The anchor point does not prevent a fall, but prevents the belayer from being pulled upwards during a fall. [4] This is normally not used when lead belaying. [5] To set up this anchor the belayer should place a piece of directional protection (i.e., a nut or cam) into a crack below their body, or tie themselves by the belay loop to a rock or tree.
In the anchor escapement the swing of the pendulum pushes the escape wheel backward during part of its cycle. This "recoil" disturbs the motion of the pendulum, causing inaccuracy, and reverses the direction of the gear train, causing backlash and introducing high loads into the system, leading to friction and wear.
Then the tooth slides off the end of the pallet, beginning the cycle again. Neither the anchor escapement nor the deadbeat form, below, are self-starting. The pendulum must be given a swing to get them going. Pendulum and anchor escapement. (a) pendulum rod (b) pendulum bob (c) rate adjustment nut (d) suspension spring (e) crutch (f) fork (g ...
Uses include creating friction prusik knots for ascending or gripping fixed climbing ropes, usually using thinner approximately 5 to 6 mm (0.20 to 0.24 in) cord, or for attaching to, and equalizing forces across, multiple fixed anchors points, [15] such as when setting up abseil or belay anchors on multi-pitch climbing routes, usually using ...
In rock climbing, an anchor can be any device or method for attaching a climber, rope, or load to a climbing surface—typically rock, ice, steep dirt, or a building—either permanently or temporarily. The intention of an anchor is case-specific but is usually for fall protection, primarily fall arrest and fall restraint.
Roller – Davit slides down a track, bringing the davit to the embarkation deck. Single pivot – One pivot point where the lifeboat is moved over the side of the craft. Multi-pivot – Common on promenade decks of cruise ships. Useful where space is limited. Free fall – Lifeboat slides right off vessel. Lifeboat must be an enclosed type.
The fastener is an anchor, an expandable sleeve that slides into a hole drilled into the wall. A lip wider than the hole prevents it from falling behind the wall, and often features such as cleats/spikes prevent it from rotating when being compressed.
Lead climbing (or leading) is a technique in rock climbing where the 'lead climber' clips their rope to the climbing protection as they ascend a pitch of the climbing route, while their 'second' (or 'belayer') remains at the base of the route belaying the rope to protect the 'lead climber' in the event that they fall.
