JAMESENGINEERINGSUPERTRUSS12 x 12The revolutionary truss designed to offer all the advantages of the 20.5" Supertruss in a12" x 12" layout. The 12" x 12" Supertruss provides a substantial increase in load bearing capacityover the existing GP 12" x 12" truss. The main chords of the truss are made from 2" x 0.157"6061-T6, and the diagonals are 1" x 0.125".PRODUCTCODEB1260AB1261B1262B1263B1264B1265B1200AB1201B1203B1204AB1204BB1208B1211G6671ADESCRIPTION12' Section10' Section8' Section6' Section5' Section2' 6" Section60 Degree corner gate90 Degree corner gate135 Degree corner gate3 Way gate/ 120 0 gate3 Way gate with lifting pointSquare support plate12" Super-truss toGP 12" x 12" adaptor gate12" Supertruss pinextraction toolWTlbs877267514227148588477Allowable Load DataSpanfeet (meters)10 (3.048)20 (6.096)30 (9.144)40 (12.192)50 (15.24)Maximum Allowable Uniform LoadsLoadspounds (kgs)8496 (3854)*7255 (3291)3324(1508)1695 (769)888 (403)Maximum deflectioninches (mm)0.20 (5)1.50 (38)2.20 (56)2.95 (75)3.70 (94)Maximum Allowable Center Point LoadsLoadspounds (kgs)7348 (3333)3628 (1646)1662 (754)848 (385)445 (202)Maximum deflectioninches (mm)0.20 (5)1.50 (38)2.20 (56)2.95 (75)3.70 (94)LOADING FIGURES show maximum loads between supports in addition to self weight of truss.
