Common types of tower cranes

The tower body of the upper slewing tower crane does not rotate, and the rotating part is installed on the upper part. It is currently the most commonly used tower crane on construction sites. The characteristics of the upper slewing tower crane are: the bottom contour size is small, and the space requirement for the building site is small, which does not affect the use of the building material storage yard; Due to the tower body not rotating, the moment of inertia during rotation is small, the lifting capacity is relatively large, and the lifting height is relatively high, making it easy to modify into an attached tower crane, which can be suitable for the construction needs of various forms of buildings.
