This Patriot P1 is a used vertical drill — sometimes referred to as a drill rig or foundation drill — designed to bore large-diameter holes into the ground for applications such as foundation piers, caissons, and geotechnical installations. Patriot builds purpose-built drilling equipment for the construction and geotechnical industries, and the P1 is configured as a truck-mounted rig on a 6×4 chassis.
The carrier is a 2023 Freightliner M2-106 (VIN: 1FVHCYFEXPHNR2521), powered by a Cummins L9 engine (S/N: ). The drill itself carries serial number 1091222 (formerly 1081022) and is dated 2022. The drill drive is powered by a CAT C4.4 engine rated at 188 HP, which supplies the hydraulic system and all drilling functions.
The rotary drive produces a maximum torque of 50,000 ft/lbs with a crowd force of 25,000 lbs — the two primary performance figures that determine the rig's ability to penetrate hard or cohesive soils. The kelly bar system is a three-section round interlocking type: Bar 1 measures 10¾ inches with a 3/8-inch wall thickness, Bar 2 measures 7⅝ inches with a 1/2-inch wall, and Bar 3 measures 5½ inches with a 1/2-inch wall, terminating in a 4-inch stub with hole. This configuration allows the drill to reach a maximum depth of 35 feet at a maximum borehole diameter of 8 feet. Drill rotation runs between 12 and 73 RPM, with a spin-off speed of 120 RPM.
The main winch is a Dinamic Oil unit rated at 18,000 lbs with a line speed of 160 feet per minute. An auxiliary Dinamic Oil winch is also fitted, rated at 8,000 lbs. The slide assembly provides 32 inches of rear slide-off travel. The mast is a sectional design with three available height configurations and is delivered at a 25-foot operational height; it accommodates a tilt of 10 degrees for angled drilling applications.
The hydraulic tank holds 95 gallons and the fuel tank holds 65 gallons. Axle weight distribution is 15,042 lbs on the front and 33,239 lbs on the rear. The rig is finished in RAL 9005 Jet Black on the body and slide base, RAL 9016 Traffic White on the mast, and RAL 7015 Slate Grey as an additional accent color. The unit is located in Florida, USA, and is listed at $743,125.
