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. 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. 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. 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. the loader cranes are similar to hydraulic cranes as they are all fitted with telescopic booms for easier use.
It is important that those that are in the shipping industry hire the floating cranes as they are suitable for this purpose. The floating cranes are suitable they can operate in water while building salvage ships, ports as well as supporting 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 boom of this crane is perpendicular to the base of the crane in order to make it more stable. This kind of cranes are used for constructing sky scraper buildings or generally very 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.
