Description
Heavy-Duty · Precision-Machined · Factory Direct · Global Export
Our crane rail wheels and crane traveling wheels are purpose-engineered for bridge cranes, overhead traveling cranes, gantry crane on wheels assemblies, and port handling equipment. Each wheel is produced from certified alloy steel billets, forged or cast to shape, precision CNC-machined, and subjected to controlled heat treatment for optimal tread hardness and core toughness.
As a direct manufacturer, we eliminate intermediary markups and offer full material traceability — from raw material heat certification through to final dimensional inspection. Whether you require standard catalog wheels, gantry crane wheels, wheeled gantry crane bogie sets, or specialty open groove crane wheels for embedded rail systems, our engineering team supports you from specification to delivery.
We regularly supply MRO replacement wheels, OEM production batches, and bespoke project quantities to buyers across Southeast Asia, the Middle East, Africa, Europe, and the Americas.
Advantages
Manufactured from 55SiMn, 42CrMo, or equivalent alloy steel grades achieving tensile strength typically between 800–1,100 MPa. Raw material mill certificates are provided with every order for full traceability.
Controlled quenching and tempering produces tread surface hardness of HB 300–380 while maintaining a tough, ductile core — reducing spalling, flaking, and premature fatigue cracking under cyclic wheel loads.
Tread diameter, flange profile, and bore concentricity are machined to IT6–IT7 tolerances, ensuring correct rail contact geometry and minimizing vibration in high-speed crane-on-wheels applications.
Standard production wheels cover approximately 5 to 500 tonnes per wheel depending on diameter and material grade. Custom engineering is available for ultra-heavy-lift applications.
Each batch includes dimensional inspection reports and hardness test records. Ultrasonic testing (UT) and magnetic particle testing (MT) available where specified. Third-party inspection by BV, SGS, or TÜV can be arranged.
No distributor layer. Buyers receive transparent factory pricing, shorter lead times, and direct communication with our engineering and production teams — critical for MRO budget and project procurement planning.
Provide a drawing, sample wheel, or dimensional datasheet and our engineers will design to specification. Typical lead time for custom crane wheels: 15–35 working days depending on complexity and quantity.
Regular shipments to 60+ countries. Experienced in export packing, fumigation certification, Certificate of Origin (CO), and complete port-of-departure documentation packages.
Application
Our crane on wheels components are deployed across a broad range of heavy industrial sectors globally. From wheeled gantry crane assemblies in shipyards to replacement traveling wheels in steel melt shops, our products are engineered for continuous duty environments.

Customization Options
| Parameter Category | Parameter Range | Description |
| Wheel diameter (D) | Φ160mm ~ Φ1000mm | Common specifications: Φ250mm, Φ400mm, Φ630mm, Φ800mm |
| Tread width (B) | 80mm ~ 200mm | Must match the rail head width (e.g., QU80 track corresponds to a wheel width of approximately 100mm). |
| Rim height (h) | 20mm ~ 50mm | Double flange (universal), single flange (low lateral force), flangeless (requires guides). |
| Material | Cast steel (ZG340-640), forged steel 42CrMo、65Mn | Cast steel is economical and durable, while alloy steel offers high load-bearing properties. |
| Heat treatment hardness | Wheel surface hardness: HB300~380 or HRC45~55 | Surface hardening improves wear resistance. |
| Single wheel load rating | 5t ~ 500t | Allocation depends on the total crane weight and number of wheels (e.g., a four-wheel crane with a total load of 100t has a single wheel load of approximately 25t). |
| Maximum wheel pressure (P) | 50kN ~ 800kN | Must match the track’s load-bearing capacity (e.g., QU100 track allows for a wheel load of approximately 300kN). |
Why Choose Us?
