1 Percussive Power for directional drilling assist Accessories Soil Removal Cone Conductor Barrel Ram casings through difficult soil conditions to more desira drill starting points. Tapered Locking Ram Cones Guide down-hole or mud motors to rocky soils through the conductor barrel. They allow one size GRUNDORAM tool to be adapted to fit many size casings. Used singularly, or in multiples, these cones provide a tight fit which helps deliver all of the GRUNDORAM s power to the casing. Provides friction-free section for product pullback. Overcome hydrolock with a pipe rammer. Rammer attached to product pipe during pullback. Percussive action keeps pipe moving and helps prevent high levels of pullback stress. PNEUMATIC PIPE RAMMING SYSTEM Adapts the GRUNDORAM to the pipe and provides an escape route for spoils. A sure start for your bore even in the worst soil. Pullback Assist GRUNDORAM for a complete ramming system Segmented Ram Cones These cones ensure a tight fit between the GRUNDORAM and the pipe as well as help minimize pipe flaring. They are especially useful for thin wall pipe in drives of less than 50 feet or when used in combination with soil removal cones. Adjusta Bearing Stand Heavy-duty stand provides support and alignment for the GRUNDORAM and casing in the start pit. Features an air bladder to easily raise assembly to correct grade. Percussive power frees immobilized product pipes. Pipe Removal Remove stuck product pipe and bore again. GRUNDOMUDD Bentonite Mixing & Delivery System Rammer attached to product pipe after pullback fails. GRUNDOMUDD porta bentonite mixing/delivery systems use a Venturi mixer/filtration system to quickly mix bentonite and water into slurry. An in-tank re-circulating valve prevents the mixture from settling. Percussive action pulls product pipe, removing it from the bore. POWER & PERFORMANCE The GRUNDOMUDD is availa in 225-, twin 225-, 500- and 1,000-gallon capacity models. All models are designed for use with pneumatic trenchless tools including GRUNDORAM pipe ramming. Salvage the job and bore again. Each self-contained unit comes complete and ready to use. A tank isolation valve allows pump lines to be cleaned without draining the tank(s). All models feature easy-to-clean round poly tanks. Drill Stem Recovery Retrieve stuck drill stems.

Advantages GRUNDORAM pipe ramming tools are ideal for the trenchless installation of steel pipe through a wide variety of soil types, without any rise or fall in the ground s surface. While some casing installation methods are impaired or even rendered inopera by rock- or boulder-filled soils, boulders and rocks as large as the casing itself are swallowed up during the pipe ramming process. Spoil is then removed after the installation is complete. Built for Power & Performance The Casing GRUNDORAM pipe ramming tools are manufactured from the highest quality steel alloys.

Mini-Atlas The Piston Versatile Tool The piston is subject to a large amount of stress and is designed to handle it. During manufacturing, the piston goes through a special heat treatment process that optimizes the strength and durability of the steel alloy and increases its resistance to corrosion. The piston is also fitted with Teflon seals. These seals help limit wear and fatigue, and help maximize ramming power by allowing the impact energy generated by the piston to transfer smoothly to the casing. In addition, the seals ensure that air consumption is optimized.
