The Big Beaver-One man portability with truck mounted power


Document Number: 1080

The new "Big Beaver" portable drilling rig features one man portability with its wheeled modular frame. Only 26" in width and 80" in height, the Big Beaver can be easily transported to just about any drilling site for precision augering of environmental test wells or under eaves of buildings for foundation repairs or even indoors. In extreme terrain conditions, the drill rig can be removed from its modular wheeled frame and mounted on a truck, trailer or crawler for transport to remote drill sites.

  • Allows one person to manually do any job that generally requires a truck mounted rig. Can be used indoors, in the field, or anywhere a truck can't go. The unit is narrow and short and can be pulled like a hand truck. 
  • Drills 6" diameter holes up to 100 feet or 16" diameter holes to 28 feet in typical applications. Holes can be augered up to 15 degrees from vertical. 
  • Complete system consists of a modular steel frame, 18 horsepower engine and three wheels.
  • The Power Source can be used to run other tools like power drills, concrete saws, breakers, tampers, chain saws or any hydraulic tool. 
  • If you already own the PS-16 Little Beaver engine, it can be used with the frame and wheels (the PS-16 is being replaced with the PS-18 engine to give more horsepower). 
  • Other auger sizes can be special ordered up to 16". Hollow stem augers can be ordered also.
