ABSTRACT OF THE DISCLOSURE A novel controlled descent device is disclosed which not only aids in the ascent of a human being from a lower elevation to all upper elevation but also provides for the safe descent of a human being from the upper level to the lower level. The apparatus comprises a round cable, a counterweight, a controlled descent pulley having a ratchet and pawl brake system and a conventional pulley; all operating conjunctly dependently on the position and situation of the human being. The controlled descent pulley and conventional pulley are held in a plate structure which is secured to the upper elevation. The counterweight is raised and lowered from the upper elevation to the lower elevation and vice-versa by means of a guy wire which is anchored and held in relatively taught position between said upper elevation and said lower elevation.
