Swing Gearbox Fit for Excavator Kobelco SK350-8
High-Quality Swing Gearbox to Meet Your Excavation Needs
A swing gearbox, also known as a swing drive, is an essential component in excavators, enabling the machine to rotate 360 degrees. Our swing gearbox is designed to fit the Kobelco SK350-8 model perfectly. The device is responsible for controlling the excavator's movement and direction, allowing it to move and turn easily, control speed, and assist in the excavation process.
Installation and Functionality
The swing gearbox is installed in the excavator's upper structure, specifically in the platform that connects the cab and boom. It operates by transmitting energy from the hydraulic motor to turn the excavator's upper structure, enabling the cab and boom to rotate 360 degrees, which is necessary for precise excavation work.
