Rigging Safety Analysis has been added to MAPP 3D to provide more detailed information regarding the calculations for LEO, LYON, LEOPARD, and LINA Flown Loudspeaker Systems. With a given array configuration, you can choose an analysis type that indicates whether or not the desired array configuration will be OK to hang. When you insert a Flown Loudspeaker System, the rigging Factor Of Safety feature is enabled and analyzes the configuration as you add or subtract elements and change array angles. If the configuration exceeds the mechanical load limits, a warning is displayed in the edit loudspeaker system properties. Rated load capacities of the Meyer Sound rigging assembly for different splay angle settings are based on testing performed by an independent testing agency, and on safety limit analysis performed by an independent structural engineering firm. The ratings apply to the Meyer Sound rigging only. You are responsible for selecting the safety factor required by local law for your installation, and for determining the adequacy of supporting structure above the hook. PERMANENT INSTALLATIONS MUST BE CERTIFIED BY THE ENGINEER OF RECORD FOR WIND AND SEISMIC LOADING.

LIMITATIONS AND DISCLAIMER: The safety limit analysis provided by this program does not apply, and may not be relied upon, if your loudspeaker system (1) has been improperly installed or maintained, (2) the rigging or loudspeakers of your system have been damaged prior to installation, (3) your indicated configuration of the system has been altered, (4) any weight has been added to your indicated configuration, or (5) your system is in an outdoor venue and remains installed during strong wind conditions. MEYER SOUND ASSUMES NO RESPONSIBILITY FOR ANY PART OF AN INSTALLATION ABOVE THE HOOK OR WHERE ANY OF THE FOREGOING LIMITATIONS APPLY.
