ABSTRACT:
A device for repairing the foundation of a building comprising a base frame being defined by a front end and a rear end. The front end and rear end are supported by wheels. A plate member is transversely mounted upon the base frame proximately near the rear end. A crane assembly is supported by the plate member. The crane assembly further comprises a three hundred sixty degree swivel joint mounted upon the plate member, a vertically extending shaft being swivelly connected to the swivel joint, a horizontally extending arm being mounted on the top of the shaft, and a lifting mechanism connected to the arm such that the arm can be lowered and raised. A fifth wheel assembly is situated underneath the base frame and is pivotally connected to the wheels supporting the rear end. A steering mechanism is connected to the fifth wheel assembly for maneuvering the direction of the rear wheels. A drive stand is swivelly connected to the arm at its far end. The drive stand is adapted to contain a foundation pier assembly. The present invention further comprises a means for driving the foundation pier assembly underneath the foundation to a point of resistance and a means for lifting the installed foundation assembly such that foundation can be elevated to a particular height. At least one stabilizer is removably attached to a corner of the base frame such that the weight of the base frame can be stabilized during the pier pressing process.
