1. Up-rotating Wholesale QTD 160 tower crane: The tower body does not rotate, and the boom, balance arm, etc. above the slewing bearing are fully rotated around the center line of the tower body through the slewing mechanism. According to the requirements of use, it is divided into running type, fixed type, attached type and inner climbing type. The running Wholesale QTD 160 tower crane can run along the track, has a large working range and a wide range of applications, and is suitable for multi-storey building construction; if the crane base is fixed on the track or the tower body is directly fixed on the foundation, it becomes a fixed type, Its boom is long; if the fixed tower is connected to the building with an attachment rod at a certain height, it is an attached type. It adopts a tower body height connection device so that the upper part of the crane can be increased correspondingly with the height of the building. It is used for high-rise building construction; the crane is installed in the elevator shaft or other wellbore or connected holes, and the hydraulic cylinder is used to make the crane climb up along the wellbore according to the construction process. It has a large service area and does not occupy the construction site, but it has certain requirements for the structure of the building.

2. Lower rotary Wholesale QTD 160 tower crane: The slewing bearing is installed between the base and the turntable. Except for the traveling mechanism, other working mechanisms are arranged on the turntable to rotate together. In addition to the track type, there are also the crawler type and the tire type with the crawler chassis and the tire chassis as the running device. It has a low center of gravity, can be disassembled and transferred as a whole, light and flexible, widely used, and suitable for multi-storey building construction.
