How to Size a Positioner How to select a gear driven positioner to best meet your needs The illustration below shows a typical capacity plate that we attach to each Aronson Gear Driven Positioner. This happens to be the capacity plate for a Model HD400 Aronson Gear Driven unit. An HD400 is designed to handle loads up to 40,000 lb (18,140 kg) with a CG at a distance from the surface of the table of 12 in (300 mm). All the information required for loading the positioner is either on the capacity plate, or it can be simply calculated from the data on the plate. Rotation Torque Load To find...

Other Factors to Consider Practical Center of Gravity as it Effects Gear Driven Positioners • CG of a weldment is exactly in the center of a symmetrical weldment. • ‘A’ is a symmetrical weldment: There is no top or bottom, just sides, the CG of a weldment is usually near the center of the weldment. • The ends and two sides of a 1 in steel plate. Each end is 1x12x12 and weighs 40.8#. Each side is 1x12x34, weighs 115.6#. 115.6# x 2, plus 40.8# x 2 equals 312.8#. (Steel weighs approximately .283 lb/cubic inch.) If one end is secured to the table of a Gear Driven Positioner, the CG will be 18...

Universal Balance Positioner Features • Machined Tables • Caster Bases Available • Manual Height Adjustment • Friction Lock Brakes • Powered rotation available Koike Aronson Ransome Universal Balance Positioners allow safe and quick manipulation of large, awkward work objects when it is critical to maintain an efficient down-hand welding position. A welder can position objects up to 4,000 lb by simply applying fingertip pressure and does not need to raise a helmet or break an arc. The Universal Balance principle is to intersect the rotational axis center of gravity with that of the tilt...

UBSeries Setup 1. Find Center of Gravity for Rotation. Koike Aronson universal balance positioners allow welders to maintain the most productive 10˚ downhand welding position. Workpiece should be placed on positioner with the center of gravity coinciding with the rotational axis of the table. Movement of the object around table rotational axis is almost effortless. In order to prevent over-travel of mounted objects, Koike Aronson has applied friction bands to the rotation point of the worktable which generates slight resistance and allows the load to be stopped at any desired point. 2....
