Flat-top tower cranes are generally used in construction sites or bridge construction sites. The position of the hook is controlled by boom rotation and the distance of the trolley. It can lift objects in the turning radius. Compared with the flat-top tower crane with tower head and tie rods, The mechanical model of the boom is simple and clear, because there is no tower head and the installation height is low, which makes the installation faster and safer. Suitable for large-scale construction needs.
