How is a tower crane assembled?
It all starts with the tower crane’s foundation, which is important because it ensures the crane stays in place. The foundation includes deep foundation piles and a concrete block.
Once the foundation is completed the first part of the tower is built. To do that, crews take tower sections called masts and bring them together to create the base. This part is completed with a crane; the first mast is what you see in the picture to the right. After the initial part of the crane is done, they will install the climbing unit. The climbing unit will allow the crane to build up later in the process.
The slewing assembly is the next phase. This section is the horizontal section of the crane and can be assembled separately and then lifted onto the base with a crane.
Lastly, the crane can be made taller by using the climbing unit and a hydraulic jack.
And, that is how a tower crane is built.

Construction crews have been busy working on the deep foundation for the new tower.
What is a deep foundation?
First, let's talk about a foundation. A foundation creates a stable, solid base for a building. A deep foundation is used when the load-bearing soil or rock is deep below the surface. It transfers weight from a building's upper layers to stronger soil or rock layers below. In short, it distributes the weight over a larger area and prevents excessive settlement or movement that could compromise the structure's stability and integrity.
Pile foundations are the most popular deep foundations and what our crews are currently installing. They are made of columns of concrete reinforced with steel rebar.
