KEY FEATURES, JT100 ALL TERRAIN
|
- Industry-exclusive, patented two-pipe drilling system provides more power to the bit than any other rock-drilling system in its class.
- The JT100 All Terrain's 268-hp (200 kW) engine delivers more raw power more efficiently to all machine functions so the installation can be completed faster.
- Because big rigs see big downhole forces, machine stability is imperative; the JT100 All Terrain's exclusive dual-pivot drill frame allows the entry angles you need without compromising stability—or operator comfort—while drilling.
DETAILS, JT100 ALL TERRAIN
|
- With 100,000 lb (445 kN) of pullback and 12,000 ft·lb (16 270 N·m) of torque, the JT100 is the ideal directional drilling unit for extended-range bores and installations of large-diameter pipe.
- Optional onboard crane is designed to load and unload pipe boxes, anchor the unit, and handle drill pipe, reducing the need for additional support equipment.
- Fully enclosed cab features instrument panel gauges that are positioned for visibility, conveniently placed controls, and an excellent view of the tool joint.
- The JT100 All Terrain is the only rock drill in its class that enables the operator to transfer 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.
|
- By providing the operator better control when making pipe connections, the JT100 All Terrain's assisted makeup feature greatly extends the life of your drill pipe—one of your biggest downhole investments.
- With its infinitely variable rotary drive, the JT100 All Terrain is the only rock drill in its class that can truly match spindle speed and torque to find that "sweet spot" that will power through infinitely varying ground formations.
- The JT100 All Terrain's double rack-and-pinion thrust drive is field-proven and heavy-duty enough to push through—and pull you through—the long, tough bores.
- Large-capacity, 120-gpm (450 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.

ALL TERRAIN AIR HAMMER SYSTEM
- Equipped with the All Terrain Air Hammer, Ditch Witch All Terrain directional drills can penetrate rock of 20,000 to 35,000 psi and harder, where rotary units and mud motors lose effectiveness.
- Advanced technology enables the All Terrain Air Hammer to continuously drill as it is being steered, an exclusive All Terrain drill feature that results in superior productivity; other air hammers require stopping the drill rotation to change directions.
- Peak performance achieved with the Rockmaster Air Housing, which features larger air ports that help increase production.
- Ditch Witch All Terrain directional drills have standard cruise control that maintains thrust and rotation settings, which reduces operator effort and increases productivity.
- All Terrain Air Hammer requires no oiler or drilling mud, which reduces overall cost of production (severe cases may require a foaming agent in the water).
- Minimal cost of spoils cleanup: used properly, the All Terrain Air Hammer leaves only dry cuttings and a relatively small amount of foam used downhole to remove cuttings.
- A very low flow rate—4 gpm (15 L/min)—means low fluid costs.
- Complete kit includes the All Terrain Air Hammer plus:
- 6.5-inch (165 mm) convex bit with spherical inserts
- Convex bit jaw
- 4-inch (102 mm) jaw assembly
- 5-inch (127 mm) Rockmaster Air Housing
- Two slide pins
- Fluid pump/air adapter kit

DRILL PIPE REFERENCE
Ditch Witch drill pipe is specially manufactured to be the longest-lasting pipe in the horizontal directional drilling industry. But do you need lined or unlined pipe? What size of pipe thread? What length and bend radius? Our Drill Pipe Reference tool instantly gives you the answer to these questions and more. This information is also available on your mobile device. |
Jobsite safety cannot be overemphasized. You're working on and around heavy equipment that you need to understand and respect. Below is a "Safety Matters" topic relevant to this Ditch Witch product. For other "Safety Matters" topics, plus safety videos and other important facts about jobsite safety, please visit our Ditch Witch Safe page.
Locating safety. Remember that you can verify locates with Ditch Witch electronic pipe and cable locators, and a sure way to verify the location of buried utilities is to expose the lines with a Ditch Witch vacuum excavator.
|
 Safety Matters is intended to promote discussions of safety issues among underground construction professionals. TOPIC #2: ELECTRICAL STRIKE—USING A HORIZONTAL DIRECTIONAL DRILL Potential HazardsPrecautions- Call 811 to have underground utilities located prior to drilling. Also, contact other utilities that don't subscribe to 811.
- Verify locates using a reliable electronic locator.
- Any time you drill, the electric strike system must be properly set up, tested, and used.
- Note: The electric strike system does not detect proximity to an electric line. If the electrical strike alarm sounds, assume a strike has occurred.
- Wear electrically insulated gloves/boots.
- If crossing a known electric line, expose the line and watch the crossing while drilling and backreaming.
- Use a tracker to locate the drill string only when drilling has stopped.
What to DoIf a strike occurs: - If you are on the drilling unit, stay where you are
- Notify others to stay away.
- Have someone call electric company.
- Pullback the drill string to try to break contact with the line.
- Press the electric strike system reset/status button.
- Do not leave the unit until the electric company says it is safe to do so or until you have no lights or alarms on the electric strike system after pushing status button several times at least one minute apart.
