Cranes lift themselves higher using a process called "climbing." They have a system of hydraulic jacks that extend and elevate the crane's mast. As the crane raises itself, it adds sections of its mast to increase height, allowing it to reach higher levels of construction. This self-climbing capability is crucial for working on tall structures efficiently.
