HBR 602 : powerful and lighter drilling rig for jet grouting
The new Hütte HBR 602 is a hydraulic drilling rig for jet grouting. Designed with a stroke lenght beetween 4700 mm and 5250 mm, it can create deep foundation elements with a max. jet grouting depht of 17,6 m / 17,5 m. The HBR 602 is one of the most compact and flexible rig for jet grouting and it has been manufactured also with increased power. Designed to be highly efficient, it has a ligher package and a poweful engine; thus it is suited for difficult drilling conditions in confined and limited areas, which require particularly compact, mobile and also powerful equipment.
Jet Grouting is applied when civil engineering works require soil improvement to build new structures or to restore the existing foundations. These techniques are employed in a wide range of cases such as underpinning of existing structures, diaphragm walls, structural and waterproof bottom plugs, tunnel consolidation, launch and arrival shafts for TBM and slope consolidations as well.
The HBR 602 has been engineered for jet grouting but it is also intended for many other drilling applications as it can be tailored to any costumer need or geological conditions.
