Abstract: An end link for use with heavy equipment includes a body and a swivel ball bushing. The body has first and second openings and defines a main body plane. The first opening has a slot located on a side thereof proximate the second opening and a truncated substantially spherical inner surface. The swivel ball bushing is seated within the first opening. The swivel ball bushing has a truncated substantially spherical outer surface in nesting engagement with the inner surface of the body and a projection at one end seated in the slot. The projection and slot are shaped to allow rotation of the swivel ball bushing relative to the body in two opposing directions about one axis of rotation or two mutually perpendicular axes of rotation.

Abstract: A repair link for chain comprises a body and first and second loop sections. The body has a longitudinal axis. The first loop section extends from the body and defines a first loop opening with a first loop axis extending normal to the first loop opening. The second loop section extends from the body opposite the first loop section. The second loop section defines a second loop opening with a second loop axis extending normal to second loop opening. The first loop axis and the second loop axis are non-parallel. Each of the first and second loop sections has a removable loop segment. Each removable loop segment is removable to open the respective loop opening to couple the repair link to another link of chain, and reassembleable with the respective loop section in a locked position to secure the removable loop segment and enclose the respective loop opening.
