Heavy-Duty Polyurethane Wheels for AGVs Carrying Over 2 Tons

The heart of the AGV's locomotion system is the heavy-duty polyurethane (PU) wheel, which is the core equipment connecting production and circulation.

Core Feature: Performance Breakthrough in Heavy-Load Scenarios

Ultra-High Load Capacity and Structural Stability: The core advantage of the heavy-duty AGV PU wheel lies in its static load capacity of 3-5 tons per single wheel, maintaining structural integrity even under dynamic impact without deformation.

It utilizes a composite structure of a metal core (steel or aluminum) and a high-hardness polyurethane layer, tightly bonded through hot pressing or injection molding. This design leverages the rigidity of the metal core for the load-bearing foundation and relies on the toughness of the PU material to disperse pressure. Even when handling extreme scenarios like 30-ton container transport, the wheels can achieve stable support through multi-wheel coordination.

Dual Advantages in Wear Resistance and Environmental Adaptability: The wear resistance of polyurethane is 3-5 times that of ordinary rubber, and in extreme conditions, it can even be 5-8 times that of NBR (Nitrile Butadiene Rubber). In high-frequency handling scenarios, the wear rate is only $0.01-0.10, extending the service life by 3-5 times compared to traditional rubber wheels.

Furthermore, it possesses excellent resistance to chemical corrosion, strongly resisting common industrial substances like grease, weak acids, and weak alkalis, with a volume swelling rate of no more than 5%. This allows it to adapt to complex media environments such as chemical plants and food processing facilities. In terms of temperature adaptability, formula modification allows for a wide operating range of $-40, preventing embrittlement in low temperatures and softening in high-temperature conditions, making it perfectly suited for extreme operations like cold chain storage and steel metallurgy.

Silent Operation, Energy Saving, and Floor Protection: Operating noise and floor damage from heavy-duty equipment are common pain points in industrial settings, which the heavy-duty AGV PU wheel addresses through both material elasticity and structural optimization.

Its rolling noise is significantly lower than metal or hard plastic wheels, controlling noise levels to below $65 even when fully loaded. This meets the stringent noise requirements of environments like medical facilities and electronics manufacturing.

Simultaneously, the moderate elastic modulus of polyurethane allows it to absorb impacts from uneven floors, protecting the AGV's internal precision sensors, while avoiding scratches or indentations on epoxy or steel floors, reducing maintenance costs. Its low rolling resistance characteristic further reduces AGV energy consumption by 10%-15% and extends battery life by 20%, providing assurance for long-duration, heavy-load operations.

Typical Applications: Empowering Heavy-Duty Automation Across All Industries

Manufacturing and Automotive Industries:: In automotive assembly workshops, AGVs frequently handle heavy components exceeding 2 tons, such as engine assemblies and chassis frames. After switching to PU wheels with a hardness of $95, equipment failure rates decreased by 40%, and annual maintenance costs were reduced by $200.000$ RMB (approximately $28.000$ USD). In the field of mechanical processing, heavy-duty AGVs utilize these wheels for the precise transfer of machine tools and heavy fixtures, ensuring continuity in process flow by preventing slippage even on oily floors due to a high coefficient of friction.

Port and Logistics Warehousing:: Container handling in ports is one of the core applications for heavy-duty PU wheels. AGVs responsible for transferring 20-foot containers (total weight 30 tons) that adopt $95 hardness PU wheels have an extended service life of up to 2 years, and maintenance costs are reduced by 40%. In automated storage and retrieval systems (AS/RS), the wheels support the lifting of heavy racks and goods transfer. Coupled with narrow-aisle steering design, they increase warehouse space utilization by 50% and improve sorting efficiency by 30%, perfectly adapting to heavy-load goods-to-person sorting requirements.

The heavy-duty AGV PU wheel, with its triple breakthrough in load capacity, wear resistance, and environmental adaptability, has become the core support component for heavy-duty automated handling. From automotive manufacturing to port logistics, and from extreme environments to clean workshops, it not only solves the pain points of poor stability, frequent maintenance, and high wear associated with traditional heavy handling but also adapts to the specialized needs of different industries through its customization capabilities.
