Product Overview

EN 818-2 Grade 100 Chain for Heavy-Duty Lifting

Grade 100 lifting chains are high-strength alloy steel short-link chains manufactured to EN 818-2, GB/T 20947-2007, and ISO 3077, designed for smelting, shipbuilding engineering, and extreme-duty industrial lifting where Grade 80 chains are insufficient. The G100 designation corresponds to a minimum tensile strength of 1,000 MPa per link ring, achieved through precision braiding and multi-stage heat treatment of 23MnMoNiCr54 Und 20CrNiMo special alloy steel.

Ever-power Engineer Class Chain Co., Ltd produces G100 chain in diameters from 6 to 26 mm, covering working load limits from 1,400 kg (6 mm) to 21,200 kg (26 mm). All chains undergo 6-metre dynamic load testing at 2–2.5× working load and a 4× safety factor verification. Each link is permanently stamped with the G100 grade mark for lifecycle traceability.

Surface treatment options include galvanising and immersion lacquer coating for corrosion resistance. Chains are suited to harbour giant cranes, deep-shaft rescue equipment, and nuclear facility modular lifting systems where strict safety margins are mandatory.

Construction & Standards

Produktmerkmale

Standards: EN 818-2 · GB/T 20947-2007 · ISO 3077

Manufactured and tested to three concurrent international standards. EN 818-2 governs dimensional tolerances and mechanical properties for lifting chain. GB/T 20947-2007 and ISO 3077 provide additional verification requirements for high-grade chain used in critical lifting environments.

Material: 23MnMoNiCr54 / 20CrNiMo Special Alloy Steel

High-strength special alloy steel grades are used to achieve the 1,000 N/mm² minimum tensile class required for G100 designation. Both alloys provide the combination of tensile strength, ductility, and impact toughness necessary for dynamic lifting duty.

6 m Dynamic Load Testing

Each chain undergoes a 6-metre dynamic load test at 2–2.5× working load, in addition to 4× safety factor breaking load verification. This replicates the load cycles experienced in real lifting operations more accurately than static proof testing alone.

G100 Permanent Link Marking

Every link is permanently embossed with the G100 grade designation and manufacturer code at regular intervals. Marking enables in-service inspection, grade confirmation, and full lifecycle quality traceability without chain removal from the sling assembly.

Size Range: 6 to 26 mm

Twelve standard diameters from 6 to 26 mm cover working load limits from 1,400 kg to 21,200 kg. The range addresses both light crane sling assemblies and the heavy-duty end of the G100 application spectrum.

Surface Treatment Options

Available with galvanising or immersion lacquer coating. Treatment is selected according to the corrosive exposure expected in the operating environment, including outdoor, marine-adjacent, and high-humidity industrial locations.

Häufig gestellte Fragen

What is the difference between Grade 100 and Grade 80 lifting chain?

Grade 100 chain has a minimum tensile strength of 1,000 N/mm², compared to 800 N/mm² for Grade 80. At the same nominal diameter, a G100 chain carries a higher working load limit than a G80 chain. G100 also uses different alloy steel grades (23MnMoNiCr54 / 20CrNiMo) and undergoes 6-metre dynamic load testing rather than static proof testing.

What standards does Grade 100 chain comply with?

Ever-power G100 chains are manufactured and tested to EN 818-2, GB/T 20947-2007, and ISO 3077. These three standards together define dimensional tolerances, material requirements, mechanical property verification, and dynamic load test procedures for Grade 100 lifting chain.

What is the working load limit for 16 mm Grade 100 chain?

The working load limit for 16 mm G100 chain is 10,300 kg. The dynamic test load is 201.0 kN and the minimum breaking load is 402 kN, providing a 4:1 safety factor relative to the WLL.

How is Grade 100 chain tested before dispatch?

Each chain undergoes a 6-metre dynamic load test at 2–2.5× working load limit, and a minimum breaking load verification at 4× WLL. Each link is also permanently stamped with the G100 mark for lifecycle traceability. Test certificates are available on request.

When should I specify G100 instead of G80?

Specify G100 when the required working load limit at a given chain diameter cannot be met by G80, or when the application involves strict safety certification requirements (nuclear facility lifting, deep-shaft rescue, classification society-approved marine crane systems) that mandate the higher tensile class and dynamic test protocol.

What certifications does Ever-power hold?

Ever-power Engineer Class Chain Co., Ltd holds ISO 9001, ISO 14001, Lloyd's Register, ABS, Bureau Veritas, DNV, CE, and ASME Planner approvals. Certificate copies are provided during the enquiry process.
