ABSTRACT:
A crushing apparatus has an hydraulic cylinder for actuating a toggle mechanism connected to a moveable jaw. The apparatus may have a main frame with an opening near the top of the frame for admitting material to be crushed. There is a first jaw connected to the frame on one side of the opening by a first pivotal connection near the top of the jaw. A first toggle mechanism is operatively associated with the first jaw. There may also be a second jaw connected to the frame on a side of the opening opposite the first jaw by a second pivotal connection near the bottom of the second jaw. A second toggle mechanism is operatively associated with the bottom mounted jaw. The crushing apparatus may have a toggle mount which is movable towards or away from the associated jaw.
