The story
The company started as a bicycle manufacturer in Anderson, Indiana in 1890. The first trucks (1/2 ton, 20 hp two-cylinder engines) were produced in 1903 and Dart relocated to Waterloo, Iowa in 1907. In 1912 the trucks were redesigned and Dart offered 1/2 ton, 1 ton, and 1 1/2 ton models with four-cylinder engines. By April 1916 seven models were available, ranging from 1/2 ton to three ton. 1925 found Dart in Kansas City, Missouri and named the Dart Truck Company. During World War II the company introduced 10 ton trucks as well as 40 ton tank transporters. They also produced the CC-4 Liberty truck.
In 1958 the company was bought out by Paccar. Dart's trucks continued to grow in size, with 70 ton units produced in the 50s, increasing to 100 ton dump trucks and 120 ton bottom-dump tractor trailers in the 60s, primarily for mining and other off-highway use.
