2.3 Lifting the Display
Model DF-1030/DF-1040 displays are shipped equipped with 3 /
8
" eyebolts that are
used for lifting and positioning the modules. Eyebolts are located along the top outer
edges of the cabinet.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the
display. Using a spreader bar ensures that the force on the eyebolts is straight up,
minimizing lifting stress.
Figure 4 illustrates both the correct (left example) and the
incorrect (right example) method for lifting a display. Lift the display as shown on
the left, with a lifting bar. Be sure to use every lifting point provided.
Figure 4: Lifting the Display
Note: Daktronics assumes no liability for display damage or injury resulting
from incorrect setup or incorrect lifting methods.
Eyebolts are intended for lifting during installation only. Do not attempt to
permanently support the display by the eyebolts.
In installations in which an ad panel or some other display section may be added to
the base display, the lower section is installed first and secured to the support beams,
and then the upper section is placed atop or above the lower sign section and
attached to the beams. There may be cables extending from the top of the lower
section. Guide these cables into the hole in the bottom of the upper section for later
connection.
Installers may remove the lift eyebolts once the display is in place. If removing the
eyebolts, adequately seal the holes using bolts and sealing washers. In addition,
inspect the top and sides of the display for any holes or openings that may allow
moisture to enter the display, and plug and seal those openings with silicone.
