Alternative Lifting Method

If it is only possible to use a single hoisting device to lift an
AFDH drive unit to position it for installation, a spreader
bar should be used to allow adjusting the rigging as
necessary to balance the unit around its center-of-gravity
to ensure full control of the unit during lifting.
