TT Box Truss (TT-B)

Tower Truss for use as a horizontal beam truss

The TT series is a Medium Duty Compact Tower Truss, designed for use as a horizontal beam truss with fully hinged spigots that can be used in either orientation, horizontal or vertical without affecting the loading characteristics.

The TT Truss is designed for use as a tower, and so is a single section of genuine multi-purpose truss making it ideal for rental and production companies.

The TT Truss end connection is designed to allow the truss to articulate. This allows the creation of faceted shapes by using the spigots vertically or horizontally whilst maintaining the overall strength of the components.

Notes 1. Above allowable loads may be increased by 1.11 for Wind Loading Only.
2. This table is provided as a guide only and assume all loads are applied at nodes. All scaffolds and structures should be checked by a qualified structural engineer.
3. Maximum capacity of a point load mid way between nodes is 6kN.
4. For design purposes assume: allowable bending moment = 13.0 kNm, allowable shear = 13.0 kN.
