Sit-stand systems (also known as frog rig) - one ascender is at chest level attached to the sit harness, and a second is held in the hand with a long loop of rope for the feet. Movement up the rope is by repeated moving of the foot loop ascender up the rope, pushing up with both feet together, and sitting, supported by the chest ascender.
An ascender is a device (usually mechanical) used for directly ascending, or for facilitating protection, with a fixed rope when climbing on steep mountain terrain. A form introduced in the 1950s became so popular it began the term "Jumar" for the device, and the verb "to jumar" to describe its use in ascending.
This device utilizes a large surface area in contact with a climbing rope to provide sufficient friction along with the proper technique to be used as a belay device or for rappelling. A figure 8 (sometimes just referred to as an 8) is used in conjunction with a climbing harness and locking carabiner to control a belayed climber's descent, or ...
Many different techniques (free climbing, self-belayed climbing with a doubled-rope technique, single-rope technique, and lead climbing) are used to climb trees depending on the climber's purpose for the climb and personal preference. Free climbing is performed without protective gear, and as such is the oldest method of climbing.
In climbing and mountaineering, a fixed-rope (or fixed-line) is the practice of installing networks of in-situ anchored static climbing ropes on climbing routes to assist any following climbers (and porters) to ascend more rapidly—and with less effort—by using mechanical aid devices called ascenders.
The rock-climbing equipment needed varies materially depending on the type of rock climbing being undertaken. Starting from the least equipment-intensive type of climbing, the general equipment needs are as follows: [1] Free solo climbing, and its deep-water soloing variant, require the least equipment as no climbing protection or ropes are used.
A friction hitch is a kind of knot used to attach one rope to another in a way that is easily adjusted. These knots are commonly used in climbing as part of single-rope technique, doubled-rope technique and as "ratchets" to capture progress on a moving rope, most typically in a mechanical advantage system such as a Z-drag.
Early versions of the cam systems used a Gibbs-style type 1 ascender placed in an inverted position attached to a soloer's sit harness opposite to the manufacturer's intended use. The combination of a climber's body position in a fall and friction between the ascender frame and the rope provides the activating leverage for the cam to grab the rope.
