Although the entire system is made of medium duty and heavy duty trusses (approximately 65' deep and 100' wide at its widest point) the equipment is not the typical standard product. To achieve the desired look, no guide cables were used to secure the system. In light of this design consideration, Tomcat came up with a solution utilising eight 34ft medium duty spigoted towers with diagonals on all four faces of the truss.
The main vertical spans complete the modified grid and are comprised of heavy duty spigoted truss. These spans had their own design requirements since there will be acrobatic equipment in addition to lighting and sound installed on these trusses. Like the towers, all of these main truss spans include diagonals on all four faces to resist the stress of potential lateral loads.
