Abstract

A roller made lighter through the use of lightening elements. The inventive roller, with its lightening element(s), is lighter yet maintains its overall dimensions, is strong and durable enough to withstand the rigors of the transportation industry and/or is cost effective to produce and maintain. The lightweight roller may be part of a system having at least one operable roller unit, each roller unit having a roller, cylindrical in shape having a length and a diameter, and a center aperture extending through the length of the roller, an axel/shaft having a diameter sized to rotatably fit within the central aperture of the roller, the shaft further having a retention mechanism located upon the shaft ends and an elongate “U” shaped roller rack, the roller rack sized to extend the length of the roller and having a pair of upwardly extending arms located adjacent the ends of the roller, each arm end having an aperture sized to receive the respective shaft end and locate the shaft with the roller in a fixed location. The roller system has at least one roller, preferably more or all of the rollers, having internal and/or external lightening elements.
