   SPARKLING MACHINERY NEW E336GC 511-7558 Fan; Cooler is a dedicated thermal management component for Caterpillar E336GC crawler excavators (heavy-duty equipment for mining, large-scale construction, and infrastructure projects). As a core part of the excavator’s cooling system, it works with the radiator to enhance airflow, accelerating heat dissipation from engine coolant and hydraulic oil—ensuring stable operating temperatures during high-intensity tasks like rock breaking, bulk ore loading, and continuous digging.
   Meeting Caterpillar OEM standards (part no. 511-7558), it endures -30°C to 105°C temperatures, resists dust buildup and vibration, and maintains consistent airflow. Strict testing guarantees seamless compatibility and long-term reliable cooling performance for the Caterpillar E336GC.

   SPARKLING MACHINERY NEW 9315463=4705920=YA00031829 Switch Box is a dedicated electrical control component designed for compatible construction machinery, such as excavators and loaders. As a centralized hub for the machinery’s auxiliary electrical functions, it integrates multiple control switches to manage key operations—including lighting systems, windshield wipers, auxiliary hydraulic activation, and safety alarms. This integrated design streamlines the cabin control layout, reduces operational complexity for operators, and ensures quick access to critical functions, which is essential for maintaining efficiency and safety during heavy-duty tasks like construction digging, mining loading, and infrastructure maintenance.

   Engineered to match original equipment performance standards, it maintains stable electrical connectivity even under harsh working conditions, such as cabin vibration, temperature fluctuations, and occasional dust or moisture exposure. It prevents control signal delays or short circuits, avoiding disruptions to auxiliary systems. Backed by strict performance verification, it guarantees long-term reliability to support uninterrupted machinery operation.
