A wear protection system is disclosed for protecting a parent member of an earthworking machine, such as a bed of an off-highway truck for instance. The protection system includes a replaceable wear member, which is detachably mounted to a mounting base by a retainer. The wear member is provided with a skeletal frame with a large window-like opening and outstretched legs to reduce the weight of the wear member. The pockets formed by the window opening and in the spaces between adjoining wear members fill with material so as to insulate the parent member of the truck bed from frictional wear due to material sliding over the bed when dumping material therefrom. |
