The GBM 240A is the industry-leading pilot tube system for accurately guiding horizontal auger bore equipment. With hundreds of systems being used globally, industry leaders rely on the accuracy and versatility that the 240A adds to their trenchless toolbox.

Features:
Establish line and grade accuracy critical for gravity flow installations.
Adjustable base frame adapter fits all major auger bore machines.
Minimize project cost by reduced casing diameter requirements.
Achieve longer auger bore installations with straight alignments.
Utilize as a stand-alone system in a 10-ft shaft to direct install product pipe up to 24in OD.

GBM 240A JACKING FRAME

he 308A and 339A GBM systems are ideal pilot tube systems for the direct installation of sewer and water infrastructure when space is limited. These latching style frames are designed for pilot tube microtunneling while decreasing social, environmental, and economic costs associated with other installation methods.

Features:
Minimize launch shaft requirements.
Direct install 1m long product pipe using Akkerman Powered Cutter or Reaming Heads.
Extendable base frame options for longer pipe.
Utilize in round or box shaft configurations.
Versatile GBM system can be used for several Pilot Tube applications
Hi-flow hydraulic valving with PCH controls standard.
Works with all existing Akkerman Dual Wall Pilot Tubes.
Ideal GBM system for manhole-to-manhole sewer applications.

GBM 308A & 339A JACKING FRAME

he Rock Boring Unit (RBU) makes it possible to use any manufacturer’s auger boring equipment to install a range of common diameter steel casing pipe in high compressive geology. The RBU features 6.5‐in. disc cutters, muck scrapers, a high capacity main bearing, and water‐jetting to advance pipe through rigorous ground conditions. The RBU performs well in rock and varying challenging ground conditions.

Water‐jetting actively cools the cutter head tooling

Features:
Use any auger boring machine to install 24‐48‐in. steel casing
Robust design with high capacity thrust load disc cutters to fracture rock into cuttings aggressively
Cutter head rock scrapers assist in transferring cuttings away from the face to the inlet cavity, to the lead auger for removal


ROCK BORING UNITS

The 4800 Series GBM system is designed as an all-in-one system excelling in all pilot tube installation methods including auger boring, pilot tube microtunneling, and rock boring.

Features:
No diesel emissions in working shaft.
Direct install final product pipe or casing bore with one system.
Minimize launch shaft requirements.
Configurable latching style base frames to accommodate long pipe joints.
Two-speed hydraulics and gearbox travel system expedite pilot tube installation.
Hi-flow hydraulic valving with PCH controls standard.
Works with all existing Akkerman Dual Wall Pilot Tubes.
Installs pilot tubes in a wide range of ground conditions including rock.
