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. Here in this article we shall look at the simple and complex uses for cranes.
A mobile crane is the first kind of a crane that has a telescopic boom on its movable platform. Pulleys or levers will raise the boom of this crane, usually a hook will be found at the end of this crane. When working in the city to move heavy equipment’s, mobile cranes are the best option as they offer convenience. 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 stable when in use. Moreover, those terrains that are designed for rough terrains are just like a four wheel drive.
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.
However, those in the shipping industry would need to buy the floating cranes for flexibility while loading cranes. When building ports and salvaging ships, floating cranes are the best as they can operate in water. 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. When it comes to constructing this kind of crane, it is done so step by step as they are very tall. 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. When deciding on the design of the crane it is generally based on two major things.The considerations are the mass the crane can handle as well as its stability.
