A powered roller conveyor especially effective for upgrade conveyance of light loads of 15kg to 60kg, 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 said resin coating is an undulating surface having ridges 1a which extend axially and parallel and which, seen in a cross-section of said roller, are arranged with a uniform spacing pitch of about 3mm and have a height of about 2mm. For manufacturing these rollers, no new additional equipment nor much labor is required, 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.
Convoyeur à rouleaux motorisés particulièrement efficace pour le transport ascendant de charges légères de 15 à 60 kg, dans lequel le revêtement de résine des rouleaux (1) est un caoutchouc mou à base de polyuréthane ayant un degré de dureté de 65 à 80 et dont la surface extérieure est une surface ondulée ayant des crêtes (1a) qui s'étendent parallèlemen les unes aux autres dans le sens axial et qui, vues en coupe du rouleau, sont régulièrement espacées d'environ 3 mm et ont un hauteur d'environ 2 mm. La fabrication de ces rouleaux ne nécessite pas d'équipement additionnel, ni beaucoup de travail, ce qui permet de fournir des rouleaux à bas prix et, de ce fait, contribue à la réduction du coût du convoyeur à rouleaux. Ce convoyeur est idéal pour le transport ascendant sur des pentes fortement inclinées.
