Corbett, Fire Engineering, Zvita 1991, peji 70.) Zvinofanira kutariswa kuti pombi huru inopihwa nepombi huru ine dhayamita isingasviki masendimita matanhatu uye pombi yemoto ine kuyerera kweyero isingasviki 500 gpm kunofanirwa kutsunga kudzivirira Kuoma mukushanda uye kusakwana kwekuyerera kwemoto kwakaitika. Uye zvakare, kutarisisa kunofanirwa kubhadharwa kune iyo nzvimbo yemagetsi emoto ane anotevera hunhu hunhu: iwo ari pane akafa-magumo mains, anoda zvakakosha zvekushandisa, ane chete 212-inch nozzles, uye haakwanise kushandisa madhiraini nekuti ari munzvimbo dzemafashama. kana kuti nzvimbo dzine mvura yakawanda yepasi. Zvinyorwa pasi apa ndezvimwe zvezvinetso zvinowanzoitika zvinokonzerwa nekuongorora nekugadzirisa kusina kukodzera, kushandiswa kusina kubvumirwa, uye kuparadza: Iro isingagoni kushandiswa tsvimbo kana nut inoshandiswa yakakuvadzwa zvakanyanya kuitira kuti wrench yemoto haigone kushandiswa; Munharaunda dzakawanda, dhipatimendi remvura romunharaunda rinogara richiongorora uye kuchengetedza marambi emoto. Izvi hazvibvisi vedhipatimendi remoto kuzviongorora pacharo kuti ive nechokwadi chekushanda kwakajairika kwepombi yemoto. Vashandi vekambani yeinjini vanofanira kupota vachitarisa chidhiraivho chemoto munzvimbo yavo yekupindura nekubvisa chivharo kubva pamuromo mukuru (waimbonzi "steam connector") nekukwesha dhiramu kuti vabvise marara. Ita bvunzo dzakadai panguva yekupindura kwearamu, zvibooreso, uye zvimwe zviitiko zvekunze kuti uite tsika. Chengetedza zvakanyanya kumagetsi emoto asina chivharo; zvidimbu zvinogona kunge zvakaiswa mudhiramu. Gezai marambi emoto achangobva kuiswa kuitira kudzivirira matombo akavharirwa mupombi huru uye pombi yekusimudza kubva pakukuvadza pombi nemidziyo. Aya anotevera mamwe mapoinzi akakosha nezve nzira dzekuchengetedza dzekuyedza uye kutsvaira ma hydrants emoto. Kutanga, pamudziyo wemoto une chivharo chakasimba panzvimbo, iva nechokwadi chekutarisa kuti uone kuti moto unovhara wakavharwa usati waedza kubvisa chivharo. Chechipiri, bvisa chivharo kubva pamuromo mukuru pane hydrant yemoto uye puruzira nepaburi rinonyatsoona kuti marara ese akaiswa anobviswa. Chechitatu, zvingave zvakakosha kuomesa zvimwe zvivharo kudzivirira kubuda kana, zvinonyanya kukosha, kudzivirira kuti chivharo chirege kupeperetswa nechisimba kana chivharo chemoto chikavhurwa. Chechina, gara wakamira kuseri kwegedhi remoto paunenge uchitsvaira. Sezviri pachena, kumira pamberi kana pedyo newe kunobvira zvikuru kunyorova; asi chikonzero chakanyanya kukosha chekumira kuseri kwegetsi remoto ndechekuti matombo nemabhodhoro akavharirwa mudhiri remoto hydrant barrel kana riser ichamanikidzwa pasi pekumanikidzwa kukuru Kuburikidza nemuromo, inova purojekiti ine njodzi. Mukuwedzera, sezvataurwa pamusoro apa, chivharo chinogona kuputika, zvichikonzera kukuvara. Imwe pfungwa yakakosha ine chekuita nedhigirii iyo vheji yekushanda inofanirwa kuvhurwa kuti inyatso kuburitsa hydrant yemoto. Ndakaona kuti mutyairi akavhura chidhiraivho chemoto kakawanda, achibvumira mvura kuti iyerere nemumuromo usina kuvharwa pasi pekumanikidzwa kukuru. Kudzvinyirirwa kwepamusoro uku kunogona kusunda magaba ealuminium, girazi