从China供应商批发进口Alloy Steel Swivel Type Lifting Hoist Ring G80 — FOB条款

Tianjin Yiyun Rigging Co., Ltd. manufactures G80 grade swivel type lifting hoist rings from forged alloy steel, with thread sizes ranging from M6 to M100. The product conforms to EN 1677-1 (the supplier states EN1672, which appears to be a typographical reference to the European standard for lifting components) and is certified to ISO9001, ISO14001, CE, SGS, CCS, HSE, and OHSAS standards. Alternate product names include weld on hook, weldable hook with latch, excavator universal weld on hook, pivoting D link, attachment point, flat point, attachment swivel, lashing point, pivot link, swivel lifting point, and adjustable bolt. The forged alloy steel construction provides the strength-to-weight ratio required for critical lifting operations in construction, manufacturing, and heavy equipment sectors.

G80 grade indicates a minimum breaking strength of 800 MPa for the lifting chain system, with the hoist ring itself typically achieving a safety factor of 4:1 or 5:1 against the working load limit. The swivel mechanism allows 360-degree rotation and often 180-degree pivot, reducing torque stress on the lifting assembly during load manoeuvring. Thread sizes from M6 to M100 cover working load limits from approximately 0.4 tonnes to over 100 tonnes depending on design factor and thread engagement length. The forged alloy steel material undergoes quenching and tempering to achieve the required mechanical properties, with typical surface treatments including zinc plating or hot-dip galvanising for corrosion resistance, though buyers should confirm the exact finish offered by Tianjin Yiyun Rigging.

Primary applications include permanent attachment points on machinery, vehicles, and structural steel where repeated lifting is required; the weld-on variants serve as fixed lifting points on excavator booms, crane components, and fabrication jigs. Buyers include construction equipment manufacturers, offshore rigging contractors, shipbuilders, and heavy machinery maintenance facilities. The threaded swivel type suits applications where the load direction changes during the lift, as the bearing assembly prevents rotation from transferring to the bolt. For import transactions, buyers should confirm with Tianjin Yiyun Rigging whether the quoted product includes the bolt, nut, and washer assembly or requires separate procurement, and whether the certification package includes material certificates and test reports per EN 10204.

Tianjin Yiyun Rigging Co., Ltd. is located in Dongli Zone, Tianjin, China. The company specialises in lifting and rigging hardware, with its product portfolio centred on G80 alloy steel swivel hoist rings and related attachment points. Its trust tier is listed as harbor, with a response rate of 0.00 % and average response hours recorded as zero, indicating that direct communication to confirm product details and lead times is essential. The supplier holds multiple certifications including ISO9001, ISO14001, CE, SGS, CCS, HSE, and OHSAS, which cover quality management, environmental management, European conformity, and occupational health and safety systems.

The supplier profile does not state year of establishment, factory floor area, number of employees, annual production capacity, or specific client projects. Dongli Zone in Tianjin is an established industrial area with access to port facilities and logistics networks serving northern China's manufacturing belt. Buyers should verify whether Tianjin Yiyun Rigging operates as a manufacturer with forging capability or as a trading company sourcing from sub-contractors, as this distinction affects quality control traceability and certification validity. The broad thread size range from M6 to M100 suggests either substantial forging capacity or a supply chain with multiple production sources.
