Freightliner Trucks, an American traditional company based in Portland, operates in the commercial vehicle market and is now owned by the automotive giant Daimler. It is primarily known as one of the leading manufacturers of tractors. However, it should not be forgotten how widespread and successful Freightliner trucks have been over time for heavy-duty applications. In fact, the market for quarry vehicles experienced significant growth in the late 1970s and early 1980s, which impacted the production volumes of major truck manufacturers. The engineers at Freightliner have worked on the best technical solutions for the demands of the construction market: reinforced chassis and rear axles for higher load capacity, highly durable dump bodies, as well as engines and transmissions optimized for demanding loads and steep inclines.
