发明名称 APPARATUS AND METHOD FOR PRE-LOADING OF A MAIN ROTATING STRUCTURAL MEMBER
摘要 An apparatus for a pipe handling apparatus has a main rotating structural member rotating about a pivot axis relative to a skid and moving from a first position to a second position. A tensioning mechanism is affixed to the main rotating structural member. The tensioning mechanism applies a tension to the main rotating structural member when the main rotating structural member is in the second position. The tensioning mechanism has a first cable having an end attached adjacent a top of the main rotating structural member, and a second cable having an end attached adjacent the top of the main rotating structural member. The first and second cables have opposite ends attached to a fixed surface. The first and second cables extend angularly outwardly from a front of the main rotating structural member. The first and second cables extend angularly outwardly from the sides of the main rotating structural member.
