How cranes get on top of the building🤔

How you ever wondered how cranes get on top of buildings?
Cranes are one of the most common construction machinery. Without cranes, the construction of high-rise buildings would be nearly impossible.
When it comes to building skyscrapers, there is no piece of construction equipment more essential than a tower crane.
They play a pivotal role in the construction industry, facilitating the movement of heavy materials, equipment, and workers at elevated heights.
You've probably seen these massive cranes on the building but how do they get up there?
Its called the internal method, when a crane is employed on top of a high-rise building from within the construction site.An actual or a makeshift corridor is created in the center of the building.
At first, crane foundation is secured to the concrete foundation. Additional saction then stack on top of another.
As additional floores are added to the building, the hudrolic sillender is pressuresed to lift the crane upwards.
