The invention provides a small-sized autocrane which comprises an operating valve, a bracket, a loading limit rod, a lower knuckle arm, a foldable hydraulic cylinder, an upper knuckle arm, a telescopic hydraulic cylinder, a telescopic arm, a lifting hook, a middle arm, a lifting hydraulic cylinder, a swing mechanism, a rack and a supporting leg, wherein the bracket is arranged at the top of the operating valve; one end of the bracket is in close contact with the lifting hydraulic cylinder; the loading limit rod is arranged on one side of the lifting hydraulic cylinder, and is arranged at one end of the lower knuckle arm; the foldable hydraulic cylinder is arranged on one side of the lower knuckle arm; the foldable hydraulic cylinder is in close connection with the upper knuckle arm; the telescopic hydraulic cylinder is arranged on one side of the upper knuckle arm; the telescopic arm is fixedly connected with the tail end of the telescopic hydraulic cylinder; the lifting hook is arranged at one end of the telescopic arm. Pressure on the road surface by a vehicle below the autocrane is reduced, and a lifting arm does not need to be unloaded from the vehicle to be independently transported; compared with the conventional large-size autocrane, the labor is saved, the transportation cost is reduced, and the work efficiency is improved.
