Abstract: A jaw plate retainer assembly is arranged to releasably secure a jaw plate at a jaw of a jaw crusher. The retainer assembly is configured specifically for positioning at a rearward region of the jaw plate, such that no part of the retainer assembly is exposed to the crushing chamber and to protect it when mounted in use by the jaw plate.

Abstract: A jaw crusher retraction assembly having a base, a first and second mount boss, a resiliently biased component and an actuating cylinder. The cylinder and resiliently biased component are mounted axially between respective regions of the base and the first and second bosses so as to minimize stress in the retraction assembly components and to provide a compact overall design.

Abstract: A jaw plate for a jaw crusher has jaw mounting components positioned exclusively at a rear mount face of the plate. In particular, the jaw plate has at least the first and second mount flange projecting rearwardly from a rear mount face being engagable with respective retaining assemblies so releasably mount the plate at the jaw. The present jaw plate being arranged to prevent damage to the retaining assemblies during use.

Abstract: A jaw crusher having a movable jaw support frame configured to facilitate interchange between shim and wedge settings. The support frame is configured specifically to minimize stress concentrations and to provide the time efficient interchange between wedge and shim settings without a need to weld, cut and machine regions of the support frame.

Abstract: A jaw crusher retraction assembly having a base, a first and second mount boss, a resiliently biased component and an actuating cylinder. The cylinder and resiliently biased component are mounted axially between respective regions of the base and the first and second bosses so as to minimize stress in the retraction assembly components and to provide a compact overall design.

Abstract: A movable jaw mounting assembly to provide adjustment of the close side setting (CSS) of a movable jaw and to act as a retraction assembly or assist with retraction. The assembly includes a pair of linear actuators that are coupled between the back frame end and a region of the toggle unit so as to move the toggle unit towards and away from the back frame end to allow insertion and removal of spacers and/or shims.

Abstract: A jaw crusher movable jaw support frame mounts a linkage assembly for suspending a movable jaw in a floating relationship within a jaw crusher relative to a stationary jaw. The support frame includes reinforcement regions extending along a main force transmission wall to absorb and transmit loading forces imparted to the support frame from the movable jaw.

Abstract: A jaw plate part for securing jaw plates to a jaw crusher of the jaw crusher can be arranged to work as a wedge being detachable from the jaw crusher. The jaw plate part includes a front face and a rear face. The rear face of the jaw plate part has at least one recess having a first dead end. The recess, in at least one region, includes a shoulder, wherein a width of the recess at least closest to the shoulder on a side of the shoulder facing the first dead end is larger than the width of the recess at least closest to the shoulder on a side of the shoulder facing the rear face. The invention also concerns a jaw plate part unit having at least one such jaw plate part and fastening means. Moreover, the invention also concerns a jaw crusher having at least one jaw plate part unit for securing jaw plates of the jaw crusher.

Abstract: A jaw crusher support frame having a frame plate bordered by a pair of side walls that extend lengthwise along the frame plate, the support frame being strengthened and stiffened by a saddle that projects rearwardly from the support frame between the pair of side walls.

Abstract: A jaw crusher movable jaw support frame to mount a linkage assembly for suspending a movable jaw in floating relationship within a jaw crusher relative to a stationary jaw is provided. The support frame includes reinforcement regions extending along a main force transmission wall to absorb and transmit loading forces imparted to the support frame from the movable jaw.

Abstract: An assembly for supporting a jaw crusher frame on a foundation includes a foot adapted to cooperate with the foundation and the frame for supporting the frame on the foundation and a projection connected to the frame and extending substantially horizontally therefrom, the projection having a mainly downwardly facing supporting surface, which has the shape of a part, spanning at least 180°, of a first circular-cylindrical surface. The foot is adapted for attachment to the foundation and has an upwardly open recess, into which the projection is to be lowered and which has a bottom surface, which has the shape of a part, spanning not more than 180°, of a second circular-cylindrical surface and against which the projection, when lowered into the recess, is to abut with its supporting surface. The first and the second circular-cylindrical surface have substantially the same diameter.
