Figure 2: Lifting the Scoreboard
Figure 2
above 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
ED-7244 , Eyebolts , to determine allowable loads and load angles for the lifting
hardware. ED-7244 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 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

" 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, 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.
