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 to
ED-7244 , Eyebolts , to determine allowable loads and load angles for the lifting
hardware. ED-7244 is located in Appendix B of this manual.
Avoid using other lifting methods. Cables and chains attached to the eyebolts and
directly to a center lifting point, as show in the right-hand example in
Figure 6 , can
create a dangerous lateral force on the eyebolts and may cause the eyebolts to fail.

aluminum plate or steel nut plate, but exceeding load angles or weight limits could
cause the bolts to pull out or cause the scoreboard cabinet to buckle. In either
circumstance, the result would be serious damage to the scoreboard. If using this
method, ensure a minimum angle of at least 45 degrees between the chain and
scoreboard.
Note: Daktronics assumes no liability for scoreboard damage resulting from
incorrect setup or incorrect lifting methods.
Eyebolts are intended for lifting only. Do not attempt to permanently support the
display by the eyebolts.
In typical multi-section installations, as with BA-2002, BA-2009 and BA-2018 the
lower scoreboard section is installed first and secured to the support beams, and then
the upper section is placed atop or above the lower section and attached to the
beams. There may be cables extending from the top of the lower section. Guide these
cables 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 sealing
washers that were removed with the eyebolts. Apply silicone or another waterproof
sealant to the eyebolt openings. Inspect the top and sides of the display for any other
holes or openings that may allow moisture to enter the display and plug and seal
those openings as well.

Models BA-2001, BA-2002, BA-2008, BA-2009 and 2018 are typically mounted in
one of two ways: permanently welded to tubular horizontal supports, or clamped to
vertical beams using mounting angles and long, threaded rods. The following
subsections describe both options.
