Large Section Open Die Casting Forge Heavy Lifting Equipment Hot Forging Process

Large Section Open Die Forgings for Port Crane and Heavy Lifting Equipment. Our large section open die forgings are engineered for demanding lifting and structural applications in port handling systems, gantry cranes, offshore hoisting units, and other heavy-duty lifting equipment. Manufactured from high-strength carbon or alloy steels, these forged components offer exceptional mechanical stability, fatigue resistance, and dimensional reliability under fluctuating and high-load conditions.

Key Features:

• High Load Capacity: Large cross-sectional forging ensures excellent performance under tensile, compressive, and bending loads.

• Enhanced Fatigue Strength: Directional grain flow improves durability under repetitive stress cycles common in lifting operations.

• Superior Machinability: Heat treatment options such as normalizing and tempering provide a balance of strength and machinability.

• Dimensional Precision: Post-forging machining and metrological inspection ensure tight tolerances for complex assemblies.

• Customized Design: Shapes and sizes tailored to specific structural and dynamic requirements of cranes and hoisting equipment.

Typical Applications:

• • Main shafts and spindle forgings for gantry and tower cranes

  • Yokes, couplings, and bearing housings in hoisting systems

  • Load-bearing frames, support arms, and lifting brackets in port and offshore cranes

  • Structural reinforcements in heavy material handling machinery

Frequently Asked Questions (FAQs)

1. What is the typical weight span of the forged components you produce? Our forging capabilities encompass parts weighing from 100 kilograms up to 7 metric tons.
