how do they erect tall cranes

Cranes are one of the most important pieces of equipment in construction, and they come in all shapes and sizes. Tall cranes are particularly impressive, but how are they erected? In this article, we will take a closer look at the process of erecting tall cranes, step by step.

Preparation

Before the actual erection of the crane takes place, a number of important preparatory steps must be taken. First, the area where the crane is to be erected must be cleared of any obstacles, including trees, buildings, or other structures. Next, a solid foundation must be laid to anchor the crane. This usually involves pouring a large concrete pad, which will support the enormous weight of the crane. Finally, the crane components are delivered to the site and assembled in preparation for erection.

Erection Process

The erection of a tall crane is a complex process that requires considerable planning and coordination. Generally, the process involves building the crane piece by piece, one section at a time. The first step is to erect the base section of the crane. This is typically the largest and most complex part of the crane, requiring a large crane or other heavy equipment to lift it into place. Once the base is secured, the mast and boom sections are added, followed by the cab and jib.

Securing the Crane

Once the crane is fully erected, it must be secured to prevent any movement or swaying during use. This is achieved through the use of a series of large steel cables that are anchored to the base of the crane and run up through the mast and boom. These cables are tightened using hydraulic jacks to ensure that the crane remains stable at all times.

Testing and Certification

Once the crane is fully erected and secured, it must undergo a series of tests to ensure that it is functioning properly and can safely lift heavy loads. These tests include load testing, stability testing, and operational testing. Once the crane passes all of these tests, it is certified and ready for use.

Conclusion

The process of erecting a tall crane is a complex and intricate one, requiring careful planning and coordination. However, with careful attention to detail and a skilled team of workers, the end result can be a safe and reliable piece of equipment that is capable of lifting heavy loads and facilitating complex construction projects.
