DM450 Water Well Drill Rig

The durable, mechanical controls neatly laid out on the robust, organized control panel includes engine monitoring, safety E-stop, hydraulic pressure gauges, friction control levers for mud pump and rotation circuits, and electronic throttle controls. Simple operation makes it easy to train new operators.

The top head carriage on the DM450 drill truck uses rollers instead of slides, creating quiet, smooth head travel with simple maintenance.

• long-lasting rollers are easily adjusted.
• rollers permit fast and safe top head travel.
• easy maintenance keeps rig performing like new.

Totally redesigned drillmast on the DM450 drill rig with 25,000-lbs of pullback, 15,000-lbs of crowd force along with 16-inch side shift of the 2-speed rotary drive with 4,600 ft-lb torque. The rigid drill mast design makes drilling straighter holes easier.

The 2-speed main winch motor on the DM450 provides full pull power when tripping out or with flip of a switch provides full speed, making travel time twice as fast. For job sites where support trucks won't fit on helper side, second jib swings and extends — in the other direction toward the driller's side —to pick up and place smaller objects.

• 2-speed winch motor on main jib for full pull power or full speed with simple flip of switch.
• main 12,000-lbf line pull jib swings and extends over helper's side. 
• second 1,800-lbf jib swings and extends over driller's side to cut time setting casing.

Mud pump options up to 5 ½ x 8 piston or series 4X3 centrifugal pumps and air compressor options up to 500/200 make this a strong compact unit. 

Using the helper side controls to operate the jib and winch functions controls, the helper loads the drill pipe in the single rod loader. This makes the DM450 easy to operate with a two-man crew.

The DM450 drill truck table assembly has clearance for 16-inch PVC casing. Easy access to table opening from control panel simplifies setting variety of casing sizes.

• remove bushings to set up-to 10-inch casing.
• remove center bushings and use control panel to retract table when setting 12-inch casing.
• remove bushings and use control panel to retract table then remove pin and swing open gate to make room for 16-inch casing.
   

Air-powered holding fork and hydraulically-operated, adjustable breakout wrench make tripping out fast and safe with the DM450 drill rig. The grease fittings on the fork help maintain mobility in freezing conditions. 

Available on a 450 HP Western Star 47X truck chassis to further simplify mobilization, the lightweight, compact drill rig is suited for large residential water wells, commercial geothermal, and cathodic protection drilling. Clean layout of the deck, complete with access panels, makes for easier maintenance of securely routed hydraulic hoses from above the rig.

INCREASED HORSEPOWER

Easily mobilize on tough terrain or up hills thanks to 450 HP Western Star 47X chassis with automatic transmission. Increased horsepower means more options, including series 4X3 centrifugal pumps and water transfer pump.

Create opportunity to task helper with other site chores or run a one-man job when you choose rod carousel option capable of backfeeding while running pipe. 

• simple, durable hydraulic fork at top of carousel operated from control panel holds drill pipe in position. 
• pod for each drill pipe contains a cushion spring prohibiting pipe from slamming into pod, protecting drill pipe and creating a quieter job site.
• mechanical alignment of top head with rods using indicator arrow and grooves on base eliminates need for electrical sensor that could malfunction.

Rod carousel options available to accommodate preferred drill pipe size:

• Carry 15, 3-inch pipes for a total of 300 feet with ability to backfeed carousel as running pipe.
• Carry 12, 3.5-inch pipes for a total of 240 feet with ability to backfeed carousel as running pipe. 
• Carry 10, 4.5-inch pipes for a total of 200 feet with ability to backfeed carousel as running pipe.

Factory-mounted Mudslayer^® 250 drilling mud cleaning system uses separate hydraulic circuit eliminating competition among functions, easily connects to pump for quick set up. Addition of the deck-mounted drilling mud cleaning system allows access closer to homes without hauling a mud pan behind the rig, eliminates shoveling out mud pans making job easier on drillers, and creates simpler job site cleanup.

Runs off of rig hydraulics, saving fuel compared to running an extra engine.

Bi-directional, hands-free pipe spinner system takes hands off drill pipe to quickly make and break joints with less wear on driller.

• switch on control panel dictates which direction wheels spin.
• single lever control engages both clamp and spinning function.
• innovative segmented rollers made of staggered, stacked plates with teeth to grab pipe increase performance, longevity, and ease of service.
• threaded fitting adjusts bumpers to optimize pipe spinner grip performance based on size of drill pipe used. 

Next Generation DMR6 Top Head on DM450

Engineers focused energy into improving the manufacturability, enhancing durability in the field, and simplifying serviceability of the DMR6 top head featured on the NEW Western Star chassis DM450.

Billet-Machined Gearbox provides improved strength, durability, and accuracy. The redesigned gearbox simplifies assembly as well as service in the field.

Higher Load Capacity Spindle and Pinion Shaft Bearings contribute to longer life in rough field conditions.

Splined Spindle significantly improves torque carrying capacity and longevity over keyways.

Redesigned Top Swivel

• easy packing seal adjustment can be completed in seconds with minimal tools
• improved seals and design prevent water ingression into the gearbox
