The invention discloses a pull rope lifting safety maintenance ladder truck which comprises a bottom frame, ladder wheels walking along steel rails and rail clamping devices for locking the bottom frame on the steel rails are arranged on the outer side of the bottom frame, mounting pipes for fixing a ladder body structure in an inserting and pulling mode are arranged at the upper end of the bottom frame, and the ladder body structure is a vertically-lifting multi-stage ladder body structure. And a working platform for maintenance personnel to work is arranged at the upper part of the ladder body structure. According to the ladder truck structure, the chassis, the ladder, the supporting rods and the like are rapidly combined for connection, and field operation of maintainers is facilitated. The ladder body part adopts a rope telescopic mode, so that after each part is folded, the size is minimum, and the ladder can be easily carried. The differential rope is mounted at the top of the ladder truck, so that the safety of workers is guaranteed during the time when the workers get on the ladder truck and get off the ladder truck and during operation. The rail clamping device is of a rotary drawing type structure and can be conveniently and rapidly clamped to the outer side of a steel rail, and the rollover prevention function of the ladder truck is achieved.
