   SPARKLING MACHINERY NEW EW160C EW160D EW160E EW180C VOE14558958 Disc Brake is a dedicated safety component for VOLVO EW160C/EW160D/EW160E/EW180C wheeled excavators (versatile for road construction, municipal engineering). As the core of the excavator’s braking system, it delivers stable stopping force to ensure safe on-road travel (between job sites) and off-road operation (uneven terrain), preventing accidents during loading or navigation.
   Meeting VOLVO OEM standards (part no. VOE14558958), it endures high friction, -30°C to 90°C temps, and vibration. It resists wear and corrosion, ensuring long-term braking reliability for the four VOLVO models, with strict testing guaranteeing compatibility and safe performance.

   SPARKLING MACHINERY NEW EC200D 14730968 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC200D crawler excavators—versatile mid-sized equipment widely used in construction, municipal engineering, and light mining projects. As a core protective component for the excavator’s hydraulic system, it covers critical areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming reliable leakproof barriers. This function is essential for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, debris, or moisture from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during tasks like trench digging, material loading, and site grading.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 35 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous excavator vibration. It resists oil aging and wear, providing long-lasting protection for the EC200D’s hydraulic system. Backed by strict performance verification, it guarantees uninterrupted sealing support for VOLVO EC200D excavators.

   SPARKLING MACHINERY NEW EC120D EC140C EC140D VOE14557295 Joystick Controller Assy is a premium China-made operational component specifically engineered for EC120D, EC140C, and EC140D excavators. As the core human-machine interface (HMI) of the machinery’s control system, it translates operators’ manual inputs into precise electrical signals to regulate critical excavator functions—such as boom lifting, arm articulation, bucket operation, and upper structure swing. This ensures intuitive, responsive control during construction, landscaping, and light to medium-duty earthmoving tasks.

   Designed to original equipment standards, it maintains consistent sensitivity and smooth operation even under prolonged use and harsh working conditions, including cabin vibration, dust accumulation, and temperature fluctuations. Its ergonomic handle design reduces operator fatigue during long shifts, while the robust outer casing resists wear and impact. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted, precise machinery operation, minimizing errors and enhancing work efficiency.
