Abstract: A safety-featured ladder, including taut rope wrapped over top of the top rung and under bottom of the bottom rung and fixedly connected to the ladder when downward force is applied to the rope in front of the ladder. In a first embodiment, a sleeve including a pulley subsystem is attached to a body harness worn by a climber and can move or slide along the rope only when climbing up ladder. In a second embodiment, a sleeve including a different pulley subsystem including a centrifugal brake is attached to a body harness worn by a climber and can move or slide along the rope when climbing up or climbing down. However, if the climber loses footing and starts to fall the sleeve grabs the rope, and/or the rope grabs the sleeve, which prevents the climber from falling more than a few inches and from injury. Hooks at top of the ladder can hook around transverse cables atop poles.
