Abstract
A tip assembly for a jaw of a jaw set for demolition and construction equipment has a base with a top side, an underside, and a protrusion extending along a longitudinal axis and extending from the underside. The tip also has a first insert mounted to the base and a second insert mounted to the base. Each insert has a first wall and an opposing second wall with a front side extending therebetween. Each insert also has a locking recess that conforms to the protrusion to limit movement of the insert in directions perpendicular to the longitudinal axis.
Claims15
A tip assembly for a jaw of a jaw set for demolition and construction equipment comprising:
- a base having:
- a top side comprising a mounting surface for engaging a surface of the jaw and an underside opposite the top side;
- a protrusion protruding from the underside away from the top side and extending along a longitudinal axis;
- a first insert mounted to the base and a second insert mounted to the base, wherein each insert has:
- a first wall and an opposing second wall with a front side extending therebetween;
- and
- a locking recess that conforms to the protrusion to limit movement of the insert in directions perpendicular to the longitudinal axis,
- wherein the base further comprises a support bar spanning between the protrusion and a remaining portion of the underside of the base,
- wherein the protrusion comprises a generally trapezoidal cross-sectional shape such that the protrusion is wider toward a bottom of the protrusion and narrower toward a top of the protrusion where the protrusion protrudes from the underside of the base, and
- wherein the base having the top side, the underside, and the protrusion is removable from the jaw.
A tip assembly for a jaw of a jaw set for demolition and construction equipment comprising:
- a base having a top side for engaging a surface of the jaw, an underside opposite the top side, a protrusion protruding form the underside away from the top side, and a support bar spanning between the protrusion and a remaining portion of the underside of the base;
- and
- an insert comprising:
- a first wall and an opposing second wall with a front side extending therebetween, wherein an edge of the first wall is a piercing edge;
- and
- a locking recess extending within the first wall;
- a first bore having a first bore diameter and inner and outer bore walls, wherein the first bore extends through the first wall and second wall;
- a second bore having a second bore diameter and inner and outer bore walls;
- wherein the inner bore wall of the first bore is spaced from the inner bore wall of the second bore by a length at least equal to the diameter of the first bore wall, and
- wherein the locking recess comprises a generally trapezoidal cross-sectional shape extending into the first wall such that the locking recess is wider toward a bottom of the locking recess and narrower toward a top of the locking recess where the locking recess is open.
