VOLVO EXCAVATOR PARTS MADE IN CHINA NEW VOE122745695 BRACKET SPARKLING MACHINERY
SPARKLING MACHINERY NEW VOE122745695 Bracket is a dedicated, heavy-duty structural component exclusively engineered for compatible VOLVO excavator models—versatile equipment widely used in construction, mining, and infrastructure maintenance projects. As a core mounting and support part, it secures critical excavator components (e.g., hydraulic hoses, electrical harnesses, or auxiliary accessories) in place, ensuring stable positioning even during high-intensity operations. This function is vital for preventing component displacement or damage caused by vibration, shock, or heavy loads during tasks like rock breaking, material loading, and deep excavation. It also optimizes the layout of on-board systems, reducing friction between moving parts and minimizing the risk of unplanned downtime.
Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE122745695, the bracket withstands harsh working conditions: extreme temperature fluctuations (-25°C to 105°C), continuous vibration, and exposure to dust, moisture, or construction debris. It maintains structural integrity and resists corrosion, providing long-lasting support for the excavator’s key systems. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for applicable VOLVO excavator models.

MADE IN CHINA SPARKLING MACHINERY NEW XZFK-404 DIGITAL FLOW METER
SPARKLING MACHINERY NEW XZFK-404 Digital Flow Meter is a premium China-made fluid monitoring component designed for compatible construction machinery, hydraulic systems, and industrial fluid circuits—including those in excavators, loaders, and hydraulic power units. As the "fluid measurement guardian" of machinery systems, it accurately detects and displays real-time flow rates of hydraulic oil, coolant, or other industrial fluids, with a measurement range tailored to heavy-duty equipment needs. This enables operators and maintenance teams to monitor fluid circulation efficiency, identify abnormal flow (e.g., leaks, blockages), and optimize system performance—critical for preventing hydraulic component damage, reducing energy waste, and ensuring stable operation in construction, mining, and industrial scenarios.
Engineered to original equipment standards, it maintains high measurement accuracy even under harsh working conditions: high hydraulic pressure (up to 35 MPa), temperature fluctuations (-20°C to 80°C), vibration, and exposure to dust or hydraulic fluid contaminants. With a clear digital display (for easy readability) and a robust, corrosion-resistant housing, it resists environmental wear and ensures long-term reliability. Backed by strict quality verification, it guarantees precise fluid data to support proactive maintenance and minimize downtime caused by fluid system failures.

MADE IN CHINA SPARKLING MACHINERY NEW 14704262 CENTER SWIVEL JOINT
SPARKLING MACHINERY NEW 14704262 Center Swivel Joint is a premium China-made hydraulic connection component designed for compatible excavators. As a critical link between the excavator’s fixed lower structure (undercarriage) and rotating upper structure (cabin, boom, and working arms), it enables uninterrupted 360° rotation while maintaining seamless hydraulic fluid transmission to core systems—including swing motors, hydraulic cylinders, and control valves. This ensures consistent power delivery for essential operations like digging, lifting, and precision swing movements in construction, mining, and earthmoving tasks.
Engineered to original equipment standards, it maintains leak-free performance even under high hydraulic pressure (up to industry-standard thresholds) and continuous rotational stress, as well as harsh working conditions such as dust, vibration, and exposure to construction debris or moisture. With optimized high-wear-resistance sealing rings and precision-machined internal flow channels, it minimizes pressure loss and prevents fluid contamination, protecting the hydraulic system from damage. Backed by strict quality verification, it guarantees reliable operation to support uninterrupted machinery rotation and maximize work efficiency.
