TRACKED DRILLING SITE INVESTIGATION P60

The P60 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 winch is fitted for added security on critical sites.

The P60 has radio control for travelling, winch operation and platform levelling override. Once in position 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.

Safe operation and speed of deployment are major features of this rig. The P60 can be transported to site on a suitable 7.5T LGV and with a 3.4kph travel speed it can be quickly positioned on site.