nemabhodhoro epurasitiki, cellophane candy wrappers, uye mamwe madota ari pamusoro penhanho yenozzle uye kudzivirira kuti asaburitswe kunze kwedhiramu. Ipapo mutyairi akabva avhara gimbi rokudzima moto, akabatanidza pombi yokusveta, akavhurazve mudziyo wokudzima moto, uye akazadza pombi yemvura. Kamwe kamwe—kazhinji semubato wokutanga unopinda munzvimbo yemoto—mvura inoyerera sezvo marara asina kugezwa anopinda mumutsetse wokusveta. Mutsara wekurwisa wakave wakaremara, zvichiita kuti mudonzvo wenozzle uchinje nekukurumidza; pakadonha simba rekutora kusvika pazero, mutyairi akabva avhunduka. Nzira chaiyo yekugezesa inosanganisira kuvhura mupombi wemoto nguva shoma, kumirira nguva shoma, wobva wavhara chigero chekudzima moto kusvikira mvura yabuda yazadza hafu yemuromo wekuvhura (ona mufananidzo uri papeji 64). Kuparadza pachayo kunogona kudzima zvishoma kana kudzima zvachose ma hydrants. Ndinowanzosangana nemagetsi emoto ane zvivharo zvisipo, tambo dzakashaikwa (kazhinji pane 212-inch nozzles), asipo mavharuvhu mavharuvhu kana mabhaudhi pane anobvisa flanges, kushanda nzungu dzakasakara nekuda kwekushandiswa kusingabvumirwe, dzinongori nani kupfuura mapenzura Iyo dhayamita yakakura zvishoma. , iyo hood inoputika, bhomba rinomira nekuda kwekushandiswa kusingabvumirwi munguva yechando, iyo hydrant yemoto inoputirwa nemaune, uye dzimwe nguva inorasika zvachose. Matanho anotorwa kurwisa kuparadza. MuNew York City, marudzi mana makuru emidziyo yokuparadza akaiswa pamapombi emoto. Imwe neimwe yemidziyo iyi inoda chipanera chakakosha kana chishandiso chekushandisa, izvo zvinowedzera kuomesa basa remutyairi. Muzviitiko zvakawanda, pane zvigadziri zviviri pane imwechete moto hydrant-imwe chigadziro chinoshandiswa kudzivirira chivharo kuti chirege kubviswa, uye yechipiri chigadziro chinoshandiswa kuchengetedza nut inoshanda kubva kushandiswa kusina kubvumirwa. Munharaunda zhinji, maturusi chete anodiwa kuisa pombi yemoto musevhisi chipanera chemoto uye imwe kana maviri adapta (yepasi rose yakarukwa kuStorz adapter, mavharuvhu ebhora kana mavharuvhu egedhi, uye mana-nzira mana emoto mavharuvhu ndiwo anonyanya kuzivikanwa. ) Asi munzvimbo dzemutaundi, uko kuparara kwakatekeshera uye kugadziridzwa kwepombi yemoto kunomutsa mubvunzo, mamwe maturusi akawanda angadiwa. Kambani yangu yeinjini muBronx inotakura gumi nemana emhando-hongu, gumi nemana akasiyana wrenches, mavhavha, mapulagi, adapta, uye mamwe maturusi, kungotora mvura kubva mupombi yemoto. Izvi hazvibatanidzi hukuru hwakasiyana uye mhando dzekusveta uye mahosi ekupa anodiwa pakubatana chaiko. Kazhinji, kambani yeinjini inoshanda yakazvimiririra kana maviri kana anopfuura makambani einjini anoshanda mukurongeka anotangisa mvura kubva kune yemoto hydrant. Kambani yeinjini imwe chete inogona kushandisa imwe yeaviri akajairika hose yekuisa nzira-yakatwasuka pombi kana kumberi kuisa uye reverse kuisa-kuisa mvura kubva kumagetsi emoto. Mukuisa kwakatwasuka kana kumberi (dzimwe nguva kunonzi "hydrant to fire" kuisa kana kuti "tandem" supply laying), midziyo yeinjini inopakwa pachombo chemoto pamberi pechivako chemoto. Imwe nhengo yakafamba pasi ndokubvisa mahosi akakwana