Inventor of the World’s First Crane and Excavator Heavy Equipment The history of the crawler crane began when it was born around the 1920s in America. At that time the company Northwest Engineering made the first crawler crane. However, at that time the form was still very simple.
The crane is just like a pulley attached to a rail. Furthermore, a more modern crawler crane was made by Chicagoans, Americans, namely Ray and Charles Moore . The machine was steam powered and weighed 15 tons. This version began to be developed and marketed widely in 1925.
From this discovery, many construction equipment companies began to develop more sophisticated crawler cranes. One of the famous ones is the crawler crane with the first hydraulic mast made by Hymac, a company from England in 1966. The crane is capable of lifting thousands of tons of material. This crane machine, which is famous for its ‘ caterpillar ‘ wheels, usually has a total height ranging from 50 meters to more than 120 meters with weighing tens to hundreds of tons.
One of the advantages of a crawler crane is its plus mobility in the construction area. This machine can run even when carrying a heavy load. Use in locations with unstable soil also carries a lower risk. Using wheels similar to those of a tank, crawler cranes do not easily get stuck in sand or muddy ground.
CRANE (crane) is a type of material handling, which uses a hoist (chain hoist or wire rope hoist) & a prefabricated steel structure, where the main use of this system is to raise and lower loads vertically and horizontally. Because of these benefits, cranes have become an important part of factory, warehouse and workshop operations. In addition, this system can also be installed indoors and outdoors.
