The TFS-DOLLY wheelboards can be stacked using the woodwork rebates provided Fold the TFS-COVERS and
stack them on top of the wheelboards.

7.4 De-rigging the Array

Taking the cluster down is a simple reversal of the rigging procedure. Bring the cluster down until the bottom
box is approximately a foot off the ground, and take the lock pins out at the front of the lowest four or more
boxes (depending on the curvature of the array) to allow the cabinets to close up, and place them in the stow
position. Lower the back motor gently to get the bottom box reasonably horizontal.
Make sure you always know the total weight of the
cluster. Never put more weight on a rigging point
than it is rated for, and always calculate how much
weight is on each rigging point.
Carefully lower the cluster down onto a TFS-DOLLY. Disconnect the top pins from the fourth box.
Carefully raise the array to free the lower four boxes.
Ensure the drop link of the bottom box is up and into its locked position. Do not land the cluster on the drop
link or you will bend the rear hinge. Do not leave the front lock pins in for trucking, always put them in the store
position.
Leave both pins in on the rear assembly because it is designed to allow the cabinets to touch each other in a
truck rather than the rigging hardware.
Having de-rigged each block of cabinets onto a TFS-DOLLY one by one, put the covers on and stow the NL8
links in the cover.
Finally lower the TFS-GRID flybar into the TFS-FT900 flytrunk in, disconnect the motors and lift the motors to a
safe position above head height.
Stow the shackles in the trunk, slide the TFS-TIP tipper bar out, put the bolts back in the trunk and replace the
tipper bar in its stowed location.
