Rigging WPM with the WPMGRIDi Install Flying Frame - Single Box Method

WPM cabinets can also be flown one at a time to form an array in a permanent installation. In this case the cabinets are
prepared, and inter-cabinet angles preselected, individually according to the Martin Audio DISPLAY software prediction.
The following example illustrates the procedure for rigging an array of eight WPM cabinets one at a time with the install Flying
Frame:
” 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 first box and attach it to the front rigging points by inserting a
Rigging Pin at each side. Attach the flybar rear drop link to the box at the (bar) position.
” Attach a chain motor(s) to the shackle(s), and raise the first cabinet to allow a second cabinet to be positioned face down
underneath.
” Release the drop link on the first cabinet and line it up with the rear rigging spine on the second cabinet at the angle position
predicted by the DISPLAY software. Secure with a Rigging Pin.
” Rotate the second box upwards to engage with the front rigging points, and secure with a Rigging Pin at each side.

” Raise the array and position a third cabinet underneath. Release the drop link on the second cabinet and line it up with the
rear rigging spine on the second cabinet at the angle position predicted by the DISPLAY software. Secure with a Rigging
Pin, rotate the third box upwards to engage the front rigging points, and secure with a Rigging Pin at each side.
