In the heavy‑industry lifting sector, a stable, safe, and highly adaptable lifting point is a critical component for ensuring the efficient transport, installation, and maintenance of equipment. The NOB heavy‑duty flange lifting point, with its superior structural design, stringent material specifications, and versatile compatibility across diverse applications, has become the preferred solution for high‑capacity lifting in industries such as wind power, shipbuilding, heavy machinery, and energy & chemical engineering.
Core Product Advantages: Safety First, Performance Reigns Supreme
1. High‑strength material with a load capacity far exceeding standards: NOB heavy‑duty flange lifting points are precision‑crafted from 42CrMo high‑strength alloy structural steel, undergo integral forging and quenching‑tempering heat treatment (HRC 28–32), and are subjected to nondestructive testing (UT/MT) to ensure the material is free of internal defects such as cracks and porosity. Rated loads range from 85 t to 250 t, with a breaking load exceeding four times the rated capacity (in compliance with EN 1677‑1/ISO 3266 international standards), enabling stable load-bearing even under extreme operating conditions and eliminating the risk of fracture at the source.
2. Flanged Design for Stable Installation and Stress Distribution Unlike conventional lifting points, the NOB employs a large‑size flange integrated into a single unit, rigidly connecting to the lifted equipment via multiple high‑strength bolts. The contact surface achieves a fit of over 98%. This design evenly distributes lifting stresses throughout the equipment body, preventing excessive localized loads that could cause deformation or damage—making it particularly well suited for lifting precision equipment such as large pressure vessels and wind turbine tower sections.
3. Full‑scene compatibility, confidently handling harsh environments Multi‑specification compatibility: Flange diameters range from 100 mm to 600 mm, accommodating M20–M80 threaded holes; custom fabrication is available to meet equipment‑specific flange standards, addressing non‑standard requirements. Superior corrosion resistance: The surface undergoes sandblasting for rust removal followed by hot‑dip galvanizing (zinc coating thickness ≥ 85 μm) or Dacromet treatment, delivering over 1,000 hours of salt‑spray corrosion resistance and ensuring suitability for marine, chemical, and high‑humidity environments. Multi‑angle lifting: Featuring a built-in high‑precision bearing system, it enables 360° rotation and 180° flipping, automatically adjusting the load direction during lifting to prevent wire rope twisting and wear.
4. End-to-end quality control and comprehensive compliance certification: From raw material procurement to finished‑product shipment, NOB implements a rigorous quality management system. Each batch undergoes tensile testing, hardness measurement, and impact‑toughness evaluation; it is certified by CE, CCS (China Classification Society), and ABS (American Bureau of Shipping), meeting the safety standards of the European Union, China, and the International Maritime Organization. We provide complete material certificates, test reports, and user manuals to ensure compliance with industrial project requirements.
Typical application scenario: Wherever there is heavy load, NOB is there.
Wind power industry: hoisting and transportation of wind turbine towers, blades, and nacelles;
Shipbuilding: hull block assembly, large propellers, and deck equipment installation;
Energy and Chemical Engineering: Lifting and positioning of large reactors, storage tanks, and heat exchangers;
Heavy machinery: factory shipment and on-site installation of CNC machine tools, hydraulic presses, rolling mills, and other equipment;
Construction Engineering: steel‑structure bridges, precast concrete components, and self‑erection of large lifting equipment.
