Talentidest ja "talentidest" - kas 100 aastaga on midagi muutunud?
Karl Parts kirjutab raamatus "Kas võit või surm" Vabjadussõjast ja sellest, kuidas Jürgens jamõnisada talumeest päästsid oma talendiga Petseri rinde ja rahva.
Sillameister Ed. Jürgens. Siin mõni rida sellest kuulsast sillameistrist. Mäletan, kui omalajal formeeriti soomusrongide divisjoni inseneriosakonda. Ei leitud kedagi, kes oleks võinud nii vastutusrikast ja tähtsat tööd oma õlule võtta, mida nõuti soomusrongide divisjoni tehniliselt korraldajalt. Prooviti paigutada sellele kohale mitut tegelikku inseneri, kuid sellest ei tulnud midagi välja. Keegi ei kõlvanud. Katsetatavad osutusid kõik "valgekäe"-meesteks.
Mõnelgi neist oli esimeseks mureks, seada omale sisse korralik kabinett, kus oleks võidud härrana istuda ning jagada välja käske ja korraldusi.
Viimaks peatuti Jürgensi juures. Valik osutus kõigiti õigeks. Tehastesse, depoodesse, töökodadesse, igalepoole, kus häda ja tarvidus kõige suurem, ilmus ta kui keerub oma tulise mõõgaga. Selleks mõõgaks oli jõuküllus, hea tahe, kogemused tehnilisel alal, loomulik taip, suur püüe ja lõpuks suur kohusetunne ning isamaalisus.
Piusa raudteesild oli suurvee ja jää tõttu täiesti purunenud, Petseri rinnet varustada polnud enam võimalik. Tallinnast saadeti välja insenere ja teisi raudtee asjatundjaid. Nende arvamise järele võis silla uuesti üles ehitada kõige varem kolme nädala jooksul. See aeg oli meile aga liiga pikk. Ei oleks jatkunud väeosadel niikauaks ei toidumoona ega ka laskemoona.
Ilmus aga Jürgens Valgast 45 mehega Piusa silla juure ning algas kibe töö. Abiks mobiliseeriti veel ümbrusest mõnisada talumeest. Ööd kui päevad töötati tulise rutuga. Selline kiirtöö kestis viis päeva. Silla pikkus oli 15 sülda ja kõrgus 3,5. Veesügavus 2.5 sülda. Selle suure ja mehiselt juhatatud töö tulemuse oli see, et 18. aprillil kell 12 päeval esimene rong võis sõita üle uue silla.
Tänu divisjoni insener Jürgensile, oli nüüd kõigi Petseri-taguste vahvate väeosade seisukord lõplikult kindlustatud. Olgu sama õnnelik ja edurikas Ed. Jürgensi töö ka kaugel võõrsil, kuhu ta olude tõttu sunnitud on olnud otsima omale uut isamaad.
Ei saa salata, et paarikümne aastaga oleme jõudnud palju edasi, kuid võõraste spetside ja igasuguste võõrastest rahvustest "Wunderkindide" austamine ja kummardamine on meile lausa häbistav.
Kergel käel oleme annud neile ka riigiloonud vabadussõjalaste leivakoorukese (vabadussõjalastele tõotatud kohad).
Peremeheks saanud ori ei oska mõista õigust.

Lembit Merila ehitas elektritarktori kahe kuuga...


Lembit Merila Elektritraktor
see on imeline faktor

Kütet ta ei vaja
mootori mürina asemel saadab laste hõisete kaja

Hooldiskulusid ta ei tunne
aga küladesse toob 6nne

Pagendatud eestlased toob kodumaale
kus Teeme Ära rajab kodusid metsa servale vaiksesse laande

viib võõrpangad Eestist välja
kustutab meie laste nälja

Venelastel oli lahedaid elektrimasinaid.
Mõned nagu kohe sellised mille peale ei tulekski, et seda vooluga tööle panna.

Спасибо за такой фильм Красивая трактора !.

Siemens and Bungartz electric powered machinery

http://www.bungartz.nl/elektra.html


Note: only self-propulsed machinery, no cable drawn ploughs etc. are covered on this page!
For other makes see my other page



plaatje


1912 Siemens 50 hp electric rotary cultivator. This tractor was also made with internal combustion engine, see my Siemens 4 wheel tractors page.

