This powerful low tare weight 40,000lb class rig is suited to large diameter "wash" drill holes as well as deep wire line cored "exploration" holes. The rig is mounted on a low tare weight all wheel drive carrier with high flotation low ground pressure tyres.
Tool boxes - large tool box under deck, tool box mounted on deck behind right side of cab
Feed system (patented) cylinder feed through gear track design. Pullback 40,000lbs. Pull-down 18,000lbs. Travel speed up 0 to 300'/min. Down 0 to 261'/min. Drill feed 29'/min.
Derrick, 10"x16" tubular Derrick construction with 40' overall length, 26' top head travel 55,000lbs rating (no Derrick crown load).
Transfer case single output, full power transfer case road / PTO shift from truck cab.
Hydraulics mounted on 2 hole gear box, truck engine / transfer case powered feed, winch, auxilliary and set-up functions are powered by 2 axial piston load sense pumps. Rotation is a closed loop circuit powered by a variable displacement piston pump. Cooling hydraulic oil cooler mounted on deck.
Feed system (patented) hydraulic cylinder / sliding gear track design, provides tremendous power (40,000lbs pullback), requiring less maintenance than conventional system with chains and sprockets or cables and sheaves.
Top head drive A variable 2-speed / torque, floating head provides smooth operation and helps the operator recognise specific formations while drilling. Top head hydraulically slides to the side, (off hole) for convenience of setting casing up to Range 2 length (34', 10.36m). Top head rotation 2 motor combination (2 option) planetary / spur gear 4 speeds / torques 0 to 172 rpm, 52,000 ft lbs torque 0 to 230 rpm, 39,000 ft lbs. torque or 0 to 221 rpm, 4,379 ft lbs. torque 0 to 500 rpm, 1,938 ft lbs torque
Split centraliser table centraliser base plate is split in half, rear half retracts hydraulically, and the front half swings out to accommodate casing and tools. Also includes an air-operated drill pipe holding wrench and hydraulic breakout wrench.
Controls left hand mounted, functionally grouped gauges and controls with twin fold-up platforms.
Drill Force was established in early 2008, by a small group of motivated, working investors who were disappointed with the deteriorating skills and equipment levels then commercially available in New Zealand.
