The BelAZ-549 is a mining dump truck built by the BelAZ from 1968 to 1988. Many engines were used with this chassis and it also served as basis for the experimental one-axle semi-trailer tractor BelAZ-549V.

The BelAZ-549 traded its M-300 engine mid-production for the 6ChN 21/21¹⁾.

• Engine:

The BelAZ-549B is fitted with a 6-cylinder 6RA4-185 engine.

Similarly to the BelAZ-548 and BelAZ-548V, the BelAZ-549V is a one-axle semi-trailer tractor based on the BelAZ-549. It was designed to work in combination with the BelAZ-7525 trailer.

The BelAZ-549S is a thermally adapted BelAZ-549 for polar exploitation.

In 1973, the BelAZ built the BelAZ-7420 semi-trailer tractor based on the BelAZ-549. It was to be used in combination with the BelAZ-9590 dump trailer for coal transporting.

In 1975, the BelAZ-549G was used as a chassis to experiment a new gas-turbine engine.
