MADE IN CHINA SPARKLING MACHINERY NEW EC200B EC235D EC200D VOE14541069 SWING REDUCER
SPARKLING MACHINERY NEW EC200B EC235D EC200D VOE14541069 Swing Reducer is a dedicated power transmission component exclusively designed for EC200B, EC235D, and EC200D excavators. As the core of the excavator’s swing system, it reduces the high-speed input from the swing motor to generate high torque, enabling smooth, controlled 360° rotation of the upper structure (cabin, boom, and bucket). This function is critical for precise positioning during digging, loading, and material handling tasks in construction, mining, and earthmoving scenarios—ensuring the excavator operates with stability and accuracy even under heavy loads.
Engineered to match original equipment performance standards, it maintains reliable torque output and rotational smoothness even in harsh working conditions, such as intense vibration, dust, and temperature fluctuations. It prevents rotational lag or jitter, safeguards the swing motor from overload damage, and supports continuous operation to minimize workflow interruptions. Backed by strict performance verification, it guarantees long-term operational stability for the excavator’s swing function.
