ABSTRACT:
A machine for drilling holes in the deck of a flat bed or other type trailer. The machine has a cross beam and rails for a wheeled carriage supporting a drill press for drilling holes in the deck in an X-direction across the deck. The cross beam and rails are carried upon wheeled trucks which are moveable longitudinally along the length of the deck in a Y-direction. The counteract thrust and to anchor the machine, adjustable clamps are provided at opposite ends of the cross beam which bear against the underside or other suitable fastening point of the trailer. The cross beam ties the machine together in providing support for the wheeled carriage, the rails, wheeled trucks and the clamps to provide a rugged and easily maneuverable machine for moving a drill press in any desired X-Y direction.
