ABSTRACT:
A powered roller conveyor especially effective for upgrade conveyance of light loads of 15 kg to 60 kg, wherein the resin coating of rollers 1 is a soft polyurethane rubber having a hardness of 65 to 80 degrees and the outer surface of the resin coating is an undulating surface having ridges 1a which extend axially and parallel and which, seen in a cross-section of the roller, are arranged with a uniform spacing pitch of about 3 mm and have a height of about 2 mm. Manufacturing these rollers requires no new additional equipment nor much labor, which makes it possible to provide low-priced rollers and hence contribute to cost reductions for the roller conveyor. This conveyor is ideal for upgrade conveyance along slopes of large angles.
