LOAD RATINGS OVERVIEW

All of the load ratings in this assembly guide take the following into consideration:

Prerequisite Conditions

The following conditions must be met to achieve the load ratings shown in Tables 1, 2 and 3:

■ Any combination of pick-up points can be used. If a bridle is used between pick-up points on the MG-MICA, the

angle of the bridle at the apex is no greater than 90 degrees.

■ The optional MGCP-MICA center point rigging beam is not used.

■ The tilt of the grid must be no larger than the one achieved by the natural rotation of the array or the limit described

in each table.

■ The array is not pulled from points other than the ones on the MG-MICA grid and no pull-back motor should be

used for tilting the array.

■ The weight of the MG-MICA grid itself has not been included (unless it is noted). These tables rate the grid. For

pick-up points and/or motors where the grid will be supported, the weight of the grid needs to be added – 113.5

lbs (51.4 kg).

■ The maximum number of MICA loudspeakers that may be hung in each conﬁguration is based on the MICA weight

of 155 lbs (70.3 kg) to give some margin and/or allow the use of the optional rain hood with respect of the 150 lbs

published speciﬁcation.

■ The load ratings and maximum weights allowed regard the MG-MICA grid and ﬂown loudspeakers as a system,

including links and pins. Thus, the maximum stress point could change from one element to another in the system.

CAUTION: Using a bridle leg shorter than the recommended length for each conﬁguration will reduce

the load rating and may damage the MG-MICA grid.

CAUTION: Always use properly rated rigging hardware. The use of 3/4" shackles for the MG-MICA

grid’s pick-up points is recommended.

With the use of transition accessories, you can also integrate other M Series loudspeakers, to form combined arrays.

CAUTION: The weight of any additional items hung with the array, such as downﬁll loudspeakers and

transition accessories and cable, must be considered when calculating maximum load.

The load rating of the MG-MICA depends on two main factors:

■ Where on the grid the center of gravity (COG) of the array underneath falls.

■ The grid tilt angle.

The maximum grid tilt angle depends on whether the array is connected to the grid in the front ﬂown or rear ﬂown

conﬁguration.
