One-Stop Rigging & Wire Rope Solutions for Global Engineering Projects

GN Ocean Engineering Equipment Group is a professional enterprise specializing in the design, production, and manufacturing of wire ropes, rigging, large structural components, and related rigging accessories for marine engineering, deep-water construction, shipbuilding, aerospace, energy construction, large-scale construction, and mining engineering projects. The group has divisions for wire rope, wire rope rigging, steel structures, and forging. Our specialty is manufacturing large-diameter, long-length, and custom-specification rigging products.Meanwhile, the company maintains a year-round inventory of imported steel wire ropes and imported accessories, as well as other specialized equipment products. The lifting products manufactured by our company and the imported marine engineering equipment we represent have received unanimous praise from users in various industries across China.The group has a nationwide production capacity network, with a 35-acre modern production base in Tianjin, capable of comprehensively meeting the customized processing needs of various marine engineering projects, docks, offshore engineering vessels, and wind power installation vessels for wire ropes and rigging. This demonstrates the group’s commitment to deepening its presence in the marine engineering sector and empowering industrial upgrading. In 2023, the group strategically invested in the Tongzhou Bay River-Sea Inter modal Development Demonstration Zone in Jiangsu Province, establishing a new 80-acre intelligent industrial line and simultaneously adding three core business divisions: marine engineering wire rope, marine engineering steel structure, and forged rigging. Leveraging its long-standing experience serving high-quality customers and understanding market trends, the group precisely completed capacity expansion and industrial structure upgrades, comprehensively enhancing its core supply capabilities and overall service strength in both the north and south of China.The company currently has 160 employees and has established a comprehensive R&D system and professional technology center. Among them are 30 core technical personnel, including 3 senior engineers and 5 professional engineers. All core technical staff have over ten years of industry experience. With its profound technological foundation, stringent quality control standards, and continuous innovation capabilities, the company’s overall strength and industry influence consistently rank among the top in the industry, earning high recognition from the market and customers.With the vigorous development of offshore oil and gas engineering, wind power engineering, and port industries, the demand for wire rope slings has increased significantly. At the same time, the localization of wire rope production is accelerating. Considering these factors, in August 2022, the company completed the acquisition of a professional wire rope sling manufacturer with twenty years of production history. Leveraging the leading advantages of this company’s professional technology and equipment, the company has filled several gaps in domestic high-end sling products in areas such as sling casting, pressing, and large-diameter seamless rope loop weaving, entering the fast lane of high-end sling manufacturing.The company has passed ISO9001 quality management system certification, ISO14001 environmental management system certification, ISO45001 occupational health and safety management system certification, China Classification Society (CCS) factory approval, and American Bureau of Shipping (ABS) factory approval in the field of rigging, becoming a professional rigging and lifting equipment manufacturing company that integrates R&D, production, sales and product testing.The company’s existing high-performance seamless rope loop weaving equipment and 2500T ultra-long horizontal tensile testing machine have been widely used. In addition, the company has built the largest frameless 5000T tensile testing machine in China in its Jiangsu plant. After it is put into use, the company will jointly establish a mechanical testing and experimental center with Shanghai Jiao Tong University. The center will provide ultra-large tonnage, extreme performance verification, reliability assessment and quality certification services for high-end marine equipment such as offshore platforms, wind turbine towers, deep-sea anchor chains and large steel structures in the Yangtze River Delta region and coastal areas. This will ensure that the equipment complies with international standards such as CCS and DNV, and help promote the demonstration application and market promotion of high-end equipment.The company plans to further increase investment, using Jiangsu as its headquarters, and to build professional rigging production bases and steel structure lifting equipment production bases in the Yangtze River Delta region and the Guangdong-Hong Kong-Macao Greater Bay Area. Its products will cover eight major categories, including steel rope products, seamless rigging, photovoltaic lifting beams, substation lifting beams, hooks, lifting tools, chain rigging, soft slings, clamps and clamps, lifting equipment, and rigging accessories. These products will serve a wide range of important industries such as deep-sea construction, wind power, petroleum, metallurgy, machinery, construction, power, ports, mining equipment installation, and bridge construction. The company aims to complete its development plan to become a benchmark enterprise in the domestic rigging industry as quickly as possible.The development of an enterprise cannot be separated from the support of its users. Adhering to the business philosophy of “quality first and integrity foremost”, the company aims to provide customers with the highest quality products and the most satisfactory services, and continues to move forward to meet and exceed customer needs!

18*k7 Anti-rotation Compacted-strand Steel Wire Rope

8X61M steel wire rope

Round-strand point-contact wire rope: In this type of rope, all wires within a strand—with the exception of the centre wire—have the same diameter. The lay lengths of adjacent layers differ, and the wires in adjacent layers within the strand make contact only at specific points; this type of rope is also known as a non-parallel-lay wire rope. The wires within the strand are arranged concentrically, with a difference of six wires between adjacent layers. These ropes offer good flexibility and are predominantly used for small diameters (under 10 mm) and large diameters (over 60 mm), as well as in applications such as lifting and lashing where ease of handling is a consideration.

Round-strand wire rope

Wire ropes in which adjacent layers of wires within a strand are in line contact are also known as parallel-lay wire ropes. The strands are formed by twisting wires of various specifications; the pitch of the wires in each layer is the same, but the lay angle varies. Depending on the arrangement of the wires within the strand, line-contact wire ropes are classified into four types: Walentin, Sill, filled, and Walentin-Sill. In line-contact wire ropes, not only do the wires within the same layer make line contact, but adjacent wires also make line contact; furthermore, the wires in each layer of the strand have the same lay direction (see Wire Rope Laying Methods) and pitch.
