Together with the Lehmatic quickcoupler system, the hydraulic Tiltrotator / Rototilt notably extends the scope of application of a hydraulic excavator with the Tiltrotator acting like a wrist between the excavator and the attachment. An integrated control system allows for continuous rotation and swivelling up to 40° in either direction. Attachments are safely and easily changed, even without leaving the cab in the case of the hydraulic quickcoupler.
