Construction cranes are tall, tower-like machines used to lift and move heavy materials on construction sites. They are essential for building structures like skyscrapers, bridges, and homes. Cranes can reach great heights and are equipped with a long arm, called a boom, that extends to pick up and place heavy loads. There are different types of cranes, including tower cranes, mobile cranes, and crawler cranes. Each type is designed for specific tasks and environments. For example, tower cranes are fixed to the ground and are ideal for tall buildings, while mobile cranes can move around the site to perform various lifting tasks.
