The CAT 16G, a classic large grader from Caterpillar, has long been used in open-pit mines, quarries, large-scale earthmoving projects, and highway construction projects. Its main tasks include mine transport road repair, roadbed leveling, slope construction, and large-scale site grading operations.
In practical work, CAT 16G often faces the following challenges:
• Long-term continuous operation results in high equipment utilization;
• The mine roads are rugged and uneven, and the wheel rims are subjected to strong impact loads continuously;
- angle turns and frequent maneuvers generate significant lateral stress;
High temperature, dusty and humid environments place higher demands on the durability of wheel rims;
• The stability requirements for the wheel system are extremely high under heavy-load construction conditions.
To meet these demanding operating conditions, HYWG has specially designed 19.50-25/2.5 5PC high-strength engineering machinery rims for CAT 16G, ensuring efficient equipment operation with superior structural strength and reliability.
19.50-25/2.5 is a 5PC structure rim for TL tires, commonly used on graders. HYWG is an original equipment manufacturer (OEM) rim supplier in China for Volvo, Caterpillar, Liebherr, John Deere, and Doosan.
the harsh working conditions of CAT 16G , HYWG 's R&D team offers 19.50-25/2.5 rims with a mature five-piece structure design, which takes into account load-bearing capacity, ease of maintenance and long-term reliability.
19.50-25/2.5 — Excellent load-bearing and impact resistance
CAT 16G wheels frequently need to traverse potholes, gravel, and uneven road surfaces during mine road maintenance. HYWG rims are manufactured using high-strength rim- specific steel produced in-house , effectively absorbing impact loads and reducing the risk of rim deformation.
Excellent lateral stability performance
When a grader is working, the blade continuously generates lateral resistance, placing extremely high demands on the wheel rim's resistance to lateral deformation. HYWG has optimized the wheel rim structure design to ensure the wheel system remains stable under heavy-load steering and complex working conditions.
Extend tire life
High-precision machining and automated welding production ensure a perfect match between the tire and the rim, effectively reducing abnormal tire wear, improving tire utilization, and lowering customer operating costs.
Easy to maintain on site
19.50-25/2.5 The five-piece structure design allows for easy tire removal, installation, and maintenance, making it particularly suitable for working environments with limited equipment maintenance conditions, such as mines.
HYWG's full-industry chain manufacturing capabilities empower product quality.
HYWG is one of the few companies in the world with the capability to manufacture the entire wheel rim industry chain, enabling it to achieve independent control over the entire process from raw materials to finished products.
Unlike most companies in the industry that rely on purchasing steel from external suppliers, HYWG has the capability to produce its own steel profiles . This advantage means that it can determine the safety limits, consistency, and long-term reliability of wheel rims from the source.
The safety and lifespan of OTR rims are determined from the source of materials. This ensures that the product surpasses ordinary standard rims in concentricity, fatigue resistance, weld strength, and service life. High-strength, high-quality steel guarantees excellent fatigue and impact resistance.
For heavy-duty equipment like the CAT 16G, the quality of materials directly determines the service life and safety performance of the wheel rim.
The HYWG factory is also equipped with a complete industrial chain production from steel to finished wheel rims. From steel rolling, mold design, high-precision forming, automated welding to surface treatment and finished product inspection, this "one-stop" production model can ensure that every process undergoes strict quality control , ensuring that all products meet the same high standards and truly realize the whole chain manufacturing and quality control of wheel rims.
