Har'a batho ba sebelisang mofuta ofe kapa ofe oa lisebelisoa tsa indasteri,notlela/tagout (LOTO)ha se ntho e ncha.Ntle le haeba motlakase o khaotsoe, ha ho motho ea itetang sefuba ho etsa mofuta ofe kapa ofe oa ho lokisa kapa ho leka ho lokisa mochine kapa tsamaiso.Sena ke tlhokahalo feela ea kelello e tloaelehileng le Tsamaiso ea Ts'ireletso ea Mosebetsing le Bophelo bo Botle (OSHA).

Pele o etsa mesebetsi ea ho lokisa kapa ea ho lokisa, ho bonolo ho tlosa mochine ho tloha mohloling oa matla a oona-hangata ka ho tima mochine oa potoloho-le ho notlela lemati la phanele ea potoloho.Ho kenya leibole e khethollang litsebi tsa tlhokomelo ka mabitso le hona ke taba e bonolo.

Haeba motlakase o ke ke oa notleloa, ho ka sebelisoa leibole feela.Boemong bofe kapa bofe, ho sa tsotellehe hore na ho notletsoe kapa ho se na senotlolo, leibole e bontša hore tlhokomelo e ntse e tsoela pele 'me sesebelisoa ha se na matla.

Leha ho le joalo, sena ha se pheletso ea lotho.Sepheo ka kakaretso ha se feela ho hakolla mohloli oa matla.Sepheo ke ho sebelisa kapa ho lokolla matla ohle a kotsi-ka mantsoe a OSHA, ho laola matla a kotsi.

Sakha e tloaelehileng e tšoantšetsa likotsi tse peli tsa nakoana.Ka mor'a hore sesepa se tingoe, lehare la saw le tla tsoela pele ho matha ka metsotsoana e seng mekae, 'me le tla ema feela ha lebelo le bolokiloeng ka koloing le felile.Lehare le tla lula le chesa ka metsotso e seng mekae ho fihlela mocheso o fela.

Feela joaloka lisakha tsa polokelo ea mechine le matla a mocheso, mosebetsi oa ho tsamaisa mechine ea indasteri (motlakase, hydraulic le pneumatic) hangata o ka boloka matla ka nako e telele. Potoloho, matla a ka bolokoa nako e telele e makatsang.

Mechini e fapaneng ea indasteri e hloka ho sebelisa matla a mangata.AISI 1010 e tloaelehileng ea tšepe e khona ho mamella matla a ho kobeha a fihlang ho 45,000 PSI, kahoo mechini e kang mariki a ho hatella, litebele, litebele le liphaephe tse kobehang li tlameha ho fetisa matla ka lithane tsa lithane.Haeba potoloho e matlafatsa tsamaiso ea pompo ea hydraulic e koetsoe 'me e khaotsoe, karolo ea hydraulic ea tsamaiso e ntse e ka khona ho fana ka 45,000 PSI.Mechineng e sebelisang hlobo kapa li-blades, sena se lekane ho pshatla kapa ho khaola maoto le matsoho.

Lori ea liemere e koetsoeng e nang le bakete moeeng e kotsi joalo ka teraka e sa koaloang.Bula valve e fosahetseng mme matla a khoheli a tla nka sebaka.Ka ho tšoanang, tsamaiso ea moea e ka boloka matla a mangata ha e tingoa.Pipe bender ea boholo bo mahareng e ka monya ho fihlela ho li-ampere tse 150 tsa hona joale.Ka tlase ho 0.040 amps, pelo e ka emisa ho otla.

Ho lokolla ka mokhoa o sireletsehileng kapa ho fokotsa matla ke mohato oa bohlokoa ka mor'a ho tima matla le LOTO.Ho lokolloa ho sireletsehileng kapa ho sebelisoa ha matla a kotsi ho hloka kutloisiso ea melao-motheo ea tsamaiso le lintlha tsa mochine o hlokang ho hlokomeloa kapa ho lokisoa.

Ho na le mefuta e 'meli ea litsamaiso tsa hydraulic: loop e bulehileng le loop e koetsoeng.Sebakeng sa indasteri, mefuta e tloaelehileng ea lipompo ke likere, li-vanes le lipiston.Silinda ea sesebelisoa sa ho sebetsa e ka ba ntho e le 'ngoe kapa e habeli.Sistimi ea Hydraulic e ka ba le mofuta ofe kapa ofe oa mefuta e meraro ea li-valve-taolo ea tataiso, taolo ea phallo, le taolo ea khatello-e 'ngoe le e' ngoe ea mefuta ena e na le mefuta e mengata.Ho na le lintho tse ngata tseo u lokelang ho li ela hloko, kahoo hoa hlokahala ho utloisisa ka botlalo mofuta o mong le o mong oa karolo ho felisa likotsi tse amanang le matla.

Jay Robinson, mong'a le mopresidente oa RbSA Industrial, o itse: "Sehlahisoa sa hydraulic se ka tsamaisoa ke valve e koalang koung e felletseng.""Belofo ea solenoid e bula valve.Ha tsamaiso e ntse e sebetsa, mokelikeli oa hydraulic o phallela lisebelisoa ka khatello e phahameng le ho tanka ka khatello e tlaase, "o boletse joalo.."Haeba tsamaiso e hlahisa 2,000 PSI 'me matla a tima, solenoid e tla ea sebakeng se bohareng ebe e thibela likou tsohle.Oli ha e khone ho phalla 'me mochini oa emisa, empa sistimi e ka ba le PSI e fihlang ho 1,000 ka lehlakoreng le leng la valve."
