C6 Core Drilling Rig

The C6 Coring Rig is the result of a collaboration between seasoned field personnel and our own technical design team which includes Australian and German consultants.

FORWARD’S  C6 is a compact crawler mounted rig with all the user friendly functions drillers are looking for and all at their fingertips.. The rigs are built under  strict quality control protocols and are rigorously tested before dispatch.
 
The C6 has been built with reliability in mind and is assembled using only the very best first-world components such as Sauer Danfoss pumps and PVG valves, Danfoss and Eaton hydraulic motors, Manuli Hoses and Cummins engines.
 
The C6 is extremely compact but has depth capabilities that are only found on much larger rigs. AND, it drives straight into a shipping container which makes it extremely economical to ship anywhere in the world.
 
With safety in mind, the C6 has all the features that you’d expect in a modern rig such as safety guards and emergency stop buttons on all corners of the rig, fire extinguishers and optional automatic Co2 fire suppression.
