2009 DF CAT COMPONENT DRILL RIG

The new excavator/ barge / Heli drill rig is designed for those tight sites with a low tare weight and can be configured from 1550mm down to 750mm wide. This rig can be  fitted with rubber tracks to minimize pavement damage. The mast height can be broken down so the height of the mast is only 3m. The rig is fitted with a main haul winch and a wireline winch which makes it an ideal little Geotech rig. This rig also has a separate power pack and is ideal for barge and helicopter drilling for Geotechnical investigations.
