Other KInds of Crawler-Mounted Cranes

Industrial wheel tractors during the 1920s, including those made by McCormick-Deering and Fordson were rapidly adapted in order to be able to power a huge range of equipment. For instance, half-swing cranes and shovels were made by several companies around the power train and engine of the tractor and the wheels became replaced by crawlers.



Crawler tractors came into widespread use in the 1930s. Immediately after, many manufacturers began manufacturing attachments for them, including various lifting machine devices.



Side-mounted booms for instance, were used primarily for pipe-laying at first and the machine got the nickname "pipelayer." These equipments are often used now for attending to cleaning up railroad derailments. Because of their compact design, mobility and size, in addition to exceptional lifting capacity, these types of machinery are ideal for this use. As well, swing booms which 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 machinery could not move fast due to their intense weights. Usually, the crane may be controlled by 2 or more cable operated drums and is powered by one engine. The crawler cranes are available with a telescopic arm or a lattice boom which is easy to extend by utilizing hydraulics. The lattice boom must be assembled manually by adding many sections.



Tower Cranes

Tower cranes are the ones found in large construction projects. These types of cranes are necessary to be built and broken down on location. They have to be transported by truck each 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 position and therefore, are self-erecting.
