how do cranes get on top of buildings

Cranes are big, tall machines that are commonly used in construction sites. They are known for their ability to lift heavy materials and transport them to different parts of a building. However, one question that comes to mind is how these cranes reach the top of a building? In this article, we’ll explore different ways in which cranes are placed on top of buildings.

Tower Cranes

Tower cranes are commonly used in construction sites. They are designed to be erected at the beginning of a project and remain stationary until the project is completed. Tower cranes are assembled in sections on the ground, and as each section is completed, it is lifted to the top of the building using another crane. This process continues until the final section is lifted and secured into place. Once the tower crane is in place, it can reach up to 265 feet high, has a lifting capacity of up to 20 tons, and can rotate 360 degrees.

Mobile Cranes

Mobile cranes are another type of crane used to lift and transport heavy materials. However, unlike tower cranes, mobile cranes are built on wheels and can travel from one location to another. They are commonly used in smaller construction projects where space is limited. To get a mobile crane on top of a building, it is usually carried up using a larger crane. The mobile crane is first disassembled and transported to the construction site. Once the larger crane lifts it to the top of the building, it is reassembled and then used for lifting and transporting materials.

Helicopter Transport

In some cases, cranes are transported to the top of a building by helicopter. This method is used when there is no space or access for a crane to be erected on the ground. It is a dangerous and expensive method and is only used when all other options have been exhausted. The crane is first disassembled and transported to the nearest airport. Once there, it is loaded onto a helicopter and flown to the construction site. Once the helicopter reaches a safe height, the disassembled crane is released and lowered onto the top of the building. This method requires a highly skilled pilot and precision planning to ensure the safety of everyone involved.

Conclusion

Cranes are essential equipment in any construction project. The question of how they are placed on top of a building is one that many people wonder about. Tower cranes are commonly used and can be easily assembled on the ground and then lifted to the top of the building using another crane. Mobile cranes are another option but require disassembling, transporting, and reassembling. In extreme cases, helicopters are used to transport cranes to the top of a building. Regardless of the method used, safety is always a top priority.
