The butterfly loop, also known as lineman's loop, butterfly knot, alpine butterfly knot and lineman's rider, is a knot used to form a fixed loop in the middle of a rope.Tied in the bight, it can be made in a rope without access to either of the ends; this is a distinct advantage when working with long climbing ropes.
An artificial climbing anchor consisting of a hex and two cams, equalized with slings. A snow picket . Depending on the surface being climbed, there are many types of protection that can be used to construct an anchor, including natural protection such as boulders and trees, or artificial protection such as cams , nuts , bolts or pitons .
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 ...
A climber and a belayer using a climbing rope. A climbing rope is a rope that is used in climbing.It is a critical part of an extensive chain of protective equipment (which also includes climbing harnesses, anchors, belay devices, and carabiners) used by climbers to help prevent potentially fatal fall-related accidents.
Some climbers will use a single full-thickness climbing rope with a diameter of approximately 9 to 11 mm (0.35 to 0.43 in), and some will use double ropes, or "half-ropes", to reduce rope drag (e.g. one rope is clipped into any given anchor or protection point), which have a reduced thickness of approximately 8 to 9 mm (0.31 to 0.35 in) to ...
Ropes can be of unequal sizes. It is often used to tie both ends of the same rope together to form a circle. Triple fisherman's knot: Overhand bend (also known as European death knot, Euro death knot, EDK): The Overhand bend is a simple and fast way to join two ropes, notably for rappelling. Can be very useful in situations where speed is ...
Static ropes are designed to allow relatively little stretch, which is most useful for applications such as hauling and rappelling. Dynamic rope is used to belay climbers, and is designed to stretch under a heavy load to absorb the shock of a fallen climber. Dynamic ropes manufactured for climbing are tested by the UIAA. A test of "single ...
Australian rappel demonstrated at a dam in Norway Climber performing Australian rappel on Orlando Power Station cooling towers in Soweto, South Africa. Australian abseiling (also known as Australian rappelling, Rap Jumping, Angel Jumping or deepelling) is the process of descending a fixed rope in a standing position while facing the ground.
