Boyles C6/C6C core drilling rig
Technical specification
Flexible enough to take on almost any jobThe Boyles C6 surface core drilling rig is part of the Boyles range, a new generation of Atlas Copco quality drilling rigs that combine produc tivity with a favorable life cycle cost. Boyles C6 repre sents the most flexible rig size in the Boyles range and is available in trailer-mounted (Boyles C6) or crawler-mounted (Boyles C6C) versions.
Safe and ergonomic• Two E stops on the drill unit are standard and Boyles C6C
has another E stop for the Radio Remote Control.
• Drill operators are protected from the rotation unit by a safety cage.
• Possible to operate by feel while focusing on the drilling operation, thanks to the operator friendly control panel.
• Foldable 2-section mast simplifies short-distance transport of the rig.
Reliable and powerfulBoth the Boyles C6 and Boyles C6C are equipped with:
• 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 HW.
• 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.

Specifications
Main hoist
The powerful main hoist, equipped with a hydraulic motor and a dual brake system, ensures a well-con-trolled speed. The dual brake system offers both dyna mic and static break-ing. When the lifting operation is stopped, firm self-locking is applied.
Single line capacity Bare drum: 80 kN (18 000 lb)
Line speed Bare drum: 44 m/min (148 ft/min)
Cable size 27 m (89 ft) x 16 mm (10/16 in)
Wireline hoist
The wireline hoist has a high level of speed control to ensure safe and consistent opera tion.
The rotation unit can handle BO-PO rods and BW-HW casing. It consists of a hydraulic motor, a sealed gear-box, a hollow spindle and an Atlas Copco patented hydraulic chuck, and quick change chuck jaws. The rotation speed is adjustable from the control panel.
Power Hydraulic motor – variable speed/reversible
Final drive 4 in chain driven in oil bath – 2,5 ratio
Spindle (inner diameter) 117 mm (4 5/8 in)
