Heavy-duty caster wheels from Xiamen Yirong Hardware Co., Ltd. are robust mobility components designed to handle extreme weights and harsh conditions, combining exceptional strength with durability. Crafted from materials like forged steel, cast iron, or steel-core polyurethane, these wheels support 1,000-15,000kg, withstanding the weight of heavy machinery, construction materials, or full pallet loads. Steel or cast iron wheels excel in high-temperature or sharp-debris environments (foundries, construction sites), while polyurethane variants offer a balance of strength and floor protection for factories or warehouses. Treads are optimized for rough surfaces (concrete, asphalt) to ensure smooth rolling under heavy loads, with precision bearings reducing friction to minimize effort when moving. These wheels are critical for heavy-duty operations, ensuring heavy loads can be moved safely and efficiently in the most demanding environments.
