Machine performance must be ultimately be measured in unit cost of material moved, a measure that includes production and costs. Factors bearing directly on productivity include such things as weight to horsepower ratio, capacity, type of transmission, speeds and operating cost. The Performance Handbook considers these things in detail. This Handbook is intended as an aid which, when coupled with experience and a good knowledge of local conditions, can assist in estimating true machine performance. Many sections of the Handbook include tables or curves showing cycle times or hourly prodution of Caterpillar machines under certain conditions.
