Astec EarthPro Geothermal Drill Rig Built To Harness The Earth’s Energy
The new Astec EarthPro Geothermal 4550 (truck-mounted) and 4550X (track-mounted) drill rigs are designed to meet the specialized demands of geothermal system installations.
Introduced by Astec Underground, state-of-the-art technology features make them ideally suited to high-production drilling applications, which include:
• Reliable Dual rack & pinion design
There are no chains, cables, or hydraulic cylinders to replace. All rack & pinion components are covered by a five-year warranty. The three-speed drive motors allow quick trip times with strong 45,000 pounds pull up and 22,000 pounds pull down. It provides safe, precise operation and features locking motors, which prevent carriage free falls.
• Automated Pipe Loader System
A single operator can drill and trip out up to 600 feet of pipe without winch assistance. Its pipe basket can hold up to 30 pieces of 20-foot pipe in 3.5, 4 or 4.5 inch diameter.
• Safe and Efficient Hydraulic Key/Vise Table Design
The distinctive table design features a vise breakout system on top for strength, versatility and safety. The key is located on the bottom for added safety and increases security for downhole tooling.
• Central Ergonomic Controls
Dual multi-function joystick controls are mounted on a console, which is adjustable for height and angle to reduce operator fatigue. The multi-function LCD display provides information on drill operation in easy-to-understand terms.
• Big Air
It carries a 1,050-cfm Sullair compressor with a maximum pressure of 350 psi to drill deeper and faster and to operate larger hammers.
• CAT Power
The drill is powered by a Caterpillar C15 ACERT turbocharged diesel Tier 3 Stage IIIA engine that develops 580 horsepower at 2,100 rpm and 1,953 foot-pounds of torque at 1,400 rpm. All filters, fluid checks, and fill points are located on the same side of the drill near ground level to make monitoring and maintenance quick and easy.
• Enhanced Maneuverability
A tethered two-speed ground drive system gives the operator better visibility when loading, unloading, and setting up over casing. CAT 315L tracks provide sure-footed traction and fast placement on the jobsite.
Optional equipment includes a water injection pump, mud pump, tool lubricator and tank, operator seat and a sand line winch. 865.408.2100, www.astecunderground.com
