Caterpillar — manufacturer of hydraulic systems
Caterpillar is one of the world’s leading companies in the heavy equipment industry. The brand is globally recognized for its powerful engines, construction machinery, generators, and integrated solutions for energy and transportation sectors.
Caterpillar hydraulic pumps and motors are primarily integrated into original CAT equipment, ensuring stable operating pressure, efficient power transmission, and precise control of working processes under heavy-duty conditions.
History and development of Caterpillar
The history of Caterpillar began with innovative engineers from California — Daniel Best and Benjamin Holt. In 1904, they developed the first steam-powered agricultural tractor with a track-type undercarriage. This invention became the prototype of modern construction machinery. The name Caterpillar refers to the track system that revolutionized equipment mobility on soft ground and rough terrain.
The official founding year of the company is considered 1925, following the merger with Best Tractor Company, which formed Caterpillar Tractor Co. In the 1930s, the company began producing diesel engines, which became a cornerstone of its global growth.
During World War II, Caterpillar equipment was widely used in large-scale infrastructure projects worldwide. In the 1980s, the company expanded its global manufacturing network and introduced advanced technologies in heavy machinery and generator production. Today, Caterpillar is a global corporation manufacturing wheeled and tracked equipment, power systems, and environmentally focused solutions aimed at reducing emissions.
