J.C. Bamford Excavators Limited, universally known as JCB, is a British multinational corporation, with headquarters in Rocester, Staffordshire, manufacturing equipment for construction, agriculture, waste handling and demolition. It produces over 300 types of machines, including diggers (backhoes), excavators, tractors and diesel engines. It has 22 factories across Asia, Europe, North America and South America; its products are sold in over 150 countries.
Many of the vehicles produced by JCB are variants of the backhoe loader, including tracked or wheeled variants, mini and large versions and other variations for carrying and moving items, for example forklift vehicles and telescopic handlers for moving materials to the upper floors of a building site. Wheeled loading shovels and articulated dump trucks are also produced.
...the Lego Technic range featured a scale-model of the JCB backhoe: Lego set 8862, complete with working hydraulics systems (simulated using pneumatics) and many other features of the original.