- If you are off of the drilling unit, do not move or touch the unit or anything connected to the unit. If you must move to get help, take very small steps to shuffle away from drilling unit.
Information/Facts- Voltage is similar to pressure in a water hose.
- Current is similar to flow in a water hose.
- Electrical current kills by:
- Intense heat causing physical burns
- Stopping the heart and brain
- Tightening your muscles, causing you to lose muscle control and not be able to let go
- It takes very little current to cause physical harm:
- 20mA makes it difficult to breathe
- 20mA can paralyze muscles
- 50-200mA causes your heart to beat out of control
- 200mA makes your heart stop completely
- Some strikes produce smoke and can cause the ground to explode around the strike; however, some strikes give no indication at all.
- Electricity takes the path of least resistance. The steel drill string on a horizontal directional drill provides very little resistance, so electricity can easily flow from the drill head back to the drilling machine.
- Part of the flow of electricity will pass into the ground around the strike, so the ground may be electricuted.
- If all parts of your body are at the same voltage, current can't flow. Take, for example, a squirrel on an electric line. The voltage in its body is the same as long as it doesn't step off the wire or touch something that leads to ground. When it steps off, one part of its body is at one voltage and another part is at a different voltage. This voltage difference allows current to flow. This is known as "step potential."
- An electric strike system on a drill machine consists of:
- Voltage stake — this is to be located away from the machine. It detects the voltage difference between the ground stake and the drilling machine.
- Current transformer — detects current flowing through the drill string.
- Reset/status button — used to recheck the status if the alarm sounds.
- Self-test — the self-test should be done every time the machine is used.
- Alarm — if the alarm sounds, assume a strike has occurred.
- Strobe light — provides a visual alert that a strike has occurred.

JOB RELATED, JT100 ALL TERRAIN
Stay Cool And Stay Alive
If you work outdoors, summer is one of your busiest times of the year because it’s typically the driest season and offers the most hours of daylight. But the sun providing all that productive daylight can be the biggest jobsite hazard you face all year. Excessive heat can bring down anyone who doesn’t take the necessary precautions.Tier 4 Standards Begin In 2011 by ucononline.com The EPA's Tier 4 engine emission standards for off-road, diesel-powered equipment of 175 to 750 hp go into effect on Jan. 1, 2011. What does this mean for equipment manufacturers, dealers and customers? Planning Ahead For WinterWinterizing your equipment is a small investment of your time that is guaranteed to pay big dividends. Your operator’s manual provides details on proper care during winter, but here are five essential steps you should take.
stopimg title="keepCool_img1" style="padding-right: 20px;" align="left" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-RIGHT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: left" alt="keepCool_img1" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/1_KeepCool_260x195(1).jpg" border="0" />Catastrophic tornadoes and floods have grabbed recent headlines, but each year one weather phenomenon kills more people than tornadoes, floods, hurricanes, and lightning combined: heat.
According to the National Oceanic and Atmospheric Administration (NOAA), an average of more than 1,500 people in the U.S. die each year from excessive heat—yet it is the most preventable of weather-related deaths.
If you work in construction, summer is one of your busiest times of the year because it’s typically the driest season and offers the most hours of daylight. But the sun providing all that productive daylight can be the biggest jobsite hazard you face all year. No matter how tough you are or how used to the heat you think you are, excessive heat can bring down anyone who doesn’t take the necessary precautions.
The following information applies to anyone who is employed in an outdoor profession—construction workers in particular—but also applies to those who work in hot factories and anyone who spends time outdoors exercising, gardening, or laboring in any capacity during the summer months. (This is general information. More specific information can be found in the sources cited below.)
Know Your Chemistry
Our bodies dissipate heat by varying the rate and depth of blood circulation, and by expelling water through the skin and sweat glands. When we reach the danger zone, when our blood is heated above 98.6 degrees, we begin to pant—we’re literally “working like a dog.”
Sweating alone does little to cool the body, unless the sweat is removed by evaporation. But high relative humidity inhibits evaporation. When you’re checking the forecast for tomorrow, pay close attention to the heat index: the combination of relative humidity and air temperature. For example, if the air temperature is 96° F and the relative humidity is 65 percent, the heat index is 121° F. This is the heat your body really feels.
Heat disorders involve a reduction or collapse of our bodies’ ability to shed heat by circulatory changes and sweating, or a chemical (salt) imbalance caused by too much sweating. When heat gain exceeds the level the body can remove, or when the body cannot compensate for fluids and salt lost through perspiration, the temperature of the body's inner core begins to rise, bringing on various degrees of heat-related illnesses.
stopimg title="keepCool_img2" style="padding-left: 20px;" align="right" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-RIGHT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: right" alt="keepCool_img2" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/2_KeepCool_260x195.jpg" border="0" />Ranking Heat Disorders
The severity of heat disorders is relative to a person’s age, weight, fitness, medical condition, and degree of acclimatization to the heat. For example, heat cramps in a 17-year-old may translate as heat exhaustion in someone who is 40, and heat stroke in a person over 60. Common heat disorders include:
- Sunburn. Along with being painful and irritating, sunburn can significantly retard the skin’s ability to shed excess heat. The best solution for sunburn is prevention, by applying sunscreen throughout the day.
