A tower crane is a fully slewing jib crane with a tower-like structure, serving as essential equipment for large civil engineering construction sites. These cranes efficiently transport construction materials and machinery, performing vertical and horizontal movements to complete material handling tasks quickly and effectively.
Standard tower cranes typically reach heights equivalent to 10 stories, featuring a lifting mechanism at one end, an operator control room in the middle, and a substantial concrete counterweight at the opposite end to maintain operational balance.
As a modern evolution of balanced cranes, tower cranes incorporate similar fundamental components. They are securely fixed to concrete foundations (sometimes attached directly to building structures) and offer optimal combinations of height and lifting capacity for high-rise construction projects. The base connects to the mast, which determines the crane's working height, while the mast connects to a slewing unit containing gears and motors that enable full rotation capability.
The strategic positioning of tower cranes on construction sites significantly impacts project material transportation efficiency and overall costs.
