1. Carefully uncrate the display. Look each side of the display over for possible damage during shipping. 2. Following the guidelines described in Section 2.4, lift the display into position on the support structure. 3. Weld or use ½" Grade-5 bolts and hardware to secure the clip angles to the support structure as shown in Drawing B-172745 or B-172746. - Page 19 Eyebolts Almost every display that leaves Daktronics is equipped with eyebolts for lifting the display. There are two standard sizes of eyebolts: ½″ and A″. Load Increase Factor: The load increases as the lift angle (θ) decreases. The allowable load on the eyebolts also decreases with the lift angle due the bending stress on the eyebolts.
- Page 20 F. Eyebolts should never be painted or otherwise coated when used for lifting. Such coatings may cover potential flaws in the eyebolt. G. To attain the safe working loads listed for regular eyebolts, 90% of the thread length must be engaged. Copyright 1996-2001 ED-7244 Daktronics, Inc. Rev. 4 – 14 March 2001...
