Other KInds of Crawler-Mounted Cranes
In order to be able to power a huge variety of machinery, industrial wheel tractors were adapted during the 1920s, by Fordson and McCormick-Deering. For instance, half-swing shovels and cranes were manufactured by some companies around the power train and engine of the tractor and the wheels became replaced by crawlers.
Crawler tractors came into widespread use during the 1930s. Immediately after, numerous manufacturers started manufacturing attachments for them, like for instance a range of lifting machine devices.
For instance, side-mounted booms were mainly utilized for pipe-laying where it gained its nickname the "pipelayer." These equipments are often utilized these days for attending to cleaning up railroad derailments. Because of their mobility, size and compact design, in addition to exceptional lifting capacity, these kinds of machinery are great for this application. Additionally, swing booms which mounted on top of the engine compartment became available also.
Crawler cranes are like the crawler tractor in that it travels along crawler tracks. These machines can not move fast thanks to their intense weights. Typically, the crane can be controlled by 2 or more cable operated drums and is powered by one engine. The crawler cranes are available with a lattice boom or a telescopic arm which is easy to extend by utilizing hydraulics. The lattice boom needs 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 essential to be built and broken down on location. They have to be transported by truck every time they are relocated. These tower cranes are exceptionally 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 push every new crane part up into place and hence, are self-erecting.
