In collaboration with the engineers of New Holland, the RDS/portal has been adapted and type approved in 2 line technology especially for harvesters. The newly developed RDS/portal is the perfect system for comfortably adjusting air pressure on your harvester while in motion. The air lines are led through the axle tube and the axle to the tyre. Lines led outside the vehicle and around the wheel are no longer necessary.
With the RDS/portal, the rotary joints are completely protected from external influences because they are fully integrated into the axle housing of the machine and work completely maintenance free. A special lifetime grease filling at the gasket seals removes the need for grease nipples and makes tedious, time consuming maintenance intervals a thing of the past.
Thanks to its innovative technology, the rotary joints run depressurized while the machine is operating and are pressurized only during the brief periods of tyre pressure adjustment. As a result, the gasket seals of the RDS/portal usually last for the lifetime of the machine.
Moreover, by using special tyre valves, the RDS/portal system offers high operational safety. For example, in the event of a line break, even if the system is activated, the tyres will not lose any air. Unlike 1 line systems, the proven RDS tyre valves immediately close on their own in such an event and prevent the tyres from losing pressure.
With these valves, the tedious closing of the shut off valves in the rims is also eliminated. This was previously required with 1 line technology before driving on the road or parking the machine overnight. This technology is now a thing of the past for New Holland harvesters.
The RDS/portal is supplied by the harvester’s high performance compressor system, which enables tyre inflation in only 2 to 4 minutes, depending on tyre size and the desired change in pressure. Tyre deflation takes approx. 2 minutes.
Operating the RDS/portal 2 line technology is done simply and comfortably using the digital control console in the cab.
