In industrial transportation and automation equipment, cast iron wheels with polyurethane coating offer a perfect combination of strength and wear resistance, making them an ideal choice for load-bearing and moving applications. They combine the high-strength craftsmanship of a cast iron core with the superior performance of a polyurethane coating, meeting diverse needs from light logistics to ultra-heavy transport.
Cast iron core processing and characteristics
The iron core is typically made of high-strength cast iron or ductile iron, precision machined and heat-treated to ensure the wheel core has the following characteristics:
• High load capacity: High compressive strength and resistance to deformation, suitable for heavy loads and continuous operation;
• Stable structure: High machining precision ensures stable wheel operation at high speeds.
• Impact resistance: Reliable performance under heavy loads and complex road conditions.
Professional advantages of polyurethane coating
The polyurethane material coating the outer layer of the core has the following properties:
• Moderate hardness and resilience: It can withstand high loads while providing a certain degree of cushioning and reducing equipment vibration.
• Wear and corrosion resistance: It maintains a long service life even in high-friction, humid, and chemical environments.
• Surface-friendly: It reduces operating noise and avoids damage to the track or ground.
• Hydrolysis resistance: It is particularly suitable for outdoor operation, high humidity, or chemical media.
Load capacity and application scenarios
Depending on size and process, iron-core polyurethane-coated wheels can be categorized into the following load ranges:
• Light-load (≤500kg/wheel): Suitable for warehouse trolleys, small automated guided vehicle (AGV) transporters, and logistics sorting equipment;
• Medium-load (500kg–2t/wheel): Commonly used in forklifts, high-bay warehouse stacker cranes, and four-way shuttles;
• Heavy-load (2t–10t/wheel): Suitable for heavy-duty automated guided vehicles (AGVs), material transfer platforms, and gantry crane auxiliary wheels;
• Extra-heavy-load (10t–50t/wheel): Widely used in port gantry cranes, large shipyard flatbed trucks, and wind turbine tower transport equipment.
Iron-core polyurethane-coated wheels, thanks to the strength of their cast iron core and the wear resistance and cushioning properties of their polyurethane coating, not only offer excellent load capacity and long life, but are also adaptable to various complex environments. They are essential components in modern industrial equipment.
