Proven Excellence for Global Steel Giants

Supplying equipment for world-class metallurgical facilities like POSCO demands uncompromised quality, strict engineering tolerances, and rock-solid delivery timelines.

In April 2026, our long-term Vietnamese partner officially placed an order for custom heavy-duty crane wheel assemblies. These high-performance wheel sets are scheduled for installation and operation in September 2026 at a major POSCO steel plant facility.

This order stands as a testament to mutual trust built over time. Back in 2025, the client’s executive and technical team conducted an on-site audit of the Henan Tuoke manufacturing facility. Impressed by our advanced forging capabilities, precision machining, and customer-first service, the client decisively initiated a partnership that has resulted in multiple successful repeat orders.

Eliminating Steel Mill Downtime: The Engineering Challenge

In steel manufacturing plants, overhead cranes operate continuously under extreme thermal conditions, heavy wheel loads, and aggressive duty cycles. Failure of a single crane wheel can lead to catastrophic operational halts, premature flange wear, and rail gnawing (rail flange biting).

To ensure our crane wheels operate smoothly without unexpected downtime, Henan Tuoke executes multi-layered quality gatekeeping at every manufacturing stage:

1. Precision Dimensional Verification: Guarantees absolute concentricity and precise tread geometry to prevent rail misalignment and rail gnawing.

2. Advanced Hardness Testing: Ensures uniform depth of hardness across the tread and inner flange to resist heavy contact stress and abrasive wear.

3. Mechanical Strength & Load Testing: Verifies that every wheel assembly handles rated overload capacity without plastic deformation.

Technical Specifications: Die-Forged 42CrMo4 Alloy Performance

To meet the rigorous demands of POSCO-level heavy industry projects, Henan Tuoke offers a comprehensive lineup of crane wheel blanks and complete wheel assemblies ranging from D200 to D800 (200 mm to 800 mm diameter).

Key Material & Craftsmanship Advantages:

Die-Forged 42CrMo4 Alloy Steel: We select premium, high-hardenability 42CrMo4 alloy steel forged under closed dies. This refines the internal grain structure, yielding superior impact toughness and fatigue resistance compared to standard cast or rolled steel.

Flaw-Detection Guaranteed Material: All raw steel billets undergo 100% Ultrasonic Testing (UT) prior to machining to guarantee zero internal voids, inclusions, or micro-cracks.

Tailored Heat Treatment: Tread surfaces undergo specialized induction hardening to achieve optimal surface hardness while maintaining a ductile, shock-absorbing core.

Honoring Customer Trust Through Uncompromising Quality

At Henan Tuoke, every purchase order is a pledge of reliability. We understand that behind every order from our Vietnamese partner lies the trust of global industry leaders like POSCO.

Whether you need standalone wheel blanks or fully integrated wheel block assemblies (complete with axles, bearings, and bearing housings), Henan Tuoke provides custom-engineered solutions designed for smooth travel, extended service life, and zero unplanned maintenance.
