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. 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. A mobile crane has a hook at its end while levers and pilly raise the cranes boom. working in the city requires great flexibility, it is therefore good to use a mobile crane to do so as it has great convenience. Moreover, the platform of a mobile crane may either be fitted with caterpillar trucks or even wheels for a rail road.
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. Truck mounted cranes and rough terrain cranes are also essentially mobile too. 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.
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. When building ports and salvaging ships, floating cranes are the best as they can operate in water. The floating cranes can be used to offload awkward looking containers as they are just designed to do this.
The other type of cranes is the tower cranes, they however, do not have a movable base. when constructing the crane, it has to happen base by base as they are very tall. The base of the crane looks like a long ladder and the boom is perpendicular to the base. Tower cranes are designed in that they can aid the construction of very tall buildings as well as the sky scrapper 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.
