Hi Strum 78,

excuse me, plwase, for my late answer, but it was not so easy for me to translate the text. Here it is:

Distance / span between supports: on the bank 20,7 m; on swimming supports: length of the ferries 24 m; width of the roadway: 5,55 m with two lanes, 3,70 m with one lane.

Supports: bank trestles and 10-piece pontoons, end partspartly with engines (each with 2 Ford V 8 truck engines).

Transport: on railway wagons,to the place of the bridhe trestles on trailers for long wood, pontoons on normal trailers.

Need of steel for one unit: 1300 tons

Capacity of one unit: two lanes 272 m bridge ( 8 ferries + four bank bridges); one lane 322 m (10 ferries + 4 bank bridges).

Building performance: one unit - one engineer batallion 1 to 1 1/2 days

Weight of the heaviest part: end part of the pontoon 3130 kg, motorised end part 5200 kg.

Fitting the bridge: motorised crane, floating the bridge sections by motor boat.

State of development: equipment in use by the troops; available for employment; separate parts in further development, not yet completed.

State of procurement: 3 units model II in use by the troops; 7 units model III in procurement, 2 delivered, 3 end of 1942, rest November 1943.

Thank you very much for your help, Bert... :)

It is a very little known equipment, at least for me.

Hi Sturm 78,

an interesting question. I was comparing the pontoons of all countries in Europe with these Bulgarian ones, but I could find only a similar type of the German Army used during WW I, a so-called "Halbponton" of the "Divisionsbrückentrain".

Best regards

Bert
Thanks too, Bert!

You answered a question that bothered me for quite some time...

Here is the producer data on such Halbponton from National Museum of Millitary History,Sofia:

Hi Angel,

thank You very much for Your reply and posting the very interesting pics of Halbpontons in Bulgarian Museums. The German company Wolf Netter & Jacobi, which obviously produced these Halbpontons, had company seats in Berlin and Strassburg. The producer data: Bauanstalt für Wellblech, Eisenkonstruktion, Verzinkerei, Verzinnerei, Verbleierei (construction institution for corrugated iron, iron construction, galvanising, tinning, lead-coating). During WW I the company changed the production and extensively delivered material for the war, especially pontoons. The second pontoon was produced in 1914 at the beginning of the war. Each division had a so-called Divisonsbrückentrain (division bridge column) with 12 half-pontoons (Halbpontons). Each corps had a Korpsbrückentrain (corps bridge column) with longer pontoons. After the end of WW I the pontoons of the Korpsbrückentrain were used within the Brückengerät A (bridge building material A). Maybe the rest of the existing half-pontoons of the Divisonsbrückentrains were sold to other countries, among them Bulgaria, because I have not seen any pic with such half-pontoons in use of the Reichswehr or Wehrmacht.

Regards

Bert

Hi Bert,

Thanks for the explanations!

According to the official History of Bulgarian Engineer Troops- both the Halbpontons(Divisonsbrückentrain) and the longer pontoons(Korpsbrückentrain/Brückengerät A) were delivered to Bulgaria in Mai 1916, 6 months after my country joined the Central Powers in the Great War.

Here is a picture of the longer pontoon kept at a millitary museum in Bulgaria:

Said museum has also a preserved Pf.11 Pontonwagen from Brückengerät B on display:

Hi Angel,

thank You very much for the pics You posted, especially the pontoon of Brückengrät A. I have also discovered such a pontoon in Neckarhausen on the river Neckar not so far away from Mannheim and made three pics. Here they are.

Best regards

Hello,
that is a very interessting pontoon trailer! Is it possible for you to take a detailpicture of the typeplate. And post it here?
So we can read year of building and the factory.
here is a other example.

best regards

Hi Henning,

I checked all my pictures and the typeplate is nowhere to see...
I'll do my best to find and photograph it next time I go there.

I have a special interest for those Brückengerät B trailers (I am also a scale modeller) and have gathered some information about them.
My country ordered in Oct.1942 2 Brückengerät B sets, together with 32 Henschell 33D1 and 30 Büssing-NAG 4500S trucks to tow the trailers.
These arrived in the summer of 1943.

Cheers,
Angel

Hi all,

here another interesting pontoon of the National Army Museum in New Zealand. It is a German pontoon of WW I, but used by Turkish troops to cross the Suez Canal on 3 February 1915, but they were repulsed by the New Zealand and Indian troops. The Turks suffered heavy losses. The pontoons were taken as ‘war trophies’ and four of them were transported to New Zealand. It appears three have suffered the ravages of time while one has been in storage at the National Army Museum. I think it is a half-pontton like the pontoon on the first pic. Here a pic of this pontoon and also a pic with the inscription panel on the side of this pontoon. Source: https://www.armymuseum.co.nz/blog/artef ... ntoon.html
