PFEIFER celebrates 440 years of existence

Nowadays, the PFEIFER Group is an international employer with more than 30 sites in 19 countries and ambitious growth targets. We belong to the market leaders in the fields of Rope & Lifting, Rope Technology, Lightweight Architecture and Building Systems. We provide high-tech ropes for the biggest cranes, the highest elevators and cables for the most spectacular stadiums in the world. At the same time, we can look back on such a long corporate history that is possibly unrivalled in the industry.

The rope-manufacturing company of the Pfeifer family was first officially mentioned on February 13, 1579. Which means that today, we are able to celebrate the 440th anniversary of the company. The ropery was operated as a traditional handicraft enterprise by the ancestors of the Pfeifer company in the Old Town district of Memmingen for generations. Production focused mainly on hemp and natural fibre ropes.

Premium supplier

From the 1950s onwards, the former three-man business developed into a modern industrial enterprise. The latest machines were purchased, modern production halls occupied and new employees recruited to mark the beginning of the manufacture of steel wire ropes. This was complemented over the years by additional product segments and business units such as Connecting and Lifting Systems and Lifting Technology. PFEIFER developed into the premium supplier within the industry.

Pioneer of lightweight architecture

At the beginning of the 1970s, the erection of the Olympic Stadium in Munich was the starting signal in the field of lightweight architecture. Today, we are the only company to offer the entire service portfolio in the sector, and now realize modern designer construction projects all over the world.


At the end of the 1980s, the company had already expanded to such an extent that it was accommodated in nine different building complexes in Memmingen. Therefore, a generous, modern factory was occupied in Dr.-Karl-Lenz-Straße, which is still the registered headquarters of our Group today. Then, from the 1990s, the increasing international orientation of the company began.

Motivated team

All of these accomplishments are attributable to a dedicated team of more than 1600 employees and apprentices, who contribute their wealth of know-how every day to our customers and projects worldwide. This passion and expertise are the driving forces of the traditional company PFEIFER since 440 years.

Millennial Reports Positive Pumping Test Results from Second Pumping Well at Pastos Grandes Project, Argentina

Millennial Lithium Corp. (ML: TSX.V) (“Millennial” or the “Company” – is pleased to report encouraging results from an extended pumping test of a second production-scale well at its Pastos Grandes Project in Salta, Argentina. Pumping well PGPW17-04 was installed to complete extended pumping of lithium brine to determine the robustness and chemical variation of the aquifer over 23 days in September, 2018. At a pumping rate of 15 litres/second (L/s), the lithium content remained consistent over the trial period and the drawdown was approximately 57 metres (m), with rapid recovery.  Estimated transmissivity was calculated from the drawdown data at 40m2/day.  The pumping test was completed under the direction and supervision of Montgomery and Associates.

Millennial President and CEO, Farhad Abasov, commented: "Millennial is very pleased with the results of this second pumping test in the central portion of the Company’s land position at Pastos Grandes over a significant 23 day time frame. This is another important milestone in our ongoing development program. The pumping rate was 15 L/s from September 7 to 30th with a draw-down of 57m with full recovery to initial levels after 24 days of recovery. Lithium concentrations remained consistent throughout the pumping test ranging from 482 mg/L to 518 mg/L and averaging 495 mg/l.  The transmissivity of the 40m²/day is encouraging and indicates the aquifer has good potential to sustain long term pumping at 15 L/s  The brine from the pumping test was utilized to feed the large scale pilot ponds currently in operation which will  provide concentrated brine for the Company’s pilot plant scheduled for operation in Q2, 2019. With a strong cash position Millennial is on track to produce an updated 43-101 resource report in Q1 and complete the Bankable Feasibility Study in Q2 2019."

Well PGPW17-04 was drilled using the mud rotary method to a total depth of 475m using 15” and 13.5” diameter drill bits.  The well was completed with 10” and 6” diameter steel pipe with 10” blank pipe for the section from 0m to 113.4m, with 6” slotted pipe for the section from 113.4m to 464.3m and 6” blank casing from 464.3m to 470.4m with an end cap.  The annular space between the borehole and the casing were filled with gravel pack.

Constant flow pumping test was completed with a flow rate of 15.2 L/s with 23 days of pumping and 24 days of recovery water level measurements (See Table 1).  Maximum drawdown was approximately 57m which was achieved after 2 days and full recovery of the well was observed after 24 days.

