Claim Text:
1. A jaw crusher support frame to support a movable jaw of a jaw crusher via a mechanically actuated link assembly connected to the movable jaw, at least a part of the link assembly configured to allow the movable jaw to oscillate relative to a substantially stationary jaw in order to crush material in a zone between the movable and stationary jaws, the support frame comprising: a force transmission wall extending generally in a plane transverse or perpendicular to a longitudinal axis of the link assembly, the force transmission wall having a first side facing the movable jaw and a second side to be rear facing away from the movable jaw; a piston aperture in the force transmission wall to allow a piston to extend from the first side-of the force transmission wall, the piston being connected to a mechanical actuator positioned at a region of the second side of the force transmission wall; and first and second reinforcement end regions extending along respective first and second lengthwise ends of the force transmission wall, each end region having a first and a second flange, the first flange projecting forward from the first side of the force transmission wall to extend towards the movable jaw and the second flange projecting from the second side of the force transmission wall to extend away from the movable jaw, wherein the first and second flanges are curved relative to a plane of the force transmission wall such that the first and the second flanges curve back towards the plane of the force transmission wall.
