Abstract: A one piece three-sided hardened steel boot tip for a distal end upper jaw tang of a heavy duty demolition shear having a upper movable shear jaw with a shear tip or tang. The boot tip has a front wall seated on the tang front edge and a right sidewall. A bottom wall of the boot tip is seated on the tang bottom seat forming a shear punching edge between the front wall and the bottom wall. A sidewall is connected to the tang bottom and front walls with a shearing edge between the side and bottom walls. A side plate with an indexing hub is seated on the guide side tang face, the top seat and the rear seat.

Abstract: A one piece four-sided hardened steel boot tip for a distal end upper jaw tang of a heavy duty demolition shear having a upper movable shear jaw with a shear tip or tang. The tang has a front edge, side faces with apertures therethrough, a top seat, a rear seat and a bottom seat. The boot tip has a front wall seated on the tang front edge and a right side wall seated on the shear side tang face, rear seat and the top seat. A bottom wall of the boot tip is seated on the tang bottom seat and rear seat forming a shear punching edge between the front wall and the bottom wall. An access plate is seated on the guide side tang face, the top seat and the rear seat. The boot tip right side and access plate have matching apertures therethrough and alignable with the tang apertures to secure the boot and access plate to the tang. One or more shims may be used against the tang faces.

Abstract: A one piece four-sided hardened steel boot tip for a distal end upper jaw tang of a heavy duty demolition shear having a upper movable shear jaw with a shear tip or tang, a shear side and a guide side pivotally connected to a lower fixed or movable shear jaw with a shear blade side, a guide side, a distal tie plate and a recess therebetween. The tang has a front edge, side faces with apertures therethrough, a radiused top seat, a radiused rear seat and a radiused bottom seat. The boot tip has a front wall seated on the tang front edge and a right side wall seated on the shear side tang face and radiused rear seat. A top wall has a radiused inside top wall that sits on radiused top seat. A bottom wall of the boot tip has a radiused inside top wall that is seated on the tang radiused bottom seat forming a shear punching edge between the front wall and the bottom wall. A shear side shearing edge is between the sidewall and the bottom wall of the boot tip.

Abstract: An adjustable shimable indexable shear tip for a distal end tang of a heavy duty demolition shear having a upper movable shear jaw with a shear side and a guide side pivotally connected to a lower shear jaw with a shear blade side, a guide side, a distal tie plate and a recess therebetween. The tang has side faces with apertures therethrough, a top seat, a rear seat and a bottom seat. The adjustable shimable shear tip has a two-sided shear tip section with a sidewall and a bottom wall that is adapted to be seated on one of the side tang faces, the top seat, the rear seat and the bottom seat. The bottom wall is formed with the sidewall at a shear edge and is adapted to be seated on the tang bottom seat with a leading shear punching edge. A side plate is adapted to be seated on the other tang side face, the top seat, the rear seat with another shear edge along the bottom wall.

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.
