Abstract

A frame for heavy machines, particularly presses for extremely high pressures having the press tools mounted on vertically extending columns of the machine frame so that actuating of the press involves a horizontal relative movement of the tools, includes an upper beam, or yoke, which is movable into an open position by a movement comprised of an initial raising of the yoke out of force-transmitting engagement with the tops of the vertically extending frame columns and by a subsequent horizontal movement, preferably a swinging movement, into a position where the gap between the tools is accessible.
