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.
