Flown congurations
The 5XT rigging system complies with 2006/42/EC: Machinery Directive. It has been designed following the guidelines
of BGV-C1.
2006/42/EC: Machinery Directive species a safety factor of 4 against the rupture. The own deployments described in
this manual achieve a safety factor of 5 or more.
The safe limit gives the maximum number of elements for which the safety factor is compliant with the 2006/42/
EC: Machinery Directive, within the use dened in this manual and regardless of the other deployment parameters (site
angles, inter-enclosure angles, etc.).
The maximum limit gives the maximum number of elements for which the safety factor can be compliant with the
2006/42/EC: Machinery Directive, when the other deployment parameters provide the best mechanical conditions.

Assessing mechanical safety
Mechanical safety of the rigging system
Before any installation, always model the system in Soundvision and check the Mechanical Data section for
any stress warning or stability warning.
In order to assess the actual safety of any array conguration before implementation, refer to the following warnings:
Rated working load limit (WLL) is not enough
The rated WLL is an indication of the element resistance to tensile stress. For complex mechanical systems such as
loudspeaker arrays, WLLs cannot be used per se to determine the maximum number of enclosures within an array
or to assess the safety of a specic array conguration.
Mechanical modeling with Soundvision
The working load applied to each linking point, along with the corresponding safety factor, will depend on
numerous variables linked to the composition of the array (type and number of enclosures, splay angles) and the
implementation of the ying or stacking structure (number and location of ying points, site angle). This cannot be
determined without the complex mechanical modeling and calculation offered by Soundvision.
Assessing the safety with Soundvision
The overall safety factor of a specic mechanical conguration always corresponds to the lowest safety factor
among all the linking points. Always model the system conguration with the Soundvision software and check the
