MATERIALS HANDLING
than comparable to three or four layer conventional belting. For example, an Ultra X3 single-ply belt can pull up to 56 tonnes. A significant additional benefit of this method is that finger splice joints are stronger and more durable so the need to repair and re- splice joints is much less frequent. Another advantage is that X Series
single and dual-ply belts are more flexible, so they are also better suited for use on mobile conveyors, which are notorious for having small diameter pulleys where the continual flexing places greater dynamic stress on the inner carcass and splice joint, therefore seriously limiting what can normally be fitted.
BETTER FOR THE ENVIRONMENT The reduction in environmental impact is also considerable. Having only one or two layers rather than three, four or more layers helps to reduce energy consumption (they are typically 10% lighter) and maximise production efficiency. It also means that less rubber is used, including a corresponding reduction in the chemicals and additives used to make it, together with a dramatic reduction in non-bio-degradable synthetic fabric.
Most conveyor belts do not provide a cost-efficient working lifetime
DEFYING CONVENTION For some, the very idea that a single or dual-ply construction belt can provide the necessary tensile strength while possessing considerably more resistance to damage is difficult to comprehend. The answer lies in a combination of the amazing innate strength of the fabrics together with a higher level of splice efficiency. Although a step splice can be used to join a dual-ply UsFlex, single-ply constructions require a finger-splice joint (depending on the application, mechanical fasteners can also be used on X Series single-ply belts). The enormous advantage of finger splice joints is that they retain up to 90% of the belt’s tensile strength. By comparison, a 2-ply step splice only retains a maximum of 50% and a 3-ply step joint only achieves a maximum tensile strength of 67%. Single and dual-ply belts joined by a step splice create equivalent tensile strengths and belt safety factors that are more
