AI Technical Summary

Benefits of technology

The present invention is related to a wear pack for a jaw of a demolition tool, which is used to shield the front end of the jaw. The wear pack includes a wear member with a contact surface to rest against the front end, and a bracket member that projects from the wear member and mates with a reciprocal mounting surface on the front end. The bracket member has a mounting surface with a positioning portion that aligns with a force transfer portion, which allows for easy assembly and secure attachment of the wear pack to the jaw. The technical effect is that the wear pack improves the tool's durability and reliability by protecting the front end of the jaw, which comes into contact with the demolition material.

Problems solved by technology

The abrasive nature or hardness of some of these materials may cause the relatively rapid wear of the surfaces that engage the materials.

Embodiment Construction

[0019]This disclosure generally relates to a wear pack 10 for assembly onto a jaw set of a demolition tool.

[0020]FIG. 1 illustrates the wear pack 10. The wear pack 10 may be composed of a material or a composite of materials that are resistant to wear due to operation of the demolition tool. The wear pack 10 may be composed of high strength steel.

[0021]FIG. 2 illustrates the wear pack 10 mounted to a jaw set 50 of a demolition tool. Although the wear pack 10 is shown mounted to a jaw 52 of the jaw set 50, the present disclosure should not to be limited to this embodiment.

[0022]The wear pack 10 may be configured to fit to an upper jaw 51 or the lower jaw 52 of the jaw set 50. The wear pack 10 may be configured to fit to a front end 53 of the jaw 51 or a front end 54 of the jaw 52. The front ends 53, 54 may be the free ends that are opposite the pivotally connected ends of the jaws 51, 52.

[0023]With reference to FIG. 1, the wear pack 10 may comprise a wear member 12. The wear member 1...

Abstract

A wear pack is disclosed for shielding a front end of a jaw set of a demolition tool. The wear pack may have a position portion provided on a bracket member for the alignment thereof prior to mounting. The wear pack may have a force transfer portion provided on the bracket member for the transfer of demolition forces to the front end of the jaw. The positioning portion may be contiguous with the force transfer portion.

Description

TECHNICAL FIELD[0001]This disclosure relates to the field of demolition tools for crushing and / or cutting material and more particularly to the field of wear packs for demolition tools.BACKGROUND[0002]A demolition tool for crushing and / or cutting material is generally known. Typically, the demolition tool may comprise a jaw set having a lower jaw and an upper jaw. The upper and lower jaws may be pivotally connected. The upper and lower jaws may be moveable relative to each other. Blades may be provided on both the upper jaw and the lower jaw. The work material may be crushed or cut by closing the upper jaw against the lower jaw under hydraulic pressure.[0003]The demolition tool may comprise a frame that connects the jaw set to a jib of a machine.[0004]The demolition tool may have a jaw set that is suitable for crushing concrete. The jaw set may be adapted for crushing or cutting other materials, for example for cutting scrap iron and / or iron sections. The abrasive nature or hardness...