- Heat cramps. Symptoms are painful spasms, usually in the muscles of the legs and abdomen, often preceded by profuse sweating.
- Heat rash. Also known as prickly heat, heat rash can occur in hot, humid environments where sweat is not easily removed from the surface of the skin by evaporation. Serious heat rash can be so uncomfortable that it inhibits sleep and impedes a worker’s performance.
- Heat exhaustion. Symptoms include heavy sweating, weakness, headache, fainting, vomiting, and skin that is cold, pale and clammy. It is possible to have a normal temperature with heat exhaustion.
- Heat stroke or sunstroke. This is the most serious health problem for workers in hot environments. Heat stroke occurs when sweating stops and the body can no longer rid itself of excess heat. Symptoms include an excessively high body temperature (106° F or higher); mental confusion or delirium; convulsions; hot, dry skin; strong and rapid pulse; and possible unconsciousness. Make no mistake: heat stroke can be fatal, and victims need immediate medical attention.
Prevention: The Best Solution
The number one method of avoiding heat disorders: avoiding heat. But for construction workers in the summer, this is simply not possible. So, here are some tips for staying cool and staying alive, beginning with the most obvious:
- Drink plenty of fluids. Your body needs water to keep cool. Drink water even if you don't feel thirsty. Proper hydration actually begins the day before a long, strenuous day in the sun. Before increasing your fluid consumption, consult a physician if you (1) have epilepsy or heart, kidney, or liver disease; (2) are on a fluid-restrictive diet; or (3) have a problem with fluid retention.
- Do not drink alcoholic beverages. Alcohol dehydrates your body. Enough said.
- Limit caffeine intake.
- Do not take salt tablets unless specified by a physician.
- Put less fuel on your inner fires. Foods that are heavy in protein increase metabolic heat production and also increase water loss.
- Dress as lightly as possible. You need protective clothing, of course, but consider light-colored fabrics, such as cotton, that breathe.
- When possible, take longer breaks than normal in a cool, shaded area. A rested worker is a more productive worker.
- Know the symptoms of heat illnesses. Use a buddy system to keep tabs on your fellow workers.
- Acclimate yourself to the heat. You can “get used to” the heat, to some degree. Workers, especially those who follow the advice above, can eventually develop some degree of tolerance. However, new employees and workers returning from an absence of two weeks or more should have a five-day period of acclimatization: 50 percent of the normal workload and time exposure the first day, gradually building up to 100 percent on the fifth day.
stopimg title="keepCool_img3" style="padding-left: 20px;" align="right" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-LEFT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: left" alt="keepCool_img3" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/3_KeepCool_260x195.jpg" border="0" />Supervisor Obligations
There are precautions every employer should take when temperatures are high and the job involves physical work.
- Understand the signs of heat stress and permit workers to interrupt their work if they are extremely uncomfortable.
- Provide training about the hazards leading to heat stress and how to prevent them.
- If possible, schedule the heaviest workload for the coolest part of the day: early morning or late evening, when the sun is less intense.
- Make sure your workers have easy access to cool water—a minimum of one quart of water per hour, per worker.
- Schedule frequent rest periods with water breaks in shaded or air- conditioned areas.
- Routinely check on workers who are at risk of heat stress due to protective clothing and high temperature. Pay close attention to those who are at risk because of age and physical condition (including obesity and diabetes).
When A Fellow Worker Is Ill From The Heat
- Call a supervisor for help. If the supervisor is not available, call 911.
- Have someone stay with the worker until help arrives.
- Move the worker to a cooler/shaded area.
- Remove outer clothing.
- Fan and mist the worker with water; apply ice (ice bags or ice towels).
- Provide cool drinking water, if the worker is able to drink.

stopimg title="19a" style="padding-right: 20px;" align="left" alt="19a" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/19astopimg4Take the time to winterize your equipment this year. A few minutes spent could save you time and money in the months to come. The amount of winter care your equipment needs depends both on the climate and how it is used. Check your service manual guidelines, and keep the following tips in mind:
1. Check coolant. Provide protection by using the recommended antifreeze/water mixture for the lowest temperature expected during operations.
2. Change the oil and filter before cold weather arrives. In addition, use lubricants recommended for low temperature applications.
3. Maintain the battery. Remove cables, clean cable ends and posts, and clean and tighten terminals on the cranking motor. And remember never to charge a frozen battery.
4. Check tire inflation. Tires inflated in a warm shop will be under-inflated when used in cold temperatures.
5. Give hydraulic components time to warm up before beginning work. If you’re running diesel equipment, be sure to idle the engine a few minutes before shutting down to properly lubricate internal components. Your local Ditch Witch® service technicians can help you make the most of your cold-weather equipment productivity, and can suggest winterizing techniques that are perfectly suited to your operation.
