'''MAZ-525''' ('''BelAZ-525''' from 1959) was a Soviet heavy truck produced by the Minsk Automobile Plant. Development started in 1949 at the Yaroslavl Automobile Plant Design Bureau as the '''YaAZ-225'''. It was planned to install a cab from the YaAZ-200, offset to the left. Further technical documentation was passed on to MAZ where the design was substantially enhanced.
==Appearance== The cab appearance changed slightly during production. On the early models, the hood was the same width as the cab; in the later editions, it became much narrower. Initially, a guard was installed on the hood sides for safety while the engine was serviced, but it was later removed.
==Variants== In 1952, the MAZ-E-525D was developed to work in tandem with a {{Convert|15|m3|abbr=on}} D-189 tractor-scraper. In 1954, the joint efforts of MAZ, Institute of Mining and Kharkov Trolleybus Depot developed a trolley dump truck equipped with two D-202 trolleybus electric motors with a total capacity of {{convert|172|kW|hp|abbr=on}}. In 1964, NAMI developed a similar truck called the DTU-25. In 1959, the MAZ-525 was used as a basis for the MAZ-541 aircraft tug, of which three were built. Also in 1959, the MAZ-525A tractor was developed as part of a road train with the 45-ton BelAZ-5271 semitrailer, but this did not enter production because the engine was not powerful enough.
==Production moved== In 1959, production was transferred to the Belarusian Automobile Plant, where the truck was produced until 1965 under the name BelAZ-525.
==Use== The truck continued to operate until the early 1970s.
