The invention relates to the technical field of cranes, in particular to a small-sized crane. The small-sized crane comprises a foundation bed, a base, a rotating shaft and a crane jib. A power mechanism comprises a shell, wherein a horizontal shaft is arranged inside the shell, and two ends of the horizontal shaft extend to the outside of the shell; a winding disc is arranged at one end, outsidethe shell, of the horizontal shaft, and a motor is connected to the other end, outside the shell, of the horizontal shaft; the motor is fixed to the shell; a worm wheel is arranged on the horizontal shaft inside the shell, a worm is further arranged inside the shell, and the worm is matched and connected with the worm wheel; and the end of the worm extends to the outside of the shell, and a rotating handle is arranged on the worm outside the shell. According to the small-sized crane, through reasonable structural design, the power of the crane can be freely converted between manpower and electricity, and the stability of the crane is high.
