JAMESHD 20.5 x 30ENGINEERING20.5" x 30" truss is for those ever increasing load requirement situations. The truss is connectedtogether with bolts as standard and can be used with a Ground Support System by using suitable SleeveBlocks and Towers. This truss can also be specified with castor wheels. The main chords of the truss aremade from 2" x 0.157"and the diagonals are 1" x 0.125". Aluminum Alloys are either 6061T6 or 6082T6.PRODUCTCODEB0900B0901B0902B4900B4901B4902B4903B4904B4905B4906B4907B4908PRODUCTCODEB0920B0921B0922B4920B4921B4922B4923B4924B4925DESCRIPTION10' section8' section5' section4m section3m section2.5m section2m section1.5m section1m section2 way corner block3 way corner block4 way corner blockTRUSS WITH CASTORS10' section8' section5' section4m section3m section2.5m section2m section1.5m section1m sectionWTlbs79.572.566105.579.573.56660533537.540WTlbs979083.5123.5979183.57770.5Allowable Load DataSpanfeet (meters)10 (3.048)20 (6.096)30 (9.144)40 (12.192)50 (15.24)60 (18.29)70 (21.34)Maximum Allowable Uniform LoadsLoadspounds (kgs)5646 (2561)*5646 (2561)*5562(2523)*4127 (1872)3150 (1429)2460 (1116)1953 (886)Maximum deflectioninches (mm)0.236 (6)0.236 (6)0.709 (18)1.65 (42)2.05 (52)2.80 (71)3.66 (93)Maximum Allowable Center Point LoadsLoadspounds (kgs)5646 (2561)*5646 (2561)*4202 (1906)2063 (936)1574 (714)1230 (558)976 (443)Maximum deflectioninches (mm)0.315 (8)0.315 (8)0.709 (18)1.65 (42)2.05 (52)2.80 (71)3.66 (93)LOADING FIGURES show maximum loads between supports in addition to self weight of truss.
