2.1.2. Z5387.001 Vi Mounting frame bottom
Intended use
The Z5387.001 Vi Mounting frame bottom is designed as a
pullback device to fix and/or pull back an array with either the
Z5387.000 Vi Mounting frame top or the Z5380 V Flying frame
mounted on top of the array.
Alternatively, the frame can be used as an adapter frame to be
attached underneath SUB cabinets in mixed array configurations
with the Z5380 V Flying frame mounted on top of the array. This
allows a maximum of up to 4 x Vi-TOP cabinets to be attached
underneath SUB cabinets.
Note: A detailed description of the Z5380 V Flying frame
including the relevant assembly instructions is given in the V-
Series Rigging manual, which is supplied with the V Flying
frame.
NOTICE!
Construction notes
Each side of the tie bar at the front end of the frame is equipped
with a Front link. Both Front links are undetachably attached to the
tie bar using a fixing bolt. Directly above each of these fixing bolts
there is a Locking pin that serves to additionally stabilize the Front
link in its recess. For safety reasons, this Locking pin must always
be inserted and locked.
In addition, there is a second Locking pin on each side of the tie
bar which is used to connect the frame with a cabinet.
