In August 2009, Jiuyuan Company established a project to study the rotary spreader project. On the basis of drawing on and absorbing foreign advanced technology, combined with the actual situation of domestic shipbuilding enterprises, after half a year of independent research and development, Jiuyuan Company has optimized and optimized the design, and developed products that are more suitable for domestic practical use, cost-effective and reliable quality. . The spreader is fully applicable to the large, integrated and efficient construction process mode of the modern shipbuilding industry. The rotation angle is convenient to control and the alignment is accurate. It can meet the requirements of the hull sectioning and positioning adjustment angle, and has wide applicability in operation. At the same time, the spreader has a simple structure, strong carrying capacity, automatic rotation, good stability, strong ability to withstand changing loads, and safe and convenient use.
The large rotary spreaders designed and manufactured by Jiuyuan Company mainly have 700 tons (double hooks) and 500 tons (single hooks), which have been put into use in Nantong COSCO Kawasaki Ship Engineering Co., Ltd. and Nantong United Heavy Industry Technology Co., Ltd. respectively. This type of product is designed and manufactured for the first time in China. At present, Jiuyuan Company has applied for the invention patent of single hook rotary spreader for large crane lifting.
