A crane is a type of heavy equipment that is used to lift and move heavy objects. It typically consists of a tall, vertical mast with a jib or boom that extends horizontally. The boom is attached to a cable or chain that can be lowered and raised using a motor or winch. Cranes come in many different sizes and configurations and are commonly used in construction sites, shipping yards, and manufacturing plants.

Some of the most common types of cranes include tower cranes, mobile cranes and overhead cranes. These machines are capable of lifting and moving extremely heavy loads, making them essential tools for many industries. However, operating a crane requires specialized training and expertise to ensure safety and avoid accidents.
