The industrial revolution of the late 19th century allowed people to use complex mechanisms to move in space – replacing wind energy or horse-drawn widely used steam energy. A huge number of passengers and various goods were moved with the help of steamships and locomotives. It was the turn to conquer the road, replacing them with a slow-moving horse-drawn carriages and wagons. We already have the first cars, yet rare, expensive, difficult to operate, perceived by many more as entertainment for the rich, rather than the vehicle.
But the increasing pace of life, the development of industry was forced to use cars not only for entertainment but also for transportation. Internal combustion engines were still very far from perfect, difficult to manufacture, and thus did not have the proper traction for the carriage of considerable weight. Therefore, when creating the first truck, many designers have turned to a reliable and proven engine – steam. Trying to translate the locomotives on the road, making them easier and using it for on-road, was quite successful for its time and had a number of advantages over trucks with internal combustion engines. First of all steam engines has been used for almost 100 years, constantly evolving and improving. However, they were still quite simple in maintenance and operation. Unlike internal combustion engines, which used one type of fuel, steam engines are Flex-fuel. Trucks with steam traction for movement demanded water and “everything burns” – coal, kerosene, fuel oil, firewood, sawdust, etc. It was an advantage because the oil industry was still developing, and gasoline was expensive. As coal or wood was available even in the most remote corners of the farms, lumber mills, coal mines.
All this has allowed commercial transport steam-powered to become popular among farmers and Industrialists. Trucks with a steam engine were most common in the 20-30s of the XX century, and was produced and operated until the 50s. One of the most successful and popular manufacturers of trucks for a couple was a British company “Sentinel”. Very often the trucks were produced in single copies for specific needs or were altered from locomotives. But the rapid development of petrol and diesel engines gradually began to displace shrouded in steam steel monsters. Fuel oil has become more accessible, more powerful engines and the trucks easier. Unpretentious promobile, or as they are called “tracks” have contributed to the development of commercial vehicles, serving as a reliable assistant for the carriage of goods and passengers.
