Abstract: A pipe breaking assembly is shown with a modular design that allows a user to more economically purchase a single base unit that is adaptable using a number of elements. Combinations of elements such as blade portions and expander cones, etc. allow the modular assembly to be tailored to a variety of job conditions. A pipe breaking assembly is shown that includes a particular configuration where a blade portion is located in front of a shortened expander cone. The shortened expander cone provides a lower contact area that in turn reduces friction.

Abstract: An improved cable pulling device and method is shown. The cable pulling device is smaller, less expensive, and easy to use for lateral line replacement. The cable pulling device includes a cable contacting portion that provides supplemental frictional force during a rotational pulling stroke. Among other advantages, this allows a smaller, more compact design that provides higher gripping and pulling power. Embodiments as described above further allow for a smooth jaw configuration that reduces cable damage. A cable pulling device is also shown that includes a configuration of a force distributing device. One embodiment includes substantially orthogonal plates that help to reduce device twisting during a pulling operation. In a further embodiment, a force distributing device is adapted for attachment to a ground working implement arm.
