A Potted History of CAT Equipment
CAT equipment owes its origins to the machine innovations that sprang from the Industrial Revolution in the early 20th century. Back then, construction was largely reliant on manual labor, with workers leaning on shovels, wheelbarrows and horsepower to shift materials. But a technological transformation was just around the corner.
The first major development arrived in the shape of steam-powered traction engines. Although loud, dirty and unreliable by today’s standards, these machines could haul heavy loads well beyond the capacity of horses, signalling the start of mechanized construction. However, traction engines still faced limitations in terms of the terrain they could handle.
The breakthrough that truly initiated the era of earthmoving equipment came in 1925 when a tiny Californian firm called the Caterpillar Tractor Company launched a peculiar crawler-type tractor dubbed the Caterpillar 60. Its tracks allowed it to traverse muddy ground and slopes effectively, and its success sparked the establishment of the Caterpillar Inc corporation.
Over the ensuing century, Caterpillar Inc was at the forefront of bringing mechanized power to construction sites around the globe. Through countless innovations, it rolled out improved models of bulldozers, excavators, cranes and loaders that transformed efficiency and productivity. Other notable developments include the introduction of diesel engines and hydraulics in the 1950s and integrated computerized systems and GPS technologies from the 1980s onwards.
Nowadays, over 35 different types of CAT equipment are deployed globally, from rugged 35-ton excavators equipped with the latest precision control tech, to nimble skid-steer loaders that can squeeze into the tightest of spots. This equipment is built robust and ready to take on the most challenging of construction jobs.
So that’s a quick gallop through the history of CAT – now let’s get better acquainted with the stars of the show…the machines themselves!
