exceeding load angles or weight limits could cause the bolts to pull out of the scoreboard
cabinet to buckle. In either circumstance, there could be serious damage to the scoreboard.
If this method is used, ensure a minimum angle between the chain and scoreboard of at least
45 degrees.
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 installations in which an ad panel or some other scoreboard section may be added to the
base display, 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 installers remove the lift eyebolts, plug the holes with bolts and the rubber sealing washers
used 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.
