Imikhiqizo
U-Andy Telescopic Jib Crane
I-Andy Telescopic Crane enomsebenzi ka-Andy crane ingukhreni wekhamera yokuqala futhi okuwukuphela kwayo yekhamera ye-telescopic emhlabeni ekukhiqizweni ekwazi ukunyakaza okuma mpo kwe-telescopic enebanga lokutsheka ukusuka ku--25 degrees ukuya kuma-degree angama-90 eqiniso. IJoke eligoqekayo eliyingqayizivele liyivumela ukuthi iguquke isuke kukhreni ojwayelekile wetelescopic onobubanzi be-engeli etshekile iye ku-Andy Crane enobubanzi obuncishisiwe bokutsheka obuya phansi namandla aqondile.
Lawa makhono andayo avumela i-crane ukuthi idubule amashothi ayengenakwenzeka ngaphambili ezindaweni eziqinile, izitebhisi eziwumngcingo njll. Ijoka eligoqekayo livumela opharetha ukunyakaza okushelelayo kokutsheka kusuka ku--25 kuya ku-90 degrees kanye nokunyakaza okugcwele kwepani okungaphazamiseki.
I-Andy Crane isuselwe ku-Andy Standard yethu evamile: ikhamera yekhamera ye-telescopic engasindi futhi esheshayo enezigaba ezimbili. Ubukhulu bayo obuncane kanye nokwakhiwa okuqinile kuyenza i-crane esebenza ngezindlela ezihlukahlukene ekwazi ukugxunyekwa ezindaweni eziningi okuhlanganisa nodoli omusha we-Andy scissor, unodoli wekhamera osebenza kanzima, imoto yekhamera esebenza ngogesi njll. I-crane ihlanganisa ingxenye eyisiphambano enoveli engunxantathu enesistimu yesitimela yomhlahlandlela enamaphuzu amathathu, kanye nezingxenyekazi ze-aluminium ezikhishwayo ezikwazi ukumelana nengcindezi ephezulu nezingxenye zayo ze-aluminium ezikwazi ukucindezelwa kakhulu. ukushaqeka ngenkathi uhamba emotweni. Inganikwa amandla ngephakethe lebhethri elijwayelekile elingu-48V noma i-110-240V AC (kusetshenziswa iyunithi yokuphakela amandla efakiwe ye-AC/DC).
I-Andy crane iphinde ibe nekhanda elisha elilevelini elinamandla okugoba ngaphezulu nangaphansi kwe-slung, izinkinobho zokususa izinga elilungisekayo kanye nesengezo se-Gyroscopic Leveling [GLA]. I-Andy scissor dolly entsha yokuzikhethela enezingalo ezigoqekayo ivumela ukushintsha ububanzi bamasistimu ethrekhi ahlukene. Ekucushweni kwayo okuhlangene kakhulu ivumela ukuhambisa ukhreyini ngezicabha zamahhovisi amancane (0,8m).
Yini iJib?
Ku-cinematography, i-jib iyithuluzi le-boom elinekhamera ngakolunye uhlangothi kanye ne-counterweight nezilawuli zekhamera ngakolunye. Isebenza njengesaha eline-fulcrum phakathi nendawo. I-jib iwusizo ekutholeni amashothi aphezulu, noma amashothi adinga ukuhamba ibanga elide; ngokuvundlile noma mpo, ngaphandle kwezindleko nezindaba zokuphepha zokubeka u-opharetha wekhamera kukhreni. Ikhamera ilawulwa isilawuli kude esinekhebula ekugcineni, kanti ngakolunye i-electro mechanic pan/enyakazayo ephendula kakhulu (ikhanda elishisayo) - evumela amapani abushelelezi nokutshekisa.
Kuthatha isikhathi esingakanani ukusetha i-Andy Telescopic Jib?
Sizohlala sikucela ukuthi uvumele ihora elilodwa ukuze i-Telescopic Jib imiswe endaweni eyisicaba, nokho i-Telescopic Jib ivamise ukulungela ukusebenza emizuzwini engamashumi amane nanhlanu. Uma indawo iyingozi kakhulu, isikhathi esiningi siyadingeka. Kuphinde kuthathe cishe imizuzu eyishumi ukulingana nokulinganisela ikhamera ku-hothead.
