Abstract: An articulating cab assembly for vehicles with an elevated frame, such as excavators, is described. The cab assembly includes a cab coupled to a pivot plate, wherein the pivot plate is coupled to a cab assembly mounting framework. A cab extendable link is pivotally connected to the cab and the pivot plate, for moving the cab between an elevated operating position and a lower ground level operator load and unload access position. The cab assembly also includes a framework extendable link that is pivotally connected to the pivot plate and to the cab assembly mounting framework, for moving the pivot plate forwardly and rearwardly without pivot plate rotation. The cab is in a fully lowered position when the extendable links are each at a minimum extension, and the cab is in a fully raised position when the extendable links are each at a maximum extension.

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