The crawling ladder comprises a cover plate which is arranged at the top of a stand column, wherein a first hoop is arranged along the side wall of the stand column; the cover plate is further provided with a lifting hook which is connected with the first hoop and is used for fixing the first hoop; and the first hoop is connected with a ladder rod for a worker to climb to the top of the stand column. The cover plate comprises at least three rod pieces which are connected end to end to form a sealed plane pattern and are fixed at the top of the stand column. The front and tail ends of any rod piece are located outside the range of the top of the stand column; and the lifting hook is arranged at the mutually-connected connection part of the two rod pieces. The first hoop is located at the position close to the top of the stand column; and a second hoop, which is connected with the ladder rod, is further arranged at the position close to the bottom of the stand column and along the side wall of the stand column. The first hoop and the second hoop are separately arranged, and are connected by a bolt to form a whole body and are wound on the side wall of the stand column.
