The Astec® EarthPro™ Series DD3238 offers contractors the power and features of a much larger unit with the mobility and flexibility to fit onto any jobsite in any environment.
The DD3238 provides 32,000 lbs of thrust/pullback force with the capability of up to 3,800 ft-lbs of rotary torque. The maximum rotary speed can reach up to 225 rpm. The drill weighs 20,000 lbs., and is 247 inches long by 89 inches wide. The DD3238 is powered by a 125-horsepower John Deere turbocharged diesel engine. It also has an onboard FMC mud pump that can pump up to 47 gallons per minute at up to 1500 psi. This new drill also boasts the field-proven dual rack-and-pinion carriage drive that has made American Augers’ maxi-rig drills the market leaders. The floating carriage is capable of two speeds, including a 120 ft/min fast mode for adding and removing rods.
The DD3238 uses 10-foot drill stem and can carry up to 500 feet of pipe. The powered pipe greaser and state-of-the-art rod loader are standard features, as are the floating open-top vise wrenches.
The ergonomic operator’s station includes a microprocessor-controlled electronic readout for all the function gauges. The LCD screen is backlit and has function key operation for quick and easy view of all critical drill functions. It also offers both a drill mode and machine diagnostic screen for quick and easy information gathering. The multi-function single joystick controls all drill functions, and the comfortable, adjustable seat helps combat operator fatigue.
In addition, the DD3238 offers independent rear stabilizers, and a single-drive stake down system that can put down up to four stakes if necessary, and offers optional rock augers. It has a tethered travel control unit to help operator visibility during tramming and transport, and the improved front-drive track system offers traction and balance. The patented Es!Lok system is integrated into the drill controls, and there is an additional strike alert system with a voltage sensor for added safety.
The sleek new look and style of the DD3238 comes through with the new front and rear hood design that allows easy, ground level access to the engine and hydraulic systems. The drill’s mud pump is also covered by the rear hood for added protection and curb appeal.
