Abstract: A cable puller and associated methods are shown. Useful example methods include pipe bursting using cable pullers as shown. Cable pullers and methods shown provide a mechanical advantage that increases an amount of cable pulled in one cycle. Selected examples are shown that include a pulley located on a distal end of a moving portion of an extending and contracting beam. The pulley and the mechanical advantage it supplies helps to improve the efficiency of the cable puller and reduce manufacturing cost of the cable puller.

Abstract: A pipe replacement system and method are shown. Configurations are shown that include a pulley that does not damage a bursting tool, as the bursting tool is pulled into a pit. Configurations are also shown that include a boom that does not need an extraction cage for the bursting tool.

Abstract: Pipe splitting apparatuses and systems including a replaceable blade, and methods therefor, are provided. In various examples, a cable retention and release mechanism is configured to releasably engage a cable and includes one or more segments of a pipe splitting apparatus including a cable passage. A segmented collet includes tapered segments and is disposed within a tapered portion of a cable passage of the one or more segments. Channel surfaces of the tapered segments together form a cable channel through the segmented collet. The cable channel is configured to widen in a disengaged position of the segmented collet and narrow in an engaged position of the segmented collet. A spring is disposed within the spring pocket of the one or more segments to bias the segmented collet distally in the engaged position.

Abstract: Pipe replacement devices, and systems are shown. Devices and systems may include jointed cutters and floating cutters to navigate difficult pipe replacement conditions. Devices and systems may also include replacement pipe with pre-installed supply hoses, such as lubricant supply and/or pneumatic supply hoses. Methods of pipe replacement are also described, including splitting old pipe and pulling in new pipe behind the equipment as splitting progresses.

Abstract: A pipe splitting assembly includes an articulating hammer nose assembly having a pipe splitting cutter and a rotatable joint coupled with the pipe splitting cutter. A pneumatic hammer is distal to the articulating hammer nose assembly, The pneumatic hammer is configured to drive the articulating hammer nose assembly proximally away from the pneumatic hammer. The rotatable joint is coupled between the pipe splitting cutter and the pneumatic hammer, and the articulating hammer nose assembly is rotatable into one or more angles relative to the pneumatic hammer through the rotatable joint. A cable coupling is interposed between the pneumatic hammer and the articulated hammer nose assembly. The cable coupling is configured to attach a cable to the pipe splitting assembly. The cable coupling and the rotatable joint are configured to transmit to the pipe splitting cutter a compression force from the cable coupling and dynamic percussive forces from the pneumatic hammer.

Abstract: Pipe splitting apparatuses and systems including a replaceable blade, and methods therefor, are provided. In various examples, a pipe splitting apparatus includes an outer surface including a recess. A blade including a portion is disposed within the recess. A hardenable material is disposed within the recess. The hardenable material is configured to flow upon application to fill empty space within the recess and at least partially around the portion of the blade disposed within the recess. The hardenable material is further configured to harden after application to secure the portion of the blade within the recess and fix the blade to the pipe splitting apparatus.

Abstract: A pipe replacement system and cable guide frame are shown. Configurations are shown that include plurality of guide pulleys attached to the cable guide frame to define a curved path between a pipe to be replaced and a cable pulling system. Configurations are shown where a pipe breaking tool is pulled over the plurality of guide pulleys for ease of removal after a replacement operation. Configurations are also shown that include a stationary splitter adjacent to the cable pulling system to prevent jamming of the cable pulling system.
