Abstract: A center hole ram can have a barrel, and a piston that is moveable relative to the barrel. The piston can define an axial hole that extends through the piston. A gripping assembly can be attached to the ram. The gripping assembly can be configured to grip a cable and pull the cable through the axial hole in response to multiple actuating strokes of the ram. Also, a bursting head can be attached to a cable. The cable can be pulled through a tunnel (such as an existing pipe) and through a piston of a ram. Pulling the cable can result in the cable pulling the bursting head through the tunnel toward the ram. Also, pulling the cable can include gripping the cable with a gripping assembly attached to the ram, and actuating the ram.

Abstract translation: 一个中心孔冲头可以有一个筒体，一个可以相对于机筒移动的活塞。 活塞可以限定延伸穿过活塞的轴向孔。 夹紧组件可以连接到压头上。 夹持组件可以构造成响应于冲头的多个致动冲程而夹紧电缆并且拉动电缆穿过轴向孔。 此外，爆破头可以连接到电缆。 电缆可以通过隧道（例如现有的管道）和通过活塞的活塞拉出。 拉电缆可能导致电缆将破裂头通过隧道拉向冲头。 此外，拉动电缆可以包括用附接到压头的夹紧组件夹紧电缆并且致动冲头。

Abstract: Cable pulling systems and methods of use are provided suitable for trenchless cable pulling applications, including bursting head applications for laying down replacement pipe underground. A chassis is provided that accommodates laterally disposed piston assemblies, both single cylinder and dual cylinder closed path piston assemblies. Also provided are quick release manifolds for cable holding grippers and cable pulling grippers for use with both single cylinder and dual cylinder piston assemblies. A chassis and cable pulling system also are provided for trenchless pipe extraction applications and which accommodate closed path piston assemblies. Small and large pipe diameter bursting head devices also are provided with integrated cable gripping and release assemblies. Also provided are methods for sealing cable ends.
