The USI-Clearing D4-1600-900-156-102 likewise appears to be a four-post straight-side press with a double-crank drive. The “D4” prefix indicates a double-action configuration: one main ram (inner slide) with 1,600 tons capacity and a second ram (blankholder slide) with 900 tons. In effect it can also operate as a single-action (combined-slide) 2,500-ton press in some modes. Functionally, it is classified as a high-tonnage mechanical (forging) press: a 4-point frame with independent primary and secondary slides (double-action) on a double-crank drive.
