CRA30 flown array assembling

The numbers in the text below, correspond with the CRA30 overview pictured earlier.

The CRA30 system can be flown from a cinema screen frame or Truss. This is an optional set-up. It is intended for

indoor use only.

The system is scalable with 1x CRA30W + 1x CRA30N or 1x CRA30W + 2x CRA30N

It is not possible to attach 2x CRA30W to each other.

Mount two FLSTRPCRA30 strips (9) at both sides of the CRA30N (outermost holes) and W cabinet (inner holes).

They can be screwed in place with two M8x45 screws. Attach two HSTBRCRA30 hoist-bars (8) onto the top

CRA30N cabinet with M10x16 screws. The bar also fits on a CRA30W. The Hoist bar has 23x 14mm/0.55-in holes for

1,5T shackles. Use two hoists to raise the array. Use two steels/ chains on both hoist-bars for a stable hang and easy

array-angling

Attach the front couplers (5) and the angle arms (4) on the top side of an underhung CRA30N or W cabinet. Use the

supplied M10 screws. They have a 8.8 strength class with a max. thread length of 16mm/ 0.63"

Make the angle arm connection, with the correct angle adjustment.

Repeat this mounting procedure with an optional third CRA30 cabinet. Tighten up all front coupler and angle arm

screws. Connect all cabling to the signal input panels (6) and ensure that the cable weight is supported by a

dedicated cable suspension.

Hoist the completed array to the correct height and angle the array to the correct array tilt
