High Torque Corrosion Resistant Forged Gear for Port Crane Gear Drives.

 

Our high torque corrosion resistant forged gears are engineered specifically for demanding port crane gear drive applications. Crafted from premium alloy steels and precision forged to enhance grain structure, these gears provide exceptional strength and durability under heavy load conditions.

 

Item Details
Product Name High Torque Corrosion Resistant Forged Gear for Port Crane Gear Drives
Material Grades - Alloy steels selected for excellent corrosion resistance and high torque capacity, suitable for harsh marine and port environments
Forging Equipment - Hydraulic Hammers: 5T, 8T, 12T- Capable of open die forging for medium to large gear blanks Max weight: 7 tons
Manufacturing Process Forging → Heat Treatment → Rough Machining → Gear Hobbing/Shaping → (Optional) Gear Grinding  → Precision Inspection
Forging Ratio ≥ 3.0 — Ensures dense grain structure, enhanced fatigue resistance, and superior load-bearing performance under heavy torque and shock loads
Heat Treatment Options - Normalizing and tempering for enhanced core strength and toughness
Applications - Port cranes including container cranes, gantry cranes, and ship-to-shore cranes- Heavy-duty hoisting and lifting equipment- Offshore and marine cranes
Process Compliance - Fully customized production according to client drawings and operational requirements
Delivery Conditions - Heat treated and supplied as rough-machined or finish-machined gears- Optional hardened gear teeth for improved wear resistance and corrosion protection
Testing & Inspection - Chemical Composition Testing- Mechanical Testing: Strength, Toughness, Hardness- Non-Destructive Testing: Ultrasonic Testing (UT), Magnetic Particle Testing (MT)- Gear Precision Inspection: Profile, Lead, Pitch, and Runout measurement using advanced metrology equipment

Product Features

  • Exceptional Torque Capacity
    Designed to handle the heavy torque loads typical in port crane operations, ensuring reliable power transmission during lifting and hoisting tasks.

  • Corrosion Resistant Materials
    Manufactured from specially selected alloy steels with enhanced corrosion resistance properties to withstand harsh marine and port environments.

  • Precision Forging & Machining
    Produced through advanced forging techniques that improve grain flow and internal structure, followed by precision CNC machining to achieve accurate tooth profiles and smooth gear engagement.

  • Durable Surface Treatment
    Heat treatment processes such as carburizing and induction hardening enhance surface hardness and wear resistance, extending gear service life even under abrasive and corrosive conditions.

  • Robust Design for Shock Loads
    Engineered to absorb sudden impact and shock loads typical in heavy lifting, minimizing gear fatigue and reducing downtime.

  • Customizable Specifications
    Available in various sizes, tooth profiles, and materials tailored to meet specific port crane gearbox requirements.


Application Scenarios

    • Port and Harbor Cranes
      Ideal for main and auxiliary gear drives in container cranes, gantry cranes, and ship-to-shore cranes operating under heavy load and marine exposure.

    • Material Handling Equipment
      Suitable for heavy-duty hoists, stacker-reclaimers, and bulk cargo handling machinery in ports and terminals.

    • Offshore Loading Systems
      Applied in gearboxes for offshore cranes and lifting equipment exposed to saltwater and harsh weather conditions.

    • Heavy Industrial Cranes
      Used in industrial crane gearboxes requiring high torque transmission and corrosion resistance in challenging environments.
