The exit pit of a horizontal directional drilling operation is a particularly hazardous location.
JT100 All Terrain Directional Drill
It’s serious business when you need a rock-drilling machine as big as the JT100 All Terrain directional drill, so you expect some serious power. The JT100 All Terrain delivers, with 100,000 lb (445 kN) of pullback supported by a monstrous, 268-hp (200-kW) engine. All of this earth-shaking power requires some serious stability, which is why the JT100 All Terrain directional drill is equipped with an exclusive dual-pivot drill frame. Of course, everything is engineered to maximize the productivity of the machine’s patented All Terrain technology, a two-pipe drilling system that enables you to drill and steer simultaneously.
Industry-exclusive, patented two-pipe drilling system provides more power to the bit than any other rock-drilling system in its class. The inner pipe works as a mechanical motor that drives the bit during the bore; the outer pipe thrusts the bit forward, steers the drill shaft and works to transmit full machine torque during the backream.
All Terrain is the only proven technology that enables simultaneous drilling and steering through rock and hard soil conditions, low drilling fluid volume means less waste, less cleanup and less environmental impact.
With its infinitely variable rotary drive, the JT100 All Terrain is the only rock drill in its class that can truly match exact spindle speed and torque to power through infinitely varying ground formations.
The JT100 All Terrain offers the optional pipebox loader device designed to transfer drill pipe from one box to another—and add or remove the upper pipe box—without the need for additional support equipment, so the pipe box is never empty.
JT100's 260-hp (194-kW) Cummins® engine delivers raw power more efficiently to all machine functions so the installation can be completed faster. The 268-hp (200-kW) Tier 3 Duetz® engine is available in less regulated countries.
With 100,000 lb (445 kN) of pullback and 12,000 ft·lb (16270 N·m) of torque, the JT100 is the ideal HDD unit for long bores, such as river crossings, and installations of large-diameter pipe.
With its infinitely variable rotary drive, the JT100 is the only drill in its class that can truly match spindle speed and torque, enabling it to power through virtually any soil condition.
The exclusive Ditch Witch heavy-duty anchor system eliminates the need for large and expensive support equipment, reducing transportation costs, setup time, and jobsite size.
The JT100 is the only drill in its class that enables the transfer of drill pipe from one box to another—and add or remove the upper pipe box—without additional support equipment, so the pipe box is never empty.
Large-capacity, 230-gpm (870 l/min) fluid pump plus larger hoses and fittings help move fluid downhole faster, for greater productivity; special damping feature reduces the downhole shockloads associated with greater fluid flow.
Ditch Witch designs and manufactures the long-lasting All Terrain drill pipe compatible with the AT100. Ditch Witch drill pipe provides the most return on your investment—each piece is inspected and gauged to ensure quality and reliability bore after bore.
Exclusive dual-pivot drill frame allows for steeper entry angles without raising the tracks off the ground, for outstanding machine stability and greater operator comfort.
Heavy-duty, double rack-and-pinion thrust drive is field-proven to push through the longest, toughest bores.
By providing the operator better control when making pipe connections, the exclusive coordinated makeup feature automatically adjusts carriage thrust speed when making up and breaking out drill pipe, minimizing wear on pipe threads and extending the life of the drill pipe.
Efficient hydraulic cooling system requires significantly less hydraulic fluid than competitors' models, reduces maintenance costs and keeps the engine operating efficiently throughout the workday.
Daily maintenance points can be easily accessed from one side of the machine resulting in more uptime each day.
Fully enclosed tinted window cab features instrument panel gauges that are positioned for visibility and conveniently placed controls.
Excellent view of the tool joint when making up and breaking out pipe; open-top vise wrenches are angled toward the operator.
Full color LCD display provides easy to understand engine diagnostics and informational messages which allows operators to stay informed on machine performance.
New extreme comfort operator’s seat improves overall comfort for the long days on the jobsite.
