ABSTRACT:
A retention and positioning device is disclosed for a crusher having a main frame with an upper seat, and an upper frame held in releasably biased relation to the main frame and including a portion engaging the upper seat during normal operation. The retaining and positioning device includes a bracket constructed and arranged for retention upon the upper seat during operation of the crusher, the bracket defining at least one pad aperture, and at least one shock absorbing pad configured for retention in each aperture. During operation of the crusher, when the upper frame is momentarily displaced from engagement with the main frame, the return of the upper frame to the upper seat is cushioned by the at least one pad.