A very early 25 hp electric powered model was shown to the public at the 1914 DLG-show in Hannover.

plaatje


Early Siemens 4 hp (2 kW) electric rotary cultivator, 1000 of these were manufactured. The cable pole could easily be replaced to other plots. The pole was 6 m high, the cable had a lenght of 25 m, enabling tillage of a 1200 m2 field from each pole position. A trailer behind the tiller was available to transport the pole and the power cables from one field to another.
plaatje
plaatje


Where the machinery was not too far from the power supply, it could be directly connected to the electricity wires, which had 120, 210, 380 or 500 Volts AC, or 110, 220, 440 or 500 Volts DC. Siemens-Schuckert supplied special hooks, closing automatically to ensure a good contact.
plaatje
plaatje


If the distance between the power supply and the field was so large that too much power was lost by the cable's resistance, high voltage was used, 5000 Volts AC or more. This solution required a transormator to bring down the voltage to i.e. the 1000 Volts AC which the 60 kW cable plough puller needed.

The distance between transformator and puller was limited by the cable length of 300 m. When furrows of 500 m were ploughed, this meant that 30 ha could be ploughed from one connection point. The electric pullers usually had a petrol engine on board, to provide propulsion from one field to another, where no power connections were available between them.

Siemens electric rotary cultivator, model made from ca. 1928. Obviously they had taken over the Grunder cable system by then.

plaatje


Bungartz U1E with AEG electric motor. In WWII fuel was very scarce in Germany, so Bungartz proceeded where Siemens had stopped experimenting with electric power for tractors. Although this tractor was built after 1945, after the war had ended, petrol engines were used again. The Bungartz U1E was shown on a German DLG-show, I have never seen any electrical powered garden tractors at all. The cable was mechanically wound up on the tractor.

plaatje


Here the Bungartz U1E is shown in operation. It had two speeds, of 1.3 and 5 km/h. The motor power was 5 kW or 6,8 DIN hp.
plaatje


This Bungartz diagram shows that with only 4 power plug connections and a 100 m long cable on the tractor, a 20 hectare plot could be tilled. If another 100 m extension cable was used, only 2 connections were needed for the same 20 hectare. I wonder how many round plots exist in Germany?

Electric powered tiller made by Grunder in Switzerland around 1941. It was powered by a fully enclosed Brown, Boveri motor. Grunder designed this electric powered machine because of lack of oil in Europe during the 1940's.

plaatje


The Grunder could be used with the same attachments as the normal tractors, here it is shown working with a plough. Also visible is how the power was led to the tractor.

plaatje


This is how Grunder imagined the power suppliy to the tractor. Each of the 6 (or more) plots of 1000 m2 could be cultivated. To move to another plot, 1 or 2 pylons had to be replaced. Grunder stated that the cost of electric power was only 1/5 of that of convential fuel, so that the cost of the complete electric installation would be earned back very soon.

plaatje


Balance plough constructed by F. Zimmermann. The electric motor pulls the plough towards each side of the field by means of a chain.

plaatje


Electric powered Töpfer balance plough, built towards the end of WWII by Bungartz representative Töpfer in Teltow, Germany. Power 4½-5 hp at 1400 or 3000 rpm, power supply 380 V. The motor was an AEG, model A4/-2. The machine could work in 2 directions, by reversing the motor, and had 2 speeds by the 2 different speeds of the motor. 100 m of wire could be wound up on the machine.

plaatje


The Töpfer balance plough was further developed after the end of WWII, by Horstmann in Berlin. This is the model E500. Instead of the two speed motor, they chose for a normal gearbox. Only the reverse was still performed by reversing the motor.
plaatje


This Russian tractor is shown in a 1949 Soviet brochure. The electric motor has 39 kW output, the cable has a length of 650 m and connects the tractor to the nearest power pylon.

Agria cultivator of 1951, based on the model 1300.

Electric caterpillar tractor of unknown make. It makes me think of an English Ransomes tractor?
plaatje


Swedish engineer Forssblad modified a normal tractor to electricity. He mounted a 4 m high pole, ca 60 hectare could be ploughed without moving the transformer.

plaatje


Allis-Chalmers used the base of a normal D-12 tractor to construct an electric driven tractor. Not powered through a wire, but by fuel cells. These cell's electrolite produces elctricity if oxygen and nitrogen is supplied. The 112 batteries containing 1008 fuel cells used in the tractors, produced a 60 V current. This was lead to the 20 hp electric motor. By engaging more or less cells, the speed could be controlled. The test tractor still exists in the collection of the Smithsonian Institution in Washington, D.C., USA, and was on show at the Upper Midwest Allis-Chalmers Club.

If all tractors and cars are electro-powered, what happens at the other side of the power plug? (Source: Nieuwe Noordhollandse Courant, 20 July 1991).

I found these pictures on the Internet a while ago, it is supposed to be a RWE tractor from 1953.
