Development History of crawler cranes

Crawler cranes have a very large lifting capacity, which is very commensurate with their large shape, the crawler unit, the chassis of the crawler crane, has improved its ground grip reliability and operation stability. Before the crawler is applied to a crane, the world has successively experienced rotary arm cranes, bridge cranes, metal cranes, steam-powered cranes, electric cranes, and fuel-driven cranes, the crane family is already huge.

 

The crawler was not directly applied to cranes at the beginning of its birth. The world's first practical crawler was born in the United States in 1901, at that time, it was intended to give forestry traction vehicles good walking performance on soft land. Three years later, an American mounted a crawler on a steam tractor. The American name is Hort. His tractor factory is now the predecessor of Caterpillar, an American Engineering Machinery Group Company.

 

After using the crawler on a tractor, he continued to try new ideas. Later, he successfully developed the crawler bulldozer. In 1915, an armored vehicle (the first "tank") emerged in the UK. Since then, crawler devices have been widely used in construction machinery. The first successful combination of crawler devices and cranes was on a truss Crane. By now, crawler cranes have become an important branch of the Crane family.
