Abstract: A press brake is comprised of a frame having a bed secured thereto with a ram displaceable to and away from the bed whereby to form metal sheets positioned on the bed. The ram is secured to a hydraulic piston through opposed symmetrical linkage assemblies. Each linkage assembly is connected adjacent opposed ends of the ram and includes a lever member pivotally secured to the frame by an anchor pin pivot connection. A link arm interconnects the lever member to the ram by pivot pin connections adjacent opposed ends of the link arm. An interconnecting bar interconnects the lever member of each linkage assembly together by a further pivot pin connection adjacent opposed ends of the interconnecting bar.
