The Scania-Vabis L20/L60/L71 was a series of heavy duty trucks produced by Swedish automaker Scania-Vabis between 1946 and 1958.

Truck type of large automobile

A truck or lorry is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power, and configuration; smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful, and may be configured to mount specialized equipment, such as in the case of fire trucks, concrete mixers, and suction excavators.

Sweden constitutional monarchy in Northern Europe

Sweden, officially the Kingdom of Sweden, is a Scandinavian Nordic country in Northern Europe. It borders Norway to the west and north and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund, a strait at the Swedish-Danish border. At 450,295 square kilometres (173,860 sq mi), Sweden is the largest country in Northern Europe, the third-largest country in the European Union and the fifth largest country in Europe by area. Sweden has a total population of 10.2 million of which 2.4 million has a foreign background. It has a low population density of 22 inhabitants per square kilometre (57/sq mi). The highest concentration is in the southern half of the country.

Scania-Vabis’ first post-war model, the L10 had been introduced already in 1944. Two years later came the larger L20, with a six-cylinder variant of the company’s module engine which had been introduced in the late 1930s. The truck was also offered with a trailing axle. This version was called the LS20, with an “S” for "support axle". The largest bogie vehicle had a payload capacity of 10.2 tonnes.

Scania-Vabis L10

The Scania-Vabis L10/L40/L51 was a series of trucks produced by Swedish automaker Scania-Vabis between 1944 and 1959.

Tonne metric unit of mass

The tonne, commonly referred to as the metric ton in the United States, is a non-SI metric unit of mass equal to 1,000 kilograms; or one megagram (Mg); it is equivalent to approximately 2,204.6 pounds, 1.102 short tons (US) or 0.984 long tons (UK). Although not part of the SI, the tonne is accepted for use with SI units and prefixes by the International Committee for Weights and Measures.

Scania-Vabis L60

At the end of 1949, Scania-Vabis introduced a direct injected diesel development of their module engine. It had been designed in collaboration with British truck manufacturer Leyland Motors. [2] With the new engine, the six-cylinder truck got its name changed to L60 and LS60 respectively. Otherwise the truck was mostly unchanged. In 1951 the old fashioned non-synchro four-speed gear box was replaced by a synchronized five-speed transmission.

Leyland Motors Limited was a British vehicle manufacturer of lorries, buses and trolleybuses. The company diversified into car manufacturing with its acquisitions of Triumph and Rover in 1960 and 1967, respectively. It gave its name to the British Leyland Motor Corporation, formed when it merged with British Motor Holdings in 1968, to become British Leyland after being nationalised. British Leyland later changed its name to simply BL, then in 1986 to Rover Group.

A non-synchronous transmission is a form of transmission based on gears that do not use synchronizing mechanisms. They are found primarily in various types of agricultural and commercial vehicles. Because the gear boxes are engineered without "cone and collar" synchronizing technology, the non-synchronous transmission type requires an understanding of gear range, torque, engine power, range selector, multi-functional clutch, and shifter functions. Engineered to pull tremendous loads, often equal to or exceeding 40 tons, some vehicles may also use a combination of transmissions for different mechanisms. An example would be a power take-off.

Scania-Vabis L71 Regent

In the spring of 1954 the final development of Scania-Vabis’ six-cylinder module engines were introduced, with larger displacement. [3] The trucks were renamed L71/LS71 Regent and received air brakes. From the autumn of 1955 they could also be ordered with power steering.

Air brake (road vehicle) type of friction brake for vehicles

An air brake or, more formally, a compressed air brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad needed to stop the vehicle. Air brakes are used in large heavy vehicles, particularly those having multiple trailers which must be linked into the brake system, such as trucks, buses, trailers, and semi-trailers, in addition to their use in railroad trains. George Westinghouse first developed air brakes for use in railway service. He patented a safer air brake on March 5, 1872. Westinghouse made numerous alterations to improve his air pressured brake invention, which led to various forms of the automatic brake. In the early 20th century, after its advantages were proven in railway use, it was adopted by manufacturers of trucks and heavy road vehicles.

In automobiles, power steering is a device that helps drivers steer by augmenting steering effort of the steering wheel.

Tow truck truck used to move disabled, improperly parked, impounded, or otherwise indisposed motor vehicles

A tow truck is a truck used to move disabled, improperly parked, impounded, or otherwise indisposed motor vehicles. This may involve recovering a vehicle damaged in an accident, returning one to a drivable surface in a mishap or inclement weather, or towing or transporting one via flatbed to a repair shop or other location.

Automotive industry in Sweden

The automotive industry in Sweden is mainly associated with passenger car manufacturers Volvo Cars and Saab Automobile but Sweden is also home of two of the largest truck manufacturers in the world: Volvo AB and Scania AB. The automotive industry is heavily dependent on export as some 85 percent of the passenger cars and 95 percent of the heavy vehicles are sold outside of Sweden. The automotive industry and its sub-contractors is a major part of Swedish industry. In 2011 around 110,000 people were employed and the export income of 150 billion SEK accounted for 12 per cent of Sweden’s export income. During 2009 128,738 passenger cars and 27,698 heavy vehicles were built in Sweden.
