Abstract
A freight loading system is provided comprising at least one drive roller unit for conveying objects, in particular containers, pallets or the like, on the freight deck of an aircraft.

At least one sensing means comprising a measurement roller is provided and which likewise can be brought into connection with the undersurface of the object. At least one measurement sensor is also provided and is so constructed and so connected to the measurement roller or accommodated in the measurement roller that the circumferential velocity of the roller and/or a load acting upon it substantially perpendicular to the freight deck and/or a horizontal force acting on it during braking of the measurement roller, or a corresponding torque, are converted to measurement signals. These signals are sent to a control device which is in controlling or regulating connection with one or more drive motors of drive roller units installed in the freight deck…
