Rototilt® R4 is our tiltrotator designed for excavators weighing between 10-16 tonnes. The R4 is built to endure the harsh environments and significant stresses it will be exposed to in your daily work. Despite its low weight and compact format, the R4 can handle breakout torques of up to 163 kNm. The worm gear means smoother running with less friction, and the rotation sensor in the end section provides more precise positioning with RPS. In addition, the R4 has a high-pressure seal and smart grease fittings with a stable design with lower radial bearings in bronze.

The Rototilt® R4 also includes Rototilt’s other functions and properties, such as an oil-filled rotor housing cast in a single piece for maximum lubrication, minimal wear and an extremely long service life. You gain access to even more benefits in combination with the QuickChange™ quick coupler system and the SecureLock™ safety solution.
