Various kinds of cranes are available for hire and it is important to understand all of them. Most of us think that cranes are some modern discovery but they are not, they have been in use for more than 2000 years now. In the olden days, cranes were used to build medieval churches as well as monuments especially in Rome. This article aims at looking at the complex as well as simple ways of using cranes.
The first kind of crane is the mobile crane that has a telescopic booth 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. Moreover, the platform of a mobile crane may either be fitted with caterpillar trucks or even wheels for a rail road.
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. for the truck mounted cranes they have to be installed with outriggers to keep it stable. 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.

This kind of cranes are used for constructing sky scraper buildings or generally very tall buildings. There are generally two major things to be considered .the first consideration is that the stability it has and the specified mass.
