The invention relates to a crank-arm-type aerial work platform flexible in work range. The crank-arm-type aerial work platform comprises a traveling chassis, a driving device and a lifting device. The lifting device comprises a lifting arm assembly and a work platform body. The lifting arm assembly comprises a foldable arm assembly. The foldable arm assembly comprises a first connecting piece, a second connecting piece, a third connecting piece, a first connecting arm, a second connecting arm, a third connecting arm, a first balance rod, a second balance rod and lifting air cylinders. The work platform body comprises a swing adjusting piece and an operating table. The swing adjusting piece comprises an adjusting piece body, a horizontal-rotating-oil-cylinder outer body and a horizontal-rotating-oil-cylinder inner core. A horizontal sensor is further arranged on the work platform body. It can be guaranteed that the work platform is kept balanced all the time in the lifting process, the function that the work platform aerially and horizontally swings to be adjusted is also achieved, and the overall use is more flexible; and in addition, the whole driving device of the work platform can rotate, the work platform is driven to rotate accordingly, and the work radius is increased.
