Design Weight Reduction and Attendant Economics 640355
Weight reduction designed into highway vehicles can be made to pay off in a variety of ways, but the largest by far, is hauling of greater payloads within legal weight limits.
General areas of weight reduction are: use of lesser amounts of similar materials, utilization of lighter materials, use of lighter components for the same purpose, and elimination of unnecessary parts.
Cost increases required to save weight vary over a wide range, and may even be negative in some cases. Value to the operator of the pound saved depends on a multitude of factors, including ability to replace lighter tare weight with payload, degree of utilization, and amount of revenue from hauling the extra pound.
