ABSTRACT:
A machine for simultaneously augering and thrusting an anchor into the ground for later attachment of a utility pole or road sign. A vehicle is used to transport the thruster machine with a hydraulic control system such that a rail track is moved into thrusting position and locked in place. A winch, plus a system of hydraulic pistons will raise and lower an auger and thrusting device into the position desired. With an anchor affixed to the bottom of a platform, the auger is then used to drill out the dirt and other material so that the anchor may be more easily inserted into the ground. The thrusting process is facilitated by an indexing feature contained within the platform. A series of hydraulic pistons drive the anchor into the ground until fully stroked, whereupon the platform is re-indexed as needed to completely sink the anchor. Furthermore, a counter-thrust device may also be employed to stabilize the vehicle during the thrusting operation. Upon completion of the thrusting process, the platform is disengaged from the anchor and raised to its starting position. The rail track is then lowered back onto the flatbed truck, and the vehicle can then be driven to the next desired location for sinking an anchor.
