   SPARKLING MACHINERY NEW R170W7 R170W7A R170W9S ZGAQ-02283 Cylinder-Steering is a premium China-made hydraulic component specifically engineered for R170W7, R170W7A, and R170W9S wheel excavators. As a critical part of the steering system, it converts hydraulic pressure into linear motion to enable smooth and precise directional control, ensuring stable maneuvering during operation, positioning, and job site navigation.

   Designed to original equipment standards, it maintains consistent force output and responsive operation even under heavy loads and continuous use. With optimized seal design for leak resistance and robust structural integrity, it adapts seamlessly to harsh working environments, from muddy construction sites to rough terrain. Backed by strict quality verification, it guarantees reliable performance to support safe and uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 21M9-30102 Cluster Assy is a dedicated instrument panel assembly exclusively designed for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s operator information system, it integrates critical gauges, warning lights, and digital displays to real-time monitor key operational data—including engine speed, oil pressure, coolant temperature, fuel level, and hydraulic system status. This function is essential for operators to make timely adjustments during heavy-duty tasks like digging, loading, and site grading, directly ensuring safe machinery operation, preventing potential component damage, and maintaining consistent work efficiency.

   Engineered to match original equipment performance standards, it maintains clear readability and stable data transmission even under harsh working conditions, including continuous vibration, dust exposure, and temperature fluctuations. It resists electrical malfunctions and display dimming, avoiding information delays or errors that could lead to operational risks or unplanned downtime. Backed by strict performance verification, it guarantees reliable data feedback to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW ZH200-A ZH200LC-A ZX200-5G 9315463=4705920=YA00031829 Switch Box is a dedicated operator control component for Hitachi ZH200-A, ZH200LC-A, and ZX200-5G crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As the "control hub" of the excavator’s cab, it houses key operation switches (e.g., ignition, work mode, auxiliary function) to transmit operator commands to the main controller—ensuring quick, accurate activation of critical functions during digging, loading, and slope trimming.
   Meeting Hitachi OEM standards (cross-referenced part nos. 9315463, 4705920, YA00031829), it endures -30°C to 85°C temperatures, resists dust and vibration, and maintains stable electrical contact. Strict testing guarantees seamless compatibility with the three Hitachi models and long-term reliable cab control.
