FAMO - Schwerer Zugkraftwagen 18 t - SdKfz 9 - Crane and cargo version - a case report

     Kollegen!!! 
      I have an addiction: build similar kits in pairs, to save time and research ...
Sdkfz 9 cargo and crane version towing a Tiger
      So, I'll show to you guys a couple of gorgeous German twins girls; Similar, but not identical ...

      Uops...wrong pic... The correct is this Tamiya girl, in two versions, in double building:
Schwerer Zugkraftwagen 18 t SdKfz 9 - FAMO. 

Tamiya FAMO
      As I had two of these kits in my closet, I decided to build this pair at once (in 2010). But, first of all, let us know the history of this big lady.

History:
      The Sd.Kfz. 9 Schwerer Zugkraftwagen (also known as "Famo" ) was a German half-track that saw widespread use in World War II, and the heaviest half-track vehicle of any type built in quantity in Nazi Germany during the war years. Its main roles were as a prime mover for very heavy towed guns such as the 24 cm Kanone 3 and as a tank recovery vehicle. Approximately 2,500 were produced between 1938 and 1945.

      The Sd.Kfz. 9 had a ladder frame chassis. Power was provided by a Maybach 12-cylinder, water-cooled, 10.838 litres (661.4 cu in) HL 108 gasoline engine of 270 horsepower (270 PS). It had a syncromesh ZF G 65 VL 230 transmission with four forward and one reverse gears. It had two fuel tanks, one of 90 litres (24 US gal) and the other of 230 litres (61 US gal) capacity.
      Both tracks and wheels were used for steering. The steering system was set up so that shallow turns used only the wheels, but brakes would be applied to the tracks the further the steering wheel was turned. The drive sprocket, like all German halftracks, had rollers rather than the more common teeth. The rear suspension consisted of six double sets of overlapping, interleaved roadwheels mounted on swing arms sprung by torsion bars. An idler wheel, mounted at the rear of the vehicle, was used to control track tension. The front wheels had leaf springs and shock absorbers.

      The upper body had a crew compartment common to all versions. This had bench seats, one for the driver and his assistant, and another for the crew. The rear portion of the upper body was adapted for the vehicle's intended role. The artillery model had two extra bench seats for the gun's crew and space for its ammunition.

       The cargo or towing version had just two storage compartments mounted in the front of the cargo compartment, one on each side, that opened to the outside.


FAMO SdKfz 9 towing version
      The windshield could fold forward and was also removable. A convertible canvas top was mounted at the upper part of the rear body. It fastened to the windshield when erected.
      The Sd.Kfz. 9 was designed to have a towing capacity of 28 tonnes (28 long tons; 31 short tons). This was adequate for medium tanks like the Panzer IV, but two or even three or four were necessary for heavier vehicles like the Tiger I, Panther or King Tiger.

      Preliminary design of all the German half-tracks of the early part of the war was done by Dipl.Ing. Ernst Kniepkamp of the Military Automotive Department (Wa Prüf 6) before the Nazis took power in 1933. His designs were then turned over to commercial firms for development and testing. Fahrzeug- und Motorenbau GmbH (FAMO) of Breslau received the contract for the 18 t (18 long tons; 20 short tons) heavy towing tracked vehicle. Their first prototype, the FM gr 1, was completed in 1936. It had a 200 horsepower (200 PS) Maybach HL 98 TUK engine and was only 7.7 metres long. The F 2 prototype appeared in 1938, but differed only in detail from its predecessor.
      The F 3 appeared in 1939 and was the production version. The design was simplified over the course of the war to reduce costs and the use of strategic metals. Some vehicles produced by Tatra had its 12-cylinder, air-cooled Type 103 diesel engine fitted. Large spades were added at the rear of the chassis during the war to improve the vehicle's ability to recover tanks and other heavy vehicles.
      A new upper body was used for the Sd.Kfz. 9/1 which mounted a 6 t (5.9 long tons; 6.6 short tons) capacity crane in lieu of the crew's bench seat and the cargo compartment. It was issued to tank maintenance units beginning in September 1941.

 A larger, gasoline-electric, 10 t (9.8 long tons; 11 short tons) crane was fitted on the laterSd.Kfz. 9/2, but this required outriggers to stabilize the vehicle before operations could begin.

      Some 8.8 cm Flak 18 anti-aircraft guns were mounted on fifteen Sd.Kfz. 9s in 1940 as the 8.8 cm Flak 18 (Sfl.) auf Zugkraftwagen 18t (Sd.Kfz. 9) for anti-tank duties. The crew and engine compartments were lightly (14.5 mm), but completely, armored, which limited the gun's ability to fire directly ahead. A platform with drop-down sides was fitted for the gun. Outriggers were necessary to brace the platform sides to support the weight of the gun crew. The vehicle weighed 25 tonnes (25 long tons; 28 short tons), was 9.32 metres long, 3.67 metres tall and 2.65 metres wide. One source claims that these vehicles were produced as prototypes in 1943.

      Vomag of Plauen began producing the Sd.Kfz. 9 in 1940 and Tatra joined in the last years of the war. 855 were on hand on 20 December 1942. 643 were built in 1943 and 834 in 1944. Approximately 2,500 were built in total.

The kits:
      As I say, to do this double project, I used two FAMOs from Tamiya.  Old kits, but very good and easy to build. My idea was to use a Bilstein crane in resin, which had built years ago and that was leaning in a corner of my workshop, waiting for the right carrier ...The other FAMO would be a cargo version.
Bilstein 6 ton. crane - resin - Panzerserra's kit.
     
      For the crane version, I had to transform the kit Tamiya through plastic surgery. There are conversion kits on the market, but I like doing things on scratch ... It's part of the fun! This picture  below was my inspiration. Notice the crane's base (rigid) and a toolbox in the rear of the loading platform. These are characteristics of the early versions of the SdKfz 9/1.
SdKfz 9/1 - early version
      The later versions had a joint at the base of the crane and did not bear the toolbox in the aft.

      Well, starting the fun...Engines: As I would leave the engines exposed, I sweat in the detailing and painting
Gentleman, start your engines....

       For now, the building of the girls are in parallel ... soon, they will differentiate.
The snouts of the FAMOs...
       And now, the buildings will differentiate enough. Notice the differences between the tractor version and crane version.
observe the red arrows ... all this will be removed and the side,  cut

      And the cabins built ... Compare the two girls:
The two cabins..Notice the differences!!!
       In the crane version, I cut the back part of the cabin, just to seize the support of the cab in the chassis. I cut in the green arrows and discarded the part in scratched red.
I used only the lower portion of the part
After cutting, testing  the  cabin's support in the chassi

Notice the air filter in place (red arrow) and the cargo beds painted
          For the crane version, I made a new plate in the cargo bed. Scratch with plasticard...

I used scrap Photo-etched and rivets made with sprue. The scribing was easy...The crane place was cut with compass...
      The Bilsten crane resin kit came with parts to adapt the crane to FAMO or a Bussig-Nag. I kept these parts and I used them to complete the assembly in my FAMO...

Adding the seats !!!
Seats in the crane version. Notice the drums...
I had to redo the wiring crane, because the boom is fixed in its support.


     I chose for my crane version the markings of 10th Panzer Division. As I did not have decals of these markings, the simbols were made with brush and steady hand...
The Bison of 10th Panzer division
