Daktronics BB-2102 Tuff Sport Four-Sided Basketball LED Scoreboard - Manual (Page 15)

Mechanical Installation 9
Lifting Method Example: A common method of temporarily lifting the scoreboard is to use a
pair of chain-lift motors mounted on the ceiling. Secure prior approval from the facility
management regarding location and acceptable loads for each rigging point.
1. Attach the chain hoist hooks to the sling master link, or sling to the corner lift tubes.
Be sure the angle of the sling is greater than 45°.
2. Use the chain hoist to lift the scoreboard to the appropriate height.
3. From the lift, retrieve the sling cables draped over the sides of the scoreboard and
attach them to the appropriate locations in the ceiling.
4. Connect to power outlets (and signal junction boxes, if required) in the ceiling.
5. Level the scoreboard by adjusting the turnbuckle on the sling.
6. Lower the scoreboard weight onto the slings.
7. Remove the chain motors.
Electric Hoist System
Installing an electric hoist system is more complex and may expose the customer to greater
liability. Publication SL-03610 in Appendix F discusses recommended minimum hoist
specifications and points that must be considered when selecting a hoist system.
 A building engineer must review and approve the combined weight of the
scoreboard, hoist, and a minimum impact factor of 15 percent.
 The hoist must be accessible for periodic inspections and maintenance as required by
ANSI and OSHA.
Note: Records of periodic inspections must be on file to be accessible for OSHA
(refer to Section ‎5.7).
 Electrical service and control wiring must be run to the hoist location.
 Additional structures in the ceiling are often required to accommodate the hoist.
 If an existing hoist is to be used, or if a hoist is to be purchased directly by the end
user, the user assumes all responsibility and liability for the hoist system.
 The hoist must be inspected and certified in writing by the hoist manufacturer,
manufacturer's representative, or other qualified hoist inspector.
 Daktronics will inspect hoists installed by Daktronics.
 Daktronics will certify the scoreboard weight but will require a liability waiver
signed by the customer before the scoreboard is shipped.
 Once the hoist is installed according to the specifications of the hoist manufacturer
and the building engineer, refer to Section ‎3.10 for more information about attaching
the scoreboard to the hoist.
WARNING!
 Never ride in or work on or below the scoreboard while the hoist is powered up.
Daktronics recommends having an audible horn warning to indicate that the hoist
system is ON.
 Never operate the hoist system during public events or when people are below the
scoreboard.
 When running the hoist, the operator must have an unobstructed view from ceiling to
floor (to ensure free scoreboard travel). Hoist operators should be trained according
to the hoist manufacturer's specifications.
