Drill rigs - TMB 20

The fully hydraulic TMB 20 crawler drill rig has been developed as a down the hole hammer drill rig for small and medium-sized quarries and drilling companies. This rig is designed for dill-hole diameters from 92-127 mm and for drill-hole depths up to 25 m.

The TMB 20 is a fully hydraulic crawler drill rig with a rigid boom featuring 360º rotation (Option), a carriage with revolver magazine, a powerful down the hole hammer and dust collector. The undercarriage consists of a frame with crawlers, the corresponding components and bodywork. The drill is powered by a diesel engine via hydraulic motors and wheel hub drives.
