SPARKLING KHR50011 & KHR50017 ECU – Reliable Excavator Control

The KHR-series Electronic Control Units (ECUs) are advanced engine and hydraulic control modules specially designed for CASE CX-series crawler excavators, including CX130DLC, CX250DLC, CX300DLC, and CX490DLC. These ECUs—part numbers KHR50000 to KHR50017—manage core operational functions such as engine response, fuel injection, hydraulic system regulation, and machine diagnostics, ensuring smooth operation, fuel efficiency, and maximum productivity on-site. Engineered for OEM-level compatibility and reliability, each unit is: Pre-programmed and ready for installation

· Function: This is an ergonomic joystick handle used to control secondary machine functions, such as auxiliary hydraulics, attachment movements (e.g., thumb or grapple), and transmission shifting.
· Design: It typically features multiple integrated thumb buttons and/or rocker switches to allow for multi-function operation without the operator releasing the joystick.
· Durability: Built to withstand heavy vibration, dust, and moisture common in construction and mining environments.

   SPARKLING MACHINERY NEW 2290 2390 2391 2491 2590 250-7700 Turbocharger is a core engine performance component for 5 Caterpillar equipment models (heavy-duty construction/mining use). It boosts air intake pressure to enhance combustion efficiency and amplify engine power. 
   Meeting Caterpillar OEM standards (250-7700), it resists up to 820°C high temps, pressure, and wear, ensuring seamless compatibility and long-term reliable engine performance.

   SPARKLING MACHINERY NEW EC140B EC140C EC160B EC160C EC180B EC180C VOE14562193 Switch is a dedicated, high-reliability electrical control component exclusively engineered for VOLVO EC140B/EC140C, EC160B/EC160C, and EC180B/EC180C crawler excavators—versatile mid-sized equipment widely used in construction, municipal engineering, and light mining projects. As a core interface for the excavator’s electrical system, it enables precise activation and control of key functions (e.g., auxiliary lights, hydraulic auxiliary systems, or safety alarms), ensuring responsive operation and operator safety during high-intensity tasks. This function is vital for maintaining smooth workflow coordination, preventing accidental function activation, and avoiding operational disruptions caused by faulty electrical controls during tasks like trench digging, material loading, or site grading.

   Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE14562193, the switch withstands harsh working conditions: extreme temperature fluctuations (-30°C to 70°C), water and dust ingress (IP65 protection rating), and continuous vibration from heavy-duty use. It resists electrical interference and mechanical wear, providing long-lasting control reliability for the six VOLVO crawler excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily excavator tasks.
