Customized 42CrMo Forged Blank for Ship-to-Shore Crane
Wheels,Trolleys.This customized 42CrMo forged blank is specially
engineered for ship-to-shore (STS) crane wheels and trolley systems
operating in high-load port environments.
Manufactured through precision open die forging and optimized heat
treatment, the block provides outstanding tensile strength, fatigue
resistance, and impact toughness. The refined grain structure
ensures long service life and stability under dynamic, repetitive
stresses, making it ideal for critical wheel hubs and rotating
assemblies in heavy-duty port machinery. | Item | Details |

| Product Name | Customized 42CrMo Forged Blank for Ship-to-Shore Crane Wheels,
Trolleys | | Material Grade | - High-performance alloy steel: 42CrMo (AISI 4140 equivalent)-
Exceptional balance of strength, impact resistance, and surface
hardness- Tailored for frequent start-stop, directional reversal,
and heavy brake load environments | | Forging Equipment | - Hydraulic Open Die Hammers: 5T, 8T, 12T- Optimized for
medium-to-large forged rings and wheel blanks used in STS trolley
running systems | | Manufacturing Process | Billet Inspection → Open Die Forging → Normalizing or Quenching +
Tempering → Rough or Precision Machining → Ultrasonic &
Dimensional Inspection | | Forging Ratio | ≥ 3.0 – Ensures directional fiber alignment, improved stress
distribution, and high durability under dynamic crane loading
cycles | | Applications | Specifically engineered for:- Ship-to-shore crane trolley wheels
and drive wheel hubs- Rail-mounted gantry crane rollers and guide
wheel blanks- Suitable for high-duty port operations, including
automated container terminals and shipyard gantry systems | | Heat Treatment Options | - Quenched + Tempered (Q+T): For maximum strength and wear resistance in final-machined
components- Normalized + Tempered (N+T): For semi-finished parts with machining allowance | | Testing & Inspection | - Chemical Analysis: Spectrometer-certified- Mechanical Tests: Tensile, impact, and hardness- Ultrasonic Testing (UT): Internal integrity validation- Dimensional Control: Gauge-based verification of outer/inner diameters, concentricity,
and roundness- Metallography: Grain refinement and heat treatment quality check | | Value-Added Services | - Machined profiles for bores, flanges, and keyways available per
drawing- Anti-corrosion packaging and export-ready crate solutions-
Support for DDP or CIF delivery to port and shipyard locations
