Asphalt Finisher Parts

SANY Asphalt Finisher Parts

Sany Asphalt Paver Components is an original equipment manufacturer (OEM) parts system developed by Sany Heavy Industry, leveraging its core technologies in road machinery and global manufacturing capabilities. It provides full lifecycle solutions for high-grade highways, municipal projects, airport runways, and other applications, compatible with the entire SA series of pavers (such as SAP200C-10, SAP90C-10S) and select international brand equipment. Its core competitiveness manifests across three dimensions:

I. Technological Innovation and Product Matrix

• Breakthrough Core Technologies
  The independently developed modular screed features a three-section structure (Patent ZL201310642578.2). Its removable wheel sleeves and protrusion protection sleeves enable multi-purpose use for both asphalt and stabilized base construction, extending service life by 30% compared to traditional steel wheels. The screw distributor features variable-pitch blades (sparse front, dense rear) and a segmented structure. Combined with ultrasonic material level sensors, it reduces aggregate segregation by over 40% and achieves paving smoothness of ±3mm/3m. The hydraulic system, developed in deep collaboration with Rexroth, boasts a response time ≤3ms and seal performance tested leak-free through 1 million cycles.
• Smart Technology Integration Equipped with 3D digital paving systems (e.g., SA series), it achieves ±1mm thickness control precision through BeiDou positioning and laser leveling technology. IoT sensors monitor parameters like oil temperature and auger speed in real time, enabling remote fault diagnosis and preventive maintenance. For instance, remote diagnostics reduced equipment downtime by 40% during the Hunan Changzhou Expressway project.
• Stringent Quality Control and Weather Resistance Critical components like planetary gearboxes employ carburizing and quenching processes, achieving ISO 6 gear precision with load capacity exceeding industry standards by 20%. Chassis parts (e.g., 350mm large-pitch tracks) utilize Hardox 500 wear-resistant steel, delivering over 15,000 hours of service life in rock conditions. All components undergo validation in extreme temperatures from -40°C to 120°C and simulated 30% slope operations, meeting international standards including CE and ISO 9001.
