   SPARKLING MACHINERY NEW R1200-9 R140LC9 R140W9 R145CR9 R160LC9 R170W9 72Q6-02120 Door Lock Assy is a dedicated cab safety component for Hyundai R1200-9, R140LC9, R140W9, R145CR9, R160LC9, and R170W9 excavators (widely used in construction, mining, and municipal engineering). As the "cab security core", it secures the excavator cab door—preventing unauthorized access, blocking dust/debris from entering the cab, and ensuring operator safety during high-intensity tasks like digging, lifting, and rock breaking, while withstanding vibration and harsh on-site conditions.
   Meeting Hyundai OEM standards (part no. 72Q6-02120), it endures -30°C to 85°C temperatures, resists corrosion and impact, and maintains stable locking performance. Strict testing guarantees seamless compatibility with the six Hyundai models and long-term cab security.

   SPARKLING MACHINERY NEW R290LC7A RD340LC-7 39Q8-42100 39Q8-42102 Travel Reduction Gear is a premium China-made transmission component specifically engineered for R290LC7A and RD340LC-7 excavators. As a critical part of the travel system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling steady and powerful movement across diverse job sites, from rough terrain to heavy-load operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous operational stress and uneven ground conditions. With optimized gear meshing design for minimal wear and energy loss, it adapts seamlessly to harsh working environments, from construction zones to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
