Winch boom designed to aid in reversible pipe bursting operations provides extra clearance in the manhole or exit pit to allow for removal of the pipe bursting expander during reversible bursting projects.
The boom’s enclosed sheave configuration provides optimum winch cable alignment, the company says. The boom also features adjustable bracing legs. 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.
