J-Series Rigging manual

1. Safety precautions

1.1.

Intended use

The J-Series rigging components (Flying frame, Load adapter, Locking
pins) must only be used in conjunction with the d&b J-Series
loudspeakers J8, J12 and J-SUB as described in this manual.
Installation and set up should only be carried out by qualified and
authorized personnel observing the valid national Rules of Prevention of
Accident (RPA).
It is the responsibility of the person installing the assembly to ensure that
the suspension/fixing points are suitable for the intended use.
1.2.

Load capacity/System safety

The Z5300 J Flying frame is designed to suspend a total
system weight of 1.5 t (3300 lb) WLL (Working Load
Limit) according to BGV C1.
The rigging components allow arrays of up to 10 x J-TOP cabinets
(J8/J12) or a total system weight of 665 kg (1466 lb) to be flown in any
vertical splay angle configuration.

1.2.1. ArrayCalc / TI 385

For arrays with a total system weight of more than 665 kg (1466 lb) the
load conditions within the array have to be checked using the ArrayCalc
array calculator, which can be downloaded at www.dbaudio.com.
The use of ArrayCalc is described in "TI 385 J-, Q and T-Series system
design, d&b ArrayCalc" which is also supplied with the Z5300 J Flying
frame.
This TI includes typical array configurations within the permitted load
limits.
Carefully read this TI to become familiar with the operation and
behaviour of ArrayCalc and in particular with the mechanical load
conditions and limitations.
We also recommend to attend the regularly hosted d&b J-Series
training seminars. Further information of the d&b seminars can be
requested directly from d&b audiotechnik sales partners.
