JAMESGP 18 x 12ENGINEERING18" x 12" manufactured the same way as 12" x 12", but has an added advantage, due to its width of 18"of being able to accommodate 2 lighting bars back to back. Also the truss is slightly stronger over longerspans. It is made from 6061T6 or 6082T6 alloy 2" x 0.125" tubes for the main chords and 1" x 0.125"tubes for the diagonals.The truss can be used with Ground Support System with suitable sleeve blocksand towers.PRODUCTCODEB0600B0601B0602B0603B4600B4601B4602B4603B4604B4605B4608B46B4DESCRIPTION10' Section8' Section5' Section2' 6" Section3m Section2.5m Section2m Section1.5m Section1m Section0.5m Section4 Way Corner Block5 Way Corner Block6 Way Corner BlockWTlbs61.552.537.52461.5534237.528.519.522Allowable Load DataSpanfeet (meters)10 (3.048)20 (6.096)30 (9.144)40 (12.192)50 (15.24)Maximum Allowable Uniform LoadsLoadspounds (kgs)6140 (2785)3100 (1406)1726 (783)855 (388)425 (193)Maximum deflectioninches (mm)0.276 (7)1.10 (28)2.20 (56)2.95 (75)3.70 (94)Maximum Allowable Center Point LoadsLoadsMaximum deflectionpounds (kgs) inches (mm)4497 (2040) 0.20 (8)1550 (703) 1.10 (28)864 (392) 2.20 (56)427 (194) 2.95 (75)214 (97)3.70 (94)LOADING FIGURES show maximum loads between supports in addition to the self weight of the truss.
