The invention discloses a self-lubricating portal crane. The self-lubricating portal crane comprises a rotary drum, wherein rotary drum fixing blocks are rotatably connected to the left end and the right end of the rotary drum, a lifting hook line is wound around the outer circle surface of the rotary drum, lifting hook fixing blocks are arranged at the lower side of the rotary drum, and lifting hooks are fixedly connected to the lower ends of the lifting hook fixing blocks; and the upper ends of the lifting hook fixing blocks are fixedly connected with a lifting hook line, a switching power mechanism is arranged in the rotary drum fixing block at the left side, and a rotary shaft is rotatably connected to the end, away from the rotary drum, of the rotary drum fixing block. According to the invention, dust on the surface of the machine can be removed in a running process, and the running state of the machine is prevented from being affected by particulate matter such as dust; and meanwhile, evaporation of water on the surface of the machine can be accelerated after raining to prevent rainwater from staying for a long time to corrode the surface of the machine to affect the working state, lubricating liquid can be automatically supplemented in the running process, and the situation that the service life is affected by abrasion of the machine due to too little lubricating liquid is prevented.
