The safety factor is the result of the forces acting on fly bar’s and system’s front and rear
links and pins and depends on many variables:
- number of cabinets;
- fly bar angles;
- angles from cabinets to cabinets. If one of the cited variables change the safety factor
MUST BE recalculated using the software before rigging the system.
In case the fly bar is picked up from 2 motors make sure that the fly bar angle is correct. An
angle different from the angle used in the prediction software can be potentially dangerous.
Never allow persons to stay or pass under the system during the installation process.
When the fly bar is particularly tilted or the array is very curved the centre of gravity can
move out from the rear links. In this case the front links are in compression and the rear
links are supporting the total weight of the system plus the front compression. Always
check very carefully with the “RCF Shape Designer” software all this kind of situations
(even with a small number of cabinets).

THE HDL FLY BAR FEATURES:
FRONT FLYING BRACKET. Front mounting.
QUICK LOCK PIN HOLE. Front mounting (to be used to lock the front bracket before

FRONT BRACKET - TRANSPORT HOLES.
CENTRAL PICK UP POINTS.
The pickup is asymmetric and can be fit in two positions (A and B). A position brings the
shackle towards the front. B position allows an intermediate step using the same fixing holes.
