Crusher clearing system

A system 100 and method for clearing a crushing device 1 of tramp material is disclosed. The system comprises at least one dual-acting cylinder 70 which serves to both maintain a constant crushing force between a head 500 and bowl 400, and also provide a clearing stroke to facilitate passage of said tramp material. The body of the at least one dual-acting cylinder 70 is mounted securely to a main frame 300 in a self-centering, self-seating arrangement by cylinder mount 40. The piston rod 30 of the at least one dual-acting cylinder 70 is directly or indirectly mounted securely to an adjustment ring 200 in a self-centering, self-seating arrangement. The piston rod 30 comprises a first securing member 10 and a second securing member 20. A mounting portion 202 associated with the adjustment ring 200 is captured between the first 10 and second 20 securing members of the piston rod 30.
