Whenever possible, use a spreader bar, or lifting bar, to lift the cabinet. Spreader bars
ensure force on the eyebolts remains straight up, minimizing lifting stress.
illustrates the preferred lifting method on the left and an acceptable alternative
lifting method on the right. When lifting the cabinet:
• 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
"Acceptable" example in
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 cabinet,
the lighter the cabinet must be to safely lift it. If this
method must be used, ensure a minimum angle
between the chain and cabinet of at least 45°.
Do NOT attempt to lift the cabinet if the angle is
less than 45°. Exceeding load angles or weight limits
could cause the bolts in the cabinet to buckle,
resulting in serious damage to the equipment or injury
to personnel. Also, loads should be applied directly in
the plane of the eyebolt as shown in
.
Note:
Daktronics assumes no liability for damages resulting from incorrect setup or lifting
methods. Eyebolts are intended for lifting only. Do not attempt to permanently
support the cabinet by the eyebolts or eyebolt holes.
If installers remove the eyebolts, use 5/8" bolts to plug the holes.
Mount the Cabinet
Reference Drawings:
Shop Drawing; Sound System; 2000HD ............................................................
DWG-330901
The sound cabinet will be mounted atop a frame that must be certified by a structural
engineer. To mount the system in place, position the cabinet on the structure where it
is to be mounted. Weld the cabinet’s bottom members to the structure at the locations
indicated on the shop drawing. Refer to
DWG-330901
in
Appendix A
for mounting
requirements.
