Daktronics TN-2501 Tuff Sport Indoor LED Tennis Scoreboard - Manual (Page 9)

Mechanical Installation 3
Section 2: Mechanical Installation
Mechanical installation consists of lifting and permanently mounting the scoreboard, statistics panels,
and game/shot clocks. The product specification sheets listed in Appendix A include installation
specification drawings that show the recommended number and spacing of wall anchors for specific
scoreboard models.
Be sure that the installation complies with local building codes.
Note: Daktronics does not assume any liability for any installation derived from the information
provided in this manual or installations designed and installed by others.
2.1 Lifting the Scoreboard
Daktronics Tuff Sport tennis scoreboards are shipped equipped with at least one eyebolt
for lifting, as well as pre-drilled holes along the top and bottom of each cabinet for wall
attachment. Eyebolts are located along the top of the cabinet for each scoreboard or
scoreboard section. Daktronics indoor scoreboards use
3 /
8
" eyebolts.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the display.
Spreader bars ensure the force on the eyebolts remains straight up, minimizing lifting stress.
Figure 3 illustrates the preferred scoreboard lifting method on the left and an acceptable
alternative lifting method on the right. When lifting the display:
 Use a spreader bar if possible.
 Use every lifting point provided.
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. The smaller the angle between the cable and the top of the
display, the lighter the sign must be to safely lift it. If this method must be used, ensure a
minimum angle between the chain and scoreboard of at least 45°.
Do NOT attempt to lift the display if the angle is less than 45°.
