Abstract

A hydraulic safety system for a material handling attachment with interchangeable jaw assemblies. The hydraulic safety system includes a hydraulic safety manifold that ports fluid pressure to rods sides and bleeds fluid pressure from base sides of a hydraulic cylinders coupled to locking pins securing the interchangeable jaw assemblies to a main body of the material handling attachment. The hydraulic safety manifold ensures that hydraulic pressure on the base sides of the cylinders will remain less than or equal to pressure on the rod sides of the hydraulic cylinders even in the event of a hydraulic leak.

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 pulverizing attachment for an excavator and a method of removably rigidly retaining teeth to one or more jaws of a pulverizer. A plurality of tooth members each have a longitudinal slot with a cross-sectional shape and a relief slot extending substantially transverse to the longitudinal slot producing a flexible end portion capable of deflection upon application of a longitudinal compression force. The tooth rails having a complimentary cross-sectional shape to the longitudinal slot slidably receive the tooth members. The complimentary shape of the longitudinal slot and tooth rail in cooperation with a longitudinal compression force applied to deflect the flexible end portions of each of the tooth members rigidly retains the tooth members on the tooth rails fixed to the pulverizer jaws.

Abstract

This heavy-duty demolition apparatus (10) includes a unitary jaw assembly, having a pair of pivoting jaws (12, 14) connected by a main pivot pin (16); a first adaptor (50) on the boom structure; a second adaptor (60) on the jaw assembly, the second adaptor engaging the first adaptor, so that the jaw assembly can be easily removed as a unit from the boom structure; and a lock pin (70) fixed to the first adapter (50) and engaging the second adapter (60) to maintain the jaw assembly in locked relationship to the boom structure. Because of the structure of the apparatus (10), the distance between the attachment point of the hydraulic ram on the boom structure and the main pivot point of the jaw assembly can be varied between interchangeable jaw assemblies.
