Caterpillar (often simply referred to as CAT) are the single largest manufacturer of construction, mining and forestry machines in the world.
Caterpillar Inc. was established in the late 1890s when Daniel Best and Benjamin Holt were experimenting with the use of steam tractors in industrial farming.
Caterpillar's line of vehicles range from tractors to hydraulic excavators, backhoe loaders, motor graders, off-highway trucks, wheel loaders, and agricultural tractors. They are used in road-building, mining, construction, forestry, transportation, energy and material-handling industries.
