how are construction cranes removed

Construction cranes are an essential part of modern construction. They help in lifting and moving heavy materials, equipment, and machinery. However, once the construction work is over, these cranes become a hindrance and can lead to accidents or traffic congestion. Therefore, it is essential to remove them safely and efficiently. We will examine how construction cranes are removed in this article.

Types of Construction Cranes

Before we dive into the process of removing construction cranes, we should know the types of cranes used in construction. There are several types of construction cranes, such as tower cranes, mobile cranes, crawler cranes, and telescopic cranes. Each crane has its unique lifting capacity and is used for specific purposes. The type of crane used in construction determines how it can be removed.

Removal of Tower Cranes

Tower cranes are commonly used in high-rise construction projects. These cranes are erected at the beginning of the project and remain in place throughout the construction process. Removing a tower crane involves several steps. First, the crane's counterweights and the ballast block are removed. Then, the jib (the horizontal arm of the crane) is lowered and dismantled. Finally, the mast sections are taken down using a mobile crane or another tower crane. The process of removing a tower crane takes several days, and it requires skilled workers and specialized equipment.

Removal of Mobile Cranes

Mobile cranes are versatile and can move from one site to another quickly. These cranes are commonly used for short-term projects, such as road construction or bridge repairs. Removing a mobile crane is relatively simple. First, the crane is lowered to the ground. Then, it is placed on a trailer that is hitched to a truck. The trailer is then driven away to another site where the crane will be used.

Removal of Crawler Cranes

Crawler cranes are used in rugged terrains and heavy lifting projects. These cranes have tracks instead of wheels, making them more stable. Removing a crawler crane involves several steps. First, the crane is dismantled, and the different components are loaded onto trucks. The tracks and body of the crane are then transported separately. The process of removing a crawler crane is time-consuming and requires skilled workers and specialized equipment.

Conclusion

In conclusion, construction cranes are essential equipment in modern construction. However, once the construction work is over, these cranes need to be removed safely and efficiently. The removal process depends on the type of crane used in construction. Skilled workers and specialized equipment are required to safely remove these cranes. Proper planning and execution of the removal process can prevent accidents and ensure smooth traffic flow.
