SALT LAKE CITY — April 12, 2010 — Boart Longyear® Limited (ASX:BLY), the world’s leading
integrated drilling services and products provider, released the new flyable SC11 rig, the only
compact and modular rig in its class that offers 5456 Nm of torque and can manage PQ-size rods.
The drill is a surface exploration rig targeted at the 1300- to 1500-meter NQ market, and can be
broken down into compact flyable modules.
“The SC11 is built from Boart Longyear’s proven LM® technology and designed for use in surface
applications where access is limited and drill footprint is a critical consideration,” said Craig Mayman,
Boart Longyear global product manager for capital equipment. “It’s extremely flexible — conveniently
assembling and disassembling in flyable, compact modules — while delivering best-in-class power at
a cost-competitive value. And, in colder regions, its compact size enables operation inside a drill
shack.”
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 5456 Nm at the head for tri-cone drilling and a 1230-rpm speed for diamond drilling. Whether lowor
high-torque applications, the SC11 features high-efficiency hydraulics to easily make or break rod
joints and transport rods safely.
Hydraulic actuators also control the rig’s rod handler, providing smooth and efficient movement in
three dimensions. The rod handler utilizes proven LM rod-handling technology and features proximity
sensors to protect the operator by preventing rod drops when operators are nearby. A laser beam
system positioned between the helper and rod handler control panel stops movement when drillers
enter the operating area. Once the beam is interrupted, the rod handler immediately stops and can
only be restarted when the driller resets it.
In addition, the rig utilizes 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-toshift
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.
Pressed steel framing with male-female joints help the modules drop into position and highly visible
jacking and lifting points make assembly and disassembly safe and easy.
