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. Romans were the first people to use cranes while building monuments as well as churches. Here in this article we shall look at the simple and complex uses for cranes.
One simple crane is the mobile crane; this crane has a telescopic boom that is 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. When it comes to the wheels of a mobile crane, they may be designed for caterpillar or rail trucks.
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. The rough terrain cranes and mounted cranes are also mobile. The truck-mounted crane will have outriggers to keep the crane fully stable when in use. Cranes that are designed for rough terrain have a base that is not dissimilar to a 4 wheel drive vehicle; they are good for picking up transport materials.
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.
You may find that you require floating cranes for crane hire if your project is involved within the shipping industry. They are situated in water and are usually used for the construction of ports, to salvage ships or to aid with building bridges. They can also unload ships and are designed specifically for handling very heavy loads or awkward shaped containers.
Tower cranes are commonly used for crane hire, yet these cranes do not have a moveable 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.The considerations are the mass the crane can handle as well as its stability.
