GBM 240A Jacking Frame

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.
Avoid tripping augers to survey alignment and adjust for deviations during standard boring.
Probe for obstructions or detail changing ground conditions along the alignment.
Utilize for trenchless installations such as guided pipe ramming, guided reaming, probing, pipe roofing, foundation securing, geothermal, etc.
Use as a stand‑alone system in a 10‑ft shaft to direct install product pipe up to 24 in OD.
Installs pilot tubes in a wide range of ground conditions including rock.
