The MP-HD is a heavy-duty, all-hydraulic drill rig specifically designed for deep hole coring and RC drilling applications.
What separates the MP-HD?
Drill Head offers "Best of Both Worlds" for high-torque needed for augering and high RPM needed for coring, making it the preeminent multipurpose drill rig.
14 ft. [4.26 m] Drill Head Stroke.
40,000 lbs. [178 kN] of Thrust / Pull.
Various options and configurations.

Feed –

14 ft. [4.25 m] stroke and capable of 40,000 pounds [178 kN] upward thrust and 40,000 pounds [178 kN] pull down.

Drill Head - 

4-5/8" [117.6 mm] spindle bore, accepts all rod and casing sizes up to "P" wireline or "H" casing.  Eight infinitely variable speeds in forward and reverse. Hydraulically operated "slide type" drill head provides clearance for tool handling.  Drill Head speeds are from zero to maximum rpm in each gear range.

3rd Gear (0-450 RPM @ 980 ft./lbs. torque)

4th Gear (0-775 RPM @ 570 ft./lbs. torque)

Hi-Range -

1st Gear (0-196 RPM @ 2,250 ft./lbs. torque)

2nd Gear (0-400 RPM @ 1,080 ft./lbs. torque)

3rd Gear (0-760 RPM @ 580 ft./lbs. torque)

4th Gear (0-1,400 RPM @ 340 ft./lbs. torque)

Lubrication System -

Provides lubricating oil to drill head and transmission internal parts for extended bearing life.

Mast -

Welded structural steel supports and guides the rotation and feed components. Hydraulically positioned then rigidly held in position for drilling (from 45° to 90°), hydraulically lowered to the travel position for moving from hole to hole.  Also includes a crown block with sheaves.

Mast Dump -

A 5 ft. [1.52 m] hydraulic cylinder allows for convenient mast positioning when drilling angle holes or on uneven terrain.

Drill Frame -

Welded structural steel, supports the mast, control panel, winches and Cathead.

Dual Action Slide Base –

Provides both side-to side "wiggle-tail" and in-and-out movement of the drill unit assembly for precise positioning over the hole.  Side-to-Side not available on skid-mounted rigs.

Auger Guide -

Prevents "kick out" when starting new holes.  Available in multiple sizes to match preferred auger size.  Customer to specify.

Control Panel -

All controls and gauges are grouped together in a convenient panel located at the left rear of the machine and facing the rear.

Hydraulic Leveling Jacks –

Two (2) front and (2) rear mounted jacks with 4" [101.6 mm] bore.  36" [91 cm] stroke and lock check valves.  Jacks not available on skid-mounted rigs.
