BelAZ 79770 motor grader on display at the International Mining Exhibition in Novokuznetsk, Russia .
The BELAZ-79770 , a super-large tonnage mining equipment , has become a representative model for high-intensity operations in open-pit mines around the world with its excellent performance and stable performance. The new 70-ton product is equipped with a 600-horsepower diesel engine and a grader shovel made of high-strength steel, with a blade width of 7.3 meters and a maximum shovel depth of 455 mm. Such a super-large mine grader has extremely high requirements for the strength, structural stability and fatigue resistance of the rim . The 25.00-29/3.5 rim we provide is the core support that can ensure that this key equipment can continue to operate efficiently in extremely harsh mining environments .
The mining environment is extremely harsh. Crushed stones, sharp slag, mud and high-intensity work are a huge test for every component of the vehicle. For a heavy-duty grader like BELAZ-79770, the pressure and impact force on the wheel rim are unimaginable.
The vehicle body weighs nearly 70 tons, plus the huge thrust on the ground during operation. The mine road is rugged and uneven, and the vehicle is frequently impacted during driving and operation. The equipped rims must have super load-bearing capacity to support the entire body and operating load. To avoid deformation and breakage, our rims are made of high-strength steel, and through a special heat treatment process, they are ensured to have the characteristics of impact resistance, corrosion resistance, and high temperature resistance. They can be used stably for a long time in extremely harsh environments, reduce maintenance times, reduce maintenance costs, and extend service life.
The new 70-ton grader 79770 launched by BelAZ uses the rims provided by HYWG.
The cooperation between HYWG and BelAZ marks an important milestone for both companies. BelAZ's decision to choose HYWG highlights the latter's expertise and reputation in manufacturing high-quality and durable rims for heavy machinery. With an impressive operating weight of 70 tons, the 79770-class motor grader will greatly benefit from HYWG's precision-engineered rims, ensuring optimal stability, load-bearing capacity and long service life in the most challenging environments.
In heavy machinery like the Belaz 79770, rims are a critical safety and performance component. They carry the tremendous weight of the machine and its load, absorb shock from uneven terrain, and transfer power from the engine to the ground. Substandard rims can cause premature wear, structural damage, and pose a significant safety hazard. Partnering with HYWG ensures that the Belaz 79770 is equipped with best-in-class rims, ensuring it will operate reliably and safely throughout its service life.
HYWG's collaboration with Belaz on the 70-ton class motor grader 79770 underscores the two companies' shared commitment to providing high-performance, reliable heavy machinery. With the Belaz 79770 entering the market, its operators can have confidence in the strength and durability provided by HYWG's carefully crafted rims.
HYWG—a leader in heavy-duty rim manufacturing, is a global leader in the design and production of rims for off-highway vehicles, including mining trucks, loaders and motor graders. With 20 years of experience, HYWG uses cutting-edge technology and strict quality control measures to produce rims that can withstand extreme pressures, heavy loads and harsh conditions. Their commitment to innovation and product excellence was a perfect match for Belaz's requirements for their new 79770 motor grader.
HYWG has rich experience in wheel manufacturing and is the original rim supplier in China for well-known brands such as Volvo, Caterpillar, Liebherr, and John Deere.
