The present invention can be used not only for forestry but also for evacuating from the outer wall of a high-rise building to the roof in the event of a flood disaster because the rope can be climbed and descended only by leg strength. Multiple climbers can be attached to the book rope.

In the general view of the lobe climber, the left and right (9.9") of the pedal is not oriented, and the movable side is left. FIG. 1 is a bottom view (left side) and a top view A-A″ view (right side). A detailed view of the movable side box seen from the inside of the rail, the fixed side box is omitted because the structure is the same as the movable side except that it is fixed to the rail and the left and right are reversed. show).
