About: Bachmann knot

An Entity of Type: WikicatClimbingKnots, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

The Bachmann hitch (sometimes misspelled 'Bachman') is a friction hitch, named after the Austrian alpinist . It is useful when the friction hitch needs to be reset quickly or often or made to be self-tending as in crevasse and self-rescue. (See Prusik knot) However, with a non-locking carabiner it is safer to use the knot with the carabiner gate opening facing down (opposite to what is shown in the picture). This decreases the risk of self-unclipping: at maximum, one twist goes off. Otherwise, the whole knot may fail.

  • The Bachmann hitch (sometimes misspelled 'Bachman') is a friction hitch, named after the Austrian alpinist . It is useful when the friction hitch needs to be reset quickly or often or made to be self-tending as in crevasse and self-rescue. (See Prusik knot) The Bachmann hitch requires the use of a carabiner. It does not matter if the carabiner is locking or not. Most importantly, the carabiner must be of round cross section for friction. Grabbing hold of the carabiner will release the friction and allow the hitch to slide freely and thus be moved appropriately. To remove the Bachmann hitch, just unclip the top loop, hold on to the carabiner and pull the cord free. This knot is frequently tied using a sling made from 1" tubular webbing. In this case wrap the webbing 3 times around the rope (this means the carabiner gate must be opened 3 times in the tying of the knot) for normal (dry) applications. There are a limited number of applications that involve repeated shock loads to the knot and in these 4 wraps are usually sufficient. However, with a non-locking carabiner it is safer to use the knot with the carabiner gate opening facing down (opposite to what is shown in the picture). This decreases the risk of self-unclipping: at maximum, one twist goes off. Otherwise, the whole knot may fail. It is important for safety reasons to mention that the rope used for the friction hitch should be smaller in diameter than the tension rope. This allows for movement when resetting the hitch position but when a large load is applied to the friction hitch, the hitch locks on to the tension rope. If two ropes of the same diameter are used for the friction hitch and tension rope, the hitch may move freely like a slip knot (lasso or noose) and not lock into place. When encircling any cylindrical object, most ropes can only be tightened to a diameter slightly greater than the ropes own diameter(USMC Assault Climber Course). (en)
  • Il nodo bachmann è un nodo autobloccante efficace per creare un sistema di salita o di discesa lungo la corda da arrampicata. Questo tipo di nodo si blocca automaticamente sulla corda quando viene caricato di un peso e si libera quando il peso viene tolto. Questo tipo di nodo in particolare viene eseguito intorno ad un moschettone e questo fa in modo che la corda scorra liberamente nella direzione opposta al carico. (it)
  • Węzeł Bachmanna – jeden z węzłów stosowanych we wspinaczce. Węzeł stosowany podobnie jak prusik – czyli m.in. do autoasekuracji podczas zjazdu na linie. (pl)
  • Nó autoblocante ou nó Bachmann é um tipo de nó blocante de grande utilidade para sistemas de segurança, desvio ou tração. Possui a particularidade de prender tão mais quanto maior for a força aplicada em sua alça. Uma vez aliviada a força, pode-se movêlo facilmente ao longo da corda. Usado por montanhistas em subidas ou descidas verticais. Uma vez feito o nó pode-se corrê-lo pela corda principal, bastando para firmá-lo que se aplique um peso sobre ele. Desta forma, é utilizado como auto-segurança em escaladas em paredes quando já se tem um cabo livre instalado ao longo dela. Mesma utilização do Nó marchand, Nó prussik ou do Nó Bachmann. (pt)
