A crankshaft-type aerial working platform electrocar comprises a platform car chassis, a rotary base installed in the middle of the upper side of the platform car chassis, a lifting crankshaft installed on the rotary base and a working platform installed at the lifting end of the lifting crankshaft. The platform car chassis comprises a main frame, a front axle and a rear axle, wherein the front axle and the rear axle are connected to the front end and the rear end of the main frame, and the two ends of the front axle and the two ends of the rear axle are provided with wheels respectively. Therotary base is connected with the platform car chassis through a rotary flange plate. The lifting crankshaft comprises a dual-parallelogram lifting assembly, a leveling crankshaft assembly connected with the dual-parallelogram lifting assembly and a parallelogram lifting arm connected with the leveling crankshaft assembly. The working platform and the parallelogram lifting arm are vertically hinged so that the working platform can swing and rotate left and right relative to the lifting crankshaft.
