Amandla e-Jimmy Jib "ukufinyelela" kwengalo ye-crane okuba isici esibalulekile ekudaleni izingoma ezithokozisayo neziguqukayo kanye nokuvumela opharetha ukuthi aphakamise ikhamera ngaphezu kwezintambo zamandla ezisithekile noma abahamba bekhonsathi abagqwayizayo - ngaleyo ndlela kuvumela ukucaca. , isibhamu esiphezulu uma kudingeka.
Ingashona phansi kangakanani?
Nge-"Triangle" uJimmy Jib asethwe ekucushweni "ngaphansi kwe-slung", ikhamera ingenziwa ukuthi iphumule cishe ngokuqondile ukusuka phansi - okwenza ubude obuncane belensi bube ngamasentimitha angu-20 (amayintshi angu-8).Yiqiniso, uma uzimisele ukumba umgodi, nqamula ingxenye yesethi noma udubule endaweni yesikhulumi lokhu kuphakama kwelensi encane kungancishiswa.

Sihlala siphakamisa kufika kumahora angu-2 ukuze silungise i-Jimmy Jib.Lokhu ngokusobala kuzoncika ekusondeleni kwemoto kanye nendawo yokusebenza.
I-Jimmy Jib ingahanjiswa kalula kanjani phakathi kwezindawo?
Ngemva kokwakhiwa kokuqala, i-Jimmy Jib ingaphinde ibekwe kabusha kalula kulo lonke izinga kanye nomhlabathi ocacile kusisekelo sayo esinamasondo.Uma indawo ingenayo indawo esezingeni, ukwakhiwa kabusha kungathatha ukusuka ku-30mins+, kuye ngebanga nezimo.
Iyiphi indawo yokusebenza edingekayo ye-Jimmy Jib?
Ngokuya ngosayizi we-jib kanye nenani le-counterweight elidingekayo, isikhala esidingekayo ukuze wenze i-jib "yenze into yayo" ingahluka.Sicela ubheke imidwebo engezansi ukuze uthole izilinganiso kuye ngokusetha okuthile kwe-Jimmy Jib.
I-jib ivamise ukwakhelwa esizindeni sayo okuthi yona ifakwe emasondweni enjoloba amakhulu (off road) noma amasondo e-studio crab dolly.Ingxenye yephoyinti le-fulcrum inweba ngobude obuhlukahlukene kuye ngokufinyelela kwengalo oyisebenzisayo, kufika kumkhawulo wamamitha angu-13.2 (amafidi angu-40).Ingxenye engemuva inweba ukusuka ku-fulcrum ngezikhawu zamasentimitha angamashumi ayisishiyagalolunye (3 amafidi) kufika kumkhawulo wamamitha amathathu (amafidi angu-9) - kodwa igumbi nalo liyadingeka ukuze isisebenzisi ame ngemuva futhi alawule ingalo ye-boom.
Isebenza kanjani inhloko yesilawuli kude?
Ikhanda elikude (noma ikhanda elishisayo) lisebenza ngephaneli yokulawula induku yokudlala.Izilawuli zixhunywe ngentambo eya ekhanda, equkethe ama-servo motors kagesi alawulwa kahle kanye namagiya.Lokhu kulungiselelwe ukuvumela u-opharetha ukuthi aphenye, atshekise futhi "eslip ring" eyengeziwe, roll.Le hothead ithule, ivumela ukusebenza ngempumelelo ezindaweni zokukhiqiza ezizwelayo.
Kudingeka abantu abangaki ukusebenzisa i-Jimmy Jib?
Ngokuvamile, opharetha ababili bayadingeka ukuze kusebenze i-jib.Umuntu oyedwa "uyashwibeka" (unyakazisa) ingalo ye-boom ephikisanayo, kuyilapho omunye eqhuba ikhanda elishisayo.Sihlinzeka bonke opharetha / ochwepheshe abadingekayo ekusebenzeni kwe-Jimmy Jib.

Sizohlala sikucela ukuthi uvumele ihora elilodwa ukuze i-jib imiswe endaweni eyisicaba, nokho i-jib ngokuvamile ilungele ukusebenza emizuzwini engamashumi amane nanhlanu.Uma indawo iyingozi kakhulu, isikhathi esiningi siyadingeka.Kuphinde kuthathe cishe imizuzu eyishumi ukulingana nokulinganisela ikhamera ku-hothead.
Ingabe i-Jimmy Jib ingakwazi ukuthwala amakhamera angu-4k noma angu-6k Digital Cinema?
Yebo, sivame ukudubula namanye amakhamera e-monster kuhlanganise nawo wonke ama-bolt-on's.Ngokuya ngosayizi we-Jimmy Jib eyakhiwe, umthwalo ophephile wokusebenza uyahlukahluka kusuka ku-27.5kg kuya ku-11.3kg.Sishayele futhi usitshele ukuthi iyiphi ikhamera ofuna ukushutha ngayo.
Imaphi amakhamera owasebenzisayo ne-Jimmy Jib?
Siyabuthanda ubuchwepheshe obusha futhi sijabule ukusebenzisa amakhamera amasha njengoba ekhishwa njalo ngemva kwezinyanga ezimbalwa.Endaweni sivame ukushutha ngamakhamera we-Digital Cinema afana ne-Sony FS7, i-Arri Alexa, i-Arri Amira kanye nekhamera ye-RED noma i-Phantom High-Speed njalo.Futhi sisacelwa ukuthi sithwebule nge-Sony PMW-200 esungulwe kahle noma i-PDW-F800.Mayelana nokushuthwa kweSitudiyo noma kwe-OB, sisebenza ngenjabulo nganoma yini isikhungo esifuna ukusihlinzeka.
Amakhamera wefilimu
Uma i-Focus Puller idingeka ukuze isebenzise isilawuli selensi sokufocus/zoom/iris, uzodinga ukuthi uhlole nabo uma bekhetha iyunithi yokulawula engenantambo noma enezintambo eziqinile.Okukhethwa kukho okunezintambo eziqinile, ikhebuli engamamitha angu-10 (amafidi angu-30) iyisidingo esincane - kanye nokuthepha ividiyo yekhamera.
Indawo Yesitudiyo
I-Jimmy Jib ivamise ukusetshenziswa ezimeni zesitudiyo futhi ingahlinzekwa kumasondo e-studio crab dolly eyakhelwe phezu kwe-HP pedestal eguquliwe, eyakhelwe phezu kwethrekhi eqinile, noma egxunyekwe kunodoli ojwayelekile.
Ingabe i-Jimmy Jib idinga Uchwepheshe noma Umsizi?
Zonke izingcaphuno zifaka u-Jimmy Jib Technician njengomuntu wesibili no-Jimmy Jib.Lokhu kuvumela ukudubula okusheshayo nangezinye izikhathi okushukumisayo nakakhulu kanye nokunciphisa izingozi ezingaba khona ezirekhodwe ku-Jimmy Jib Risk Assessment futhi njengoba kuchazwe Isiphathimandla Sezempilo Nokuphepha.*I-40ft Jimmy Jib idinga ochwepheshe ababili.
