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. The Romans used cranes to build large monuments; medieval churches were also constructed with the aid of cranes. This article aims at looking at the complex as well as simple ways of using cranes.
One simple crane is the mobile crane; this crane has a telescopic boom that is mounted on a movable platform. A mobile crane has a hook at its end while levers and pilly raise the cranes boom. 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. 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.
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. 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. When offloading awkward containers or unloading ships floating cranes can also be used.
Tower cranes are commonly used for crane hire, yet these cranes do not have a moveable base. When it comes to constructing this kind of crane, it is done so step by step as they are very tall. When it comes to its shape, its base is like a long ladder while its boom is perpendicular to this base. Tower cranes are designed in that they can aid the construction of very tall buildings as well as the sky scrapper buildings. There are generally two major things to be considered .the first consideration is that the stability it has and the specified mass.
