A cargo power drive unit (PDU) includes a housing, and a shaft rotatably
mounted in the housing. The shaft has a longitudinal axis, an end, and a
spindle outwardly extending from the end. The spindle is radially offset
from the longitudinal axis. The PDU further includes a lift roller having
a center axis, and having an opening that is radially offset from the
center axis. The spindle is non-rotatably received in the opening of the
lift roller. When the shaft rotates in the housing and the lift roller
contacts a stationary support beneath the housing, at least a portion of
the housing is lifted away from the stationary support by the roller.
