ABSTRACT:
A mobile foxhole excavator (MFE) is mounted on a standard military vehicle for transport and positioning. The excavator is powered by a self-contained internal combustion engine, which powers a hydraulic system for positioning an auger mast in three mutually perpendicular planes (horizontal, vertical and lateral) to permit the auger to bore holes at any desired angle between vertical, downward, and horizontal, as well as boring at various overhead angles between horizontal and near vertical. A single hydraulic motor is used to operate the boring auger, as well as various hydraulic cylinders to effect the desired positioning of the auger mast.
