Ram is an outstanding mediumweight track drill far superior to any other track drill used for development or production work in mining, quarrying, or on construction projects. No other track drill is bigger or heavier, more rugged, more reliable, better performing, more productive, or more versatile than Ram. Ram is the high performance, low maintenance track drill. It is designed, engineered, and manufactured to be the best track drill on the market.

Ram operates with economy and dependability because its design has been refined over ten years of tough field service, under the best conditions and under the worst conditions.

Engineered for Endurance

     Operating economy and dependability demand endurance on the job, month after month. In a track drill, endurance comes from strong, well-designed components that add extra weight and strength for tough day-after-day working conditions. Ram is one of the heaviest track drills in its class, and it's all working weight. Low profile construction, longer and wider tracks, and extra weight give Ram excellent stability and balance, in tramming and settling up. The Ram chassis provides a rock-steady drilling platform for increased hole production, economy of operation, and total availability.
    Ram is built for tough, punishing work and has the stamina to withstand extremes of climate and 'round-the-clock operation. Chassis components are better protected against damage than on any other rig. Air, hydraulic, and lubrication systems are designed for severe service, with practically no maintenance.

Low Profile Design for Stability and Balance

    Extra weight and low profile construction work together to give Ram ground-hugging capabilities not found in comparable rigs. Its low center of gravity and wide-track stance provide superior stability and balance in all tramming and drilling attitudes. Side-hill, Ram Highperformance Track Drill Illustration

rocky-rough terrain is easily negotiated by Ram with its 10" wide crawler pads and nearly 1500 square inches of ground contact. For symmetry and better balance, the boom pedestal is located near the center line of the chassis and the pivor point of the main boom arm is midpoint between the tracks. In addition to providing better balance, this design improves the range of over-track drilling positions on both sides of the machine for reaching hard-to-get holes in tight palces.

Equalizer Bar

Ram utilizies a unique mechanical oscillation device mounted to each side frame which allows the tracks to adjust independently to uneven terrain. Because it is purely mechanical, no adjustments are ever required and maintenance consists only of occasional greasing. Total oscillation of 15° between tracks compensates easily for boulders and outcroppings when tramming over rough terrain. Independent track oscillation provides solid ground contact when setting up to drill in any terrain.

High Performance Tramming Motors ram highperformance track drill illustration

Ram is equipped with two independently operated 11-1/2 hp Pistonair tramming motors - almost double the tramming power of most other drills. These heavy-duty, high torque air motors provide more than ample power for towing a big portable compressor, climbing steep side hills, and for quick and easy moves between drill holes. Oversized spring-loaded, air-released automatic brakes are standard equipment for operating safety. The brakes will hold Ram in any position it can negotiate under its own power. Brakes and transmission gearing are enclosed in an oil tight case, fully protected against rock dust and weather.

Durable Track Construction

Track side frames are built to withstand the extremes of hard usage for the life of the machine. Heavy steel plate rock guards extened the full length of the crawler frame to provide strength and rigidity and are well shrouded to prevent rocks from jamming the tracks. Five bottom idler rollers give solid support to each track and distribute the load evenly. Ten inch wide crawler pads and forged steel tread links assure firm footing for vertical or inclined drilling in uphill, downhill or sidehill positions. Sprockets are solid steel construction for strength and added weight. Even the drive sprocket pillow block is of reinforced steel construction and uses bolt-on mounting for easy field replacement, if ever necessary.

Track Adjustment

A unique track take-up device consisting of a grease operated single acting cylinder and coil spring is built into each side frame. Adding grease pressurizes the cylinder, compresses the spring, and keeps the tracks tight. Vent releases excess pressure and cover prevents tampering, or overgreasing.
