CPT Soil Investigation Drill Rigs

TMG Manufacturing designs and produces an impressive line of compact track mounted CPT test drill rigs. Our CPT drill rigs, with front-mounted mast give you the ability to tilt the mast back for travel.

TMG has redesigned the rod clamping system, allowing you to choose from the standard top push system or TMG’s unique hydraulic clamp system.

This compact and powerful CPT test drill rig comes with an standard dual-hydraulic cylinder mast with anchoring drive head.
