Ditch Witch JT3020

Features
We could say that the JT3020 Mach 1 is the strong, silent type, but there's nothing cliche about a mere 80 dBA coming out of a 156-hp (116-kW) turbocharged diesel engine. We could also say that the operator's station is a driller's dream, that the fluid pump is a long-wearing workhorse, and that it's got the best rack in the business. But don't take our word for it. With the JT3020 Mach 1 and All Terrain, drilling is believing.

General Information

An extended range directional drilling unit producing 70, 000 lb (311 kN) of thrust and pullback, and 210 rpm of spindle speed. Surface-launched bore is tracked with Subsite® Electronics tracker and a beacon in the downhole tool. Drilling unit can pull back multiple conduits in a variety of soil conditions.

Operating weight includes drilling unit with 24 unlined drill pipe, pipeloader, onboard crane and anchoring system

Engine

Must have Deutz model BF6M1013ECP (turbocharged and aftercooled) engine or equivalent and produce 265 hp (198 kW) of intermittent power. Must be contained in the drilling unit.

Hydraulic System

Must have separate hydraulic pumps for pipe rotation and thrust so that both functions receive optimum flow at all times. Must have three independent hydraulic systems to perform all onboard functions. Must have hydrostatic rotation, thrust, pullback, and drilling fluid, and open gear pumps for all other functions.

Ground Drive

Must offer rubber or steel tracks for easy mobility on varied ground conditions. Track direction must be controlled with single handle control located in operator's station. Speed must be controlled with incremental throttle controls located both in the operator's station and at the setup console.

Operator Station

Primary operator station must be located inside multi-position cab that pivots from ground drive position into drilling position. Cab must offer optional heat and air conditioning for year-round comfort. Must have adjustable seat. Must have integrated remote display and electric strike system control panels. Must have thrust, rotation, and drilling fluid pressure gauges. Must have single lever to control track, thrust/pullback and rotation movement. This single lever must also contain a quick fill switch for the drilling fluid pump and the two speed carriage travel switch. Must use sealed rocker switches. Must have switch-operated drill pipe breakout and pipeloading controls. Must have all controls within easy reach during operation.

Setup console must include levels to ensure proper leveling of unit during setup.

Strike System

Drilling unit must come equipped with an electric strike system. The strike system must be active when the key is in the on position and must indicate an electric strike through current and voltage sensing. Must have capability to store electric strikes in the processor to record strike history. Must include a warning strobe on the drilling unit. Unit must come with standard traffic cones and tape for barricading the jobsite and must come with a certificate for three pairs of 20 kV boots and gloves.

Drilling Fluid System

Flow rating of onboard drilling fluid pump should be at least 200 gpm (757 L/min). Fluid pressure and flow must be controllable from the operator station. Fluid pump must be mounted on the drilling unit. Antifreeze tank must be mounted on drilling unit.

Optional fluid systems and mixing systems must also be available. These systems must be adaptable to high volume needs and integrate with the drilling unit's on-board fluid pump to deliver plenty of pressure and flow.

Drilling Unit Requirements

The drilling unit must provide a tracker control mode that allows tracker operator to disable hydraulics to thrust/pullback and rotation before downhole tools are changed. It must provide a visual indication to tracker operator that power has been interrupted. It must be integrated in tracker and allow mode to be overriden with a special tracker control key.

The drill pipe breakout system must be designed with vise-type wrenches for maximum torque and high performance. The wrenches must tilt toward the operator for full visibility of the tool joint during operation. The drill carriage must have a floating spindle which will also reduce thread wear on the drill pipe.

Two drill pipe boxes containing twelve drill pipe each must be mounted on the drill frame and must be capable of holding 24 joints or approximately 360 feet (110 m) of pipe. These boxes must be easily replaced with full boxes when the supply is exhausted.

360° rotating crane must be mounted on unit for changing drill pipe boxes, anchoring the unit, lifting downhole tools, and other jobsite needs. Crane must operate on an independent hydraulic motor for efficiency. Crane must be controlled by tethered control that functions only when operator is not in seat.

The anchoring system must allow two heavy-duty anchors for maximum stability. Must be able to disconnect drilling unit from anchor system to move drilling unit offsite without removing the anchors. Must have override function that will allow limited drive operation of disabled machine. Must have lightbased troubleshooting system to allow for easier diagnosis of a system failure.

The pipeloading device must be capable of processor-controlled functions. An automated drill pipe lubricator must come standard on each unit for increased drill pipe thread life.

Drill frame must pivot to allow setup at maximum angles while keeping tracks on the ground. Drilling unit must have independent front and rear stabilizers to aid in leveling drilling unit on side slopes.

Drilling unit must provide up to 210 rpm spindle speed and up to 10,000 ft LB (13 600 N · m) of torque. Must have variable speed rotation motor and pump for maximum rotation speed control. Must have motor and chain driven thrust to increase carriage speed and serviceability.

Drilling unit must have cruise control capability that allows operator to set thrust or pullback and rotation speeds and maintain those speeds hands-free. Cruise control function must allow speed adjustments made by operator touching a button. Cruise control function must also allow operator to resume cruise control by touching a button after a drill pipe connection is made.

Drilling unit must have Mach 1 electronics that control ground drive, pipeloader and drilling functions. Drilling unit must also provide a diagnostic system for technicians to use as an aid in troubleshooting.

Downhole Tools

Must have drill pipe 177 in (4.5 m) long and with 4.25 in (102 mm) diameter tool joints available. The drill pipe tubing must be at least 3.62 in (92 mm) in diameter. The drill pipe must be a composite expanded end tubing with 4140 steel tool joints for maximum flexibility and wear. The drill pipe bend radius must be a minimum of 230 ft (70 m).

The directional head must be capable of accepting a variety of fluid nozzles and cutting bits for varied soil conditions and accept a beacon that locates down to 100 ft (30 m).

Operator Training

An operator's manual which describes proper operation and maintenance of the product must accompany the product when it is shipped.

Hands-on operator training must be provided at no additional cost at time of delivery by authorized dealership personnel.

Delivery and Availability of Parts

The manufacturer must have a system in place that provides special "unit down" shipment and delivery of parts for emergency situations.

Location of Service Facility

To reduce costs of maintaining the product, there must be a full service facility located in a reasonably close geographic location to the customer's main facility.

Repair Guides

Complete repair guides must be available. Repair guides must include detailed repair procedures, maintenance procedures, specifications and safety information for all major components of the product.
