Different Types of Crawler-Mounted Cranes

Industrial wheel tractors in the 1920s, including those built by McCormick-Deering and Fordson were quickly modified in order to be able to power a large variety of machines. Like for example, half-swing shovels and cranes were made by some companies around the power train and engine of the tractor and the wheels became replaced by crawlers.



During the 1930s, crawler tractors came into widespread use. Immediately after, many manufacturers began manufacturing attachments for them, such as a variety of lifting machine devices.



For instance, side-mounted booms were mainly utilized for pipe-laying where it gained its nickname the "pipelayer." These kinds of machinery are currently usually utilized for attending to cleaning up railroad derailments. Because of their mobility, size and compact design, along with excellent lifting capacity, these machinery are great for this application. Furthermore, swing booms which mounted on top of the engine compartment also became available.



Crawler cranes are like the crawler tractor in that it travels along crawler tracks. These equipments can not move fast due to their intense weights. Usually, the crane is powered by one engine and may be controlled by 2 or more cable operated drums. The crawler cranes are available with a lattice boom or a telescopic arm that can be extended easily utilizing hydraulics. The lattice boom has to be assembled by hand by adding many sections.



Tower Cranes

Usually found in big construction projects, tower cranes are required to be erected and broken down on location. They need to be transported by truck each time they are relocated. These tower cranes are very tall. They allow construction crews to move concrete building components or heavy steel to the tops of tall buildings. Tower cranes utilize a hydraulic system to be able to push every new crane part up into position and hence, are self-erecting.
