Progress in Hough Payloader Productivity with the H-400 670286

This paper covers the development of a front end shovel loader capable of meeting market requirements for increased productivity at lower cost per ton or cubic yard. Use of bigger hauling units required much larger mobile loading equipment, and on-the-job experience and research promptly determined the size and features required for its profitable manufacture. Following design and building of prototypes, proving ground, field, and laboratory testing eliminated deficiencies and the result, the Hough Model H-400, became available in 1965 as the world’s largest production-built articulated loader.
