Guyline tension device for communication towers

A cabling system for raising and lowering a nesting tower structure comprising:

• at least three ground anchors set out from and peripherally around a nesting tower structure;
• at least one pulley secured to each of said ground anchors;
• a like number of cables, one end of each cable being secured to the tower structure and trained around one of said pulleys;
• and means for tensioning said cables and maintaining a preselected tension on said cables as said tower structure is raised or lowered, said means for equalizing the tension in each of said cables comprising a pair of first class levers, one lever connected at a center fulcrum point to a pivot on the other, the tension forces of two cables being applied equal distances from and on opposite sides of said fulcrum point, the pivotal connection to said second lever acting with a moment arm relative to the fulcrum point on said second lever to balance the tensioning force of a third cable connected to a second pivot point on said second lever and having a fourth cable attached to the fulcrum point of said second lever whereby tension on said fourth cable will be applied equally to the first three cables.
