Heavy duty wheels for carts from Xiamen Yirong Hardware Co., Ltd. are engineered to handle extreme weights and harsh conditions, making them essential for industrial, construction, and logistics applications where standard wheels would fail. These wheels are constructed with a focus on strength: their hubs are made from thick steel or cast iron, providing a rigid core that resists deformation under pressure, while the treads are crafted from high-performance materials like reinforced polyurethane, steel, or rubber compounded for maximum load capacity. Polyurethane treads, for example, can support up to 1,500 kg per wheel, with a hardness of 90 Shore A to withstand compression and abrasion, making them ideal for carts transporting heavy machinery or palletized goods. Steel wheels, often coated with rubber or polyurethane for grip, offer even higher load capacity (up to 2,500 kg per wheel) and excel in construction settings where carts are exposed to sharp debris like nails or rebar. These wheels feature oversized bearings, typically roller or tapered bearings, that distribute weight evenly and reduce friction, ensuring smooth rotation even under maximum load. Their mounting brackets are reinforced with gussets or extra welds, preventing bending or breaking when carts are pushed over curbs or rough terrain. Whether used in factories moving large equipment, construction sites transporting building materials, or warehouses handling full pallets, heavy duty wheels for carts provide the strength and durability needed to keep operations moving efficiently.
