Company

Company

William Adams has over 90 years of association with Caterpillar. It’s an alliance that dates back to 1926 – just a year after the first Caterpillar branded two-ton tractor, the Caterpillar Sixty rolled off the assembly line. Eight decades of partnership has cemented robust links between the two companies. Today, we lead the way with great products, unrivalled product support and, of course the best asset in business, our people.
