Abstract

A light device for trenchless replacement of pipes includes a pipe parting mole, a length of cable that is engagable to the mole, a cable pulling device and a cable pulling device engagement frame that provides a mounting structure for the cable pulling device. The cable pulling device engagement frame generally includes a reaction plate and an annulus member for removably engaging the cable pulling device with the frame. The device is configured for sideways engagement of the cable within the frame and the annulus member. Two pairs of cable engagement collets may be utilized; a first pair being disposed within the cable pulling device to engage the cable on a pulling stroke, and a second pair may be disposed within the frame or the cable pulling device to engage the cable on a recovery stroke.