The drawdown and recovery data provides the basis for the calculation of the aquifer transmissivity, the rate at which the brine moves through the aquifer.  The best estimate of the transmissivity is 40 square metres per day (m²/d) and is considered to be good for fine-grained aquifers.  Based on this transmissivity calculation, the aquifer has good potential to sustain a long term pumping rate of 15 L/s.

Brine sampling during the pumping test was completed every on a daily basis to determine the variation in brine chemical composition over the entire period the aquifer was tested.  In general, the chemistry is consistent over the 23 day period with lithium ranging from 482 mg/L and 518 mg/L and averaging 495 mg/L.  The best lithium values occur during the last five days of the pumping test.  The magnesium to lithium (Mg/Li) ratio averages 5.3 and the average potassium to lithium ratio (K/Li) is 10.5 and the average sulphate to lithium ratio (SO4/Li) is 16.4.

Millennial continues to evaluate and define the characteristics of the lithium-bearing aquifer in the southern portion of its land package with pumping wells PGPW18-15 and PGPW18-17.  Both wells are in development and are planned for completion in Q1 2019 with short term pumping tests and brine sampling to follow. 

Sampling was conducted in accordance with CIM guidelines for brine resource evaluation, with an appropriate chain of custody and QA/QC program in place for ensuring veracity, accuracy and precision of the analytical results.

The primary analytical laboratory for the data used in this program is the SGS Laboratory in Buenos Aires, Argentina.  SGS is accredited to ISO 9001:2008 and ISO14001:2004 for their geochemical and environmental labs for the preparation and analysis of numerous sample types, including brines.

This news release has been reviewed by Iain Scarr, AIPG CPG., Chief Operating Officer of the Company and a Qualified Person as that term is defined in National Instrument 43-101.

19th International Automobile Recycling Congress IARC 2019

New Year, new happiness! We hope you enjoyed celebrating the New Year and that 2019 has started well for you! As you know, time flies and this year’s International Automobile Recycling Congress IARC 2019 will take place in seven weeks. We hope you have already marked the days from 20 to 22 March in your diary.

This year we will again be meeting in the beautiful Austrian capital of Vienna. The preparations have already been completed and we look forward to seeing you again at our annual industry meeting. So, be curious – we promise you another interesting and varied program! Our special thanks go to Manfred Beck, Chairman of the IARC Steering Committee. A few days ago we had the opportunity to talk to him about the forthcoming congress:

• Manfred, the next International Automobile Recycling Congress (IARC) will be held in Vienna in seven weeks. Can you give us an update of the program?

Preparations for the congress are in full swing. The Lecture Committee has again drafted a great program with excellent speakers and interesting topics.

• What highlights can participants look forward to this year?

This year, the IARC has three first-rate keynote speakers who will highlight important issues concerning the automobile recycling industries. Andreas Tschiessner of strategy consultancy McKinsey & Co. will elaborate on ‘Mobility’s Circular Economy Potential’, Johann Prammer of steelmaker voestalpine will address the issue of the steel industry’s technology trends and materials for 2050. And I myself, in my capacity as Chairman of the IARC Steering Committee, will look back on “19 years of the ELV Directive – what has it brought the industry?” Another highlight on the first day of the congress is the panel discussion ‘Opportunities of the Circular Economy‘, with the participation of eight industry experts.

• What will the main topics of this year’s congress be?

Amongst other things, the IARC 2019 will place special emphasis on the following: reuse and recycling, legislation and regulation, sorting and classification, e-mobility and car battery recycling.

• To what extent has the topic of e-mobility reached the automotive recycling industry?

E-mobility is a subject of growing importance to the car recycling industry. Notably the storage, transportation and recycling of lithium-ion batteries have to be carefully studied because safety is a major issue.

• Until a few months ago, global automobile sales were still brilliant, but have weakened in recent months. Must car recyclers prepare for fewer end-of-life cars?

Although global car sales dropped a bit last year, there is no reason for the industry to worry that fewer ELVs will become available to the market. Last year, car sales in Europe even increased for the fifth year in succession, by 0.1% to total 15.2 million vehicles.

This year, for the first time, IARC will present a so-called ‘industry barometer’ in which we ask delegates about their opinion on the state of the industry. We will then be able to give a more detailed answer about the general feeling of actors in the automobile industry.

• Will there be a supporting program apart from the actual congress this year?

