A derrick is a type of crane used for lifting heavy loads, commonly found in construction and industrial settings. It consists of a tall framework that supports a hoisting mechanism, allowing it to raise and lower materials with precision. Derrick cranes are often used in the oil and gas industry for drilling operations, as well as in shipping and construction projects. Derricks can vary in design, but they typically feature a pivoting arm, known as a boom, which can extend and retract. They are essential for tasks that require moving heavy equipment or materials, making them a vital tool in many sectors, including construction, mining, and shipping.
