The invention relates to the technical field of cranes, and discloses a self-powered telescopic mechanism and a crane.The self-powered telescopic mechanism comprises a telescopic mechanism body, a transmission mechanism and a generator, the telescopic mechanism body comprises a barrel and a telescopic rod, one end of the telescopic rod is movably arranged in the barrel, and the telescopic rod can stretch out and draw back relative to the barrel; the generator is fixedly connected with the barrel and comprises a stator and a rotor, the rotor can rotate relative to the stator, the power input end and the power output end of the transmission mechanism are connected with the telescopic rod and the rotor respectively, the telescopic rod moves to drive the rotor to rotate through the transmission mechanism so that the generator can generate electricity, and the generator and the telescopic mechanism are distributed in the radial direction of the telescopic mechanism. The self-powered telescopic mechanism can solve
