    RDS/GW 2L with digital or isobus control

    2 line tyre inflation system for all slurry tankers and trailers

     

    The RDS tyre inflation system 2 line technology is a proven and reliable system for comfortably adjusting tyre pressure while the vehicle is moving. The lines are led through the bored axles. This system is suited for all slurry tankers and other trailed vehicles with similarly prepared axles. A retrofit with the RDS 2L is not possible unless the axles come pre-bored since subsequent boring of the axle would result in voiding the axle’s operating permit!

     

    Air is led to the tyre through the bored axle before arriving in the compact 2 line rotary joint that has been screwed into the front side of the axle hub. This rotary joint is unique for its being maintenance-free thanks to its high-quality rotary seals and ball bearings being provided with a special lifetime grease filling.

     

    The sealing system for sealing the grease cap was developed in cooperation with BPW. In the rim, a wheel valve with check functionality is installed that will immediately close in the event a line tears and will keep the tyre from losing pressure.

     

    The system is connected via a safety valve to the air brake system so that 6.5 bar (94 psi) of pressure supply in the air brake reservoir is guaranteed at all times.

     

    Due to the large volume of the tyres on the vehicle, the use of separate/additional air supply systems is usually necessary. PTG offers various air supply systems that turn on and off automatically as needed.

     

    Operating the system is done from the cab and can be done with either digital or isobus control

    2 line tyre inflation system for slurry tankers and trailers

     

    In principle, the AIRBOX/drive 2 line technology works by transferring air from a stationary component (stator) to a rotating component (rotor). For this process to work, pressure-resilient gasket seals are installed in the stator that in interacting with the rotor cause annular channels through which the air pressure flows, of course, also while the vehicle is moving.

     

    The rotary joint is screwed onto the wheel studs concentrically to the middle axle using a fitting stirrup. Rotor and stator are embedded lined up with one another. Both a large line and a small control line rotate synchronously with the rotor and are led to the tyre valve.

     

    In the rim, a Wheel valve with check functionality is installed that will immediately close in the event a line tears and will keep the tyre from losing pressure.

     

    Due to the large volume of the tyres on the vehicle, the use of separate/additional air supply systems is usually necessary. PTG offers various air supply systems that turn on and off automatically as needed.

     

    The rotary joints and the entire air line system at the front and rear axles are pressurized only during an active control cycle. The patented two-line principle ensures that after every pressure change the tyre is closed off and all transfer units (including gasket seals) are depressurized, thereby sparing the system from unnecessary wear.  This technology also sees to it that the tyre loses no air in the event of a leak in the regulating system or a break in the line, thereby guaranteeing increased safety.

     

    The air lines run to the tyre over the fender through a telescopic tube and are led to the middle of the wheel. Using the telescopic tube, the clearance to the side of the rotating wheel can be individually adjusted.

     

    The large line and the control line are connected to the rotary joints using quick-action couplings so that they can be easily removed when not in use and placed on the fenders in dummy couplers.

     

    Operating the system is done from the cab and can be done with either digital or isobus control

    RDS 1L with pneumatic control

    1 line tyre inflation system for slurry tankers and trailers

     

    The RDS tyre inflation system 1 line technology is a proven and reliable system for comfortably adjusting tyre pressure while the vehicle is moving. The lines are led through the bored axles. This system is suited for all slurry tankers and other drawn vehicles with axles that came pre-bored from the factory. A retrofit with the RDS 1L is not possible unless the axles come pre-bored since subsequent boring of the axle would result in voiding the axle’s operating permit!

     

    Air is led to the tyre through the axle. The compact 1 line rotary joint is screwed into the axle hub. This rotary joint is unique for its lifetime grease filling (tedious refillings become no longer necessary), high-quality rotary seals and ball bearings. The sealing system for sealing the grease cap was developed in cooperation with BPW. A ball valve is mounted in the rim that must be closed by hand after the vehicle has been parked.

     

    Due to the large volume of the tyres on the vehicle, the use of separate/additional air supply systems is usually necessary. PTG offers various air supply systems that turn on and off automatically as needed.

     

    In selecting the right air supply system for you we will gladly help you with one of our detailed air requirement calculations.

     

    The system is connected via a safety valve to the air brake system so that 6.5 bar (94 psi) of pressure supply in the air brake reservoir is guaranteed at all times.

     

    Operating the system is done from the cab using the control console of the pneumatic control.

    AIRBOX/drive 1L with pneumatic steering

    1 line tyre inflation system for slurry tankers and trailers

     

    The AIRBOX/drive 1 line technology is a “retrofit system” with which you can comfortably adjust tyre pressure from the cab while the vehicle is moving. Without the tediousness of stopping and dismounting, drive with low tyre pressure in the field doing the least amount of harm to the soil and on the road with high tyre pressure saving fuel and doing the least amount of wear to the tyres. It is suited for all agricultural trailers and designed for self-installation.

     

    In principle, the AIRBOX/drive 1 line technology works by transferring air from a stationary component (stator) to a rotating component (rotor). For this process to work, pressure-resilient gasket seals are installed in the stator that in interacting with the rotor cause annular channels through which the air pressure flows, of course, also while the vehicle is moving.

     

    The rotary joint is screwed onto the wheel studs concentrically to the middle axle using a fitting stirrup. Rotor and stator are embedded lined up with one another. A large line runs from the rotor to the synchronously rotating tyre valve.

     

    A ball valve is mounted in the rim that must be closed by hand after the vehicle has been parked.

     

    The air line is led to the tyre over the fender through a telescopic tube to the middle of the wheel. Using the telescopic tube, the clearance to the side of the rotating wheel can be individually adjusted.

     

    The large line is connected to the rotary joints using quick-action couplings so that it can be easily removed when not in use and placed on the fenders in empty coupling points.

     

    The system is connected via a safety valve to the air brake system so that 6.5 bar (94 psi) of pressure supply in the air brake reservoir is guaranteed at all times.

     

    Due to the large volume of the tyres on the vehicle, the use of separate/additional air supply systems is usually necessary. PTG offers various air supply systems that turn on and off automatically as needed.
