A load compensator comprising a tubular housing; and at least one tension spring assembly having a first end adapted for connection to a load and a second end mechanically connected to the tubular housing so that tension from the load is applied to the tension spring assembly, wherein said at least one tension spring assembly is disposed within the tubular housing and the first end of said at least one tension spring assembly slides against an inner surface of the tubular housing when said at least one tension spring assembly elongates as the tension from the load is applied to the tension assembly, and the tubular housing has a fixed length greater than a length of said at least one tension spring assembly when said at least one tension spring assembly has a maximum elongation under a maximum amount of tension from the load so that said at least one tension spring assembly is contained within the tubular housing under the maximum amount of tension from the load; a crush pad mounted to the housing and configured to be crushed and permanently deformed by elongation of said at least one tension spring assembly when tension applied from the load exceeds a threshold.
