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.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.The Romans used cranes to build large monuments; medieval churches were also constructed with the aid of cranes.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.The platform of a mobile crane may either have wheels that are designed for railroad tracks or caterpillar tracks.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.Truck mounted cranes and rough terrain cranes are also essentially mobile too.The truck-mounted crane will have outriggers to keep the crane fully stabile 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.Loader cranes are made up of hydraulic powered booms that are fitted on to trailers, they load goods onto the trailer and the joints of the boom are folded when not in use.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.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 base of the crane looks like a long ladder and the boom is perpendicular to the base.These cranes are often used for sky scraper construction and the build of tall buildings.
