This harness assembly plays a critical role in the machine’s electrical system by securely transmitting signals and power between key components such as sensors, controllers, engine modules, and onboard displays. Designed to withstand the harsh environments of heavy-duty construction operations, it features durable insulation, corrosion-resistant terminals, and OEM-standard connectors for easy installation and long service life.

Whether you are conducting routine maintenance or replacing damaged wiring, this 14532878 wiring harness ensures optimal machine communication and electrical performance. It helps reduce downtime, prevent faults, and support efficient operation on the jobsite.

   SPARKLING MACHINERY NEW EC380E EC480D EC480E 14631200 Travel Reduction Gear is a premium China-made transmission component specifically engineered for EC380E, EC480D, and EC480E excavators. As a critical part of the travel system, it adjusts power output by converting high-speed, low-torque input into low-speed, high-torque motion, enabling steady and powerful movement across diverse job sites, from rough terrain to heavy-load operations.

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

   SPARKLING MACHINERY NEW 8982609301 Turbo is a high-performance engine enhancement component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As a core part of the machinery’s engine system, it compresses incoming air to boost oxygen density in the combustion chamber—significantly improving engine power output, optimizing fuel efficiency, and reducing exhaust emissions during high-intensity operations like heavy digging, load lifting, and continuous idling. This function is critical for maintaining the machinery’s operational efficiency under heavy loads, directly supporting productivity in construction, mining, and infrastructure projects while extending the engine’s service life by ensuring complete, efficient combustion.

   Engineered to match original equipment performance standards, it maintains stable compression efficiency even under harsh working conditions, including extreme engine temperatures (up to 950°C), continuous machinery vibration, and exposure to dust or exhaust contaminants. It resists turbine wear, oil leakage, and bearing failure, avoiding engine power loss or system breakdowns that could lead to unplanned downtime. Backed by strict performance verification, it guarantees reliable power enhancement to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW 363-811-25090 Front Brake Pad Kit is a critical safety component for Tadano excavators (widely used in construction, heavy lifting, and infrastructure projects). As the "front braking backbone", it generates friction with the front brake disc to decelerate or stop the excavator during on-site maneuvering—ensuring responsive braking for tasks like load positioning, slope navigation, and tight-space turning, while preventing front brake failure that risks equipment collisions or on-site accidents.
   Meeting Tadano OEM standards (part no. 363-811-25090), it endures -30°C to 300°C braking temperatures, resists heat fading and wear, and maintains a stable friction coefficient. Strict testing guarantees seamless compatibility with applicable Tadano models and long-term front braking system reliability.
