Euclid Trucks

The Euclid Company of Ohio was a company specialized in heavy equipment for earthmoving, namely dump trucks and wheel tractor-scrapers, that operated from the United States of America from the 1920s to the 1950s, then it was purchased and converted into a section of General Motors and later on by Hitachi Construction Machinery.

The Euclid Company of Ohio specialised in off-road heavy haulers, specifically designed as off-road haulers - as compared to other companies, that modified on-road trucks for off-road earth-hauling.

The Euclid Crane and Hoist Co, owned by George A. Armington and his 5 sons, was a large, respected and profitable operation, when they introduced the Euclid Automatic Rotary Scraper in 1924 - soon followed by the Euclid Wheeler (wheeled) scraper. These earthmoving products were conceived by George's eldest son, Arthur, who envisioned a good future in designing earthmoving equipment, and steered the company into the earthmoving field. The two models of scrapers were successful, and a third model, the Euclid Contractors Special, designed to cope with hard ground, was even more successful.

Arthur and his father had built a successful prototype crawler, and tested it on the family farm, but the idea was dropped for reasons unknown. The success of the scrapers led to the formation of the Road Machinery Division, of Euclid Crane and Hoist, in 1926. Big public works construction programs of 1927 and 1928, requiring large excavations, saw further success of the Euclid Road Machinery division.

Euclid produced crawler wagons on tracks (similar to Athey Wagons) known as Euclid Tu-Way haulers. The crawler track speed restriction was seen as a problem, and the next version used steel wheels for improved speed. George Armington Jr was a keen hydraulics designer, and produced the first hydraulic Euclid dumpers around 1930.

The Great Depression did not appear to affect Euclid greatly, and the expansion of the earthmoving portion of the Euclid business, led to the incorporation of the Euclid Road Machinery Co, on July 11, 1931. This company remained a subsidiary of Euclid Armington Corp, until January 1, 1933, when the companies were separated - and Euclid Road Machinery, became a producer of fast, off-road earthmoving haulers.
