What is a Swing Drive with Motor?
A swing drive with motor is a complete rotating assembly that enables an excavator’s upper structure (house) to rotate smoothly on the undercarriage. It combines:
- A hydraulic swing motor (power source)
- A planetary gearbox / reduction drive (torque multiplication)
This integrated unit converts hydraulic energy into controlled rotational movement, allowing precise positioning, faster cycle times, and safe operation.
