Cranes come in different types and sizes and it is important to know every kind. Most of us think that cranes are some modern discovery but they are not, they have been in use for more than 2000 years now. In the olden days, cranes were used to build medieval churches as well as monuments especially in Rome. Here in this article we shall look at the simple and complex uses for cranes.
The first kind of crane is the mobile crane that has a telescopic booth mounted on a movable platform. Pulleys or levers will raise the boom of this crane, usually a hook will be found at the end of this crane. Mobile cranes are suitable for city work as they can be transported easily; crane hire companies often aid the transport and lifting of their crane. Moreover, the platform of a mobile crane may either be fitted with caterpillar trucks or even wheels for a rail road.
The mobile crane can be used for demolition or earthmoving as the hook at the end of the crane can be changed to a ball or wrecking bucket, dependent on the crane hire job. Other cranes that are mobile are rough terrain cranes and truck mounted cranes. To keep a truck mounted crane stable it is good for them to be fitted with outriggers. Moreover, those terrains that are designed for rough terrains are just like a four wheel drive.
The other type of cranes is the loader cranes that are used to load goods on trailers and are powered by hydraulic booms. Of importance to note is that telescopic cranes are similar to loader cranes as they are all fitted with telescopic booms for easier use.
However, those in the shipping industry would need to buy the floating cranes for flexibility while loading cranes. When building ports and salvaging ships, floating cranes are the best as they can operate in water. The floating cranes can be used to offload awkward looking containers as they are just designed to do this.
other kind of cranes used for hire are the tower cranes , despite the fact that they do not have a movable base. They are very taller and the construction of the crane has to occur section by section. the boom of this crane is perpendicular to the base of the crane in order to make it more stable. Tower cranes are designed in that they can aid the construction of very tall buildings as well as the sky scrapper buildings. When deciding on the design of the crane it is generally based on two major things.First is to lift specified mass, the second is its stability, and it should not topple over while performing lifting operations.
