Warning
For outdoor uses, we recommend using at least a BGV D8+ hoisting device to avoid wind
causing the release of the secondary safety device.
If wind speeds higher than Beaufort 5 are expected, you must constantly consider the wind
speed and its possible influence on the array as well as the fact that the wind speed increases
the higher the array is.
With expected wind speeds exceeding Beaufort 5, construct the rigging and safety points so
that they can carry at least twice the static load.
With wind speeds exceeding Beaufort 6 (14 m/sec.), arrays are not recommended.
As of a wind speed of Beaufort 6, you must clear the area under the speakers. Effectively
prevent the arrays from swaying in the wind by tying them off or using a lateral fixation.
If the suspended load sways, it can create significant inertial force that can result in the PA
tower structurally collapsing or tipping.
With wind speeds of Beaufort 8 or more, you must lower and disassemble the array.