Yes, of course. The IARC is organising plant tours to three very interesting companies. The Scholz Austria Group is a market leader in recycling ferrous and non-ferrous scrap, notably in the field of ELV recycling. Isovolta manufactures technical laminates and composites. voestalpine Stahlwelt manufactures, processes and develops steel for high-quality products and innovative solutions. As the plant tours are usually booked out early, we recommend reserving a place well in advance.

• It is a good tradition that the participants are all invited to a networking dinner in a special location at the end of the first day of the congress. What can the guests look forward to this year?

This year, the IARC’s Networking Dinner will again take place in the famous renaissance-style ‚Kursalon‘ music hall. The theme of the evening is ‘Rock me Amadeus’, which is a song recorded by Austrian musician Falco. The song once
topped the singles charts on both sides of the Atlantic. It was Falco’s only number one hit in the United States and the United Kingdom as well as much of Europe. As usual, be prepared for an exciting, fun-packed evening with wonderful food, drinks and music.

So don’t miss this opportunity to exchange news, views and ideas with experts from all areas of the automobile recycling sector. We look forward to welcoming you to this year’s industry meeting. For all the details on the program and how to register, go to:

Successfully master the winding process

Materials in winding applications place varied demands on drives: Sometimes the issue is high speeds, sometimes precision and in other applications, the challenge of a large mass. The wide spectrum of materials covers raw paper with a width of up to ten meters over a thin film, to carbon fibre threads with low elasticity and high tensile resistance.

Paper webs, for example, are rolled with a diameter of around two metres at high speeds of up to 2,000 m/min. Films are sensitive materials which must be wound or unwound extremely precisely, and the winding of metals adds the issue of heavy masses which influence the winding process. One range of drives which embody the required versatility is found in the air motors from DEPRAG SCHULZ GMBH u. CO.

The vane motor works according to a simple principle. The rotor turning in an eccentric cylinder is set into motion. Centrifugal force presses the vanes against the rotor wall and working chambers are built. In these working chambers the compressed air expands, pressure energy is converted into kinetic energy and the rotor turns.

Typical to pneumatic motors is the automatic adjustment of speed when there is a load variation. At idle speed, the air motor works with a complete removal of load. If there is a low load, meaning a low torque on the motor spindle, the working speed is close to the idle speed. The working speed lessens as soon as the torque increases. At 50 % of the idle speed, the air motor reaches maximum power. In this range it is particularly energy efficient.

In comparison with electric motors, the air motors have a high starting torque and can be loaded or even overloaded to standstill with no problems. After a reduction of load, the air motor continues running as normal. An additional advantage is the lessening energy requirements of air motors as the torque increases. In comparison, the electric motor uses the most electricity at maximum torque. Furthermore, compressed air is, in principle an unproblematic energy source: There are no electrical hazards and short circuiting is impossible.

Design to maximum torque

Above all, the required winding speed and the maximum torque are decisive for motor design. For the calculation of the maximum torque, the largest possible reel diameter is taken i.e. the reel in its fully wound state. The winding speed should also be determined at the fully wound state. However, when the reel is carrying less material, the reel diameter is smaller, and the motor automatically winds the material faster – the working speed adjusts to correspond with the load (the lower torque). If the motor is turning too quickly, the speed can be smoothly adjusted by altering the air volume, the operating pressure or a combination of the two.

Speed regulation using air volume

Through regulation of the air volume, speed can easily and flexibly by reduced. Depending on the application either supply or exhaust throttling can be used. Exhaust air throttling reduces the speed of the motor without a noticeable loss of power or reduction of the air motor’s torque. Exhaust air is kept back by a throttle valve, creating a backlog or counter-pressure and the speed is reduced.

If you also wish to reduce the power or torque of the motor, then supply air throttling would be recommended. If, for example, the winding application requires that continuous material be kept taut, then the motor must also continuously receive air.

Speed regulation using operating pressure

The technical data of DEPRAG air drives is based on an operating pressure of 6 bar. Every one of these motors can be operated between 4 and 6.3 bar as required in order to adjust the power needed for the corresponding application. If, for example, an air motor is too “strong” for the paper to be wound, the paper could tear during winding. In this case, a reduction of the operating pressure would be recommended. In combination with supply air throttling, the motor power can be reduced so that tearing is prevented. A reduction of the operating pressure by 1 bar effects a reduction of the torque by 17 %. If the motor is operated at 4 bar, the torque is reduced by 33 %.

