Abstract: A piercing tip for a demolition shear, the piercing tip including a blade-side sidewall and a guide-side sidewall, a front wall, and a bottom wall. An intersection of a front outer wear surface of the front wall and a bottom wear surface of the bottom wall defines a front piercing edge. An intersection of a planar outer wear surface of the blade-side sidewall and the bottom wear surface of the bottom wall defines a shearing edge. A blade set may include the piercing tip and at least one shear blade. The piercing tip and at least one shear blade may be mounted to the blade-side of an upper jaw of the demolition shear.

Abstract: A demolition shear and a piercing tip insert and nose configuration for a demolition shear which resists nose wear and resists retract forces exerted on the piercing tip insert in jamming situations and in the event of snagging of the piercing tip insert. The piercing tip insert includes first and second piercing tip halves, each half having an outer planar sidewall, a curved front wall extending laterally inward, and a bottom leg extending laterally inward defining a shearing edge and a piercing edge.

Abstract: A slewing ring grease assembly for providing grease to internal gear teeth of a slewing ring. The slewing ring grease assembly includes a bulkhead fitting having a flange and a shaft, the shaft extends through a hole in the bulkhead attached to the slewing ring such that the shaft extends over the internal gear teeth of the slewing ring. The bulkhead fitting flange is secured to the bulkhead on a side opposite the internal gear teeth of the slewing ring. A passage through the bulkhead fitting is provided which is capable of delivering grease through the bulkhead fitting and onto the internal gear teeth of the slewing ring. The grease assembly may include a wall fitting extending through a wall of housing supporting the bulkhead and a connecting tube capable of delivering grease from the wall fitting to the passage of the bulkhead fitting.

Abstract: A hydraulic swivel assembly includes a hydraulic swivel having a plurality of ports on a base and a plurality of ports on a rotatable extension. A manifold block is secured to the base, and has a corresponding plurality of ports matingly aligning with the plurality of ports of the base, whereby the plurality of ports of the manifold block are adapted to couple to a first set of hydraulic lines from a non-rotating member and the plurality of ports on the rotatable extension are adapted to couple to a second set of hydraulic lines which rotate with the rotatable member.

Abstract: A demolition shear and a piercing tip insert and nose configuration for a demolition shear which resists nose wear and resists retract forces exerted on the piercing tip insert in jamming situations and in the event of snagging of the piercing tip insert. There is a need for a demolition shear having a piercing tip insert and nose configuration to reduce nose wear and to resist retract forces exerted on the piercing tip insert in jamming situations and in the event of snagging of the piercing tip insert.

Abstract: A hydraulic orange peel material handling grapple that is attachable to a boom stick on a material handling machine is used for recycling or material handling in grabbing odd shaped objects, unprocessed scrap and scooping up small items and shredded scrap. The grapple includes a central tower having at least four aligned upper and lower mounting ears circumferentially arranged equally distant from each other. A hydraulic cylinder with a ram is mounted to each upper ear. A set of at least four interchangeable pointed-shaped tines are provided for grabbing the odd shaped objections and unprocessed scrap. A set of four interchangeable flat-shaped tines that are used for scooping up small items and shredded scrap are also provided. Each tine has a cylinder ram mount ear on an upper portion of the tine for mounting the cylinder ram and an uppermost mount distal from the tine tip for pivotally mounting the tine to one of the lower frame mounting ears.
