The rippa R325 excavator is operated by the pilot handle, which saves labor and is more stable during work, and has higher efficiency. Changchai, Yanmar and Kubota engines can be selected for assembly. The hydraulic cylinder adopts Japanese NOK sealing parts to prevent oil leakage; the piston rod is made of one-time forging without welding; it is not easy to break. The American Eaton motor we use, with nitriding technology, has a sealing ring inside and a rotary overflow speed control valve to prevent oil accumulation and increase the service life of the motor.
