Crawler crane The crawler crane is a self-propelled crane with a lattice or telescopic boom, the frame of which is supported by a chain train.
Crawler cranes are used to carry heavy loads on construction sites: they can lift several hundred tons and must be stabilized by very heavy counterweights. Due to their large mass, crawler cranes are transported from one work site to another on heavy equipment carriers.
The telescopic boom can deploy hydraulically quickly, while the assembly of the lattice boom takes longer. However, some lattice boom crawler cranes benefit from a quick assembly system which saves time when commissioning the crane. The crane can also be fitted with a quick coupler which facilitates installation.
Historically, the first crawler cranes were marketed in the USA in the 1930s by Manitowoc and Ruston-Bucyrus, before being developed by Ransomes & Rapier and Caterpillar. Nowadays, the crawler crane market is experiencing a revival with the launch of new crawler crane models specially designed for the maintenance of wind farms.
