In mines and construction sites, OTR wheels not only bear loads of tens or even hundreds of tons, but also significantly impact equipment stability and operational safety. As a leading global manufacturer of construction machinery rims, HYWG not only produces world-class high-strength OTR rims, but also ensures that every rim achieves optimal performance during installation using rigorous professional standards.
At HYWG, every OTR wheel installation begins with rigorous preparation , and every step from preparation to execution is precise and orderly . A safe zone is established around the equipment , standardized professional lifting equipment is used , all tools are calibrated , and the entire process is operated by technically certified installers . This standardized process ensures that the installation is professional, efficient, and safe from the very beginning.
As a leading global OTR rim manufacturer, HYWG understands the importance of every detail. Before installation, technicians conduct a comprehensive inspection of the wheelset: the rims are free of cracks, deformation, and corrosion ; the rim locks and retainer grooves are intact and unworn ; the tire bead is undamaged and perfectly matches the specifications ; and the rim surface is smooth and meets factory standards .
HYWG is one of the few companies in China capable of producing wheel rims across the entire supply chain , from steel to finished product . The company possesses its own steel rolling, ring component manufacturing, and welding and painting production lines, ensuring product consistency and reliability while significantly improving production efficiency and cost control. The wheel rims utilize globally leading steel profile technology and welding processes, boasting core advantages such as high strength, high toughness, and long service life, making installation smoother and safer.
Clean the tire seat and bead grooves before installation and use a high-grade special lubricant to avoid damaging the tire bead during tire assembly.
Using a specialized crane , the tires are assembled onto the rim base, strictly following the correct assembly sequence corresponding to different rim structures (1-piece, 3-piece, and 5-piece).
HYWG technicians will ensure that the locking ring is fully engaged in the slot without any lifting or misalignment, which is the most critical safety step in multi-piece rims.
After assembly, remove the valve stem, place it inside the safety net for inflation, and after confirming that the assembly is correct, reinstall the valve stem and place the tire rim inside the safety net again for inflation to the specified pressure.
HYWG will perform a final check on the wheelset: whether the tires are evenly positioned , whether the rims are correctly installed , whether the tire pressure is up to standard , and whether the bolts are at the recommended torque .
HYWG's stringent installation standards bring numerous benefits: reduced risk of tire blowouts and rim slippage, extended tire and rim lifespan, improved equipment operational stability, reduced maintenance costs and downtime, and increased mining efficiency. These principles ensure that HYWG rims maintain extremely high safety and reliability in mining environments worldwide.
