List of spare parts

The swing drive acts as the "load-bearing rotational joint" in the excavator's powertrain, demanding extremely stringent performance:

• Exceptionally High Torque Output: Must generate sufficient torque to overcome the upper structure's massive inertia and the resistance of the working load during starting and rotation.

• Outstanding Reliability: Must guarantee long-term, trouble-free operation under harsh conditions, frequent starts/stops, and exposure to massive impacts and alternating loads. Internal gears and bearings are typically specially heat-treated and precision-machined.

• Smoothness & Precision: Rotation must be smooth and fluid, avoiding jerking; starts and stops must be responsive and positioning accurate – crucial for operator feel and job efficiency.

• High Efficiency: Minimize losses in converting hydraulic energy to mechanical energy, reducing power consumption and heat generation.

• Compactness & Lightweighting: Minimize volume and weight while ensuring strength, optimizing overall machine layout.
