6.3 Lifting the Scoreboard
Reference Drawings:
Lifting Scoreboard................................................................................. Drawing A-44548
Large scoreboard sections and message centers are shipped equipped with eyebolts that are used to
lift the displays. The eyebolts are located along the top of the cabinet for each scoreboard or
scoreboard section.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the display. Using a
spreader bar ensures that the force on the lifting straps or eyebolts is straight up, minimizing lifting
stress. Lifting methods are shown in the illustration below, Figure 3, and in Drawing A-44548.
Figure 3: Lifting the Display
Figure 3 illustrates both the preferred method (left example) and an alternative method (right
example) for lifting a scoreboard. When lifting the display:
+ 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 ED7244:
Eyebolts, to determine allowable loads and load angles for the lifting hardware. ED7244 is located in
the Appendix of this manual.
Avoid using other lifting methods. Cables and chains attached to the eyebolts and directly to a center
lifting point, as shown in the right-hand example in Figure 3, 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°.
K 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.
