Abstract: Tool support apparatus having a frame mounted on wheels and motors for driving the wheels to move the frame. A ram tube carrying different tools at its lower end supported in a cylinder mounted on an oscillator bracket which cooperates with an oscillator slide carriage slidably mounted on shafts supported on the frame and a hydraulic cylinder mounted on the frame for moving the oscillator slide carriage along the shafts. An electric motor for moving the lower end of the ram tube in a first arcuate direction and another electric motor for moving the lower end of the ram tube in a second arcuate direction in a plane perpendicular to the plane of movement in the first arcuate direction. A hydraulic cylinder attached to the ram tube for moving it vertically.
