To provide a power unit capable of performing slow stop adequately.SOLUTION: A power unit 1 comprises: a hydraulic pump 12 which supplies a hydraulic oil in an oil tank 11 to a hydraulic cylinder of a drive device 3; a motor 13 which drives the hydraulic pump 12; a counter 16 which counts cumulative rotation number of the motor 13; a storage part 17 which can previously store a scheduled count number CM corresponding to scheduled cumulative rotation number of the motor 13 until a load receiving stand 2 lowers from an ascending limit position and contacts a ground; and a control part 18 which controls the motor 13 so as to start slow stop of the load receiving stand 2 when the count number by the counter 16 has reached a specified value, when lifting the load receiving stand 2. The control part 18 stops counting by the counter 16 until ascending motion of the load receiving stand 2 starts if the count number by the counter 16 reaches the scheduled count number CM during lowering motion of the load receiving stand 2.SELECTED DRAWING: Figure 4
