High Light free forged 0.1t0.1t crane wheel hubheat treated free forged

Heat-Treated Free Forged Crane Wheel Hub for Heavy-Duty Industrial Applications. Our heat-treated free forged crane wheel hubs are engineered for extreme load-bearing performance in demanding industrial and port handling environments. Produced through high-precision open-die forging, these hubs feature superior strength, fatigue resistance, and dimensional stability under continuous heavy-duty operations.

Key Features:

  • Material Options: Available in high-strength alloy steels such as 42CrMo4 and carbon steels like 45#, ensuring durability and shock resistance in harsh working conditions.

  • Forging Process: Free forging (open-die) allows for the creation of large, integrated hub geometries with optimized internal grain flow and minimal material defects.

  • Heat Treatment: Quenching and tempering processes enhance hardness, tensile strength, and wear resistance; normalizing is also available for improved microstructure uniformity.

  • Precision Machining: Capable of rough and semi-finish machining of hub bores, flanges, bolt holes, and bearing interfaces to meet exact tolerance requirements.

  • Dimensional Range: Customizable sizes to fit a wide variety of crane types including gantry cranes, bridge cranes, and container stackers.

  • Inspection & Testing: 100% ultrasonic testing, mechanical property validation (tensile, yield, impact), and dimensional checks ensure consistent quality and performance.

Typical Applications:

  • Port and shipyard gantry crane wheel hubs

  • Bridge crane trolley and drive wheel assemblies

  • Industrial crane wheel systems for material handling, mining, and heavy transport

Our forged crane wheel hubs are designed to withstand repeated high-impact loading, abrasive working conditions, and long-term operation without deformation or failure. We offer full traceability and tailored production to match your specific operational requirements.

Item Details
Product Name Heat-Treated Free Forged Crane Wheel Hub for Heavy-Duty Industrial Applications
Material Grades - High-strength alloy steels: 42CrMo4 - Carbon steels: 45# - Offers outstanding load-bearing capacity, shock absorption, and extended service life under high-impact, heavy-duty conditions
Forging Equipment - Hydraulic hammers: 5T / 8T / 12T - 3600T open-die forging press for large-diameter hub-shaped forgings - Capable of forming integrated hub geometries with flanges, bores, and locking features
Manufacturing Process Hot Forging → Heat Treatment (Normalizing / Quenching + Tempering) → Ultrasonic Testing → Rough / Semi-Finish Machining → Dimensional & Surface Inspection
Forging Ratio ≥ 3.0 — Ensures directional grain flow for enhanced fatigue strength, impact resistance, and wear resistance in rotating crane components
Applications - Wheel hubs for gantry cranes, bridge cranes, and container stackers - Trolley wheels and drive wheel hubs for crane systems - Industrial wheel hubs for material handling, mining, and port logistics
Heat Treatment Options - Quenched + Tempered for superior mechanical performance and surface hardness - Normalizing for improved grain uniformity and dimensional control - Optional stress-relief annealing to minimize residual stress and improve machinability
Testing & Inspection - Chemical: Alloy composition verified by spectrometer - Mechanical: Hardness, tensile strength, yield strength, and impact toughness (axial & transverse) - Ultrasonic Testing (UT): 100% volumetric defect detection - Dimensional: Bore concentricity, flange flatness, roundness, and surface roughness inspection
Value-Added Services - Pre-machining of hub bores, bolt holes, and bearing interfaces -  Complete material traceability: heat number, batch number, and certified inspection records


The steel forgings production flow:

Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
