K1 — Flying an Array with K1-BUMP

Attaching K1-BUMP to a prepared block of four K1/K1-SB and raising the array off K1-CHARIOT. Reference: LA-K1-FLY-BUMP-01. Follow in order — this is a sequential rigging procedure, not an independent checklist; steps depend on the ones before them.

Rigging accessories: 4× 22 mm shackles WLL 3.25 t, K1-BUMP.
Minimum 3 operators.
Follow the same procedure for K1-SB enclosures.
Loudspeaker cable routing is not detailed here.
Prerequisite: prepare K1-BUMP; if necessary, secure LA-RAK II AVB on K1-BUMP; prepare a block of four K1; preset the inter-enclosure angles.

Flying an Array with K1-BUMP

Lift K1-BUMP to more than 2 m / 6.5 ft height using the motor. Position a block of four K1/K1-SB under K1-BUMP. Secure K1-BUMP on top of the array: on each side of the K1-BUMP rigging frame, remove the four ball-locking pins, lower K1-BUMP to facilitate the connection between the enclosures and the rigging frame, secure the front rigging arm using the K1-BUMP ball-locking pin, then rotate the rear rigging arm and secure it using the K1-BUMP ball-locking pin. Before raising the array, check that all ball-locking pins are fully inserted in rigging position and that all rear rigging arms are secured (no yellow sticker visible). Slightly raise the array to lock the inter-enclosure angles — the automatic locking system engages and the latches retract (except on the bottom enclosure) with an audible click per pair; confirm no yellow sticker is visible on the latches. Remove K1-CHARIOT from the array: holding K1-CHARIOT, remove the two front ball-locking pins and store them, then remove the two rear ball-locking pins and store them.
