There are many different types of cranes that are available through crane hire, so it is important to know what each crane is designed for. It is important to note that cranes have been used for more than 2000 years now to lift weights despite the fact that they look modern. In the olden days, cranes were used to build medieval churches as well as monuments especially in Rome. Cranes have both simple and complicated means of use and we are going to look at them.
The first kind of crane is the mobile crane that has a telescopic booth mounted on a movable platform. It is the levers and the pulleys that move the boom of this crane while at the end of it it has a hook attached at its bottom. 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. The platform of a mobile crane may either have wheels that are designed for railroad tracks or caterpillar tracks.
Depending on the job the crane is to do, the hook at the end of it can be replaced with a wrecking bucket. A crane may either be used for moving earth or even for demolition as the hook at its end can be replaced with a wrecking bucket. Truck mounted cranes and rough terrain cranes are also essentially mobile too. The truck-mounted crane will have outriggers to keep the crane fully stable when in use. Trucks designed to work in rough terrains are as good as a four wheel drive and are very good for offering transport.
The other type of cranes is the loader cranes that are used to load goods on trailers and are powered by hydraulic booms. the loader cranes are similar to hydraulic cranes as they are all fitted with telescopic booms for easier use.
You may find that you require floating cranes for crane hire if your project is involved within the shipping industry. When building ports and salvaging ships, floating cranes are the best as they can operate in water. They can also unload ships and are designed specifically for handling very heavy loads or awkward shaped containers.
The other type of cranes is the tower cranes, they however, 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. These cranes are often used for sky scraper construction and the build of tall buildings. The design of cranes is based on two major considerations.First is to lift specified mass, the second is its stability, and it should not topple over while performing lifting operations.
