Sd.Kfz. 9/1 Famo #2281

The Sd.Kfz. 9 (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 liters (661.4 cu in) HL 108 gasoline engine of 270 horsepower (270 PS). It had a synchromesh ZF G 65 VL 230 transmission with four forward and one reverse gears. It had two fuel tanks, one of 90 liters (24 US gal) and the other of 230 liters (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 Schachtellaufwerk layout 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 version had just two storage compartments mounted in the front of the cargo compartment, one on each side, that opened to the outside. 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 tons (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. It towed Sd.Anh 116 low-loader trailers to carry disabled vehicles.

All were equipped with a winch, mounted at the middle of the vehicle, just under the cargo platform.
