Pro­duced 1951–1965.   After 1959 the pro­duc­tion of this truck moved to BelAZ fac­tory and after that the truck was renamed to BelAZ-525.

The truck was desinged for extreme pay­loads needed in quarries.

MAZ-E-525D — a trac­tor trailer for scrap­per D-189. Loaded scrap­per needed the sec­ond MAZ-E-525 to push it (one 300 hp engine just wasn’t enough!).
Also trol­ley ver­sion was con­structed. It was much more eco­nom­i­cal but needed elec­tric lines to be built. Truck was pow­ered by 2 230 hp DK-202 elec­tric engines.
