Elevating Positioners The sketch shows three different welds made on a spoolshaped work-piece by one <strong>Koike</strong> Aronson Geared Elevation Positioner. In the first step (A), the table rotates as a girth weld is completed at a constant operator height. Then in (B) the operator tilts the table up 45 degrees and completes a fillet weld on the rotating table at a specific height. In Step (C) the Positioner’s height is increased, then the table is tilted down to the 135 degree position and a final fillet weld is added while the table rotates. Due to low working heights, makeshift operator platforms are eliminated, creating much safer working conditions. <strong>Koike</strong> Aronson / Ransome Elevating Positioners are available in both Multiple post / Rack and pinion lift and ball screw elevation design. Both tilt, and rotational torque requirements are calculated in the same manner as Gear Driven Positioners (page 12). The elevation stroke should be derived from the required swing radius (diameter) that the work piece requires. Elevation components for both models are sized by the factory to correspond with the required load/size Elevating Positioner selected. Step “A” Step “B” GE500VF, Rack and Pinion Elevation rated at 50,000 Lbs. Capacity Step “C” 15 250PE, Screw Jack Elevation rated at 25,000 Lbs
