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

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.

J-Series Rigging manual (1.3 EN) Safety precautions - 1/Page 4 of 34

1.3. Operational safety

During assembly pay attention to the possible risk of crushing hazard.
Wear suitable protective clothing.

Observe the weight of the J-Series loudspeaker cabinets and the J
Flying frame. Single person lift could cause injury – Lifting Hazard!
Always use assistance when moving or lifting.

Observe all instructions given on the rigging components (Flying frame,
Load adapter) and the loudspeaker cabinets.

When chain hoists are in operation ensure that there is nobody directly
underneath or in the proximity of the load.

Under no circumstances climb on the array.

3. Preparation

3.1. General preparations

Check the acoustical and mechanical set up with the ArrayCalc array
calculator and prepare enough print outs for each array.

Using the plan, the riggers are able to set up the suspension points, the
securing points and the chain hoists.

The working load limit of the chain hoists and their
suspension points has to be high enough to carry the
total system weight.

As during a dual hoist set up the motors might not
always be synchronized each of the suspension points
has to be able to carry the total system weight.

When on site first clear the working areas, check that the hoists are
exactly in the specified position, the chains are not twisted and there is
enough space to set up and lift the array.

3.2. Inspections

All system components must be inspected for faults before use. This also
includes the loudspeaker and in particular the rigging parts of the
cabinets.

WARNING!

Fig. 10: J-Series Locking pins, Quicklock

Damaged components must be withdrawn from use immediately. Please
pay attention to section 6. Care and maintenance / Disposal on page
31 of this manual.

3.3. J-Series Locking pins

The steel wire between the locking pins is not meant to
suspend a cabinet or carry any load. The cabinet's weight
must only be carried by the Front and Splay links in
conjunction with front and rear rigging strands of the
loudspeaker cabinets

Assembly

1. Pressing the button [B] releases the locking mechanism allowing

insertion through the respective links or sockets.

2. Releasing the button after the pin is inserted and fixed in place the

locking mechanism will be locked. A groove [G] (Fig. 10) in the bolt
of the pin indicates that it is properly locked.
