how do cranes get to the top of buildings

Have you ever seen a tall building under construction and wondered how those huge cranes got to the top? It seems like an impossible task to lift such a massive object to such a great height. However, this is a common occurrence in the construction industry. In this article, we will explore the various methods used to get cranes to the top of buildings.

Using a Climbing Crane

One of the most common methods of getting a crane to the top of a building is by using a climbing crane. This is a type of crane that is designed to climb up the structure as the building grows taller. The process involves a large crane, called a 'base crane,' that is stationed on the ground. The base crane uses a special rigging system to hoist the climbing crane's mast and tower sections onto the building's roof. Once the tower sections are in place, the climbing crane hoists itself up the building using hydraulic cylinders and a climbing frame. This process is repeated until the crane reaches the desired height.

Using a Helicopter

Another method that is used to get cranes to the top of buildings is by using a helicopter. This method is usually used when there is limited space on the ground, or when the building is too tall for a climbing crane. The crane is disassembled into manageable sections, loaded onto a flatbed truck and transported to a suitable location. A helicopter is then used to lift each section of the crane to the top of the building and assemble it in place.

Using a Crane-Lifting Dolly

A crane-lifting dolly is another method used to lift cranes to the top of buildings. The dolly is a special piece of equipment designed to transport cranes from one location to another. It consists of a wheeled platform that is connected to a hydraulic lifting system. To get the crane to the top of the building, the dolly is first loaded with the crane's individual parts. It is then hoisted up the side of the building using the lifting system. Once the dolly is close enough to the top, the crane parts are assembled in place.

Conclusion

In conclusion, there are several methods used by construction companies to get cranes to the top of buildings. Each technique has its pros and cons, and the choice of method depends on various factors such as the building's height, space restrictions, and budget. Whether it's a climbing crane, helicopter, or crane-lifting dolly, rest assured that construction companies have perfected the art of getting cranes to the top of buildings.
