The invention is applicable to the technical field of rail transit, and provides a suspension type monorail single-shaft single-beam flat turning turnout. The turnout comprises a supporting assembly and a moving assembly, the supporting assembly comprises a base plate, first guide holes and limiting grooves, the first guide holes are formed in the surface of the base plate at equal intervals, andthe limiting grooves are formed in the surface of the right side of the base plate at equal intervals; by arranging a rotating shaft, a turnout beam and an electric push rod, when the electric push rod works, turnout beams can rotate with the rotating shaft as the center, the ends, away from the rotating shaft, of the turnout beams reach the corresponding positions and are in butt joint with the corresponding track beams, one set of turnout beams can be in butt joint with different track beams, the occupied area is small, when the turnout beams are used in a parking lot, the layout of the parking lot is compact, the occupied area is saved, and therefore engineering investment is saved.
