The rim steel structure of the Ferris wheel is processed and assembled in sections in the factory. After transporting to the site, the rim is assembled into a whole, and then connected to the internal rigid truss support or flexible steel cable system, and then the overall hoisting position is carried out. The British 'London Eye' adopts this construction method. The steel tube truss of the wheel rim is divided into 3 sections and processed in the factory. It is transported to the site and assembled as a whole. Then the steel cable inside the wheel rim is installed and tensioned, and the prestress is introduced. After the roulette structure and the supporting tower structure form an integral structure, hoisting is carried out.
The ground assembly and overall hoisting method is conducive to the installation of the steel structure, and the installation accuracy is easy to ensure, but the scale and weight of the Ferris wheel are generally large, so a large construction site and strong lifting capacity are required.
The vertical rotation installation method of amusement equipment manufacturers refers to the construction method in which the temporary rigid spokes are used to drive the segmented rims and steel cables to rotate and install after the support tower and the axle are installed. The vertical rotation installation method is divided into one-side rotation installation method and two-side rotation installation method. It is suitable for the flexible Ferris wheel structure system that relies on steel cables to provide centripetal force. This method has been used in Tianjin Cihai Bridge Ferris wheel structure.
The vertical rotation installation method of amusement equipment manufacturers can avoid a lot of high-altitude operations, and the risk is low; but it requires a large traction power system and a good braking system, especially the two-side rotation installation method also needs to do the center axle of the Ferris wheel. special handling.
According to the difference of the operating mechanism, the Ferris wheel can be divided into two types: the gravity Ferris wheel (Ferris Wheel) and the observation wheel (Observation Wheel). The cockpit of the gravity Ferris wheel is hung on the wheel to maintain the level by gravity; while the cockpit on the observation Ferris wheel is suspended outside the wheel, which requires a more complex mechanical structure of connecting rods, and the position of the car revolves around it. to synchronously adjust its hold level.
