JAMESSUPER-TRUSS20.5 x 20.5ENGINEERINGThomas has rethought truss design to encompass the changing demands of the touring industry. The supertrussdesign features new double end connectors, which are orientated, so that the truss elements are unisex ( they can beused either way ). Made from 6061T6 or 6082T6 alloy, the truss has 2" x 0.157" main chord tubes and 1" x 0.125"diagonal tubes.Supertruss saves truck space because of its very high strength in relation to its size and also the space savingdesign of the corners.The corners are simplicity themselves. As for the 2 way corner, only a connecting gate is required to bracebetween the outer fork connectors. The 3 way corner only requires a connecting gate and 2 square connectingplates. The 4 way corner requires just 2 square connecting plates. In order to use the supertruss with towers, 2sleeve connecting plates with roller wheels are required with 1 or 2 ladders depending on how many trussconnections their are. 60 degree corners require 2 extended double fork connectors and a connecting gate. Otherangles can be easily made to order. Variable and vertical connecting forks are available for 0 - 90 degree operation.PRODUCTCODEB1360B1361B1362B1363B1364B1365DESCRIPTION12' Section10' Section8' Section6' Section5' Section2' 6" SectionWTlbs90.57770.558.549.538.5B130060 Degree corner gate33B1301B130290 Degree corner gate120 Degree corner gate1110B1303135 Degree corner gate8.5B13043 Way gate9.5B13053 Way gate with lifting point9B1306Vertical connecting fork1.3B1307B1308Horizontal connecting forkSquare support plate2.211B1309A12" Tower sleeve plate26.5B1309BB1311B131215" Tower sleeve plateSuper-truss to GP20.5x20.5 adaptergateLifting point for super-truss26.5--LOADING FIGURES show maximum loads between supports inaddition to self weight of truss.