In a winding application, an air motor which is operated at 4 bar can still be too strong for a reel which is emptying. In order to further take advantage of the torque range of the air motor, DEPRAG can equip the motor with spring-loaded vanes, so-called forced start vanes. Using these vanes with leg springs, it is even possible to operate the air motor with an operating pressure of less than 1 bar.

ATEX and food safety

The air motors of the BASIC LINE, ADVANCED LINE and POWER LINE series are ATEX conform and authorised for use in potentially explosive areas. Through the expansion of air, any frictional warmth generated is cooled and even under load there is no possibility of overheating the vane motor or igniting gases. The internal overpressure also prevents the penetration of dirt and dust.

Air motors need to withstand cleaning agents and steam for use in food preparation areas, e.g. for packaging machines. ADVANCED LINE motors have external parts made from stainless steel, are sealed and do not require additional housing. DEPRAG air motors can be run without lubrication, i.e. operated with unlubricated air. DEPRAG uses a food legislation compliant lubrication USDA-H1 grease for the planetary gears.

ArcelorMittal Solutions – Think steel first!

Ob Menschen und Land vor Überschwemmungen geschützt werden sollen, oder ob Brücken und Kaimauern für reibungslose Mobilität und Transport sorgen sollen: Stahlspundbohlen von ArcelorMittal bieten intelligente und effiziente Lösungen – einfach und schnell zu installieren, lange haltend und nachhaltig über den gesamten Lebenszyklus der Infrastruktur. Auf der Bauma 2019, der weltweit führenden Baumaschinenmesse vom 8. bis 14. April in München, startet ArcelorMittal seine neue Initiative ArcelorMittal Solutions – Think steel first!, mit der das wahre Potenzial von Stahlspundwandlösungen für das Baugewerbe enthüllt wird. Das kündigt der Konzern heute zum Bauma Media Day in München an. Während der Messe im April wird ArcelorMittal seine Spundwandlösungen in Halle C5, Stand 338, vorstellen.

Stahl ist für die moderne Welt unerlässlich. Stark, flexibel, anpassungsfähig sowie vollständig wiederverwendbar und recycelbar, trägt es nicht nur zur Kreislaufwirtschaft bei, sondern ist das Material der Wahl für nachhaltige Konstruktionslösungen in der heutigen Welt.

ArcelorMittals einzigartige Spundwandlösungen sind auf vier Anwendungsbereiche fokussiert und bieten außergewöhnliche Vorteile, die den Alltag verbessern und eine schnelle, kostengünstige und umweltfreundliche Fertigstellung der Bauprojekte ermöglichen.

Lösungen für den Wassertransport

Beim Bau einer tiefen maritimen Infrastruktur wie Kaimauern und Wellenbrechern mit einzigartigen ArcelorMittal-Spundwandlösungen wie den kombinierten HZ®-M-Wandsystemen und den AS 500®-Rundbohlen können die Lebenszeitkosten des Projekts drastisch reduziert werden. Korrosionsbeständige AMLoCor®-Stahlsorten reduzieren den Effekt der Korrosion um das bis zu 5-fache und ermöglichen so eine länger haltende Infrastruktur. Stahlspundbohlen werden aus vollständig recyceltem und recycelbarem Stahl hergestellt und unterliegen einer Umweltproduktdeklaration. Damit reduzieren sie die Umweltauswirkungen der Projekte.

Lösungen für den Gefahrenschutz

Deich- und Hochwasserschutzbarrieren aus Stahlspundbohlen sind eine der effizientesten Möglichkeiten, um vor Überflutungen und dem Anstieg des Meeresspiegels zu schützen. Spundbohlen können mit geringem Aufwand auch an abgelegenen Standorten mit besonders kurzen Installationszeiten dank AZ®-800, den breitesten Spundbohlen auf dem Markt, problemlos installiert werden.

Die Ingenieurs- und F&E-Teams von ArcelorMittal entwickeln in Zusammenarbeit mit Forschungseinrichtungen und Beratern kontinuierlich Software- und Designmethodiken. Sie helfen bei der Planung von Stahspundwänden und simulieren die Auswirkungen von Erdbeben und Feuer.

Lösungen für die Mobilitätsinfrastruktur

Stahlspundbohlen sind eine hervorragende Option für den Bau von Brücken, Unterführungen, Tiefgaragen, Fundamenten, Stützmauern oder Lärmschutzwänden.

