Different Types of Crawler-Mounted Cranes

In order to be able to power a huge range of machinery, industrial wheel tractors were adapted in the 1920s, by McCormick-Deering and Fordson. Like for instance, half-swing cranes and shovels were manufactured by several companies around the engine and power train of the tractor and the wheels became replaced by crawlers.



Crawler tractors came into widespread use during the 1930s. Immediately after, numerous manufacturers started making attachments for them, like for example a variety of lifting equipment devices.



Side-mounted booms for example, were utilized mainly for pipe-laying at first and the machinery got the nickname "pipelayer." These machines are presently normally utilized for attending to cleaning up railroad derailments. Because of their mobility, size and compact design, in addition to exceptional lifting capacity, these types of machines are ideal for this use. As well, swing booms that mounted on top of the engine compartment also became available.



Crawler cranes are similar to the crawler tractor in that it travels along crawler tracks. These equipments could not move fast thanks to their intense weights. Normally, the crane is powered by one engine and can be controlled by 2 or more cable operated drums. The crawler cranes come equipped with a lattice boom or a telescopic arm which could be extended easily utilizing hydraulics. The lattice boom has to be manually assembled by adding multiple sections.



Tower Cranes

Tower cranes are the ones found in big construction projects. These kinds of cranes are necessary to be built and broken down on location. They must be transported by truck each time they are relocated. These tower cranes are very tall. They enable construction crews to move heavy steel or concrete building parts to the tops of tall buildings. Tower cranes utilize a hydraulic system to push each new crane section up into place and thus, are self-erecting.
