Abstract:
In view of the above, there has been described a load compensator including one or more tension spring assemblies that are contained within a tubular housing when tension from a load is applied to the tension spring assemblies. When the load compensator includes more than one tension spring assembly, the tension spring assemblies are mechanically connected to each other in series and stacked in-line with each other in the housing. In a preferred construction, each of the tension spring assemblies includes elastomeric tension elements mounted between two disks, and the tubular housing includes a tube having threaded ends and caps that screw onto the tube.
