Which devices are commonly used for descent in rope access?

Descenders such as figure-eight or assisted braking devices are specifically designed for controlled descent in rope access situations. These devices allow technicians to manage their speed during descent, providing both safety and control. The figure-eight descender, for instance, creates friction when the rope runs through it, allowing the user to control their rate of descent efficiently. Assisted braking devices are engineered to provide additional safety by automatically slowing down a descent if the technician loses control, making them reliable choices for high-altitude work.

Other devices like helicopters or lifts are not used for descent within the context of rope access, as they do not fall under the category of equipment specifically designed for maneuvering on ropes. Autonomous drones, while useful in various applications, do not have a role in descending along a rope. Hand-held winches are typically used for lifting and not for controlled descent, which further underscores why they do not meet the specific needs outlined in this question.
