CRANES 101 EXPLAINED.

Various kinds of cranes are available for hire and it is important to understand all of them. Cranes are designed predominately to move weights with levers or pulleys, although they may look modern they have been used for the last 2000 years. Romans were the first people to use cranes while building monuments as well as churches. Cranes have both simple and complicated means of use and we are going to look at them.

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.
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. 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. They are fairly similar to telescopic cranes as on some sections of this type of crane there may be a section of the boom that uses telescope of easier use.

It is important that those that are in the shipping industry hire the floating cranes as they are suitable for this purpose. They are situated in water and are usually used for the construction of ports, to salvage ships or to aid with building bridges. 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. When it comes to its shape, its base is like a long ladder while its boom is perpendicular to this base. These cranes are often used for sky scraper construction and the build of tall 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.
