G80 Alloy Steel Lifting Chain
For demanding lifting and material handling applications, selecting the right chain is paramount for both safety and operational efficiency. This is where G80 Lifting Chain stands out. Engineered from high-strength materials, this premium Alloy Steel Lifting Chain is heat-treated to achieve a Grade 80 classification, offering a superior strength-to-weight ratio compared to standard carbon steel chains. Its robust construction makes this Heavy Duty G80 Alloy Steel Lifting Chain a reliable choice for industries such as construction, manufacturing, mining, and shipping. The chain is designed to withstand high-stress conditions, providing the durability and reliability needed for critical overhead lifting tasks, rigging, and load securing.
The G80 Alloy Steel Lifting Chain is manufactured to meet rigorous international standards, including ASME B30.9 and other relevant regional certifications. Each component, from the alloy steel links to the accompanying master links and coupling links, undergoes stringent quality control and proof testing to ensure consistent performance and traceability.
G80 Alloy Steel Lifting Chain Specifications
Below is a detailed breakdown of the key specifications for various chain sizes. All working load limits (WLL) are based on a straight lift and must be de-rated for non-vertical or choker hitch configurations as per safety guidelines.
- Material: High-tensile alloy steel, quenched and tempered.
- Grade: 80 (G80).
- Finish: Self-colored, yellow zinc plated, or hot-dip galvanized for corrosion resistance.
- Standards: Complies with ASME B30.9, DIN 5687-1, ISO 3075, and other international standards.
- Testing: Individually proof tested to 2 times the WLL.
- Temperature Range: Recommended for use between -40°C and 200°C (-40°F to 400°F).
