Boyles C8C core drilling rig

Atlas Copco Exploration Products
Boyles C8C core drilling rig
Technical specification
A powerful rig with high-altitude capacity
Reliable and powerful
The Boyles C8C surface core drilling rig is part of the Boyles
range, a new generation of Atlas Copco quality drilling rigs
that combine productivity with a favorable life cycle cost.
The crawler mounted Boyles C8C is the most powerful rig in
the Boyles range and yet easy to operate.
The Boyles C8C is equipped with:
Safe and ergonomic
• A powerful main hoist.
• A rod holder with a long-life gas cartridge that handles
rods from BO to PO size and casing up to PW.
• A proven and reliable rotation unit with 4-speed gear box
that can generate the high rates of penetration with very
high torque when it is required.
• Drill operators are protected from the rotation unit by a
safety cage.
• A reliable power unit, Cummins QSB 6.7 Tier III (179 kW),
which brings out the full capacity of the rig, resulting in
higher penetration rates to the bottom of the hole.
• Possible to operate by feel while focusing on the drilling
operation, thanks to the operator friendly control panel.
Radio remote controlled
• Three E stops on the drill unit are standard.
Favorable high-altitude capability
• The rig maintains its power at high altitude without the
need for a high-altitude kit.
• The whole hydraulic system is optimized to reduce the
effects of low air pressure in high altitude regions.
The tramming functions of the rig can be precisely controlled
from a safe distance, eliminating the danger of being on or
next to the machine while in motion. If radio contact is lost,
tramming will stop automatically.
Specifications
Main hoist
Hydraulic system
The powerful main hoist, equipped
with a hydraulic motor and a dual
brake system, ensures a well-controlled speed. The dual brake system
offers both dyna­mic and static breaking. When the lifting opera­
tion is
stopped, firm self-locking is applied.
Single line capacity
Bare drum: 133 kN (30 000 lb)
Line speed
Bare drum: 40 m/min (131 ft/min)
Cable size
29 m (95 ft) x 21 mm (0.83 in)
Wireline hoist
The wireline hoist adapts the level
wind angle to the drilling angle.
Level wind is adjustable to different
cable diameter.

Rotation unit
The rotation unit can handle BO-PO
rods and BW-HW casings. It consists
of a hydrau­lic motor, a sealed gearbox, a hollow spindle and an Atlas
Copco patented hydraulic chuck,
and quick change chuck jaws. The
rotation speed is adjustable from
the control panel.

The rod holder is hydraulically
opened and closed by gas pressure.
In case of loss of hydraulic pressure,
the rod holder closes instantly. The
gas pressure can be conveniently
monitored.