Kurze Installationszeiten und effiziente Installationstechniken ohne Vibrationen helfen dabei, Projekte schneller zu realisieren, Kosten zu sparen und die Auswirkungen auf die Umgebung zu minimieren. Durch den Bau dauerhafter Brückenpfeiler mit Stahlspundbohlen werden beispielsweise Verkehrsbeeinträchtigungen erheblich reduziert, und es werden über die gesamte Lebensdauer des Bauwerks Kosteneinsparungen von bis zu 15% erzielt. Die Verbindung zwischen Beton und Stahl kann mit der VLoad-Software gestaltet werden. Außerdem sind Digitale BIM-Dateien (Building Information Models) für ArcelorMittal-Spundwände verfügbar.

Lösungen für den Umweltschutz

Bei Verschmutzung ist Eindämmung von entscheidender Bedeutung. Spundbohlen werden vorübergehend und dauerhaft für die Deponiebereitstellung, Bodensanierung, Flussbettreinigung oder die Eindämmung von Verunreinigungen eingesetzt. Undurchlässige Einfassungen können geschaffen werden, um kontaminiertes Material sicher zurückzuhalten und einen Sanierungsplan zu erstellen, dank der zahlreichen Dichtungslösungen von ArcelorMittal, einschließlich AKILA®, einem umweltfreundlichen Dichtungsmittel, das für den Kontakt mit Trinkwasser geeignet ist.

So bietet ArcelorMittal maßgeschneiderte Lösungen, die auf die Bedürfnisse ihrer Kunden zugeschnitten sind. Hervorragender Support durch weltweit verfügbare technische Teams unterstreicht den einzigartigen Wettbewerbsvorteil von ArcelorMittal-Spundwandsystemen und führt zu der Schlussfolgerung: ArcelorMittal Solutions – Think steel first!

Fallstudien sind zu folgenden Themen verfügbar:

Tiefgarage in Aalst
Die Stahlspundbohlen, mit denen zuerst die Baustelle abgesichert wurde, dienen jetzt als Außenwände des Parkhauses. Dies zeigt, wie vielseitig Spundbohlen angewendet werden können, zum Beispiel in anspruchsvollen Umgebungen wie dicht besiedelten Stadtgebieten.

Hafen von Køge, Dänemark
Mit AMLoCor®-Spundwänden wurde der Hafen um das Doppelte vergrößert. AMLoCor® ist eine äußerst korrosionsbeständige Stahlsorte, die eine lange Lebensdauer maritimer Infrastrukturen gewährleistet.

Hochwasserschutz, Littlehampton
Das kombinierte Wandsystem HZ®-M erwies sich als die wirtschaftlichste und technisch am besten durchführbare Lösung zur Verbesserung des Hochwasserschutzes in Littlehampton an der Südküste Englands.

Eindämmungs-Struktur, Paris

For the big drive

Safe and accurate transmission of torques is essential for precision drives of cross cutters. This is ensured by the use of steel bellows couplings with force-fitted shaft-hub connection.

The metal bellows couplings of the KXL series from JAKOB Antriebstechnik GmbH were designed for medium and large drives up to a maximum of 65,000 Nm. A special design feature is the three-piece design with a flexible bellows package as an intermediate piece. This removable intermediate piece, consisting of an optimized, torsionally stiff stainless steel bellows with 2 bellows shafts per side and a variable length intermediate pipe, is frictionally connected (screws ISO 4017 / 10.9) with the two hubs. This results in a considerable ease of assembly, as e.g. can be omitted in the maintenance or service case a costly disassembly of the heavy drive or driven units. The designer has several hub variants available for the specific application. The extremely favorable moment of inertia and the rotationally symmetric design ensure good dynamic performance. The KXL couplings are particularly suitable for precise drives, such as for printing presses, cross cutters, main spindle drives, transfer axes or transmission connections. A media transport or a parallel drive train through the coupling interior is basically possible. The connection to the shafts can be done either as a conical clamping ring hub or as a flange hub.

Hub Type A:
Frictional, backlash-free conical clamping ring connection – outside – bellows package radially freely removable. For the overall length "L4", the axial lengthening of the bellows package of 4 mm is already taken into consideration during assembly.

Hub type B:
Frictional, backlash-free conical clamping ring connection – internal bellows package radial NOT freely removable.

Hub Type F / G:
Mounting flange according to ISO 9409 or customer specification – centering outside or inside. Dimensions of flange hub F and G of L13, L19 and D6, D9, D10, D11, D12 according to customer specifications.

Hub Type A / B:
Frictional, backlash-free conical clamping ring connection – outside / inside. Bellows package radially NOT freely expandable
