Suspending the WideLine-8 Array
Pull-Back Bar
To use the pull-back bar, attach it to the bottom enclosure’s suspension
plates using one of the lower sets of splay angle adjustment holes.
Align the pull-back bar’s holes with the suspension plate’s and fully
insert the ball-lock pins. Ensure locking action of pins. Use a 5/8” (16
mm) screw-pin anchor shackle to attach to the pull-back bar as required
using the shackle holes.
NOTE: All hardware/components must be rated for the
expected loads as determined by the Professional Engineer
responsible for suspension.
NOTE: The PB3082 can also be used to suspend small arrays
of WL3082 enclosures. See page 10 for detailed information.
Extension Bar
The extension bar suspension plates can be moved, if required, by
removing the two 3/4”mounting bolts, moving to the selected mounting
location, and reattaching. Tightening torque is to be 100 lb-ft of torque
(135.6 N-m) Ease-Focus software’s center-of-gravity calculator will pro-
vide a suitable point for desired down-tilt.
Attach the array frame to the extension bar suspension plates by
centering the array frame member between the extension bar sus-
pension plates and bolting together using the supplied 3/4” bolts.
