Cat®-Motor Grader 120M2 retrofitted with air brake system

Calle, June 2019. The Graz-based branch of Zeppelin Österreich GmbH are having their Cat® Motor Grader 120M2 retrofitted with Dipl.-Ing. Tietjen GmbH air brake systems. The 20 metric ton, 10 m vehicles can be controlled and safely driven with the compressor roller attachment on roads and doing forestry work in Alpine surroundings.

Thanks to a high production depth, Tietjen GmbH is in a position to produce reliable, exact tailor-made components for this retrofit: Using the latest 3D design software, the Development department first designed the mounts, support plates and plumbing installations which were then manufactured with the company’s own CNC turning and milling machines, a CNC pipe-bending machine and a range of different drilling and punching machinery. These components, as well as others, and 7 m long hoses could be adapted to the available space in the centre pivot steered vehicle with non-contact integration.
 


Training by, with and at Tietjen

We conduct training in schools and colleges, on-site on customer premises, and on our own premises. As well as lessons, training participants also use a training wall to learn how to adjust and simulate all the relevant matters involving the air brake system. Participants can use this simple, flexible plug-in system to get familiar with the functions of all components in practice, and to internalise what they have learnt.
 

We can also carry out training on-site upon request. Our Product developer has also taught at the Technical College for Metals of Hesse. In the preparatory training course for the master's examination, he gave air brake system training to agricultural mechanics.
 


Air brake system for Case IH Quadtrac 540 CVX

Retrofit kit for high-performance articulated track tractor now available from Dipl.-Ing. Tietjen GmbH

Calle, November 2018. Case IH has commissioned development of the air brake system for the Quadtrac 540 CVX track tractor with Dipl.-Ing. Tietjen GmbH. The retrofit kit is available immediately and can be fitted by specialist dealer workshops.

Despite the enormous size of the Quadtrac flagship, engineers at Dipl.-Ing. Tietjen GmbH found it a challenge to integrate all of the components of the retrofit kit, approx. 100 parts, into the existing geometry from the engine compartment to the front. A number of other components had to be assembled in the narrow engine compartment next to the air compressor. Regarding the complex extra electrics, developers worked side by side with Case IH experts and got all the information from them about how to integrate new electrical elements into the existing electrical system.

All the installation steps are documented in the assembly manual including detailed descriptions and diagrams. Workshop dealers can install the retrofit kit with pre-assembled modules, colour-coded connectors and electric components quickly and easily.

Norbert Zehne, Product Manager tractors at Case IH, Germany: “For decades, our Case IH tractor brand has put its trust in the technical solutions of Dipl.-Ing. Tietjen GmbH. Our customers, dealers and ourselves as manufacturer appreciate the quality and flexibility of compressed air specialist Tietjen, especially in After Sales.”

The retrofit kit is available immediately from the Tietjen Online Catalogue.
 


In house production at Dipl.-Ing. Tietjen GmbH

Many of the components in the air braking systems we develop are manufactured in house. This means we can stay independent of suppliers, and reduce delivery times and costs. From time to time we will present the machines for which we manufacture components.

Today: The CNC tube bending machine
The CNC tube bending machine has been in use since 2015. Its primary use is to bend tubes from the compressed air braking system assembly kit, e.g. intake tubes, oil return tubes, pressure oil tubes and brake lines. The machine bends from left to right and from right to left. Tubes of up 6 m in length and 22 mm in diameter are made   more than 10,000 pieces per year. The following video shows how a cooling coil is bent from a 6 m long tube.
 


AGRITECHNICA 2017

Calle, December 2017 – The AGRITECHNICA 2017 is a global meeting place for manufacturers and customers in the agricultural machinery sector.

2,803 companies from 53 countries exhibited their products this year. 450,000 visitors came to Hanover to see them.

