Swing Gearbox Fit for Excavator Komatsu PC360-7
Swing Gearbox Fit for Excavator Komatsu PC360-7
Swing gearbox, also known as swing drive or swing motor, is an essential component of an excavator that is responsible for rotating the excavator's cab and boom. The gearbox consists of a set of gears and bearings that transfer the power from the hydraulic motor to the swing gear. The gearbox is also equipped with a brake system that holds the excavator in place when it is not in use. Some of the specific functions and applications of the swing gearbox include:
- Rotating the excavator cab and boom
- Enabling the excavator to work in a wider range of angles and positions
- Providing stability and safety to the excavator

Installation and Functionality
The swing gearbox is typically installed in the excavator's undercarriage, near the cab. It works by receiving hydraulic fluid from the excavator's engine, which is then used to rotate the gears in the gearbox. This rotation then causes the cab and boom to move in the desired direction. The gearbox is designed to withstand significant stress and pressure, making it an essential component for any excavator. Here's how the swing gearbox works:
- The hydraulic fluid enters the gearbox
- The fluid rotates the hydraulic motor
- The motor transmits power to the gearbox's gears and bearings
- The gears and bearings rotate, causing the cab and boom to move
