摘要： 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. An access or side plate is seated on the guide side tang face, a portion of the radiused boot bottom wall and the radiused rear seat. The side plate us flush with the bottom and front walls. 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 for protection thereof from the lower jaw shear side, the guide side and the tie plate as the upper jaw moves into and out of the recess. One or more shims are provided and insertable inside the boot against the tang faces and clampable thereto after the faces have become worn or otherwise requires adjustment for maximum clamping force. An extendable boss maybe insertably located on the lower inside face of the side plate as to index and interlock with a matching indexing bolt or boss recess on tank guide side face. A portion of the lower edge of the side plate has a guide side shearing edge.

摘要： 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.

摘要： A one piece four-sided hardened steel boot tip is mounted to a distal end upper jaw tang of a heavy duty demolition. 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 or curved rear seat. A top wall has a radiused inside top wall that sits on the radiused tang 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. The boot tip has a shear side shearing edge that is between the sidewall and the bottom wall of the boot tip. An access or side plate is seated on the guide side tang face, a portion of the radiused boot bottom wall and the radiused rear seat. The side plate is flush with the bottom and front walls. 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 for encapsulating protection thereof from the lower jaw shear side, the guide side and the tie plate as the upper jaw moves into and out of the recess therebetween. One or more shims may be provided that are insertable inside the boot against the tang faces and clampable thereto after the faces have become worn or otherwise requires adjustment for maximum clamping force.
