NOTE: This condition is limited to operation with the main
boom on fully extended outriggers only.
c) If V(z) is > 20.1 m/s (45 mph), then lifting is NOT
permitted. Cease lifting operations and lower and retract
the boom.
In both cases a) and b) above, the lift may also be limited by
the projected wind area of the load Ap and by the wind drag
coefficient Cd: This limit can be determined by comparing
the Actual wind resistance area with the Allowable wind
resistance area.
Refer to Figure 2-2 for a simplified calculation method to
determine permissible wind speed.
