Volta accepted a challenge of developing a narrow composite belt that carries car chassis through an assembly line, past consecutive workstations. Belts were designed for a system 25 metres between axles and 55mm wide. These belts transport loads in excess of 4 tons (10500 lbs). Wider belts enable even heavier loads to be carried.
The belts do not elongate and have no joint. They are wear and paint-resistant, making them the perfect choice for an industrial setting where break downs would require a prolonged and expensive shutdown. With the old-style belt, partly assembled cars would be required to be removed during the changeover. The cars would have to be replaced on the line costing extending down time before they could continue production.
