20 吨锻造起重机钩

为什么锻造? 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.
