Dür-Wagen

German Empire (1916-1918)
Tracked Supply Vehicle – 10 Built

Few dates in the history of the tank are as important as 15th September 1916, the day that the new weapon was unleashed on the muddy battlefields in France. Usually purporting to be at the forefront of military innovations, the German Army now saw itself confronted with a new and powerful weapon. Understanding the tactical importance and potential of these new landships, German military circles demanded the development of a similar vehicle. In the ensuing tank program, the Dür-Wagen was one of the proposed, but ultimately unsuccessful, solutions.

Development

In an attempt to find a good solution, the German War Ministry commissioned several firms to develop a new tank. One of these was the automotive manufacturer Dürkopp-Werke of Bielefeld, North Rhine-Westphalia.

This firm was co-founded in 1867 by Heinrich Dürkopp and Carl Schmidt and originally known simply as Dürkopp und Schmidt, with Schmidt being dropped from the name in 1876, after he left the firm. It began by manufacturing sewing machines and other household items, but later expanded production with the introduction of shoemaking machines and bicycles. In 1896, Dürkopp also entered the new and lucrative automobile market.

In 1914, after a brief hiatus, the entire production line was dedicated to fulfilling military orders. Motorcycles, ambulances, and trucks were among the produced vehicles. In 1916, wheeled artillery tractors were designed in multiple variants, powered by 4-cylinder engines of 80 and 100 hp, which were put into service in 1917.

In this context, the firm was approached by the War Ministry with a contract to design and build a tracked armored vehicle. While having no experience with designing and building this kind of vehicle, the order was further complicated by the demand that the new vehicle had to be used both as an armored fighting vehicle and as an off-road supply vehicle.

This new vehicle was called the Dür-Wagen, Dür being short for the manufacturer, Dürkopp.

Prototype

Based on appearance, the design team took a hefty dose of inspiration from the Holt caterpillar tractor, in similar fashion to the A7V tank. The reliance on a proven principle is understandable, given the time constraints, as a working prototype was expected in just a few months. The tight deadline was met, however, with the chassis prototype ready for its first tests on 30th January 1917, just four and a half months after the first British tanks were encountered.

During testing, the engineers found that the chassis was too weak to support the mounting of an armored superstructure, thus the idea to build it into a tank was abandoned. Additionally, the vehicle had no specific advantages over the A7V project, so no effort was made to improve the chassis for that purpose. Therefore, it is unknown how the Dür-Wagen would have looked like as a tank, but given the layout, it would have been similar to the A7V.

On 14th May 1917, a demonstration was held in which the Sturmpanzerwagen A7V wooden mock-up, the Orion-Wagen, the Dür-Wagen, and the Treffas-Wagen took part. After these trials, the Oberste Heeres Leitung (Eng. Supreme Army Command, abbr. to OHL) decisively chose the A7V, rejecting the others, including the Dür-wagen.

Design

Also being developed from the Holt design, the layout of the Dür-Wagen was very similar to that of the A7V, except for the engine placement. However, it is unclear what was perceived to be the front or rear of the Dür-Wagen, as the central driver’s position was arranged to allow driving to either side. For simplicity’s sake, this article will consider the engine to be at the front, as this is the same as on the Dürkopp wheeled artillery tractors, and a tow hook was installed on the other side.

The Dür-Wagen was powered by two Dürkopp 80 hp 4-cylinder engines, each powering one track unit, which significantly simplified the steering system. The track unit consisted of a rear-mounted chain-driven sprocket with ten notches to grip to the tracks, a front-mounted idler, a suspension beam with ten road wheels, and a return beam with six return rollers. The tracklinks were very similar to those used on the Holt Caterpillar and the A7V. The vehicle reached a top speed of 14 km/h.

The driver’s position was centered in front of the engine. A bench was placed on either side of the driving controls, to better allow driving to either side. The position was also raised higher than strictly necessary, to allow a better view of the surroundings.

Off-Road Use

Despite the rejection in the tank program, the design apparently had enough merit to warrant the order of ten Dür-Wagens, but as off-road supply vehicles, known as Dür-Geländelastkraftwagen (Eng. Terrain Truck). The suspension was somewhat redesigned to improve its characteristics. Storage space was available to one side of the central driver’s cabin, and on the other side alongside the engine compartment. The sides of the flatbed were outfitted with wooden panels and the driver’s cabin was protected from the weather with an open canopy.

Dürkopp completed all ten ordered vehicles before the end of the war in November 1918 and they saw limited service with the Army, but it is unknown to what extent. After the war, all vehicles were ordered to be scrapped by the Allied Control Commission in 1919-1920, completely erasing this piece of technical history.

