La hist\u00f2ria de l’ascensor no \u00e9s moderna, tot i que com a tal puguem considerar-lo un aparell recent, podem trobar sistemes similars que han precedit l’ascensor que avui coneixem.<\/p>\n

Quin \u00e9s l’ascensor m\u00e9s antic del m\u00f3n?<\/h2>\n

Com a tal, considerar\u00edem el m\u00e9s vell el comentat al post qui invento l’ascensor?<\/a> Per\u00f2 si anem m\u00e9s enll\u00e0 en el passat podem afirmar que l’ascensor t\u00e9 els seus comen\u00e7aments a l’Edat Antiga, molt abans de Crist. Els egipcis, els grecs, els mesopotamics, els xinesos i els romans ja utilitzaven un sistema de m\u00e0quines simples<\/strong>, com politges<\/strong>, cordes, rodes<\/strong> i plans<\/strong> inclinats<\/strong> per satisfer les seves necessitats arquitect\u00f2niques.<\/p>\n

Sistemes antecessors a l’ ascensor<\/h3>\n

Una de les teories de construcci\u00f3 de les Pir\u00e0mides sost\u00e9 que els egipcis van emprar a bous que tiraven dels blocs pel mig uns plans inclinats i subjectes per unes corretges de cuir i, en ocasions, ajudats per esclaus que tamb\u00e9 havien de tirar dels blocs.<\/p>\n

Altres sistemes, que podem veure en les imatges inferiors amb claredat s\u00f3n la roda t\u00edpica de Mesopot\u00e0mia<\/strong> i l’aparell Shadoof<\/strong>, una m\u00e0quina accionada per palanca per treure l’aigua del riu i regar els cultius, utilitzada tant pels egipcis com mesopot\u00e0mics.<\/p>\n

\n

\nTanmateix \u00e9s a
\n Arqu\u00edmedes <\/strong>
\n<\/a>a qui se li atribueix l’invent del primer elevador o ascensor, i aquest es podria dir que \u00e9s el sistema m\u00e9s semblant i antecessor de l’actual ascensor modern. En realitat s’utilitzava simplement per extreure aigua o productes de la terra de llocs inaccessibles i per regar els camps de collita. Com a curiositat afegir que es creu que aquest principi tamb\u00e9 va ser emprat per regar els jardins de Babil\u00f2nia.<\/p>\n

Cargol d’ Arqu\u00edmedes<\/strong><\/h3>\n

Es tracta d’ un aparell gravim\u00e8tric en forma d’ h\u00e8lix ideat per l’ any III a. C. pel matem\u00e0tic Arqu\u00edmedes. Denominat \u00abcargol<\/strong>\u00bb o \u00abcargol sense final\u00bb es compon d’una pe\u00e7a que gira en un tub allargat i buit, col\u00b7locat sobre un pla amb inclinaci\u00f3, i amb el qual el l\u00edquid ubicat m\u00e9s avall del mateix es pot extreure amb el simple moviment del seu eix.<\/p>\n

En els seus inicis no es tractava d’un sistema perfecte ni molt menys. En primer lloc si l’ aigua s’ extreia a molta al\u00e7ada es perdia la pressi\u00f3, per la qual cosa resultava molt m\u00e9s efectiva una extracci\u00f3 a baixes al\u00e7ades<\/strong>. En actualitat aix\u00f2 s’ha solucionat amb la tecnologia m\u00e9s avan\u00e7ada, com, per exemple, fent girar tamb\u00e9 el tub i no nom\u00e9s l’espiral, cosa que s’ha tradu\u00eft en una pot\u00e8ncia molt m\u00e9s gran, sobretot en aig\u00fces residuals.<\/p>\n

D’ altra banda cal comentar que el cargol d’ Arqu\u00edmedes no nom\u00e9s \u00e9s capa\u00e7 de succionar i transportar aigua, sin\u00f3 qualsevol altre objecte d’ acord amb la seva for\u00e7a de treball.<\/p>\n","protected":false},"excerpt":{"rendered":"
