Construction cranes are valuable and essential properties for the construction industry. Cranes have some vital jobs on construction sites, especially when tall buildings, bridges, skyscrapers, etc. are constructed. Nowadays different types of constructions are done in odd places like in the middle of a river, or in a busy traffic area, where works can be smooth-sailing with the help of construction cranes.

Utility of construction cranes

Before cranes, construction industry worked differently as everything required human labor. Lifting, loading, unloading and shifting were done by laborers. It required lots of time and labor. The process was expensive too. The construction industry in many places needed to restrict their imagination and design due to lack of labor or expertise. These problems are readily solved ever since construction cranes were invented. It saves much time, labor and money of contractors or owners of buildings. Modern day construction cranes possess a huge capacity and a great many utilities.

Types of construction cranes

Various types of cranes are used depending on the requirements of the work and site location. Here are the mostly used construction cranes:

• Tower cranes – These cranes are required in building skyscrapers, bridges, and tall buildings. Tower cranes are normally fixed on the construction site with a strong base as long as construction works proceeds. They rise hundreds of feet above and can also reach out hundreds of feet horizontally. Tower cranespossess18-20 tons lifting capacity.
• Truck-mounted cranes – As the name suggests, these cranes are mounted on a vehicle and easily movable from one location to another. These cranes have two parts: the carrier where the crane is fixed which is also called lower, and the lifting component called upper. A truck-mounted crane possesses 13-14.5 tons capacity.
• Rough terrain cranes – It is a specialized form of thetruck-mounted crane where the tiers of the carrier are specially built for moving on an uneven surface. Outriggers are used in these cranes so that the system remains firm while loading and unloading. These cranes generally possess 35-80 tons lifting capacity.
• Crawler Cranes – A crawler crane is almost like rough terrain crane but it possesses crawlers or tracks for movement. The crawlers provide sufficient stability to this cranes, hence, they don’t come with outriggers. Crawler cranes possess high lifting capacity which starts from 40 tons.
• Railroad cranes – As the name suggest, these cranes are mobile but only on the railway tracks. They possess flanged when suitable for movement on the track. The lifting capacity of these cranes generally varies from 15-250 tons.
• Aerial cranes – These are the most modern addition to this product line. Aerial cranes are actually helicopters that carry loads to a great height or in an odd site like is a mountain site or in the middle of a river.

Besides, telescopic cranes, floating cranes, level luffing cranes, etc. are also used in different construction sites. Again, contractors may require more than one types of cranes to work simultaneously. Cranes make any construction work rather easy and inexpensive than manual or semi-manual works. However, proper training for operation and safety is required while working with the cranes.
