size of beams required to support the scoreboard at different heights and under
various wind speed conditions. All of the beam specifications illustrate W-shape
steel beams (wide-flange I-beams). The first number indicates the front-to-rear depth
of the beam and the second number indicates the weight in pounds per foot of
length.
The column and footing size dimensions provided assist with estimating installation
costs. They are estimates only and are not intended for construction purposes. Be
sure that the installation complies with local building codes and is suitable for the
particular soil and wind conditions.
The columns, footings and all connection details must be designed and certified by a
professional engineer licensed to practice in the state in which the scoreboard will be
installed.
Note:
Daktronics does not assume any liability for any installation derived from the

Lifting the Scoreboard

Drawing A-58668
Small Daktronics scoreboards are not equipped with eyebolts. Refer to
Drawing
A-58668
for lifting details.
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.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift 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
.
