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: A jaw crusher has a substantially fixed jaw and an opposed movable jaw. A pair of opposed side walls extend from either side of the jaws to define a crushing zone. Each side wall includes one or a plurality of side liners configured to protect the side walls. A security or capture projection extends from the side wall to one side and adjacent to each side liner and prevents the side liner from falling downward from the crushing zone in the event of dislodgement from its mounting position during use.

Abstract: A set of jaw crusher shims for positioning a movable jaw of a jaw crusher, the shims having at least a first and a second shim. Each of the first and second shims including projecting portions arranged to aid with loosening of the shims from each other. The first shim includes a first projecting portion and the second shim includes a second projecting portion. The first and second projecting portions are located at different locations along respective front edges of the first and second shims.

Abstract: A jaw crusher includes s a toggle beam having a piston rod arrangement seat, a toggle plate, a first toggle plate seat arranged between the toggle plate and a movable jaw, a second toggle plate seat arranged between the toggle plate and the toggle beam, and a positioning device having a movable piston rod arrangement received by the piston rod arrangement seat of the toggle beam. The jaw crusher further has a toggle plate squeezing device including a contraction member. The squeezing device has a first mounting member connected to the movable jaw, and a second mounting member connected to the piston rod arrangement, to exert a pressing force on the first toggle plate seat, the second toggle plate seat and the piston rod arrangement seat.
