LR18i line-array modules and LR18B
line-array bass modules to be flown and ground stacked. The grid can
be suspended from multiple hoist options on top of the grid or with the
central “single pick-point” bar for smaller arrays (all points 14mm/0.55-
in for 1,5T shackles).The GRD18B has a weight of 26 kg / 57 lb and is
certified for a safety-rating of 10:1, for 24 cabinets LR18i, 12 cabinets
LR18B * on the hoist positions on top of the grid.
* (or equivalent weight in mixed configurations)
GRD18EXTBR
This is a “sliding” extension bar, which can be attached on top of the GRD18, to extend the
leverage capabilities of the GRD18, with larger centre-of-gravity (COG) array off-sets.
With the GRD18EXTBR mounted at the front side of the GRD18, the upward array tilt is
extended; With the GRD18EXTBR mounted at the rear side of the GRD18, the downward
array tilt is extended. The front and rear holes measure 14mm/0.55-in to facilitate 1,5T
shackles. Always use both quick release pins for the GRD18/ GRD18EXTBR connection.
