|Known as 'The Dean of Earthmoving', R.G. LeTourneau is considered one of the world's greatest inventors of earthmoving and material handling equipment. With outstanding photography, this overview of 90-years-plus of manufacturing features LeTourneau’s earliest earthmoving equipment introductions in 1921, all the way up to today's giant loaders produced in Longview by Joy Global as ''P&H Generation 2'' wheel loaders. Even though Joy Global has officially announced that it is removing the ''LeTourneau'' name from the mining product lines, as a tribute to its heritage, a small ''LeTourneau'' plate is now fitted inside the cab. This companion book to the three previous publications — R.G. LeTourneau Heavy Equipment: The Mechanical Drive Era 1921- 1953, R.G. LeTourneau Heavy Equipment Photo Gallery: The Electric-Drive Era (1953-1970), and Modern LeTourneau Earthmoving Equipment since 1968 — includes much updated information and all new images of the LeTourneau enterprise. 176 pages, over 300 ill. s/b.
