In global mining and large-scale earthmoving projects, the CAT 740 articulated dump truck has become an industry benchmark for its exceptional load-bearing capacity and reliability. As a critical component of heavy equipment, wheel rims must maintain strength and stability under high loads, complex terrain, and harsh environments. HYWG, leveraging its leading manufacturing processes and global support experience, provides the CAT 740 with high-performance 25.00-25/3.5 wheel rims, ensuring safe and efficient operation in demanding conditions.
he CAT 740 articulated truck is commonly used in open-pit mines, infrastructure projects and heavy earth and rock transportation. In the harsh conditions of mines and quarries , the fully loaded weight of the vehicle can exceed 70 tons . The overweight load places extremely high demands on the rim bearing capacity.
Complex road conditions such as rugged mountainous terrain, soft soil, and slippery environments can easily cause impact and rim deformation. Coupled with the long-term, high-intensity continuous operation of vehicles , the rims must have excellent fatigue resistance.
HYWG is one of the few companies in China that offers a complete production chain for wheel rims , from steel to finished product . Utilizing independently developed high-strength wheel rim steel , HYWG rigorously controls every production process. From steel rolling and internal and external rim processing to welding and painting, every step ensures wheel rim precision and reliability. This not only ensures product consistency and reliability, but also significantly improves production efficiency and cost control.
The 25.00-25/3.5 rim is designed with a 5PC multi-piece structure. The lock ring cooperates with the bead seat to ensure that the tire is not easily unseated under low pressure, impact or heavy load conditions . It also facilitates the installation and removal of large-size tubeless tires, and is easy to assemble and maintain . It does not require expensive special pressing equipment and has high maintenance efficiency.
The 25.00-25/3.5 rim is a large-size multi-piece OTR rim designed for heavy-duty construction machinery. It features high strength, impact resistance, and easy maintenance. It is a key component for articulated trucks such as the CAT 740.
The factory has passed ISO 9001 and other quality management system certifications and obtained CAT 's certificate recognition. Its excellent quality and stable supply capacity make HYWG the preferred partner of CAT .
