TT Technologies Introduces New Winch Boom
TT Technologies recently unveiled a new winch boom specially designed to aid in reversible pipe bursting operations.
The new boom provides extra clearance in the manhole or exit pit to allow for the easy removal of the pipe bursting expander during reversible bursting projects. The boom’s unique enclosed sheave configuration provides optimum winch cable alignment and helps facilitate the space saving design. The boom also features adjustable bracing legs for added stability.
During the reversible bursting process, a Grundocrack straight barrel tool, equipped with a front expander is placed into the host pipe at an entry pit or manhole. A constant tension Grundowinch guides it through the host pipe. The Grundocrack effectively hammers its way through the host pipe, displacing the fragments into the surrounding soil, while simultaneously pulling the new pipe. At the manhole, the front expander is disconnected and the tool is reversed through the newly installed pipe and removed. 630.851.8200, tttechnologies.com
