摘要:
An active rigging system, using multiple lines to support a load, places a constant tension on at least one of the lines. The constant tension allows a resistance to slack in the line, which in turn allows the line to maintain support of the lines' respective share of the load. This configuration allows a reduction of stress in the load and an enablement of support of loads having an unequal weight distribution. Additionally, the invention includes a method for relieving stress from a load, supported by multiple lines generally susceptible to slack. The method includes placing a constant tension on at least one of the lines to allow that line to resist slack. The resistance to slack involves utilizing a tension force and an adjustment of the line via a pulley.
