FACTOR OF SAFETY DISCLAIMER

Important: Read Carefully

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 5 to 1 safety limit analysis to ultimate load performed by an independent structural engineering firm. The ratings apply to the Meyer Sound rigging only. You are responsible for 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.

MAPP assumes the top grid is picked up by a front and rear motor along the perimeter of the grid, either directly to the middle pickup points or bridled at 45 degrees or greater to the grid's outermost pickup points. Other rigging configurations may have reduced load capacity. These cases should be reviewed by proper personnel to verify load capacities for alternate configurations.

Bridle angles are measured between the bridle cable and top grid plane.

Center Bar Pickup Points

MAPP Factor of Safety calculations are made for peripheral top grid points -- either corner or middle -- depending on the top grid configuration. Using the center bar pickup points will result in reduced load capacity. These cases should be reviewed by proper personnel to validate the configuration.

Pull-Back Load Status

MAPP Load Status -- when using Pull-Back -- additionally takes into account the Pull-Back Load Status as an additional pass/fail criteria to determine the overall Load Status condition. The Vertical Pull-Back Load Status is the pass/fail criteria. The -10º/+10º status indicators provide the user of the tolerance that exists to each side of the vertical. For all purposes Pull-Back should be as close to vertical as possible as loads will vary. Deviations from a vertical Pull-Back should be reviewed by proper personnel to verify load capacities for alternate configurations.
