A large spider crane is an example of a heavy lifting machine used in large scale projects such as construction and requires significant lifting power and exceptional maneuverability in challenging conditions. This device has extendable legs that provide stability on confined spaces, which give the device its spider-like appearance. Depending on the model, these cranes carry substantial loads, which range from several tons to 100 tons. With advanced hydraulic systems and control mechanisms, large spider cranes enable reliable movement and positioning of heavy objects. They are regularly used in construction of large buildings, bridges, industrial plants, and shipyards where they are needed due to their ability to work in small, hard-to-reach, and complicated sites.
