Torninosturi

Torninosturi, commonly known as a tower crane, is a modern construction machine used for lifting and moving heavy materials on construction sites. These cranes are characterized by their tall, vertical mast and a horizontal jib or boom that rotates 360 degrees. This design allows them to reach significant heights and cover a large working radius, making them indispensable for the construction of tall buildings and structures.

The basic components of a tower crane include the mast, which provides the height, the luffing jib or hammerhead jib, which extends horizontally, and the operator's cab, usually located at the top. A counterweight is also essential, positioned on the opposite end of the jib to balance the load being lifted. The crane operates through a system of motors and pulleys that control the hoisting, slewing (rotating), and luffing (raising or lowering the jib) movements.

Tower cranes are typically assembled on-site using smaller cranes, with sections of the mast and jib being added incrementally as the building grows taller. They are a crucial piece of equipment in urban construction, enabling the efficient and safe placement of concrete, steel, and other building materials at great heights. Their prevalence in skylines worldwide attests to their importance in modern architecture and engineering.
