Abstract
The present invention provides a non-detachable chain link for a material mover chain. Chain link comprises a body portion having an aperture therethrough and a hook portion including a tip portion. A recess defined by the hook portion is adapted to contain one or more bearing surfaces on the body portion of an adjacent link in a chain comprised of a plurality of such links. The tip portion has a greater width than the aperture to prevent the hook portion from falling through the aperture of an adjacent link. This prevents chain links from coming detached during operation due to an object falling on the chain or excessive slack developing in the chain.
Claims6
A chain link for use in a material mover chain comprising:
- a body portion connected to a hook portion;
- wherein the body portion has an aperture therethrough;
- wherein the hook portion has a tip portion;
- wherein a width dimension of the tip portion is greater than a width dimension of the aperture;
- wherein the hook portion defines a recess which is adapted to receive a bearing surface on body portion;
- and
- wherein the bearing surface projects outwardly from an upper surface of body portion.
A chain link for use in a material mover chain comprising:
- a body portion connected to a hook portion;
- a material mover flight welded to the chain link;
- wherein the body portion has an aperture therethrough;
- wherein the hook portion has a tip portion;
- and
- wherein a width dimension of the tip portion is greater than a width dimension of the aperture.
A material mover chain comprising:
- a plurality of chain links interlocked with each other, wherein each chain link comprises:
- a body portion integrally formed with a hook portion;
- wherein the body portion has an aperture therethrough;
- wherein the hook portion has a tip portion;
- and
- wherein a width dimension of the tip portion is greater than a width dimension of the aperture;
- wherein the hook portion of each chain link defines a recess, and wherein the recess of each chain link receives a bearing surface on the body portion of an adjacent chain link;
- and
- wherein the bearing surface of each chain link projects outwardly from an upper surface of each chain link.
A material mover chain comprising:
- a plurality of chain links interlocked with each other, wherein each chain link comprises:
- a body portion integrally formed with a hook portion;
- wherein the body portion has an aperture therethrough;
- wherein the hook portion has a tip portion;
- and
- wherein a width dimension of the tip portion is greater than a width dimension of the aperture;
- and
- wherein a plurality of said chain links have material mover flights welded thereon.
