MG-MINA/LINA/750-LFC GRID LOAD RATINGS
The following table lists the maximum suspended weight for the MG-MINA/LINA/750-LFC grid.
Requirements for MG-MINA/LINA/750-LFC Grid Load Ratings
The load ratings in Table 4 are only supported when the following requirements are observed:
• Any combination of grid pickup points can be used. However, if a bridle is used between pickup points, the bridle angle
at the apex must not be greater than 90 degrees.
• Using a bridle leg length that results in an apex angle wider than recommended reduces the load rating and may damage
the MG-MINA/LINA/750-LFC grid.
• The array should not be lifted from points other than those on the grid.
• The grid tilt should not be greater than the one achieved by the natural rotation of the array.
• The grid tilt should not be greater than the angles in Table 4 with respect to the horizontal. Negative angles are downtilt
and positive angles are uptilt.
• The maximum number of LINA loudspeakers that can be flown is based on a weight of 43 lbs (19.5 kg) for each LINA
cabinet.
• The maximum load ratings regard the MG-MINA/LINA/750-LFC grid and flown loudspeakers as a system, including the
links and pins. Thus, the maximum stress point could change from one element to another in the system.
• The weight of any additional items suspended with the array, such as downfill loudspeakers, transition accessories, and
cable, must be considered when calculating the maximum load.
• The weight of the MG-MINA/LINA/750-LFC grid has not been included in Table 4. The table rates the maximum load for
the grid. Pickup points and motors that will suspend the grid must be rated to the support the total weight of the grid
(34.7 lbs, 15.74 kg) and its suspended loudspeakers (see Table 4).
• Always use properly rated rigging hardware. 5/8-inch shackles are recommended for the MG-MINA/LINA/750-LFC
pickup points.
