Grundomat 75P Spec Sheet

This Allied Pneumatic Hole Hog Missile rental requires a 185 CFM air compressor.

Used for horizontal bore jobs. Allied underground piercing underground boring and pipe pushing/pulling missle tools are the most efficient, least expensive method for underground pipe or service placement in construction and installation work. Pneumatic Hole Hog missiles open clean, compacted, self contained tunnels for pipes, cables, conduits, 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 or callbacks for settling backfilled trenches. Hole Hogs break through the ground while horizontal boring under roads, driveways sidewalks, parking lots, runways, foundations, or virtually any obstacle. Also known as a pneumatic gopher or under driveway boring machine. Unit has a 40' hose on it. Can get approx. 35' of underground run out of unit. Used for trenchless boring.

FAQ

When should I choose this 3" pneumatic mole instead of trenching or directional drilling?

This is commonly used for: installing conduit under concrete sidewalks; running water or irrigation lines under paved driveways; passing electrical cables under manicured lawns; and short utility crossings under roads without cutting asphalt. It is ideal for straight, short runs up to 35 to 50 feet where open trenching would destroy expensive paving or landscaping. For longer distances, deep utility runs, or paths requiring steering around obstacles, a directional boring rig or standard trenching equipment is required.

What kind of air compressor is required to run this burrowing mole?

This tool requires a heavy-duty 185 CFM tow-behind air compressor to supply adequate volume and operating pressure. Standard shop compressors or small portable electric and gas compressors cannot deliver the airflow needed to drive the internal hammer. If you do not have an air compressor meeting the requirements, Gap Power rents Air Compressor, Tow Behind, 185 CFM, 120 PSI Max that will supply the neccessary CFM.

How far can this tool bore underground, and what pipe sizes does it accommodate?

The mole creates a 3-inch compacted tunnel and typically handles underground shots of roughly 35 feet, with an absolute maximum reach around 50 feet in favorable soil. The resulting 3-inch bore is sized for pulling or pushing small utilities, irrigation pipes, gas lines, or electrical conduit up to approximately 2 inches in diameter.

What site preparation and pit excavation are needed before starting a bore?

You must dig a launch pit on the starting side and an exit or reception pit at the target end. The launch pit must be long and wide enough to position the 54-inch tool, line up your sights, and provide at least several feet of ground cover above the tool to avoid surface heaving. Always call 811 to locate and mark all existing underground utilities before digging entry pits or launching.

How do I transport the mole and its required support gear?

The mole itself weighs 72 pounds and measures 54 inches long, making it easy to carry with two people and transport in the bed of a pickup truck, van, or large SUV. However, remember to factor in towing capability if you are also renting a 185 CFM tow-behind compressor, which requires a standard hitch ball. Gap Power also offers delivery of the mole and the air compressor, if needed, directly to your jobsite.
