Pneumatic
Hole-Hogs open clean, compacted, self-contained tunnels for pipe, cable,
conduit or wiring at the lowest cost per foot.
Hole-Hogs eliminate
the need to break pavement or disturb landscaping from trenching or open
cuts. There's no reason to disrupt traffic by tearing up and
restoring asphalt or concrete.
And forget about
call backs for settling backfilled trenches. That's because
Hole-Hogs break through the ground while going UNDER roads, driveways,
sidewalks, parking lots, runways, foundations or virtually any obstacle.
Hole-Hogs have
quickly become essential tools of the trade for an ever-growing segment
of the construction industry. Hole-Hogs are used by gas, electric
and telephone companies and contractors. Cable TV companies find
Hole-Hogs very effective for running their smaller diameter services.
Water and sewer contractors like Hole-Hogs for their ease and accuracy
when placing pipe. Hole-Hogs also simplify life for trenching,
excavating, plumbing and heating workers, as well as pipeline, boring
and landscape contractors. Water supply services, municipal and
industrial plant maintenance departments regularly count on Hole-Hogs to
provide swift cost effective installation of service lines.
EXPERIENCE,
ENGINEERING, AND SIMPLICITY
Allied pioneered
and developed the concept of pneumatic underground piercing tools over
20 years ago. Today, through our continuous process of engineering
refinements, Allied provides the construction industry with
American-made, premium quality tools that simply do the job better.
Hole-Hog's greatest
design asset is simplicity. The rugged outer body is a
one-piece unit machined from heat-treated, high-alloy steel. There
are no welds or moveable nose pieces to wear, loosen or crack when
overstressed. Hole-Hog's design permits more efficient air
utilization inside the tool. That's why Hole-Hog offers faster,
more accurate penetration and greater productivity and durability than
other underground piercing tools.
Hole-Hog's
length-to-diameter ratio and one-piece body combine to provide a
high-energy, rapid percussion cycle that drives the tool straighter and
minimizes any chance of deflection. Allied's simple design of the
Hole-Hog incorporates only one moving part, the striker, that's driven
against a hardened, heat treated anvil. This yields more powerful
efficient performance, greater uptime and less maintenance.
BETTER BY
DESIGN, GREATER UPTIME
Design features
incorporated into Allied Hole-Hogs translate into simplicity in
operation and maximum uptime. And uptime equals profit for the
user. The Hole-Hog's one-piece body, matched with a unique air valve,
insures efficient utilization of air flow in the tool. This yields
a more controllable starting frequency and faster ground penetration.
The spring-back air valve insures the valve stem is not exposed when the
tool is idle. This protects the valve stem from being bent,
minimizing maintenance costs. A quick-change, whip hose is
available for all Hole-Hogs. For routing service, end cap flats
make Hole-Hogs easy to disassemble. Threaded anvils are available
on the "TH" series of Hole-Hogs for adapting nose accessories.
Hole-Hogs also feature a critically machined and hardened, one-piece
striker design to maximize air utilization without the need and
maintenance expense of replaceable wear rings.
ALLIED'S
PATENTED REVERSE MECHANISM
Hole-Hogs are
easily reversed with their patented, quarter-turn reverse mechanism
features. Many other underground piercing tools are difficult or
impossible to reverse. Allied's positive-locking quarter turn
reverse not only permits easy change of direction, but will not
"slip" unexpectedly into reverse. This patented reverse
mechanism makes Hole-Hogs even more versatile. Simply shut off the
air, twist the unit's whip hose one-quarter turn (90 degrees) and
restart the air supply. Blind shots, tie-backs, dead end holes,
even shafts for well casings are possible Hole-Hog applications.
OPERATIONAL
AND PERFORMANCE ABC'S
Allied's Hole-Hogs
require minimal labor and equipment - one to two men and an air
compressor. After locating existing underground service lines and
obstacles, dig a small entry pit on one side of the run.
Next, determine the depth of entry, line direction, location, route for
your service line, and grade of your shot. Start the Hole-Hog
slowly at first to insure proper direction, then increase the air flow
and speed as the unit sets its course. Aim the Hole-Hog
straight into the face of the entry pit (a sight gauge or marker at the
exit point can help aim the unit), then make the shot. It's that
simple.
When the shot is
completed, disconnect the air compressor hose from the Hole-Hog hose and
attach it to the service line (cable, pipe conduit, etc.) Draw the air
hose back through the tunnel, bringing the service line with it - ready
for hook up.
Hole-Hog's
tremendous punching power will move through compressible soil at up to
four feet per minute and will easily break through such obstacles as
small rocks and tree roots. Hole-Hogs work best in compressible
soil. Minimum depth of operation varies according to soil
conditions, length of the bore to be made and Hole-Hog model used.
