The GT300 Rotary Rig is a track based mobile platform designed for undertaking dynamic sampling and rotary drilling on extreme slopes such as dams or motorway and railway embankments. The working platform and drilling mast are automatically levelled in both planes to allow safe working on side slopes and steep inclines. The steel tracks, fitted with single grouser pads, achieve good ground penetration to give maximum grip on steep slopes up to 45 degrees. A 7500kg (8.25 ton) winch is fitted for added security on criticial sites.

The GT300 has radio control for travelling, winch operation and platform levelling override. Once in posistion the fold down walkways and drilling mast are deployed to give a secure level working area. All working areas are fitted with heavy-duty, GRP floor grating and guarded with removable handrails, kickboards and stanchions.
