Excavator  EX120-2 Hydraulic EX120-2 Swing Motor 4334356

The EX120-2 is a model of excavator manufactured by Hitachi Construction Machinery. The swing motor in the EX120-2 is a critical component responsible for providing the rotational movement of the excavator's upper structure, allowing it to swing left or right.

Here are some general features and specifications of the swing motor commonly found in excavators like the Hitachi EX120-2:

1. **Type**: The swing motor in the EX120-2 is typically a hydraulic piston motor. This type of motor is commonly used in excavators for its ability to generate high torque and provide precise control over the rotational movement.

2. **Power**: The power output of the swing motor is designed to meet the operational requirements of the excavator. It can vary depending on factors such as the size of the excavator and the demands of the application.

3. **Control**: The swing motor is controlled by the excavator's hydraulic system, which receives signals from the operator's inputs via joysticks or pedals. The control system regulates the flow of hydraulic fluid to the swing motor to adjust the speed and direction of rotation.

4. **Efficiency**: Modern swing motors are designed for high efficiency to ensure optimal performance while minimizing energy consumption. This helps to maximize the excavator's fuel efficiency and reduce operating costs.

5. **Durability**: The swing motor is built to withstand the rigors of excavator operation, including heavy loads, continuous use, and harsh working environments. High-quality materials and robust construction ensure the motor's reliability and longevity.

6. **Maintenance**: Regular maintenance is essential to ensure the longevity and reliability of the swing motor. This may include periodic inspections, lubrication, and replacement of worn parts as needed.
