Rope Ascenders & Descenders

For rope access climbing you normally use both together. The handled ascender does the pulling and takes most of the load, while the chest ascender keeps you upright on the rope and holds the progress you make between strokes. A foot ascender is an optional third device that takes the strain out of long climbs. For short climbs or hauling gear, a single handled ascender is often enough. Note that handed models come in left and right versions and are not interchangeable.

A mechanical ascender is a manual device that grips the rope with a sprung toothed cam. It slides freely up the rope and locks solid when loaded. Mechanical refers to the cam mechanism, not a motor, so handled, chest and foot ascenders are all mechanical ascenders. They need no charging, no fuel and no servicing beyond routine inspection, which is why they remain the standard choice for most rope access work.

A powered ascender earns its price when the same climb is repeated day after day, when equipment has to be raised along with the climber, or when a rescue plan may call for lifting a casualty rather than lowering them. The battery or petrol drive does the climbing for you, which saves serious time and fatigue on tall structures. For occasional single climbs, a manual setup does the same job at a fraction of the cost.
