PART 1: Tensioning Side | TWIN BUNDLE | Horizontal Rigging

/ Anchoring, General Rigging, Pulley Systems, Team Competencies / 8 Comments

  Tensioning Side: The tensioning of any highline system is one of the key elements to the success of the operation. This is even more critical for the rigging of multiple bundled highlines. Whether it is a twin or quad bundle system each rope of the trackline must receive an equal amount of tension. During

The “A” Frame: The floating A Frame is very similar to that of the single trackline, other than there are now two ropes in the trackline to deal with. This little segment addresses some of the specific aspects of a high directional anchor during the operation of a multi-bundle highline system. Sterling Rope is the

Carriage System The carriage system for a twin bundle or quad bundle highline is very similar to the single trackline. At this point of the discussion, We can now see how much tighter the trackline is. Each rope of the trackline is about the same tension as the single system…in this case we have two