This year, Tietjen GmbH focused on the following products:

Electric braking force control (ANEB002 / ANEB003) (full, half, no-load or full and empty load) for trailers with two-circuit air brake systems. ANEB comes as a replacement for the hand controller. The loading status is now very conveniently regulated via a toggle switch in the cab. Individual and precise adjustment of the brake pressures is carried out via pressure reducing valves in the valve unit. This makes the adjustment of the braking pressures to the brake bands provided by the new Regulation (EU) 2015/68 easy to implement.

Vehicle security device OptiLock Drawbar B / Drawbar C: Mechanical locking systems with very high safety level.  The padlock (Drawbar B) and cylinder lock (Drawbar C) makes theft of drawbar trailers almost impossible. In addition, this prevents the coupling of a wrong trailer.

Compressors in three different versions:

  • Compact series: Displacement 120 ccm; flow rate 185 l/min;
    power consumption: max. 1.8 KW
  • Standard series: Displacement 159 ccm; flow rate 280 l/min;
    power consumption: max. 2.8 KW
  • Off Highway series: Displacement 238 ccm; flow rate 370 l/min;
    power consumption: max. 3.8 KW

Tietjen training wall: Shows the combined 1- and 2-circuit air brake system of an agricultural tractor. The training wall gives the possibility to simulate all relevant topics around the air brake system in the classroom.


Air Brake System for Side Loader

Baumann-Side Loader GX 70 is given the extra equipment Duo-Matic-quick coupler and 24 V socket

Calle, August 2017 - Schleifer GmbH from Aßlar in Germany has had Tietjen GmbH develop a pneumatic braking unit for the Baumann-side loader GX70. The loader is also equipped with Duo-Matic quick couplers and a 24 V socket plus voltage doubler. The standard 12 V on-board power supply must be doubled to the 24 V usually found on lorries since the side loader can also pull lorry trailers. The Duo-Matic quick couplers from Wabco join the pneumatic braking system on the side loader with the braking system on the trailer. They allow quicker, safer coupling compared with standard couplings. To make manoeuvring with trailers easier, the Baumann side loader has Duo-Matic quick couplers at both front and rear.


Tietjen GmbH at the Sima

Calle, March 2017 - The French agribusiness show SIMA took place between 26 February and 2 March 2017 in Paris. 1,770 companies from 42 countries presented themselves to an equally international audience.

At the exhibition stand of Tietjen GmbH in hall 4k, experts from the development and sales departments as well as our French distributor Antoine Verzeaux (VERZEAUX SARL) welcomed the visitors and provided them with information about our product portfolio. Interested visitors were able to familiarise themselves with the operating principle of an air brake system and its associated components thanks to our informative training wall, which is an in-house development our own experts created.

Hauke Tietjen, Managing Director, is very pleased about the positive outcome of the trade show: "We established numerous interesting contacts and met with our international business partners. Retrospectively, the trade show was a huge success for us. We would like to use this opportunity to thank all of our customers, business partners and interested visitors who joined us at our stand."

Outlook

Those who were unable to attend the SIMA show will have another opportunity to view the latest development in agricultural machinery and equipment at the Agritechnica 2017 in Hanover from 12 November to 18 November. Tietjen GmbH will be present at their own stand.


Better performance thanks to a more powerful compressor - more volume through the additional air tank

09.02.17 - Tietjen GmbH is now offering a more powerful compressor for 7R series John-Deere tractors – ideal for models with pre-mounted or planned tyre pressure control systems. Compared with capacity of 154 cm³, the new compressor has a capacity of 229 cm³ which represents up to 56 % faster air tank filling time. An extra cooling coil ensures that the temperature does not exceed the input temperature on the air dryer thus ensuring correct functioning of the air dryer.

There is now an additional air reservoir for the 7R tractors with a capacity of 10 l providing a greater volume of air, e.g. for air dryer, tyre inflation systems, and for above-average brake operations such as when driving over hills or when in traffic. The additional air reservoir can be used with both the original compressor and the 229 cm³ model.

Both kits have an installation guide which describes each step in detail using photos. Assembly is thus quick and easy.

For more details about the scope of supply please refer to the product data sheets.

We would be more than happy to answer your questions about these kits
