Letourneau Heavy Equipment: The Mechanical Drive Era (1921-1953) (A Photo Gallery) USED","description":"In the history of heavy equipment development, no single man’s name is \nmore respected or revered as that of R. G. LeTourneau. Robert Gilmour \nLeTourneau is considered by many to be the dean of high-speed mobile \nearthmoving equipment. His designs of the 1920s, 30s, and 40s laid the \nfundamental groundwork for many of the earthmoving machines we see on a \ndaily basis. Self-propelled, rubber tired scrapers, bulldozing blades, \nand rippers were all conceived under his engineering genius in the quest \nfor moving material at the lowest-cost-per-yard. The time period of 1921 \nto 1953 saw many of R. G. LeTourneau’s most important heavy-equipment \nintroductions, such as the Carryall and the Tournapull, and the initial \ndevelopment of the electric drive wheel. This first volume of fantastic \nmachine creations covers the early years up until the sale of the \ncompany to Westinghouse in 1953. Standard production, specials, and \nexperimental machines in rare archival images, some in print for the \nvery first time, help showcase what made R. G. LeTourneau so important \nin the heavy equipment industry.","brand":"Ertel Publishing","offers":[{"title":"Default Title","offer_id":44139720376600,"sku":"B05324#LN","price":32.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0057\/9813\/3831\/files\/9781583882146-500x500.jpg?v=1772276237","url":"https:\/\/www.midlifeclassiccars.com\/cs\/products\/r-g-letourneau-heavy-equipment-the-mechanical-drive-era-1921-1953-a-photo-gallery-1","provider":"MidlifeClassicCars.com","version":"1.0","type":"link"}
