Product Advantage
Adopting high-strength alloy steel (such as 42CrMo) for integral forging and undergoing precise heat treatment (quenching and tempering) process, it has both extremely high tensile strength and good toughness, which can withstand heavy loads and effectively resist impact loads, avoiding brittle fracture.
Coarse thread design: Adopting trapezoidal thread (Tr) or ACME thread, its tooth profile is deeper and the tooth base is wider. Compared with ordinary triangular thread, the stress distribution area is greatly increased, fundamentally reducing stress concentration in the thread area and avoiding the risk of "disengagement".
Smooth transition fillet: The connection between the lifting ring and the base adopts a large radius fillet smooth transition, completely eliminating the stress concentration points caused by sharp right angles, which is a key design to prevent fatigue fracture.
By welding and integrating with the base metal, the connection strength depends on the quality of the weld seam, and theoretically it can achieve the same strength as the base metal. This connection method does not have the possibility of loosening or falling off like bolt connections, providing unparalleled connection reliability.
Product Parameters
| Parameter | Specification Range | Notes |
|---|---|---|
| Model Number | e.g., WLE-0.5, WLE-1, WLE-5, WLE-20, WLE-50 | Model numbers correspond to approximate rated load (in tons) |
| Rated Load (Static) | 0.5 t - 50 t | Depending on material and design; static safety factor ≥ 4:1 |
| Rated Load (Dynamic) | 0.3 t - 30 t | Dynamic safety factor ≥ 6:1 for lifting/moving operations |
| Material | High-strength alloy steel (e.g., 16Mn, CrNiMo steel) | Forged and heat-treated for high tensile strength (>800 MPa) |
| Welding Base Size | Diameter: 30 mm - 150 mm; Thickness: 8 mm - 30 mm | Varies with rated load; designed for stable welding to workpieces |
| Eye Inner Diameter | 20 mm - 120 mm | Compatible with common lifting slings, hooks, or shackles |
| Total Height | 80 mm - 350 mm | Distance from welding base to top of the eye |
| Working Temperature | -40°C to +200°C | Suitable for most industrial environments; avoid extreme heat/cold |
| Rotation Range | 360° rotation (some models); 180° flip (optional) | Allows adjustment to load direction, preventing sling twisting |

| Surface Treatment | Powder coating, galvanizing, or black oxide finish | Enhances corrosion resistance for outdoor/harsh environments |
Product Applications
Equipment Assembly: Used in factories producing industrial machinery (e.g., lathes, presses, generators) to lift and position large components during assembly. Welded directly onto machine frames, they enable precise maneuvering of heavy parts.
Maintenance & Repair: In workshops, they facilitate lifting damaged machinery (e.g., engines, pumps) for inspection or repair. Their high load capacity ensures safe handling of bulky equipment.
Steel Structure Installation: Welded onto steel beams, columns, or trusses, they assist in hoisting and aligning structural components during building construction, bridge erection, or stadium development.
Concrete Precast Handling: Attached to precast concrete elements (e.g., wall panels, floor slabs), they enable efficient lifting and placement on construction sites, ensuring stability during transport.
Hull Construction: Welded onto ship hulls, decks, or bulkheads, they support lifting and positioning of large marine components (e.g., propellers, rudders, cargo holds) during vessel assembly.
Offshore Platforms: Used in offshore oil rigs or wind turbine platforms to lift heavy equipment (e.g., drilling tools, generators) during installation or maintenance, withstanding harsh marine environments.
Automotive Production: Integrated into vehicle frames or chassis during manufacturing, they aid in lifting car bodies, truck cabs, or heavy engine blocks along assembly lines.
Aerospace Manufacturing: Welded onto aircraft fuselages, wings, or aerospace components, they enable precise lifting of large parts (e.g., jet engines, structural panels) in production facilities.
Mining Equipment: Attached to mining machinery (e.g., excavators, loaders) or ore containers, they facilitate lifting and moving heavy loads in mining sites, where durability and high load capacity are critical.
Cargo Handling: Welded onto shipping containers, storage tanks, or heavy crates, they assist in loading/unloading operations in ports, warehouses, or logistics centers.
Wind Turbines: Used in wind farm construction to lift turbine towers, nacelles, or rotor blades, withstanding the dynamic loads of outdoor installations.
Solar Panel Arrays: Welded onto support structures for large solar panel systems, aiding in positioning heavy arrays during installation.
Product Operate Guide
Welding installation: Complete welding according to specifications, ensure that the weld seam is firm and free of pores, cool to room temperature after welding, and avoid immediate stress.
