Lifting Scoreboard .........................................................
Drawing A-44548
Small Daktronics scoreboards are not equipped with eyebolts. Refer to
Drawing
A-44548
for lifting detail
Larger 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.
Note:
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the
display.
Figure 3: Lifting the Display
Using a spreader bar ensures that the force on the eyebolts is straight up, minimizing
lifting stress. Lifting methods are shown in
Figure 3
and in
Drawing A-44548
.
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 not to exceed the rated load of the eyebolts. 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 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

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, there could 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°.
