Cranes – Integral Part of the Construction Industry
Cranes are extremely valuable assets in the construction industry as they simplify working with construction materials and heavy equipments. A crane is basically a lifting machine, which works with the help of cables and pulleys. Cranes have drastically made things easy for workers on the construction site since without these machines, lifting, unloading and loading had to be carried out manually. Cranes have enabled workers to work more efficiently than before. Different types of cranes have been designed for different purposes. This article discusses briefly about the various types of cranes used in construction sites.
Tower crane is a common type of crane used in construction. This crane was invented in Europe and is now quite popular globally. The crane is used especially to construct tall buildings. The crane can reach up to a height of about 265 feet. It can extend up to about 230 feet and has the ability of lifting a total weight of about 20 tons. These cranes are usually fixed to the ground, when construction works are carried out. It is always mounted on a strong, concrete pad, in order to embed anchor bolts into the pad. These bolts hold the crane properly, when heavy loads are lifted using it.
Vehicle Mounted Cranes:
As the cranes employed on construction sites are temporary structures usually, they are sometimes mounted to vehicles. This is done so that the cranes can be moved easily. Truck-mounted cranes can usually travel on highways. Hence, no additional equipment is needed for transporting such cranes to the construction sites. During the erection of such cranes at the job site, you need to extend outriggers from the truck base horizontally and then vertically, for stabilizing the crane.
1. Rough Terrain Crane: A rough terrain crane is one of the special types of truck-mounted cranes. An undercarriage is used for mounting such cranes. The undercarriage consists of rubber tires meant to be used in off-road applications. Outriggers are also employed in this type of crane, for stability.
2. All Terrain Crane: All-terrain cranes are just perfect for industrial projects and for carrying out off-road and on-road constructions. These cranes can function irrespective of climate, temperature and location. All-terrain crane is reliable for meticulous maintenance purposes and also for new development works. These cranes have lots of useful and effective built-in frames, safety devices and digital displays forecasting different data during operation.
This is a type of mobile crane, which does not need outriggers for stability. In this type of crane, a chassis is used for mounting the crane. The chassis comprises a tracks set, instead of having tires. The lifting capacity of a crawler crane lies between 40 tons and 3500 tons. Though these cranes are mobile in a job site, but you need to disassemble them and load them on transport trucks to move them between construction sites.
A floating crane is also a mobile crane, which is used for the construction of waterways like dams, ports and bridges. Such cranes are usually mounted over special barges or pontoons.
These are the major types of cranes used for construction purpose. All these cranes have their individual features and specialize in a particular kind of job. Choose a crane type on the basis of the job you need to accomplish using the crane.
Summary: Cranes are widely used in construction sites. Different types of cranes are available for carrying out different jobs.
