The History of Cat and the Evolution of the 336 Excavator
A Legacy of Innovation: The Birth of Caterpillar Inc.
The roots of Caterpillar Inc. trace back to the early 1900s, when two visionary inventors, Benjamin Holt and Daniel Best, revolutionized the agriculture and construction industries with groundbreaking equipment. In 1904, Holt developed the first commercially successful track-type tractor, nicknamed the "Caterpillar" for the way it moved over soft soil. This innovation laid the foundation for a company that would become a global leader in heavy machinery.
In 1925, the Caterpillar Tractor Company was officially formed through the merger of Holt Manufacturing Company and C.L. Best Tractor Co. Over the decades, Caterpillar expanded its product line from agricultural tractors to include construction, mining, and industrial equipment. Today, the company is known simply as Cat and is synonymous with durability, reliability, and cutting-edge technology.
The Rise of the Cat Excavator Line
Excavators became a critical addition to Cat’s product portfolio in the mid-20th century, allowing the company to cater to the growing demands of the construction and mining industries.
