   SPARKLING MACHINERY NEW R200W7 R170W7 31N6-10150 31N6-10160 Reduction Gear is a premium China-made transmission component specifically engineered for R200W7 and R170W7 wheel excavators. As a critical part of the power transmission system, it adjusts power output by converting high-speed, low-torque input into low-speed, high-torque motion, enabling efficient operation of key mechanical functions such as swing, travel, or auxiliary movements during construction, material handling, and industrial tasks.

   Designed to original equipment standards, it maintains stable power transfer and optimal torque conversion even under continuous operational stress and heavy loads. With optimized gear meshing design for minimal friction and wear, it adapts seamlessly to harsh working environments, from dusty job sites to rough terrain. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

The Volvo A40F die-cast model is a highly detailed scale replica of the popular Volvo articulated hauler. Manufactured with a full metal alloy body, realistic cabin details, and fully movable components, this 1:35 / 1:50 construction machinery model accurately showcases the design and structure of the real Volvo A40F.

Perfect for showroom display, collector collections, dealer gifts, and engineering machinery demonstrations, the A40F model delivers exceptional durability, precision, and brand authenticity—making it a must-have piece for Volvo construction equipment fans.