This modified picture shows an improved suspension, although never built. The road wheels are divided into two units instead of one, and the idler and sprocket have been raised significantly. Source: Motorbuch Verlag

Further Developments

Dürkopp did not develop any other caterpillar tractors during the war. However, in 1924, its Berlin-based daughter company, Comfräsch A.G., introduced a new agricultural tractor, known simply as the Dürkopp-Comfräsch or Comfräsch-Raupe. It featured an engine-powered mechanical lift that could attach a cultivator or plow. The tractor weighed 2,800 kg and was powered by a Dürkopp four-cylinder engine with 50 hp at 800 rpm. Apparently, only two prototypes were ever built and based on the design, it is unlikely that the older Dür-Wagen was its inspiration.

Conclusion

Little is known about the Dür-Wagen, whose design is a small chapter in the very early German tank development of late 1916 and early 1917. With a weak chassis, the vehicle was only suited as an off-road supply vehicle. The A7V program, on the other hand, was more promising and versatile. Nevertheless, the Dür-Wagen was one of only few tracked vehicles built in the German Empire before 1918.

A7V Schützengrabenbagger LMG Trench Digger

German Empire (1917-1918)
Pioneering Vehicle – 1 Built

Only 20 A7V German tanks were built during World War One but a lot more chassis were constructed. Some were turned into tracked supply vehicles called A7V-Geländewagen and three were used as A7V-Flakpanzer prototype test vehicles. The Germans purchased two standard length Holt caterpillar-tractor chassis at the beginning of their A7V tank development but found they gave poor trench crossing capability so they lengthened one and used that as their A7V tank tracked chassis. All future A7V tracked chassis were built to this extended chassis specifications.

The standard length Holt caterpillar-tractor chassis that remained was converted into a prototype tracked trench digging vehicle. It is believed only one vehicle was produced.

It was used behind the front line to cut trenches. It was not armored in any way so it could not be used anywhere near the enemy. The crew and the vehicle would have no protection from small arms fire and artillery shells. It, therefore, had limited use. It was ideal for cutting defensive frontline trenches and rear communication trenches on pre-planned lines of withdrawal away from enemy fire.

German Pioniertruppe (Pioneer troops) would have used this machine. They were already involved in planning, strengthening and excavating trench systems. This earth digging and moving machine would have made their work easier and got the job done quicker.

The German engineering company Lübecker Maschinenbaugesellschaft (LMG) based in Lubeck in northern Germany was known for building Grabenbaggern earth excavation machines for laying pipes and digging drainage ditches. They mounted their equipment on the Holt caterpillar-tractor A7V tank chassis.

Development of the A7V Chassis

The situation in 1915 – 1916 was dire, as Germany, Britain and France had settled into a stalemate. In order to solve the ‘bloody equation’ formed by the artillery, barbed wire and machine gun combination, both Britain and France began development on a vehicle that had the ability to cross trenches with ease and be able to withstand enemy machine gun fire. This tracked vehicle would eventually revolutionize the battlefield. Thus the tank was born.

Although the tanks suffered from mechanical failures and inadequate crew training they had a major psychological impact on the German soldiers. German intelligence subsequently submitted reports to the Oberste Heeresleitung (German supreme command or OHL for short), which then lobbied the war ministry for an equivalent. However, some of the senior officers of the time were more focused on artillery and infantry tactics rather than the development of the tank or similar armored vehicles.

The committee, headed by chief designer Joseph Vollmer, rejected the trench crossing rhomboid shape track system as used on the British tanks because they wanted to build a chassis that could be used on a tank and a ‘prime mover’ heavy artillery gun tractor. This approach lead to problems.

Two Caterpillar-Holt tractors were obtained and adapted to build a working prototype. It had a better speed than the very slow British tanks but its trench crossing abilities were not as good.

Eventually, the Heeresleitung got some funding from the war ministry to make an equivalent. After months of testing and building, they came up with the A7V. The OHL ordered 100 chassis to be built. The rest were used to develop several A7V variants including the Überlandwagen and an Anti Aircraft version, called the Flakpanzer A7V.

Germany only produced 20 A7V tanks in World War One. Britain and France built over 8,000 tanks between 1916 – 1918. In the battles of 1918 the German Army used more captured British tanks than they did tanks built in Germany.

The Germans were not very imaginative when they gave a name to their first tank. The letters A7V stand for the committee of the Abteilung 7 Verkehrswesen (Department 7, Transport) of the Prussian War Office.

