Drill rigs - TMB 25

The fully hydraulic TMB 25 crawler drill rig has been developed as a down the hole hammer drill rig for medium-sized and big quarries and drilling companies. This rig is designed for drill-hole diameters from 92-130 mm and for drill-hole depths up to 32 m.

The TMB 25 is a fully hydraulic crawler drill rig with a telescopic boom featuring 270º 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 and a comfortable FOPS-ROPS cabin. The drill is powered by a diesel engine via hydraulic motors and wheel hub drives.
