If space permits, prepare the flown Flashlight high boxes by wheeling them into
position, in two rows six across, behind the flybar position. In this particular
configuration TFS-780HF long-throw mid-high boxes will form the top row of each
column, and for convenience these can be stacked on top of the first row of Flashlights
and wheeled in together. Loosen the camlocks securing the wheelboards to the
underside of the Flashlight cabinets, so that when the cabinets are hoisted the
wheelboards will remain on the ground. Open the access door of each cabinet, take out
the biscuit and allow this to hang outside the box on the captive string. It is better to
leave the EP6 cable inside for now, because once connected later on they should be
stowed inside the box to eliminate any possibility of becoming disconnected.

Attach chain motors to the three fly bar
lifting points with shackles and secure
them. Attach safeties if required. The
flybar assembly is now ready be hoisted
to accept the first row of cabinets. Attach
two 1 metre spansets to the cable drop
points on the flybars with shackles to act
as cable strain reliefs. It is a good idea to
have the bulk of the cables tied directly to
the bar as opposed to hanging below it –
in this way their weight is less likely interfere with the column’s centre of gravity. Raise
the flybar to about shoulder height, ensure that it is is level, and once more check the
horizontal coverage. Make any final adjustments to the flypoints now, if required, as the
weight of the flybars is not excessive and it is quite easy to lift the flybar, taking the load
off the chains as they are moved. A couple of inches forward or backwards may make a
significant difference to the way system hangs, so take time to get this right.
5.
Attach flying chains to each of the single
bars. The chains are colour coded blue
for left, red for right, looking at the
enclosures from the front. It is a good
idea to count out and hang or lay the
correct number of flying chains out
beforehand in an easily accessible place –
such as on the edge of a fly bar trunk -
according to their colour: reds together
and blues together. This is a good
opportunity to remove links from the clutch and check their condition. All the hooks
should point outwards from the boxes, with the clutch facing to the front, since this
makes it easier to de-rig later on. This orientation is preferred because if during rigging
or de-rigging the box should come up and into contact with the hook, there is no
