Around the world, water well rig owners and operators appreciate the Atlas Copco T2W truck-mounted drilling rig for its application versatility, high productivity and ability to get in and out of even the most rugged conditions.
12-rod carousel with backloading capability from a 12-rod box
With applications such as geothermal loop field drilling in mind, the Series III carousel capacity was bumped up to 12 rods. Together with a rig-mounted rod box, which carries another 12 sticks of 3.5-inch rod, total depth capacity is 480 feet without having to bring a pipe trailer to crowded jobsites. The carousel itself is a swing in/swing out type. During transport the carousel folds over the derrick to lie balanced over the truck’s center line for improved road handling. The carousel has backload capability during operation, so it allows easy single-person operation, depending on the situation. Since the carousel brings pipe to the top head, the top head only has to travel in one direction to clear the way for handling pipe with the main hoist, auxiliary hoist or sand reel. Consequently, this gives operators the utmost confidence of perfect alignment every time they bring the top head back to center against a positive stop.
One option is a gear-driven head constructed with oversized gears, shafts and bearings for large torque applications. The other is a smaller, more compact hydraulic vane-driven head for lower torque operation. Both are three-speed designs.
T2W owners who experience its wide-open workspace and uncluttered deck offered by its tubular derrick prefer it over lattice-style derricks, especially during large-hole work and case welding. Though lighter in weight than traditional lattice derricks, the tubular tower provides superior strength and resistance to linear and torsional deﬂection and accommodates casing hammer, dual wall or drill and drive systems.
The single-cylinder cable feed system’s major components have been engineered to be larger and more mechanically efficient, reducing maintenance and part fatigue.
The cable feed is contained within the derrick, which protects its moving components from exposure to the typical drilling environment and rod handling operations.
An optional 15,000-pound winch with two-part line matches the pullback of the rig. This allows the operator to trip out of the hole with the winch or the head.
Optional hydraulic front drive assist turns the rig into all-wheel-drive vehicle.
An automatic transmission provides reduced fuel consumption, simplified operation and training, and better shifting performance in conditions such as freshly plowed or sloppy fields.
An optional 550 horsepower engine is available. A split-shaft PTO drive system selects drill or drive mode.
