PTG Tyre Inflation Systems

PTG tyre inflation systems are suited for all types of vehicles and for any trailer:

 

Starting with the AIRBOX/mobile for stationary adjustment axle by axle up to our RDS system for fully automated adjustment on the move.

 

For more than 25 years, this has been the standard for all our systems:

 

Modern manufacturing, permanent quality control and constant research and development guarantee the highest level of reliability. This has made us one of the world market leaders and the preferred outfitter for agricultural vehicles.

 

Patents protect our inventions against cheap imitations.

 

Familiarize yourself on the following pages with the advantages of adjusted tyre pressure and our current line of products. We will also gladly develop an individual solution for you .

  • The need for the right tyre pressure  more >>

    Today’s tractor is a tool, the capabilities of which have increased dramatically in the last few years. At speeds of up to 60kph, moving the machine quickly from field to field as well as transport operations on the road are possible; during all of which, heavy loads on the rear axle often also need to be supported by the tyres.

     

    The tractor is required to

     

    • safely and quickly complete the drive

     

    • powerfully accomplish the work in the field and preferably do little harm to the soil

     

    • do it all with the least amount of tyre wear and fuel consumption

     

    The tyre constitutes the link between machine and the ground (field/road) and has to take on multifunctional tasks:

     

    • On the road it should be stiff and roll with little wear.

     

    • In the field it should grip smoothly, gently and evenly.

     

    Two demands that effectively contradict one another!

     

    Demand 1:

    On the road it should be hard and roll with little wear, which is possible only with a high tyre pressure.

     

    Demand 2:

    In the field it should grip smoothly, which is possible only with a low tyre pressure.

  • Advantages/Benefits of high tyre pressure on the road  more >>

    On the Road with high tyre pressure:

     

    Considerably smaller tyre footprint.

    Note: the tyre walls are stabilised

     

    • High load capacity at high speeds

     

    • Increased directional and drive stability

     

    • Greater safety in traffic since travel with too little air in the tyres is avoided

     

    • Less fuel consumption (15 % and more) due to rolling resistance on the road

     

    • Less tyre damage
  • Advantages/Benefits of low tyre pressure in the field  more >>

    In the field with low tyre pressure:

     

    Considerably large tyre footprint.

    Note: The tyre becomes only minimally wider, but notably longer.

     

    • reduced ground contact pressure

     

    • reduced tyre rut depth

     

    • reduced rolling resistance

     

    • no/less damaging ground compaction

     

    • increased yields

     

    • considerable increase in traction capability due to the tyres’ better grip of the ground
  • Tyre pressure and tyre tracks in the field  more >>

    • fuel consumption in the field (10 Reduced % – 15 %)

     

    • example: 5 cm rut depth corresponds to a constant rise of a 5 % grade!

     

    • reduction of wheel slippage up to 20 %

     

    • less dependence on the weather in the event of urgent field work

     

    • extended hours of seasonal operation

     

    • more effective self-cleaning of the tyre tread via the flexing of the tyres

     

    • active health protection for the operator through reduced body vibration

     

    • less tyre damage

    Tyre pressure adjustment while the tractor is stationary

     

    AIRBOOSTER

    Manual pressure adjustment; adjusted in each tyre one after another.

     

    AIRBOX/mobil

    Semiautomatic, adjusts on its own the pressure in all tyres connected to the system to the selected value.

     

    Tyre pressure adjustment while the tractor is in motion

     

    RDS/AS 2L – for tractors with bar axles

    Radial rotary joint on the inner side of the tyre.

     

    AIRBOX/drive 2L & AIRBOX/drive 1L – for tractors and trailers

    Rotary joint on the outer side of the tyre, air is led over the fender

     

    RDS/GW 2L & RDS/GW 1L – for trailers

    Air is led centrally through the axle. Ideal for all drilled, non-drive axles.

     

    RDS/portal 2L – for harvesters with portal axles

    Air is lead centrally through the axle.
