Installation and Working Principle
Our swing gearbox is typically installed on the back of the upper structure of the excavator, where it is connected to the hydraulic system and the slewing ring. When hydraulic oil is pumped into the gearbox, it drives the internal gears to rotate, which in turn rotates the upper structure.
Here's a detailed image of how our swing gearbox is installed in an excavator:

The key components of our swing gearbox include the motor, gear, bearing, and seal. The motor converts hydraulic pressure into mechanical energy, while the gear system amplifies the torque and reduces the speed. The bearing and seal ensure smooth and leak-free operation of the gearbox.
