Robert Gilmour LeTourneau is considered by many to be the dean of high-speed mobile earthmoving equipment. His designs of the 1920s, 30s, and 40s revolutionized the earthmoving industry. During the 1950s and 1960s, LeTourneau was able to develop and employ one of his greatest engineering design achievements - the electric drive wheel concept. This second volume of fantastic machine creations covers the time period from 1953 up until the sale of the company to Marathon in 1971. Standard production, specials, and experimental machines are shown in rare archival images, some being shown in print for the very first time, help showcase what made R. G. LeTourneau so revered in the heavy equipment industry.
Power Shovels is a celebration of the land leviathans that have inhabited the open pit mines over the past century. Due to their massive size and unbelievable capabilities, interest in these machines extends far beyond their role in the extraction of minerals and precious metals.
