SdKfz 2 / HK 101

SdKfz 2 (tehtaan tyyppimerkki HK 101), joka tunnetaan paremmin Kettenkradina tai Kleines Kettenkraftradina, on kevyt traktori, joka otettiin alun perin palveluskäyttöön toisessa maailmansodassa kesäkuussa 1941 saksalaisten maahanlaskujoukoissa. Niitä käytettiin mm. Kreetan valtauksen aikana.
Saksalaiset käyttivät Kettenkradeja paljon Pohjois-Afrikassa, Euroopassa ja itärintamalla niiden osoittauduttua hyödylliseksi muussakin kuin alkuperäisessä käyttötarkoituksessaan. Kettenkradiin voitiin myös kytkeä amfibinen perävaunu Sonderanhänger 1 tai 1/2, joka lisäsi kuljetustilaa. 

SdKfz. 2/1 "kleines Kettenkraftrad für Feldfernkabel" ja SdKfz. 2/2 "kleines Kettenkraftrad für schwere Feldfernkabel" -malleilla vedettiin yhteyskaapeleita; niihin oli asennettu kaapelikelatelineet, ja lisäkelojen kuljettamiseen käytettiin Sonderanhänger-peräkärryä. 
Sodan lopulla, kun polttoaineesta tuli pulaa, Kettenkradeja käytettiin erityisesti Me 262-suihkukoneiden vetämiseen lähtöpaikoilleen.

Telaketjujensa ansiosta Kettenkrad pystyi kiipeämään 45-asteisessa kulmassa hiekassa, ja vielä jyrkemmin kovalla maalla. Sodan jälkeen Kettenkradeja valmistettiin vielä noin 550 kappaletta ja käytettiin enimmäkseen maataloustraktoreina, samoin kuin jäljelle jääneitä sodanaikaisia yksilöitä.

The SdKfz 2, better known as the Kleines Kettenkraftrad HK 101 or Kettenkrad for short (Ketten = chain/tracks, krad = military abbreviation of the German word Kraftrad, the administrative German term for motorcycle), started its life as a light tractor for airborne troops. 

The vehicle was designed to be delivered by Junkers Ju 52 aircraft, though not by parachute. The vehicle had the advantage of being the only gun tractor small enough to fit inside the hold of the Ju 52, and was the lightest mass-produced German military vehicle to use the complex Schachtellaufwerk overlapped and interleaved road wheels used on almost all German military half-track vehicles of World War II.

Steering the Kettenkrad was accomplished by turning the handlebars: Up to a certain point, only the front wheel would steer the vehicle. A motion of the handlebars beyond that point would engage the track brakes to help make turns sharper. It was also possible to run the vehicle without the front wheel installed and this was recommended in extreme off-road conditions where speed would be kept low.

The SdKfz 2 was designed and built by the NSU Werke AG at Neckarsulm, Germany. First designed and patented in June 1939, it was first used in the invasion of the Soviet Union in 1941. Later in the war Stoewer from Stettin also produced Kettenkrads under license, accounting for about 10% of the total production.
Most Kettenkrads saw service on the Eastern Front, where they were used to lay communication cables, pull heavy loads and carry soldiers through the deep Russian mud. Later in the war, Kettenkrads were used as runway tugs for aircraft, especially for both the Me 262 jet fighter, and sometimes the Arado Ar 234 jet reconnaissance-bomber. In order to save aviation fuel, A German jet aircraft would be towed to the runway, rather than taxiing under their own power.
The vehicle was also used in the North African theater and on the Western Front.

The Kettenkrad came with a special trailer (Sd.Anh.1) that could be attached to it to improve its cargo capacity.
Being a tracked vehicle, the Kettenkrad could climb up to 24° in sand and even more on hard ground, as long as the driver had the courage for it.


Only two significant sub-variations of the Kettenkrad were constructed. Production of the vehicle was stopped in 1944, at which time 8,345 had been built. After the war, production resumed at NSU. Around 550 Kettenkräder were built for agricultural use, with production ending in 1948 (some sources say 1949).

  1. These are really cool wee vehicles. I can imagine them being very useful after the war!

    2. Good morning Rodger.
      Yes, the contraption is an interesting construction.
      It even has the same engine as the post-war period was a car Moskvitsh
      :) Uses after the war; only imagination acts is border

      I think this is already part of the international contemporary practice...

Any explosive ammunition or empty cores, you can put in this.
