What’s the Zoomlion QUY80 Crawler Crane Bottom Roller?

The primary function of the Zoomlion QUY80 crawler crane bottom roller is to bear the entire weight of the crane, distribute it evenly across the track chain, and ensure smooth travel over rugged terrain. The QUY80’s rollers are engineered for superior load distribution and minimal ground pressure, which is critical for sensitive work environments. This design directly translates into enhanced jobsite versatility and safety, allowing the crane to operate confidently on various surfaces, from soft soil to prepared foundations, without excessive sinking or instability.

Advantages

1）40Mn2 Zoomlion QUY80 crawler crane bottom roller Body & 42Cr Pin

The pin is made from high-strength 42Cr alloy steel, a significant upgrade over the standard 45# carbon steel used in many other models. This provides greater shear strength and resistance to bending under extreme loads.

Benefit: “Resists deformation under load, maintaining alignment and track tension for smoother travel and reduced wear on other undercarriage parts.”

2）100% Copper Bushing

The bushing is constructed from 100% copper, offering far superior lubrication and heat dissipation compared to cost-cutting duplex metal (iron-copper) bushings. With a substantial thickness of 6-10 mm, it is built to last.

Benefit: “Reduces friction and operating temperature, significantly extending the lubrication interval and the service life of the pin and Zoomlion QUY80 crawler crane bottom roller.”

3）Precision-matched Seals

Precision engineering is critical for sealing. Our floating seals are precisely matched to the exact dimensions of the Zoomlion QUY80 crawler crane bottom roller body. This eliminates a common failure point—improperly sized seals that lead to oil leakage, contamination, and rapid bearing failure.

Benefit: “Guarantees a sealed, contaminant-free environment for the bearing, which is the single most critical factor in preventing premature undercarriage failure.”
