WARNING: Due to the system-based design approach of the current RMI Specification, the use of static load capacities are no longer appropriate. Load ratings can only be provided through a system analysis which accounts for configuration of the system, static loading, seismic parameters, stability requirements and the interaction characteristics of the various system components. These capacity tables should only be used as a "starting point". . [Frame Options Options to secure your frames to the floor and/or add support](accessories/frame-options/) ## Slotted Beams easy assembly Ridg-U-Rak offers many standard beam profiles in virtually any length with capacities to 22,500 lbs. per pair. Beams have a safety factor of 1.67 based on minimum yield of steel. All beam capacities are calculated based on the requirements of the current RMI specification. All capacities are based on uniformly distributed loads on a pair of beams. Other loading conditions can greatly reduce the carrying capacity of a beam. For unusual loading requirements, call your local Ridg-U-Rak distributor. - Offset anchor holes - Full array of profiles to optimize the solution - 2" vertical adjustability - Large base plates - 6 bend column - 100% welded uprights #### Beam Capacities Beam Profile Beam Lengths 48" 60" 72" 84" 92" 96" 102" 108" 120" 144" 156" 250 S 5,700 4,530 3,130 2,300 1,910 1,750 1,550 1,380 1,120 770 660 300 S 7,500 5,980 4,820 3,530 2,940 2,690 2,380 2,120 1,720 1,190 1,010 355 S 9,760* 7,770 6,460 5,330 4,440 4,070 3,600 3,210 2,590 1,790 1,520 410 L 10,810* 8,620 7,150 6,110 5,570 5,200 4,600 4,100 3,310 2,290 1,940 410 S 12,270* 9,780* 8,120 6,930 6,320 5,830 5,160 4,600 3,710 2,570 2,180 465 S 15,020* 11,970* 9,940* 8,490 7,740 7,410 6,960 6,320 5,110 3,530 3,000 500 S 16,890* 13,460* 11,170* 9,540* 8,700 8,330 7,830 7,380 6,140 4,250 3,610 550 S 19,720* 15,710* 13,050* 11,150* 10,160* 9,720* 9,140* 8,620 7,740 5,420 4,610 600 S 22,500* 18,120* 15,050* 12,850* 11,710* 11,210* 10,540* 9,940* 8,920 6,790 5,770 650 S 22,500* 20,670* 17,160* 14,660* 13,360* 12,790* 12,020* 11,340* 10,180* 8,360 7,110 650 R 22,500* 22,500* 19,480* 16,640* 15,160* 14,520* 13,640* 12,870* 11,550* 9,370* 7,970 • Capacities marked with * indicate that the column connection capacity may be limited based on the hook option and/or frame model (see table below). • Capacities listed are for non-seismic conditions. For seismic conditions consult with Ridg-U-Rak sales or engineering. • Capacities are based on uniformly distributed loads per pair of beams. • Capacities listed are for a 2-pallet wide condition. • All beams over 114" in length should utilize at least one flanged, tek-screwed or lock-in cross bar located at mid length.
