5. Array configurations ___________________________________________
GRD18 options
The GRD18 is used with 12-24 LR18i arrays and has multiple
mounting options. The picture on the right shows the different pick-
points for flying an array. The A1 & A2 marked points are the default
hoist points.
It is possible to use one pick point from the A1 linear pattern. Use it
only for max. 12x LR18i cabinets
When hanging a 6-12 LR18i array with 2 hoist points, ensure that
the Centre of Gravity is evenly spaced between the two A1 pick
points.
In case of a permanent installation, combine points A1 and 2x A2 for
a stable 3-point hang. Use 1,5T shackles at all times
A3 indicates the mounting position of an angle inclinometer. It has a
4x ø4mm; 16.5mm x 108.8mm hole pattern for the Teqsas laser/
inclinometer.
Hole A4 can be used for a cable sling attachment.
The 2 holes A5 will hold the connection pin between the LR18i angle
arm and GRD18
The picture below shows the orientation of the LR18i angle bar
inside the GRD18 and GRD18B. The angles are also indicated on
the GRD sticker.
