The suspension system is designed to
accommodate loads through an angle of up to
55° from vertical —both forward and aft.
However, when loads exceed 55°, the travel
stops on the Pillow Blocks prevent the
Suspension Beam from further rotation and
cause bending stresses to be carried by the
Load Cell. Care should be taken to avoid this
flight regime.
The situation is most likely to occur when
flying at high speeds with light loads, which
have large aerodynamic drag, for example - an
empty fire or fertilizer bucket or an empty long
line. Figure 6 illustrates the adverse loading
situation.
