Daktronics BA-515 - Manual (Page 24)

The columns and footings and all connection details must be designed and certified by a professional
engineer licensed to practice in the state in which scoreboard will be installed. Daktronics does not
assume any liability for any installation derived from the information and drawings provided in this
manual or designed and installed by others.
6.2 Lifting the Scoreboard
Reference Drawings:
Lifting Scoreboard................................................................................... Drawing A-44548
Lifting Small Baseball 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 the illustration below and in Drawing A-44548.
Figure 3: Lifting the Display
Figure 3 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 3, can create a dangerous lateral force on
the eyebolts and may cause the eyebolts to fail. Daktronics scoreboards use
