The invention discloses a self-locking type slide trolley. The self-locking type slide trolley comprises a slide trolley body and a hook connected with the slide trolley body. The slide trolley body comprises side plates. A pulley shaft is arranged between the centers of the side plates. Pulleys are arranged on the pulley shaft. A protrusion part is arranged on the outer side of the connection position of the hook columnar part and the hook-shaped part. A safety buckle is hinged to the protrusion part. The lower end of the slide trolley body is provided with a derailing-proof device through which the pulleys of the slide trolley body are prevented from slipping off from a slide rope. By means of the self-locking type slide trolley, the technical problem that the hook is liable to slip off is solved. In addition, the lower end of the slide trolley body is provided with a derailing-proof device through which the pulleys of the slide trolley body are prevented from slipping off from a slide rope, and the slide rope penetrates through a limiting gear, so that even if the slide rope slides drastically, the phenomenon of derailing is avoided due to limiting of the limiting gear. Therefore, the safe and reliable operation of the slide trolley body is ensured fundamentally.
