TOPONE® Heavy Lifting Chains: BV-Certified Industrial Safety

  Xintai Taida Mirso Co., LTD manufactures heavy lifting chains depended upon in 30+ countries, now certified by Bureau Veritas (BV) certification. Our 15,000㎡ factory manufactures alloy steel chains for corrosive conditions, G80 lifting chains for 80,000 psi loads, and boat lift chains enduring 1,200+ saltwater hours. The BV audit verified adherence to EN 818-2, ASME B30.9, and DIN 22252 requirements in chain and shackles assemblies and chain rope slings. With 9 automated lines and robotic welding, we prioritize safety over claims of sales.

How BV Certification Makes Heavy Lifting Chains More Reliable

1. Verification of Material Integrity

BV engineers performed the following tests:

·Alloy steel chains (DIN 766): Marine corrosion resistance ratios of chromium and nickel

·G80 lifting chains: Consistency of tensile strength (±2% batch tolerance)

·Boat lift chains: Performance in salt spray testing (exceeding ISO 9227)

2. Validation of Load Capacity

·Chain and shackles: 100% load-tested to Grade 100/120 shackles equivalence

·Chain rope slings: Fatigue resistance at 80% WLL (50,000+ cycles)

·Heavy lifting chains: DNV-approved for ship anchor systems (2,200 N/mm²)

3. Production Process Audits

BV traced:

·Robotic welding precision (0.1mm tolerance) for heavy lifting chains

·Traceability of raw alloy steel to final chain rope slings

·Packaging procedures to safeguard against corrosion during

Why Choose BV-Certified Chains?

·Customs efficiency: 98% clearance rate in BV-recognized countries

·Risk reduction: Full documentation trail for insurance compliance

·Interoperability: Chains are ideally compatible with Crosby/Demag systems
