Clamp systems include multiple, separate clamps joinable to components subject to relative rotation. Clamps may have similarly-positioned features to simplify installation and/or removal about a small area for all clamps in the system. Each clamp cannot freely rotate relative to an adjacent clamp but does not pass vertical loads to an adjacent clamp. Clamps may use mating shapes like an extension and recess to limit rotation. Clamps fit to the perimeters of components to which they individually secure by biasing against the components. At least one clamp has a transitional surface to provide space between the clamp and component to provide containment to a weld or other joining structure. Clamp systems can be tightened by included fasteners. Crimp nuts or other locking structures can preserve the biased and secured nature of the clamps and underlying structures. Clamp systems may be used to secure or repair a lifting rod assembly.
