Ground engaging wear member and means of mechanical attachment

A wear member assembly for attachment to a wear member receiver provided on an outer surface of an earth moving apparatus member,

• the wear member receiver having at least first and second contact portions and an aperture to receive a wear member locating member of a wear member assembly,
• the wear member assembly including a releasable attachment mechanism arranged to releasably attach the wear member to the wear member receiver,
• the wear member assembly having a moveable attachment member and a fastening means such that actuation of the fastening means moves the attachment member to apply a retaining force to one of the contact portions of the wear member receiver and causes the wear member locating member to apply a retaining force to the other of the contact portions of the wear member receiver,
• at least one of the wear member receiver first and second contact portions has a tapered face and the wear member locating member or the attachment member has a corresponding taper such that contact between the wear member locating member taper or the attachment member taper and a corresponding one of the wear member receiver tapered contact portions causes the wear member to positively locate to the receiver thereby releasably retaining the wear member to the outer surface of the earth moving apparatus member.

An earth moving apparatus member having an outer surface with a wear member receiver located on said outer surface,

• the wear member receiver having at least first and second contact portions and an aperture to receive a locating member of a wear member, and wherein
• the wear member is a component of a wear member assembly and is arranged to releasably attach to the receiver on the earth moving apparatus,
• the wear member assembly further including a releasable attachment mechanism arranged to releasably attach the wear member to the wear member receiver,
• the wear member assembly having a moveable attachment member and a fastening means such that actuation of the fastening means moves the attachment member which causes the attachment member to apply a retaining force to one of the first and second contact portions of the wear member receiver and causes the wear member locating member to apply an opposite retaining force to the other of the first and second contact portions of the wear member receiver,
• at least one of the wear member receiver first and second contact portions is tapered and the wear member locating member or attachment member has a corresponding tapered such that contact between the wear member locating member tapered face or attachment member tapered face and a corresponding one of the tapered first or second contact portions of the receiver causes the wear member to positively locate to the wear member receiver thereby releasably retaining the wear member to the outer surface of the earth moving apparatus member.
