drum mounts are fixed.
