WARNING - WIND SPEEDS
The erection and dismantling of a motorized unit setup (including the base, the
bridges, the masts, the mast ties and all the other components) must not be conducted
when wind speeds exceed 28 mph (45 km/h). Freestanding installations and setups
equipped with weather protection, when allowed, must not be used with wind
speeds exceeding 28 mph (45 km/h). Weather protection, when allowed, must not
be used when work is performed on an open air structure. A motorized unit setup
with mast ties must not be operated when wind speeds exceed 35 mph (56 km/h).
If wind speeds are expected to exceed 102 mph (164 km/h), the motorized unit must
be brought down to base level.
When a freestanding installation is not in use:
• The motorized unit must be brought down to base level
When a tied installation is not in use:
• It is mandatory to leave the platform between two tie levels
• All loads must be removed from the setup, except all counterweights applied on
the setup
