Abstract: A collapsible truss and method that is particularly suitable for staging and lighting, for shows, performances and other events. This evolved and novel modular truss can be collapsed to a significantly smaller size (i.e. increased density), and consequently requires significantly less space for storage and transportation. Further, in addition to the advantage of rapid assembly from collapsed parts to a full truss, the modular construction of the truss provides cost effective repair of this truss over traditional rigid welded trusses by simple replacement of damaged parts.

Abstract: A tension monitoring assembly or device permanently installed between a connection or anchor point and a guy cable line or structural rod allows constant monitoring and increase confidence that the guy cable or structural tension rod remains tensioned to the proper value. The device includes a plurality of compression members and a connecting member that are arranged between connection points such that the tension between a first connecting point and a second connection point may be set to a selected value. The tension on the device is determined by the distance between two members of the device such that a change in the tension from a set amount will result in a change of the distance between the two members. This change in distance can be determined by indicia that are visible as the two members move with respect to each other.

Abstract: A rotating connector that is particularly suitable for staging and lighting trusses and that includes a rotating connector and an inside sleeve having at least two portions. The combination of the rotating connector and the sleeve are held together by an outside sleeve, and the assembled sleeve is attached to a truss member.
