A hollow structural section column designated as HSS 7x7x3/8 anchors the jib crane column connection assembly. A top knife plate measuring 3/8 inch by 8 inches by 8 inches is welded to the column end with 1/4-inch fillet welds on each side. Typical WT6x17.5 structural tees measuring 1 foot 0 inches in length provide intermediate support and connect to the hollow structural section column using 1/4-inch fillet welds. Plates measuring 3/8 inch thick by 6 inches by the flange width are welded top and bottom to the structural tees with 1/4-inch fillet welds. The jib crane bracket and connection are mounted per the manufacturer specifications, with vertical dimensions verified with the crane manufacturer.