Landwehr Zug

German Empire (1912)
Roadtrain

The brain-child of the famous Professor Ferdinand Porsche, the Landwehr Zug, literally meaning “Land Train”, was one of the first ever hybrid power vehicles. This heavy haulage machine was designed to transport heavy equipment to troops in the field, powered by both diesel and electrocortical drives. There were three versions, each bigger and more powerful than the last. The A-Zug, B-Zug, and C-Zug. They were produced by Austro-Diamler Generator Wagon.

These vehicles entered use in 1912 but would go on to serve through the First and Second World Wars.

Porsche’s Hybrid

Porsche developed his diesel/electric engine in 1900. The first vehicle equipped with this drive was his Semper Vivus road car. It was powered by two gasoline engines that were connected to generators. This formed a charging unit that provided the batteries and motors mounted in the wheel hubs with power. The generators also served as the starter. The vehicle could drive a long distance on electric power alone until the combustion engines were used to charge the batteries. This technology would be used again for the Landwehr Zug, minus the batteries.

The Zug

The assembly of the vehicle started with a small tractor at the head of the train. It held a 100 hp gasoline engine that powered a generator. This provided current to the tractor’s rear axle motors, propelling the vehicle. With the help of a long cable that spanned the length of the train, this generator also provided power to the wheel-mounted motors of the individual carts. This, of course, meant the trailers were self-propelled and not towed, meaning the vehicle was able to traverse the harshest of road conditions with relative ease. Tangled mountain side roads were no issue either as the individually powered carts could handle the tightest serpentine movements.
This power cable also allowed a relatively heavy vehicle to cross weak or temporary bridges. The tractor would go across on its own, the carts would then propel themselves over the bridge one by one. With a small exchange of wheels, the Land Train could become a regular train, able to run on rails.

Larger Zugs

With the A-Zug fulfilling the basic rolls, there was a need for a more powerful vehicle. This gave rise to the B and C-Zug. The B-Zug was more powerful than the previous vehicle, able to transport heavier loads such as light cannons and their heavier ammunition supply. More information on this vehicle is not known, unfortunately.

The C-Zug was the largest of the Landwehr-Zugs and was known as the Artilleriegeneratorwagon. It was designed to make Škoda’s 380 mm (15 in) and 420 mm (16.5 in) siege mortars transportable. For this, the tractor’s generators were powered by a 150 hp gasoline engine. This tractor pulled a single trailer with 8 powered wheels. Fully loaded, this train could weigh up to 38 tons, yet it could still reach the respectable speed of 24 km/h (12.5 mph). This particular vehicle would stay in service into the Second World War.

The largest of the vehicles, the C-Zug or “Artilleriegeneratorwagon”, hauling a large Škoda mortar. This type went on to be used into the Second World War.

Legacy

Porsche would continue to make use of his hybrid design. It would prove an integral part of his later tank designs. This includes the VK 30.01 (P) Medium Tank, the VK 45.01 (P) otherwise known as the Tiger (P) and, later, his crowning glory, the infamous Maus super-heavy tank. The power-sharing system would also be transplanted into these vehicles.

To the “Average Joe”, Porsche is simply known as a luxury sports car producing company. What is much less known is how important one of his earliest developments is. The petrol-electric hybrid is seen as the next step in the life of the combustion engine, but even today, it is still a largely unexplored and sparsely used technology. Only recently has worked really begun again on this type of engine, with vehicles like the Toyota Prius or BMW i8 fitted with this low emission alternative.

Überlandwagen Geländewagen A7V

German Empire (1917-1918)
Tracked Supply Vehicle – 30 Built

The German WW1 rough terrain supply vehicle

Überlandwagen Geländewagen A7V
The situation in 1915 – 1916 was dire, as Germany, Britain and France had settled into a stalemate. In order to solve the ‘bloody equation’ formed by the artillery-barbed wire-machine gun combination, both Britain and France began development on a vehicle that had the ability to cross trenches with ease and be able to withstand enemy machine gun fire. This tracked vehicle would eventually revolutionise the battlefield. Thus the tank was born.
Although the tanks suffered from mechanical failures and inadequate crew training they had a major physiological impact on the German soldiers. German intelligence subsequently submitted reports to the Oberste Heeresleitung (German supreme command or OHL for short), which then lobbied the war ministry for an equivalent. However, some of the senior officers of the time were more focused on artillery and infantry tactics rather than the development of the tank or similar armored vehicles.

The need for a tracked supply vehicle

The battlefield conditions during World War One were horrendous. The muddy, crater filled terrain proved too difficult and at times dangerous for both men and animals carrying supplies being moved to the front. The German Army felt a need to come up with a way of moving these vital supplies quickly but also safely.

