8 Mechanical Installation
3.2 Four-Sided Scoreboard Suspension Options
The method by which the scoreboard is to be suspended must be determined at the time of
purchase. There are two primary methods of installing a center-hung scoreboard: creating a
static-hung system or using a hoist. Each method has its own benefits and drawbacks. Refer
to the suspension publication,
DD1627665 , in Appendix F , and call Daktronics for help in
making the best choice for your installation.
Note: Do not attach items to the scoreboard without prior approval.
To properly review and approve a proposed attachment, Daktronics requires information on
the size, weight, and method by which the item will be attached to the scoreboard.
(Engineering time to review attachments will be charged at a "time and expenses" rate.)
Static Mounting
Static-mounted displays are typically hung with two or four static cables. Two cables may be
used when mounting the scoreboard below a large beam or when the display is centered
between a pair of beams. Four cables are used to further distribute weight.
Note: For either method, the mounting cables must be symmetrically distributed to
maintain a level and a square configuration.
Cable assemblies must have a strength greater than six times the actual load. All other rigging
components must be sized within the working load limits published by the component
manufacturer.
Note: Daktronics strongly recommends that only components from reputable domestic
suppliers be used to permanently suspend the scoreboard.
Remove immediately and do not use any assemblies that show evidence of excessive wear or
broken wires as defined by the component manufacturer.
Follow these procedures for installation:
1. Have a structural engineer certify that the building can safely support the additional
display loading and that the connection points are designed to safely carry the
scoreboard weight.
2. Attach the cable sling to the scoreboard assembly while it is on the arena floor.
3. Hang ends that attach to the ceiling over the sides of the scoreboards. If an end is too
short, attach a rope to the end temporarily so it can be returned from the top.
4. The scoreboard can be lifted into place in a number of different ways.
Note: It is the installer's responsibility to ensure that the installation is safe and that
the display meets OSHA or local regulations.
