Derrick Crane is a type of crane used in construction and industrial settings. It is a type of Tower Crane that has a pivoting arm, called a jib, mounted on a vertical tower. The jib can be rotated to move materials horizontally, and the crane can also lift heavy loads vertically. Derrick cranes are often used in building construction to lift and move heavy materials, such as steel beams and concrete blocks, to different levels of a construction site. They are known for their stability and ability to handle heavy loads.
Derrick crane, also known as Roof Crane, is a specific style of lifting machine. It is usually a fixed building crane, meaning it is assembled and disassembled in the location where it is used. Generally, the crane is characterized by its long, fixed length tower. These cranes are typically used in locations where items need to be moved from a common initial point to single nearby location, like on shipping platforms and construction sites.
