1. Tower body: The tower body is the main supporting structure of the crane, usually composed of steel components, with sufficient height and stability to bear and disperse the weight and workload of the crane.
2. Hydraulic or electric system: The crane drives the lifting mechanism, slewing mechanism and walking mechanism through a hydraulic or electric system to achieve the lifting, rotation and walking of the goods.
