Gantry Portal Harbour Crane Run Along The Crane Tracks On The Ground Or Buildings For Lifting Loading And Unloading

The gantry crane has developed with the development of the port industry. In 1890, the first fixed and rotatable boom type crane with an adjustable amplitude was installed on a running semi gantry crane spanning over a narrow dock, becoming an early port semi gantry crane. As the width of the dock increases, gantry and semi gantry cranes are developed in parallel, and pitch arm frames and horizontal amplitude systems are commonly used. After World War II, the use of gantry cranes in ports rapidly developed to facilitate parallel work of multiple cranes on the same ship. The commonly used gantry crane is a revolving gantry crane with a rotating part connected to the column body (Figure 1 [revolving gantry crane]), or a rolling bearing type supporting rotating device with a large bearing connected to the gantry to reduce the tail diameter of the rotating part. A gantry structure with a reduced pier cover surface (the projection of the gantry body on the ground) is also adopted. In the process of development, gantry cranes have gradually been promoted and applied to shipyards and hydropower construction sites with operating conditions similar to ports.

Lucheng Co., Ltd. is mainly engaged in the design, manufacturing, installation, maintenance and renovation of single beam cranes, steel structure workshops, port cranes, double beam cranes, gantry cranes, grab cranes, variable frequency cranes, explosion-proof series cranes, chain oil scrapers, foam scrapers, and electric hoists.

In recent years, the company has continuously expanded its scale, with a significant increase in output value and profits and taxes, with an average annual growth rate of 42%. Its products are popular in 30 provinces and cities across the country, and are exported to African countries such as Nigeria. Among them, there are 2 × 250t variable frequency speed regulating cranes in the reconstruction area of Baishan Hydropower Plant and Yunfeng Hydropower Plant, and 300/20t variable frequency speed regulating cranes in the reconstruction area of Taipingwan Hydropower Plant, which were praised by Japanese Yaskawa and Sanling companies and users. The National Hydropower System Promotion Conference was held. The 100t variable frequency crane manufactured for Mount Taishan Nuclear Power Plant, and the 200/50t double beam bridge crane manufactured by China Erzhong Group were delivered to users after national acceptance. They were highly praised by the national testing agency and Erzhong Group. The transformation of energy-saving circulating sewage treatment equipment for Karamay is the pursuit of Tianyuan people, with unlimited integrity, supreme quality, and user satisfaction!
