L2 — Adding a Pullback L2-RIGBAR

Adding an L2-RIGBAR pullback to the bottom of a completed, flown array — typically to set the angle of a horizontal array. Reference: LA-L2-PULLBACK-01. Follow in order — this is a sequential rigging procedure, not an independent checklist; steps depend on the ones before them.

Safety notes

Minimum 2 operators. Rigging accessories: L2-RIGBAR, 2 Ø19 mm shackles WLL 3.25 t.
Do not raise the rear pickup point above the front pickup point — pickup points must stay aligned with the linking points.
The pullback chains must be as vertical as possible.

Prerequisite

The array is completed and secured under L2-BUMP with L2-BAR, or under another L2-RIGBAR. See Flying with L2-BUMP and L2-BAR or Flying with L2-RIGBAR.

Rigging the Pullback

Secure L2-RIGBAR on the bottom enclosure using the ball-locking pins. Secure a Ø19 mm shackle WLL 3.25 t to L2-RIGBAR and lift with an additional motor. Adjust the height of the pickup points, keeping the pullback chains as vertical as possible and the rear pickup point no higher than the front.
