Abstract
A liner for a body such as of an off-highway truck protects the body from wear. The liner has a plate with openings through the plate arranged in a preselected pattern. The plate is of a size to fit a particular portion of the body and is typically removably fastened to the body. The openings in the plate cause material to tumble, instead of to slide, when being removed from the truck. The tumbling action, and the thickness of the plate, reduces wear on the body during material dumping.
Claims14
A prefabricated liner for a high wear portion of the body of a work machine, said body being positionable in a substantially upright position in which load :material is ejected from the body, comprising:
- a plate having top and bottom surfaces, a plurality of openings, and being of substantially the same size as the high wear portion of said work machine body, said openings passing through said plate from said top surface to said bottom surface and being arranged in a preselected pattern, said openings causing said load material to tumble rather than slide across the top surface of said plate when said material is ejected from said body, said bottom surface being of a configuration sufficient for resting on said work machine body for said plate to support loads in said work machine body.
A load-carrying body for a work machine, comprising:
- a bed having first and second sides, a bottom and a rear opening, said first and second sides and said bottom being connected to form a material containing cavity, said bed being adapted to be positioned in a substantially upright position in which load material is ejected from said material containing cavity;
- and
- a plate having top and bottom surfaces, a plurality of openings, said openings passing through said plate from said top surface to said bottom surface and being arranged in a preselected pattern, said bottom surface of said plate resting on said bed, said plate being positioned in fitted relationship with at least a part of said bed in a manner sufficient for supporting loads in said bed, said openings in said plate causing load material ejected from said material containing cavity when said bed is in an upright position to tumble rather than slide across the top surface of said plate.
A work machine adapted to transport and dump load material, comprising:
- a chassis;
- a load-carrying body carried on the chassis and movable between a substantially horizontal load carrying and receiving position and a substantially upright load ejecting position, said body comprising;
- a bed having first and second sides, a bottom and a rear opening, said first and second sides and said bottom being connected to form a material containing cavity;
- and
- a plate having top and bottom surfaces and a plurality of openings, said openings passing through said plate from said top surface to said bottom surface and being arranged in a preselected pattern, said bottom surface of said plate resting on said bed, said plate being positioned in fitted relationship with at least a part of said bed in a manner sufficient for supporting loads in said bed, said openings in said plate causing load material ejected from said material containing cavity when said body is in the load ejecting position to tumble rather than slide across the top surface of said plate.
