The H-Lift DIN 766 Short Link Chain is a German-standard, general-purpose welded chain renowned for its consistent link dimensions and optimized strength in demanding applications.
Manufactured to DIN 766 specifications, ensuring precise tolerances required for smooth operation in windlasses and mechanical handling systems.
Short link design provides excellent compactness and durability, making it highly popular for anchor lines, mooring, and barrier installations.
Available in a comprehensive range of sizes from 4mm to 20mm to accommodate Working Load Limits (WLL) from 2.0 kN up to 50.0 kN.
Strictly designed for industrial, marine, and general engineering utility; it is not rated or approved for overhead lifting.
The DIN 766 Short Link Chain is a highly versatile, heavy-duty commercial chain forged from durable Grade 3 carbon steel. Known for its compact short-link geometry, it provides excellent strength and flexibility while resisting tangling. It is the ideal solution for marine anchor lines, vessel mooring, industrial barriers, and general lashing applications.
⚠️ SAFETY WARNING: NOT FOR OVERHEAD LIFTING. This chain is designed strictly for pulling, securing, and mooring. It is a commercial-grade low-carbon chain and is NOT rated for overhead lifting, cranes, or the suspension of loads under any circumstances.
✅ Standard Compliance
Manufactured to adhere strictly to the German DIN 766 standard, which specifies precise dimensions and mechanical properties for round steel link chains (Grade 3).
🛡️ Material & Finishes
Forged from durable carbon steel. Available in a wide variety of surface treatments for tailored corrosion protection, including self-color, electro-galvanized, hot-dip galvanized, blackened, and plastic-coated.
🔗 Compact Short Link Design
The short link geometry provides a compact profile that moves smoothly over sprockets and windlasses. It offers excellent flexibility and is much less prone to knotting or tangling than long-link alternatives.
🛠️ Heavy-Duty Applications
Designed for demanding commercial environments. It serves as an ideal solution for robust marine anchor lines, vessel mooring setups, rugged industrial barriers, and general heavy-duty lashing.

• Marine Grade Upgrade: For superior, long-lasting rust resistance in severe saltwater environments, we highly recommend our Stainless Steel DIN 766 Chain. • Overhead Lifting: For overhead lifting applications and hoists, you must upgrade to our certifiedGrade 80 Alloy Chain. • Hardware: Connect your anchor chain securely with our compatible Hot Dip Galvanized Bow Shackles.
Q: What is the main use for DIN 766 chain?A: DIN 766 is a highly versatile short link chain widely used for marine anchoring, industrial barriers, and general lashing where a strong, compact link is required that resists tangling.
Q: Can I use DIN 766 chain for overhead lifting?A: No. It is typically manufactured from Grade 3 carbon steel, which does not have the elastic ductility required to safely absorb the dynamic shock loads of a crane lift. For any overhead lifting operations, you must strictly use certified Grade 80 or Grade 100 alloy chain.
Chain Grade Guide
What is the Difference Between Welded Chain Grades?
🚫 Carbon Steel ChainGrades 30, 43, 70 Used for tie-downs, towing, and securement. NEVER used for overhead lifting.
✅ Alloy Steel ChainGrades 80, 100 Specifically designed and heat-treated for Overhead Lifting and Sling Assemblies.
How is "Grade" Calculated?
The grade number represents the chain's tensile strength (mean stress value). It is calculated by dividing the tensile force (Newtons) by the cross-sectional area of the two links ($mm^2$).
As the Grade Increases:
The material becomes harder and more resistant to abrasion.
The Strength-to-Weight ratio increases (more lifting power, less weight).
The Working Load Limit (WLL) increases significantly.
Towing, general utility, load securement. Stronger than G30.
NO
Grade 70 (Transport)
Heat-Treated Carbon
Heavy Duty Securement. Standard for trucking tie-downs. Identified by Gold/Yellow finish.
NO
Grade 80 (Alloy)
Alloy Steel
Standard Lifting Slings. High ductility (stretch) to absorb shock.
YES
Grade 100 (Premium)
Alloy Steel
Heavy Lifting. 25% stronger than G80. Harder surface for abrasion resistance.
YES
Common Problems & Critical Safety Warnings
Even with the correct grade, misuse can lead to catastrophic failure. Ensure your riggers are trained to avoid these three common hazards:
⚠️ 1. The Hoist Chain Trap
A frequent and dangerous mistake is using the load chain inside a hoist to wrap around a load.
The Design: Hoist load chain is hardened specifically to fit internal sprockets (tight tolerances). It lacks the ductility (stretch) required for a sling.
The Risk: Wrapping it around a load deforms the links. When retracted, the deformed links can snap or destroy the internal hoist mechanism.
⚠️ 2. The "Gold Chain" Error
Using Grade 70 (Gold) chain for overhead lifting is a common error because the chain looks robust.
Why it Fails: Grade 70 is heat-treated for abrasion resistance (for rubbing against truck beds), not for the elongation needed to absorb the dynamic shock of a crane lift. It may snap suddenly without warning.
⚠️ 3. General Neglect
Alloy chain is tough, but not invincible. Proper storage and inspection are vital.
Corrosion: Leaving chain on damp shop floors promotes pitting and stress corrosion cracking.
Inspection: Chains must be inspected regularly for nicks, gouges, and elongation (stretching).
