Types of Cranes Used in the Construction Industry

From as far back as the Mesopotamian civilization, cranes have been used for lifting objects that are too heavy or too repetitive to be done manually. Since this type of work is very much used in the construction industry, the use of cranes in it has been invaluable and indispensable since the ancient era. From the ancient Shadouf to roman Polyspastos to modern mobile telescopic cranes, they were used pretty much everywhere on earth.

What is a Crane?

A crane is a machine, comprised of beams, cables, and pullies, which is used to lift or lower heavy objects. An appropriately equipped crane may also move objects horizontally as well as vertically. The mechanism can be supported by a tower or a derrick.

Most cranes used in construction are temporary structures or even mounted on mobile platforms so that they can be moved around the construction site as necessary. They can be taken away when construction finishes in order to leave the site for normal usage. In some cases, where the building in question requires constant maintenance, the engineers may choose to rig a permanent crane with the building.

Modern cranes are powered by means of hydraulics that are driven by an electric motor or a combustion engine driven by fossil fuel. Operating (and driving, in case of mobile cranes) the crane is possible from an operators cabin that may be mounted on crane vehicle or rig itself, or a control station beside the crane, or by means of portable radio-operated controllers that gives the crane operator the freedom to move around and see the loading and unloading operation from any reasonable point of view. Taking that flexibility to a newer level, there are some modern cranes available that can even be controlled via mobile phone apps.

Types of Cranes in Building

Depending upon their usage, flexibility, and mobility, there can be several types of cranes to choose from to use in a construction site. The varieties of choices enable the constructor to adapt to any load-lifting requirements on site. Let us see what they are.
