SALT LAKE CITY – A compact and modular drill rig offering 4,356 Nm of torque and managing PQ-sized rods is now available from Boart Longyear. The SC11 is an exploration rig suitable for users drilling 1,300 to 1,500-metre holes.
The SC11 delivers large-diameter and deep-hole drilling capacity with a 132 kN pullback rating and PQ handling capacity. The rig features a variable-speed motor that provides a low-end torque output of 5,456 Nm at the head for tri-cone drilling and a 1,230-rpm speed for diamond drilling. Whether low or high-torque applications, the SC11 features high-efficiency hydraulics to easily make or break rod joints and transport rods safely, according to the manufacturer.
In addition, the rig uses the patented Boart Longyear Nitro Chuck® with gas-charged springs that actuate the jaws holding the rods to provide fail-safe operation. The control panel also utilizes lift-to-shift rotation and feed levers to deliver constant speed and protect the operator against accidental actuation.
The SC11 has been designed to easily break down into flyable modules, with the heaviest lift being only 680 kg. Lifting points are easy to identify and are positioned at the module’s center of gravity to provide a balanced load, while quick-connect hydraulic couplings further accelerate assembly and disassembly and prevent oil spills. All modules utilize easy-to-see guides to help operators quickly align and assemble the rig, speeding up the landing process.
