Theem machinery yog tsim los ntawm ntau yam ntawm tus kheej. Raws li kev siv tshuab thev naus laus zis tau nce siab, nws tau dhau los ua tau - raws li cov yam ntxwv tshwj xeeb ntawm qhov chaw ua yeeb yam thiab ib puag ncig ntawm cov chaw xws li theatre thiab studios - txhawm rau siv lub cev uas twb muaj lawm los qhia thiab ua tiav cov qauv teeb pom kev zoo.
Stage machinery pom daim ntawv thov nyob rau hauv ntau qhov chaw, nrog rau qhov chaw ua yeeb yam xws li theatre thiab studios. Hais txog qhov chaw nyob ib puag ncig ntawm cov chaw xws li: nws yog ib qho tseem ceeb uas yuav tsum tau ua kom tiav qhov chaw soj ntsuam - ntsuas thiab sau ntawv, lossis lwm yam tau txais, cov phiaj xwm hauv pem teb thiab ntoo khaub lig- ntu kos duab ntawm qhov chaw ua haujlwm. Qhov no suav nrog kev sau cov ntaub ntawv ntawm qhov siab thiab dav ntawm proscenium koov, qhov tob ntawm theem, thiab cov nplai tshwj xeeb siv hauv cov duab kos. Hais txog cov khoom siv raws li txoj cai: nws yog ib qho tsim nyog yuav tsum tau sau cov khoom kom muaj nuj nqis, qhov ntev, qhov sib txawv, qhov sib npaug ntawm tus lej, thiab qhov tseeb qhov chaw ntawm tag nrho cov rigging battens thiab theem machinery Cheebtsam. Hais txog hluav taws xob load yuav tsum tau rau theem machinery: ib tug yuav tsum xyuas kom meej lub rated load peev xwm ntawm lub ntsiab lub hwj chim kab nrog rau cov rated load peev xwm ntawm tus kheej ceg circuits. Txoj kev kawm thiab kev xav ntawm cov ntawv sau ua lub hauv paus rau kev xaiv cov khoom siv teeb pom kev zoo thiab tsim cov tswv yim muaj tswv yim; Los ntawm cov txheej txheem no, ib tus tuaj yeem txheeb xyuas thiab rho tawm cov ntsiab lus nthuav dav uas cuam tshuam rau lub zeem muag muaj tswv yim, tom qab ua kom zoo dua thiab ua tiav lawv rau hauv kev sib koom ua ke. Lub hom phiaj yog txhawm rau txheeb xyuas tus neeg sawv cev ntawm tus cwj pwm zoo, kev txhim kho zaj dab neeg, kev tsis sib haum xeeb, thiab qhov chaw ib puag ncig tshwj xeeb xav tau los ntawm kev piav qhia. Cov tshuab theem ua kom yooj yim rau lub tswv yim thiab qhov tseeb ntawm qhov chaw xws li keeb kwm era, lub sijhawm ntawm hnub, lub caij, ib puag ncig tshwj xeeb, kev coj ntawm lub teeb ci, thiab xim palette. Cov txheej txheem no ua rau kev txiav txim siab ntawm qhov tsim nyog ua haujlwm zoo nkauj thiab cov txheej txheem nthuav tawm uas ua raws li kev tsim khoom. Nws suav nrog kev txiav txim siab seb lub teeb pom kev zoo twg tuaj yeem siv los tsim cov theem pom pom uas zoo sib haum xeeb nrog cov lus piav qhia zoo heev. Tsis tas li ntawd, theem tshuab ua lub luag haujlwm tseem ceeb hauv kev txhais cov ntsiab lus pom ntawm qhov chaw thiab ua kom yooj yim rau kev ua haujlwm ntawm cov khoom siv theem. Nws tso cai rau cov neeg sawv cev zoo nkauj ntawm kev hloov pauv hauv lub sijhawm thiab qhov chaw - suav nrog cov xwm txheej huab cua (xws li hnub sawv thiab hnub poob, twilight hloov mus rau hmo ntuj, hmo ntuj muab txoj hauv kev rau kaj ntug, hloov raws caij nyoog, thiab hnub qub moonlit hmo) nrog rau kev hloov ntawm qhov chaw thiab thaj chaw. Thaum kawg, nws pab txhawb kev sib cuam tshuam thiab kev hloov pauv ntawm ntau qhov sib txawv ntawm qhov ntev - suav nrog thaj chaw thaj chaw, qhov chaw puas siab puas ntsws, qhov chaw zoo nkauj, qhov chaw virtual, thiab kev hloov pauv kev sib raug zoo ntawm cov ntsiab lus tshwj xeeb thiab tag nrho spatial muaj pes tsawg leeg.
