A drive wheel for a power drive unit of a cargo handling system is disclosed. One aspect of the drive wheel is that it includes one or more wear indicators for a tire of the drive wheel. Another aspect of the drive wheel is that it includes one or more features (e.g., at least one protrusion, alone or in combination with one or more slots) that resists relative rotational movement between the tire of the drive wheel and the hub of the drive wheel.

A conveying unit for transporting goods on transport rollers in a transport plane. The transport rollers can be rotated about their respective axes of rotation with an adjustable rotational speed and adjustable direction of rotation. The axes of rotation of the transport rollers are adjustable by rotation about their respective pivot axes by a particular pivot axis angle, and at least two of the transport rollers can be adjusted differently from one another. There is also described a method for adjusting the conveyor unit.
