Note:  the presses were designed to be “Extra Heavy Duty” to accomplish 800 tons of force at 4” up from the bottom of the stroke (typical similar presses achieve maximum tonnage at approximately ¼” to ½” up) with special features including 500 HP main motors, extra wide press columns, 7-1/2” diameter tie rods and 19” wide hardened twin pinion gears (38” “ of total gear face width), with an eccentric hub welded as an integral part of the gear eliminating a keyed shaft.

The presses were manufactured in 1972 and have recently been rebuilt with all new bearings, bushings, trabon lubricating systems, front safety light curtains, Allen Bradley electrics and Allen Bradley programmable controls.  The 500 HP motors were rebuilt and rewound at that time.  The original cam operated “lift out” device was replaced with a new 4-cylinder hydraulic cushion. 

The presses have never been back into production after the rebuild was completed and they are in “Like New” condition.
