3-4 Mechanical Installation• Use a spreader bar.• Use every lifting point provided.Take special care to ensure the rated load of the eyebolts is not exceeded. Refer toED-7244, Eyebolts, to determine allowable loads and load angles for the liftinghardware. ED-7244 is located in Appendix B of this manual.Avoid using other lifting methods. Cables and chains attached to the eyebolts anddirectly to a center lifting point, as show in the right-hand example in Figure 6, cancreate a dangerous lateral force on the eyebolts and may cause the eyebolts to fail.Daktronics scoreboards use 1/2" and 5/8" shoulder-type eyebolts mounted to a 1/8"aluminum plate or steel nut plate, but exceeding load angles or weight limits couldcause the bolts to pull out or cause the scoreboard cabinet to buckle. In eithercircumstance, the result would be serious damage to the scoreboard. If using thismethod, ensure a minimum angle of at least 45 degrees between the chain andscoreboard.Note: Daktronics assumes no liability for scoreboard damage resulting fromincorrect setup or incorrect lifting methods.Eyebolts are intended for lifting only. Do not attempt to permanently support thedisplay by the eyebolts.In typical multi-section installations, as with BA-2002, BA-2009 and BA-2018 thelower scoreboard section is installed first and secured to the support beams, and thenthe upper section is placed atop or above the lower section and attached to thebeams. There may be cables extending from the top of the lower section. Guide thesecables into the hole in the bottom of the upper section for later connection.If the lift eyebolts are removed, plug the holes with bolts and the rubber sealingwashers that were removed with the eyebolts. Apply silicone or another waterproofsealant to the eyebolt openings. Inspect the top and sides of the display for any otherholes or openings that may allow moisture to enter the display and plug and sealthose openings as well.3.5 Scoreboard MountingReference Drawings:Steel Clip Angle Mounting .............................................

Drawing A-89234Models BA-2001, BA-2002, BA-2008, BA-2009 and 2018 are typically mounted inone of two ways: permanently welded to tubular horizontal supports, or clamped tovertical beams using mounting angles and long, threaded rods. The followingsubsections describe both options.
