3.1 Scoreboard Protective Devices
Note: Some owners install devices to protect the display from projectiles . Daktronics
must approve scoreboard protection devices not provided by Daktronics prior to
installation. Failure to follow this approval procedure will void the scoreboard
warranty.
Daktronics makes optional devices available, including screens and netting, to help
protect the scoreboard from damage due to normal ball impact.
3.2 Lifting the Scoreboard
Reference Drawing:
Lifting Scoreboard.......................................................... Drawing A-44548
Larger Daktronics displays like the Model TN-2018, TN-2029, TN-2032, TN-2037
and TN-2042 tennis scoreboard are shipped equipped with eyebolts that are used for
lifting, two for each section of the display. The eyebolts are located along the top of
the cabinet of 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 following illustration,
Figure 3 , and in Drawing A-44548 .
The drawing 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.
