A floor-mounted forging press has a static piston arranged on the top beam and a cylinder which slides on the piston and forms a toolholder, and a bore extending through the piston for supplying pressure medium to the cylinder. The piston is hollow and is swivelly mounted by means of ball cups at the lower end of the piston and on the top beam and a thrust bearing member between the ball cups, the piston being held in the vertical position on the top beam with the aid of retaining means. One form of retaining means is a partially resilient pressure medium pipe which holds the piston. Alternatively pins, mounted by means of spherical surfaces, suspend the piston by way of a flange on the piston and are resiliently biased to hold the piston against the top beam in a free-play, resilient and freely movable manner, a bore being provided through the ball cups and thrust bearing member.

A hydraulic drop forging press has a prestressed frame comprising vertical columns and crossheads. A stationary piston is mounted on an upper crosshead and the press tool is carried by a moving cylinder. The cylinder is guided in a stationary upper guide mounted in the intermediate crosshead, and lower guides on the cylinder are guided on the columns.
