Nesselsdorfer Wagenbau-Fabriks-Gesellschaft (NW) First Truck is a veteran truck manufactured by Nesselsdorfer Wagenbau-Fabriks-Gesellschaft A.G. (now known as Tatra) in 1899. The unique feature of the engines setup was that the two engines could be operated sequentially depending on the load requirements. After the company finished its first passenger car, named the Präsident, it focused on manufacturing a truck. The First Truck represents the beginning of the long tradition of Tatra commercial vehicles. ==Design== The truck was a flatbed with covered loading area and with a top over the personnel compartment, which could seat two. The loading area was x and had 2,5 tons capacity. There are poles in its corners, which carry the roof, most of the rear face wall middle part is tiltable (similar to low divided side wals) as a flatbed rear loading ramp. The seat for two is in front of the loading area. The front axle carries the iron frame via two elliptical leaf springs. The wooden front wheels have steel rims with outer diameter of . The steering column is on the right in front of the driver. The rear axle is sprung by two couples of spiral springs. The wheels are wooden with steel rim and outer diameter of . The vehicle has two two cylinder flat 120 x 120 mm liquid cooled Benz engines (the same as the 1st Präsident passenger car), which are mounted under the frame behind the rear axle. Uniquely, the engines could be operated sequentially depending on the load requirements. No 1 engine was started via a cranking handle and had a flywheel attached and No 2 engine without the flywheel was connected via a gear clutch and started by the first engine already running. The second engine could be started or switched off anytime during the drive. Switching off the second engine cuts the fuel consumption in half. Another interesting detail is the both engines vapour cooling - coolant fumes are led to the roof condenser and the water is recycled back into the coolant tanks placed in the vehicle rear what lowers the water consumption. The gear box is mounted under the frame in front of the rear axle. The gears are changed through two gear sticks in front of the driver. The truck has 3 gears forward and reverse. It was able to reach 20 km/h.〔 〕 The fuel consumption was 4 kg of petrol per 100 km and it was able to climb 12° angle.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NW First Truck」の詳細全文を読む スポンサード リンク
