R8

The Rototilt® R8 is the perfect tiltrotator for heavier tasks, such as earth-moving and road work, as it can handle breakout torques of up to 330 kNm and is optimized for excavators weighing between 23-32 tonnes. 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 R8 has a high-pressure seal and smart grease nipples in combination with a stable design with lower radial bearings in bronze. The R8 tiltrotator also provides you with all of Rototilt’s other smart 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 even more benefits in combination with the ICS control system, the QuickChange™ quick coupler system and the SecureLock™ safety solution.
