With the development of tower crane technology, the density of urban buildings is gradually increasing.

According to the current development trend of the construction industry, the demand for luffing  self-climbing tower cranes is increasing. This type of tower crane has small slewing radius at the tail end, which can effectively avoid collisions between the crane hoisting jib and surrounding buildings in demolition and reconstruction projects. It is suitable for narrow construction sites and can play its unique advantages in the construction of tower high-rise buildings. This type of tower crane has super large hoisting moment and wide working range, which is suitable for the construction needs of steel structure high-rise buildings and can fully play its advantages in the construction of tower high-rise buildings. The luffing self-climbing tower crane adopts new design of slewing platform mechanism, which can effectively improve the stress state and enhance the horizontal stiffness.
