Abstract:
For use with a horizontal shaft impact crusher having a frame defining a cavity, a breaker plate and a pair of adjusting rods supporting the breaker plate within the cavity, the adjusting rods extending out of the cavity, an apparatus for selectively relieving the load on the adjusting rods comprising:a first linear actuator mounted to the frame outside of the cavity, the first linear actuator having a first position and a second position; anda bridge having a first bearing section disposed adjacent the first linear actuator, the bridge being secured to each of the adjusting rods such that, as the first linear actuator moves from the first position to the second position, the first linear actuator applies a force to the first bearing section to thereby at least partially relieve the load on the adjusting rods, the bridge being sized such that, when the first linear actuator is in the first position, the bridge does not add to the height of the crusher.
