A roller for a conveyor system comprises a nonlinear bore hole to facilitate retention of the roller on a roller-receiving portion of a corresponding shaft. A nonlinear bore hole comprises a central cylindrical portion for receiving a roller-receiving portion of the shaft and unaligned slots in communication with the central cylindrical portion to prevent migration of the roller from the roller-receiving portion.

An aircraft loader 54 includes an upper loading platform 50 and an underlying frame 52 with the frame utilizing the bogey suspension system 60, as well as carrying auxiliary lift system 400 at the rearward end thereof for assisting in the initial lifting of the platform relative to the frame. Powered roller assemblies 100, 110, 120, and 130, composed of hollow drive shafts, may be conveniently assembled and disassembled from the underside of loading platform 50. A plurality of upwardly convex-shaped static slider elements 200 facilitate unidirectional movement of loads on the platform 50. At the forward end of the platform, a guard or side rail 316 is rotatable from a retracted position within the confines of a control platform 68 to a forwardly directed position toward the fuselage of the aircraft. The side rail 316 is shaped to resemble the exterior cross-sectional shape of the fuselage, thereby to close the gap between the forward end of the loading platform and the fuselage, for the protection of loader personnel.
