20 噸鍛件起重機吊鉤

為什麼要鍛造? The Core Advantage

Unlike cast hooks, the Weihua 20 Ton hook is crafted through the intense forging process. Heated high-grade alloy steel is subjected to tremendous pressure, realigning the grain structure to follow the hook’s contours. This results in:

• Superior Strength: Exceptional resistance to deformation and shock loading, far exceeding cast alternatives.

• Enhanced Toughness: Greater ability to absorb impact energy without cracking, crucial for dynamic lifting operations.

• Increased Fatigue Life: Withstands repeated high-stress cycles significantly longer, reducing replacement frequency and downtime.

• Eliminated Porosity: Forging creates a dense, homogeneous material free from the voids and inclusions common in casting, maximizing structural integrity.

3. Precision Forging & Machining: State-of-the-art forging ensures material integrity, followed by precision machining for perfect dimensional accuracy and smooth load-bearing surfaces.

4. 集成安全鎖 (標准或可選): Available with a durable, 彈簧式安全閂鎖 (meeting DIN 15400 或同等水平) to securely retain slings and prevent accidental disengagement – a critical safety feature.

5. Optimized Shank Design: Features a robust shank with a machined groove for secure seating of rope sockets or shackles, ensuring stable and centered load application.

6. Smooth Throat & 觀點: Precision-ground load-bearing surfaces minimize wear on slings and wire ropes, extending their service life.

7. 嚴格的質量控制: Every hook undergoes stringent non-destructive testing (無損檢測) like Magnetic Particle Inspection (MPI) or Dye Penetrant Inspection (DPI) to detect any surface flaws.

8. 驗證負載測試: Each hook is subjected to a proof load test exceeding its SWL (通常 200% of SWL) to guarantee structural integrity under extreme conditions before leaving the factory.

9. 耐腐蝕: Often supplied with a durable protective finish (例如。, galvanized, 繪, or phosphate-coated) to withstand harsh industrial environments.

10. Full Traceability: 在嚴格的質量管理體系下製造 (ISO 9001 認證的), ensuring material traceability and process control.
