The SG20E swing drive device serves as a crucial component for the swing system of EC700B, EC750D, and EC900E excavators. Its primary function is to convert the rotational motion and power from the swing motor into the necessary torque and angular movement, enabling the upper structure of the excavator to rotate smoothly and accurately. This allows the excavator to position its working equipment precisely for tasks such as digging, loading, and unloading in various directions.
Gear Ratio
The gear ratio of the SG20E swing drive device is carefully engineered to meet the requirements of the specified excavator models. The specific gear ratio is [X] : 1. This ratio is optimized to balance the speed and torque output, ensuring that the excavator's upper structure can rotate at an appropriate speed while having sufficient torque to overcome the resistance during rotation, especially when carrying heavy loads or operating in challenging conditions. (Note: The actual gear ratio value should be obtained from the product's official documentation and filled in here.)
