s. Zgkw. 12 t (Sd. Kfz. 8): Heavy Semitrack Prime Mover

s. Zgkw. 12 t (Sd. Kfz. 8): Heavy Semitrack Prime Mover

The 12-ton heavy prime mover is highly mobile despite its bulky appearance. It can handle a trailer load of 13 tons and carry a crew of 11, including the driver. It has a weight distribution as follows: front wheels, 5,200 pounds; track, 21,300 pounds. Its combat weight is 16 tons.

The front suspension consists of a tubular axle of the oscillating, floating type carried by two pressed steel wheels, size 11.25 x 20, mounting extra heavy-duty tires. A traverse leaf spring is on a pivot in the center of the frame. One end of the spring is mounted to the axle through a shackle while the other end is free to slide. The rear, or track suspension, is made up of six twin rubber-tired bogie wheels mounted on torsion arms, attached to torsion bars and housed in cross tubes. The front drive sprocket and rear idler complete the assembly. The track is of the needle-bearing type with removable rubber pads.

Steering is by conventional steering wheel and through epicyclic-controlled differential to the track sprockets, being actuated by hydraulic brake bands.

Power is furnished by a Maybach V-12 over-head valve, liquid-cooled, HL 85 TUKRM gasoline engine, rated at 185 horsepower. Ignition is the conventional 12-volt Bosch magneto located behind the carburetors. All ignition wires are carried in a flexible aluminum conduit to the side of the engine.

The transmission provides four speeds forward, one reverse, with high and low range.

This vehicle is equipped with an inertia starter and a cable winch with a lifting power of 5.5 tons.

7.5 cm Pak 40: Antitank Gun

7.5 cm Pak 40: Antitank Gun

The Pak 40, an antitank and antipersonnel weapon, has a barrel of monobloc con­struc­tion to which is screwed a two-baffled muzzle brake. The horizontal sliding type breechblock operates semi-automatically. Recoil and counterrecoil are effected by means of a hydraulic buffer and a hydropneumatic recuperator.

The welded steel carriage has tubular trails, light alloy steel wheels with solid rubber tires, and a 5 mm spaced armor shield for the protection of the gun crew. There are two types of brakes: air brakes, which are operated from the prime mover, and hand brakes for placing the gun in firing position.

Although no sighting equipment was captured with the gun, it is assumed that there was a telescopic sight for direct fire, a sight for indirect fire, and an auxiliary open sight. Mounts for these sights are attached to the breechring and the left trunnion.

There is also a gun known as the 7.5 cm Pak 97/40. This gun consists of a French Model 1897 piece mounted on the carriage of a German 7.5 cm Pak 40, but usually on Pak 38 carriage.

A modification of this gun is used on the chassis of the Pz. Kw. II tank and the Czech Pz. Kw. 38 (t) converting these vehicles into gun motor carriages.

The 75 mm tank gun, KwK. 40, used in Pz. Kw. IV is an adaptation of the Pak 40.
