MAZ-530

The MAZ-530 was a Soviet heavy-duty dump truck with a 6x4 wheel arrangement, produced at the Minsk Automobile Plant from 1957 to 1960 and then at the Belarusian Automobile Works until 1963. It was created in the mid-1950s as a larger successor to the two-axle MAZ-525, keeping a similar layout but adding a third axle, with two driven rear axles on an equalizer suspension, a box-beam frame and oversized 18.00-32 tyres, which raised payload capacity by 15 tons. Power came from a V-shaped 12-cylinder D-12-450 diesel of 450 horsepower. The first prototype was ready in March 1957 and was shown at the All-Soviet Agricultural exhibition in Moscow, and the 1958 truck won the Grand Prix at the World Industrial Exhibition in Brussels. It was the first and only 6x4 heavy dump truck in the USSR and had few comparable rivals outside the United States, but its layout was already outdated by the 1960s, so it was discontinued after only about 30 units and no examples remain.