In February 1918 the initial modified order for 100 A7V tanks was changed to just 20 finished units. The remaining A7V production chassis was diverted into making prime movers, tracked supply vehicles that could also tow guns and other broken down tanks, and anti aircraft vehicles.
The ‘prime mover’ supply vehicle based on the A7V chassis had a number of different names. The Germans made distinctions between Strassenwagen = Road vehicle. This vehicle crossed rough undulating ground and was called three different names A7V Geländewagen (Terrain vehicle), A7V Rauoenlastwagen (Caterpillar vehicle) and A7V Überlandwagen (Overland Vehicle).

The first eight A7V Geländewagen vehicles (chassis numbers 508 – 515) were completed by September 1917. In November 1917 they were in use with the German Armee Kraftwagen Kolonne (Raupe) III – AKK(R)111 (111th Tracked Army Motor Vehicle Column) in Northern France. By September of 1918 thirty were in services, with the AKK(R)111 and the AKK(R)1122 Army transport columns.

The A7V Überlandwagen’s carrying capacity was approximately 3 – 4 tons (2.7 – 3.6 tonnes). Although it was able to deal with the muddy terrain, it had limited success due its slow speed, poor rough terrain handling and lack of protection for the crew.
Identification number 583 or 588 can be seen on the front of the vehicle
The vehicle chassis number was painted on the right hand side at the front just under the over hanging cargo compartment. Only the number 5 can be clearly seen. This vehicle has a no drivers compartment canopy just wire rails on which a bad weather tarpaulin could be thrown over. It has the taller wooden side panels. The number 8 on a light background in a bordered circle may be the tactical symbol of the German Armee Kraftwagen Kolonne (Raupe) II22 – AKK(R)1122.

Those that did make trips to the front were well received by the soldiers, as the supplies that the Überlandwagen brought intact to the frontline were vital to the men. These supplies would range from clothes to medicine to munitions and at times food. The fate of these A7V Überlandwagens after World War One is unknown, it is possible that they were used sometime afterwards before being broken up and scrapped.

The twin Daimler 100hp engines were mounted side by side in the centre with the driving compartment, arranged for drive in either direction, placed on a platform above the engines. The driver did not have an armoured cab. The seats in the control position swivelled and the controls were duplicated for driving in either direction without the need for turning the vehicle around.

There was a canopy above the driver’s head. In some vehicles rails were added to support a tarpaulin cover over the load spaces. These rails went from the top of the canopy down to the four corners of the vehicle.

The walls of the driver’s cab were only about 2ft (0.6m) tall. He had four large open window that had no glass. In bad weather canvas sheeting was unrolled from the top of the canopy and secured to the bottom of the window opening to give the driver and crew some protection from the elements. The driver and the crew were very vulnerable.

A7V Überlandwagen supply vehicle
This A7V Überlandwagen supply vehicle has a straight end not a boat shaped bow and is not fitted with a cover for the driver.
Unlike the British that used armoured tanks as supply vehicles that could travel right up to the front line under enemy fire, the German A7V Überlandwagen supply vehicles had to stay out of range of Allied rifles and machine guns.
The suspension was derived from the Holt tractor suspension, the American tractor which had also provided the early inspiration for British and French tanks. The A7V-Uberlandwagen had a front and a rear cargo bay, with wooden panels on the side. Later versions had taller panels. For ease of loading and unloading the wooden panels could be unhitched and swing down on their hinges.

Two tow hooks were fitted to the front and back. These were used to tow wheeled vehicles and guns. They were also intended to be used to help tow broken down, knocked out or stuck in the mud German, British or French tanks back to safety.

Vehicle faults

Early reports were favourable but the A7V Überlandwagens suffered from the same mechanical and design problems as the A7V tanks: they had poor cross country performance and low ground clearance. Radiators and backboards were damaged if the load that was being carried was not sufficiently tied down. When the vehicle traversed very undulating ground the heavy load would slide around at fast speeds and hit the sides of the cargo areas causing damage.
The front and back of the cargo area extended past the tracks. This was problematic if the vehicle happened to descend into a big shell crater or trench. The nose of the vehicle got stuck in the mud wall on the other side of the depression. The tracks could not get a proper grip to drive up the wall. This was a design fault.

Fuel consumption was another big issue, especially in 1918 when fuel supplies were low. The A7V Überlandwagen required 10 litres of petrol/gasoline to travel one km. A wheeled truck only required 3 litres of fuel to cover the same distance. As a result they were not heavily used.
