In some industries, the most common reason for having to repair or replace a belt is due to rip or impact damage rather than day to day wear. In more extreme conditions where heavy, sharp lump sizes and/or large drop heights are involved, it is essential to have a carcass that is designed to dissipate impact and provide strong resistance against trapped objects that rip through the belt. It is also important to have rubber covers that protect the carcass as much as possible against impact and rip propagation.
