Rigging WPM with the WPMGRIDi Install Flying Frame

The procedure for flying a permanently installed system of WPM cabinets is practically identical to that for touring applications;
the only difference being that this method uses the simplified install Flying Frame with either one or two pickup points. It is
recommended that the cabinets are prepared and assembled face down in blocks of four with angles preselected according to
the Martin Audio DISPLAY software.
The following example illustrates the procedure for rigging an array of eight WPM cabinets with the install Flying Frame:
” To pre-select the inter-cabinet angles release the drop link from the first box by removing the Rigging Pin from the LOCK
position. Slide it down and engage it with the appropriate angle hole in the second box as predicted by the DISPLAY
software, securing it with a Rigging Pin.
” Continue to preselect the inter-cabinet angles on the remaining three cabinets according to the DISPLAY software
prediction.
” Attach shackles to the front and rear lift points of the flybar. If using only one pickup point attach a shackle to the pickup hole
predicted by the DISPLAY software. Offer the flybar up to the top box and attach it to the front rigging points by inserting a
Rigging Pin at each side. Attach the flybar rear link to the top box at the (bar) position.
” Attach a chain motor(s) to the shackle(s), and raise the first block of four cabinets to a convenient working height allowing
sufficient space underneath for a further block of cabinets.
” Position the next block of cabinets underneath the array, having first preselected the inter-cabinet angles as before
according the DISPLAY software prediction
” Release the drop link on the fourth cabinet and line it up with the rear rigging spine on the fifth cabinet at the angle position
predicted by the DISPLAY software. Secure with a Rigging Pin.
