Daktronics BA-1518 - Manual (Page 30)

Mechanical Installation 6-3
Take special care to ensure the rated load of the eyebolts is not exceeded. Refer to ED7244, Eyebolts,
to determine allowable loads and load angles for the lifting hardware. ED7244 is located in Appendix
B in 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 2, can create 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
could cause the bolts to pull out or the scoreboard cabinet to buckle. In either circumstance, the result
would be serious damage to the scoreboard. If you must use this method, ensure a minimum angle
between the chain and scoreboard of at least 45°.

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, the lower scoreboard section is installed first and secured to the
support beams. The upper section is then 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.

Scoreboards can be mounted on two, three, or four poles. Refer to Section 6.1 to determine the center-
to-center distance of the poles for each model.
Drawing A-44412 shows the hardware used for mounting the scoreboard to the beams. Each section of
the scoreboard attaches at the top and the bottom to all the beams. Drawing A-44412 also shows top
and side views of the scoreboard secured to the beams. Note that the threaded rods do not pass through
the flanges of the beams, but instead run along both sides of each beam
