Rototilt® R8

The perfect tiltrotator for those heavier job such as earth-moving and road work. Optimised for excavators between 23-32 metric tons.

The updated model has several improvements:

  • New worm gear for even smoother operation and less friction.
  • A rotary sensor in the end section for more accurate positioning together with RPS.
  • New high-pressure seals and smarter nipples
  • Beefier construction with new lower radial bearings in bronze

 

Several benefits

The R8 tiltrotator also provides all of Rototilt's other unique benefits:

  • An oil-filled rotor housing cast in a single piece for maximum lubrication and minimal wear, which means very long service life.
  • Rototilt's control system (ICS) boosts your tiltrotator with smart functions and outstanding user-friendliness, enabling both productivity-enhancing automation (RPS) and market-leading safety (SecureLock™) in one and the same system.
  • Simpler maintenance and longer service life thanks to integrated carrier plates, improved central lubrication (ILS) and a new type of hydraulic coupling.

Right cast goods at the right place ››

A cast rotor housing is both stronger and lighter than welded alternatives. The thickness of the casting is optimised according to the load on the various parts.

‹‹ Smoother operation with new worm gear

The new worm gear boasts improved geometry and stricter wheel and screw manufacturing tolerances, providing smoother operation and reduced friction. The worm gear is also equipped with a new worm screw with integrated lubrication channels, which improves and further extends the service life of the tiltrotators.

Large bearing surfaces effectively absorb and distribute excavation forces.

 

Protected hydraulic motor ››

The specially designed guard for the hydraulic motor is integrated with the cast rotor housing and protects it against impact and shocks from beneath.

‹‹ Smart attachment frame

With a direct attachment frame, you get lower overall costs, lower weight and more digging power. For maximum flexibility, we have developed our own, patented multi-attachment frame.

Powerful cylinder solutions with load management ››

All our cylinders feature load management as standard, which increases workplace safety; the load is secure, even in the event of a hose rupture, for example

Self-lubricating bushings on the cylinder attachments mean fewer lubrication points and consequently simpler maintenance.

Choose between single-action or double-action cylinders. Single-action for as compact a solution as possible and double-action to maximise power. 

‹‹ Excellent safety

All solutions and parts are tested to maximise safety, durability and ease of use. From quality assurance of all component parts, to control systems, couplings and tool locking. With SecureLock™ you can be sure that your tools are correctly attached from the start and that they stay that way.

‹‹ Smart control systems

With Rototilt® you can choose the control system that optimises your excavator and contributes to increased performance, better handling and more options for settings. Choose between ICS, TLE and TE. Your tiltrotator works optimally even in very difficult operating conditions.

More precise positioning with new rotation sensor ››

The sensor in the hydraulic motor has been replaced with a rotation sensor in the housing. The new sensor uses absolute readings with greater precision, providing even better positioning together with Rototilt RPS.

Hydraulic quick coupler ››

Provides faster switching between hydraulically controlled tools. With QuickChange™ we can offer integrated hydraulic quick coupling in the quick coupler.

‹‹ Electric swivel

With an electric swivel (optional), you can control the valves on the tools coupled to your tiltrotator. In this way, even more advanced tools can be used.

Hydraulic high-flow swivel ››

With a high-flow swivel (optional), you can use flow-intensive tools at up to 200 litres/min. and 350 bar.

‹‹ Long service life

Sturdy, amply dimensioned pins, shafts and bushings make your tiltrotator from Rototilt® more robust and long-lasting than any other tiltrotator on the market.

Stability and strength ››

A very strong bolted joint holds the rotor housing and the quick coupler in a firm grip.

‹‹ High performance

Rototilt's tiltrotators work with higher system pressure than other brands on the market. This provides better performance for all functions – such as for important tilt and torque manoeuvres, and more clamping force when using a grapple.
