Equipment profile

Built around the project configuration

The KLEMM KR 704-2E is a compact mains-electric vertical drilling rig for micropiles, underpinning, and high-pressure-injection work inside buildings and other confined sites. Its telescopic crawler retracts to 750 mm, while telescopic mast arrangements support drilling beneath approximately 2.2–3.5 m of headroom depending on rod or casing length.

The electrohydraulic drive removes local diesel exhaust from the working area and uses a 400 V, 125 A site connection. Mast, head, clamp, and HPI equipment remain configurable, allowing the rig to be planned around the site's access route, overhead clearance, and foundation method.
