Abstract:
A pre-loading system for a pipe handling apparatus in which a boom is pivotally mounted at one end to a skid and in which an arm is connected to an opposite end of the boom. The pre-loading system has a tensioning assembly with one end affixed to the arm and an opposite end fixedly mounted so as to apply tension to the arm when the arm has a load applied to an end of the arm opposite the boom. The tensioning assembly includes a first cable assembly having one end connected to the arm and an opposite end fixedly mounted, and a second cable assembly connected to the arm and having an opposite end fixedly mounted. The first and second cable assemblies extend from opposite sides of the arm.
