CGR-174U

Umbilical Compaction Grouting & Rotary Drill Rig

The CGR-174U is a powerful mini drill rig designed for small drilling job sites. This compact grout casing installation drill rig has an umbilical system that allows the machine to get into tight places, by been connected by hoses to a 74hp tier 4 engine and to a hydraulic tank.

The umbilical hydraulic power unit enables the drill rig to be the smallest possible size while still having a lot of power.

The CGR-174U drill rig comes with a mud and water pump for wet drilling and also has a 4 speed gearbox drill head with a built-in wet swivel.
