Mechanical Installation 3
Section 2: Mechanical Installation
Mechanical installation consists of installing concrete footing and steel beams and mounting the
scoreboard and accompanying ad panels to the beams. Refer to site-specific diagrams for proper
placement and mounting method of display pieces. These drawings may be requested from a
Daktronics sales coordinator or project manager.
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 of the scoreboard installation.
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
Larger scoreboard sections and message centers are shipped equipped with eyebolts used to
lift them. The eyebolts are located along the top of the cabinet for each scoreboard or
scoreboard section. Daktronics scoreboards use
1 /
2
" and 5 /
8
" shoulder-type eyebolts mounted
to the top of each scoreboard section.
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°.
