HEAVY-DUTY DEMOLITION APPARATUS WITH BLADE STABILIZING DEVICE

摘要

A blade stabilizer device for a heavy-duty material handling demolition tool (10) for shearing and crushing scrap material which includes a lower jaw (12) connected to the boom structure of a hydraulic system of an excavator and has an upper jaw (14) pivotally connected and closeable upon the lower jaw (12) at a pivot point (16). The blade stabilizing device (38) consists of a wear guide pad (66) supported by the lower jaw adjacent the pivot point (16) slidably engaging the upper movable jaw (14) to keep the upper jaw in close engagement with the lower jaw (12). The wear guide pad is mounted behind the pivot point (16). A second wear guide pad (66) may be mounted in front of the pivot point (16) on the opposite side of the upper jaw to cross-brace the upper jaw.
