20 Ton forged crane hook

Why Forged? 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.

Key Features & Benefits

1. Robust 20 Ton SWL (Safe Working Load): Precisely engineered and rigorously tested to handle loads up to 20 metric tons (20,000 kg) safely and efficiently.

2. Premium Alloy Steel Construction: Manufactured from high-tensile, heat-treated alloy steel (typically conforming to standards like DIN 15401 / 15402, FEM, or ASME B30.10), offering optimal strength-to-weight ratio.

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. Integrated Safety Latch (Standard or Optional): Available with a durable, spring-loaded safety latch (meeting DIN 15400 or equivalent) 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 & Point: Precision-ground load-bearing surfaces minimize wear on slings and wire ropes, extending their service life.

7. Rigorous Quality Control: Every hook undergoes stringent non-destructive testing (NDT) like Magnetic Particle Inspection (MPI) or Dye Penetrant Inspection (DPI) to detect any surface flaws.

8. Proof Load Tested: Each hook is subjected to a proof load test exceeding its SWL (typically 200% of SWL) to guarantee structural integrity under extreme conditions before leaving the factory.

9. Corrosion Resistance: Often supplied with a durable protective finish (e.g., galvanized, painted, or phosphate-coated) to withstand harsh industrial environments.

10. Full Traceability: Manufactured under strict quality management systems (ISO 9001 certified), ensuring material traceability and process control.
