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.
