Luffing tower cranes are a type of Tower Crane commonly used in construction projects. Unlike traditional tower cranes, luffing tower cranes have a jib that can be raised or lowered to adjust the height and reach of the crane. This allows them to work in tight spaces or in areas with height restrictions.

Luffing tower cranes are especially useful in urban environments where space is limited. The ability to adjust the jib angle allows the crane to work around obstacles such as buildings or other structures. They are often seen on high-rise construction sites, where their versatility and compact design make them ideal for lifting and moving heavy loads.
The luffing mechanism of these cranes allows for precise control over the load, making them suitable for projects that require delicate or precise movements. They are also known for their quick and efficient operation, with the ability to lift heavy loads to great heights in a relatively short amount of time.
Overall, luffing tower cranes are a valuable asset in the construction industry, providing flexibility, efficiency, and safety in various construction projects.
