HAMMERHEAD MOLE TOOLS
HydroGuide ® winches are
designed to facilitate
extraction of burst heads
through manholes to
reduce the need for
expensive receiving pits.
New product is attached
to the pneumatic pipe
bursting tool and is
pulled into place as the
tool follows and bursts
the existing line.
Excavation costs can be
reduced on projects from
6" (15 cm) to 12" (30 cm)
(size on size or one
upsize) by utilizing the
manhole exit method.*
The HydroGuide HG12 winch has a patent-pending self-deploying downrigger.
The new HG12 puts advanced design to practical use. No more heavy lifting or
positioning of cumbersome pieces in constricted manholes — the boom is
conveniently raised and lowered by hydraulics and extends to the required length.
The HG12 winch is designed to maximize efficiency and minimize setup time and
effort for pipe bursting, slip lining, pipe pulling, cable pulling, and swage lining.
Setup and teardown can be done in minutes, not hours. The bottom line is less labor
and potentially more profit. The solid, dual capstan design offers constant pulling
force over the entire cable length and helps reduce cable wear. Remote control and
a powerful downhole light put the operator in better control of the burst process.
*Manhole exiting is a patented process of Earth Tool Company LLC, US PATENT 6,299,382 B1.
HammerHead Pneumatic Bursting
System — Engineered for Sewer
Replacement of 6" (15 cm) to 30" (76 cm)
Pipe bursting employs high-powered piercing tools with special bursting
heads to fracture old service lines while pulling in new replacement lines,
and it can be done without affecting expensive surface structures.
HammerHead Mole bursting heads can be removed at the end of the line,
allowing the piercing tool to return to the entrance pit through the new
service line. Because it eliminates an exit pit, excavation costs are cut in
half. Pipe bursting is easy on adjacent utilities because it follows the existing
pipe path and requires a minimum of excavation. This allows you to work in
congested areas without hampering normal traffic flow.
