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.

A pipe replacement system, comprising:
- a cable pulling system;
- a pipe breaking tool coupled to a cable, the pipe breaking tool having a diameter larger than the cable;
- a cable guide frame coupled to the cable pulling system, the cable guide frame including a lateral reaction plate and a vertical reaction plate;
- a plurality of guide pulleys attached to the cable guide frame, wherein the plurality of guide pulleys are positioned to define a common arc between a pipe to be replaced and the cable pulling system, wherein the plurality of guide pulleys include metal pulleys with a polymeric coating;
- and
- an opening in the lateral reaction plate;
- wherein the pipe replacement system allows passage of the pipe breaking tool past the lateral reaction plate and over the plurality of guide pulleys during use.
