With smooth surface conveyor belts the maximum conveying angle of inclination is approximately 20° depending on the material. Using chevron cleated belts makes steeper angles of inclinations up to 40° possible, which allows for higher lift in lesser space.Chevron conveyor belts have rubber cleats that are integrally vulcanized with the top cover of the belt. These profiles are made with highly abrasion resistant rubber types and are offered in softer compounds (45 to 50 Shore hardnes are shaped in such a manner that there is no need for special idlers and these can be run on conventional conveyors. The pitch between two cleats ensures a smooth ride over return idlers.
