Heavy duty cart wheels from Xiamen Yirong Hardware Co., Ltd. are the backbone of heavy material handling, designed to withstand extreme loads, rough surfaces, and continuous use in the most demanding environments. These wheels are built with a multi-layered construction: a solid steel or cast iron core provides structural integrity, while the outer tread is made from high-density polyurethane, rubber, or even steel—each material chosen for its ability to support weights ranging from 800 kg to 3,000 kg per wheel. Polyurethane treads offer the best balance of strength and floor protection, resisting wear from concrete floors and metal ramps while cushioning impacts from uneven surfaces, making them suitable for industrial carts moving heavy machinery parts. Steel treads, often used in construction or mining, provide unmatched durability, withstanding punctures from sharp rocks or metal debris and supporting the weight of large concrete blocks or steel beams. These wheels feature reinforced axles and bearings, with seals to prevent dust, dirt, and moisture from entering—critical for maintaining performance in dirty or wet environments like construction sites or waste management facilities. Their mounting hardware is oversized, with thick steel brackets and high-tensile bolts that ensure a secure connection to the cart frame, even under the stress of sudden stops or starts. Whether used in manufacturing, construction, or heavy logistics, heavy duty cart wheels deliver the reliability and strength needed to move the heaviest loads with confidence.
