Each conveyor belt includes an upper section configured to receive an object to be moved and each conveyor belt can move between a first raised position in which the upper section of the belt is located above the rolling surface defined by the rollers of the freight loading system and a second position in which the upper section of the belt is located below the rolling surface.
