ABSTRACT:
A lifting mechanism for the pressing roller of the feed mechanism of a crusher for scrap. The rotor of the crusher, via a lifting mechanism that acts upon a mounting bracket of the rotor mounting, can be removed from a split housing after an upper part of the housing has been raised about a horizontal pivot axis and has been secured in position relative to a lower part of the housing, whereby pivot arms are disposed on opposite faces of the housing and are connected to hydraulic cylinders, with free ends of the pivot arms being pivotably mounted about a horizontal axis, and with the pivot arms being successively connected with the upper housing part to raise the same, with the mounting bracket after the upper housing part is secured relative to the lower housing part in an open position and the pivot arms have again been lowered, and again with the upper part after the rotor is removed. The pivot arms are extended beyond the contour of the housing toward the feed mechanism and are respective side arms of a U-shaped frame. The free ends of the side arms are disposed remote from the feed mechanism and are pivotably mounted, about a horizontal axis that is substantially aligned with the pivot axis between the upper and lower parts of the housing, on supports that are disposed next to the opposite faces of the housing without touching the same, and that are securely connected to a base.
