R4

The Rototilt® R4 is our tiltrotator designed for excavators weighing between 10-16 tonnes. The R4 is built to cope easily with 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. Our latest model has a number of benefits for you as a machine operator or machine contractor. These include a worm gear for smoother running and less friction, as well as a rotation sensor in the end section that provides more precise positioning with RPS. In addition, the R4 has a high-pressure seal and smart grease nipples in combination 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 ICS control system, the QuickChange™ quick coupler system and the SecureLock™ safety solution.