kuti "avhare" hydrant yemoto, uku achibvisa mawrench anodiwa uye zvishongedzo. Kana imwe nguva vashandi ve "fire hydrant" vachipa chiratidzo, mutyairi wejini achaenda kune chivakwa chemoto nebasa repombi yemvura. Nhengo dzakasara mumudziyo wemoto dzinobva dzatsvaira hydrant yemoto, kubatanidza hose, uye kuchaja mutsara wekugovera maererano nekuraira kwemutyairi. Iyi nzira yakakurumbira nokuti inobvumira midziyo yejini kuti iiswe pedyo nechivako chemoto uye inobvumira kushandiswa kwezvibata zvakagara zvakabatanidzwa uye mapaipi edhiki. Zvisinei, ine zvipingamupinyi zvakawanda. Chinhu chekutanga chinokanganisa ndechekuti nhengo imwe inogara papombi yemoto, ichideredza nhamba yevanhu vari muchivako chemoto kuisa mubato wekutanga. Chechipiri chinokanganisa ndechokuti kana chinhambwe chiri pakati pemagetsi emoto chinopfuura mamita 500, kurasikirwa kwekukanganiswa kwepombi yemvura kunoderedza zvikuru kuwanda kwemvura inosvika pombi. Madhipatimendi mazhinji anotenda kuti mitsetse miviri ye212-inch kana 3-inch inogona kubvumira huwandu hwakakodzera hwemvura kuyerera; asi kazhinji, chikamu chiduku chete chemvura inowanikwa inoshandiswa zvinobudirira. Hose yedhayamita hombe [(LDH) 312 inches uye yakakura] inogona kushandisa zviri nani ma hydrants emoto; asi rinounzawo zvimwe zvezvinetso zvinokurukurwa mundima mbiri dzinotevera. Chimwe chinokanganisa chegadziriro yepamberi ndechokuti injini yemidziyo iri pedyo nechivako chemoto, uye midziyo yekusimudza inogona kusasvika panzvimbo yakanakisisa. Izvi zvinonyanya kuitika kune yechipiri-maturity manera kambani, iyo inowanzoita nenzira yakapesana kune yekutanga-kukura injini. Migwagwa nhete inokudza dambudziko racho. Kana iyo injini midziyo pachayo isingaratidzi kuve chipingamupinyi, saka hose yekugovera yakarara mumugwagwa inowanzoitika. Iyo LDH yakachajwa ichakonzera zvipingamupinyi zvakakura kune inotevera Ladder Company michina. Uncharged LDH inogonawo kukonzera matambudziko. Munguva ichangopfuura, moto wakamuka mumutsara wezvitoro muLong Island, New York, uye manera eshongwe akaedza kutyaira pamusoro petambo yakaoma yemasendimita mashanu yakaiswa neinjini yakatanga kupera nguva. Kubatana kwakabatwa pamucheto wekutsemuka kwevhiri rekumashure, kutyora gumbo remudzimi wemoto padhishi remoto, zvichiita kuti mutsara wekupa usashande. Chimwe chinyorwa pamusoro pemidziyo yemanera uye mitsara yekugovera: ita shuwa kuti mutambudzi uye anobuda kunze haana kudzikiswa asingazivi pahose, nokudaro achigadzira hose hose clamp. Mune zvakapesana kana "moto-kumvura" kesi, midziyo yeinjini inotanga kupakwa muchivako chemoto. Kana nhengo dzikawana moto unoda kushandiswa kwezvibato, ivo vachabvisa zvakakwana hose dzine nozzles kuti dziendeswe mukati uye kumativi echivako chemoto. Muzvivakwa zvine nhurikidzwa dzakawanda, zvakakosha kubvisa hosi dzakakwana kuti usvike kunzvimbo yemoto pasina "kupfupisa". Zvinoenderana nechiratidzo kubva kumushandi wenozzle, mukuru kana imwe nhengo yakasarudzwa, mutyairi anoenda kune inotevera hydrant yemoto, anoiedza, oipisa, uye anobatanidza pombi yemvura. Kana nhengo ikasangana nemoto wakakomba, inogona "kuisa pasi" mubato wechipiri muchivako chemoto kuti ushandiswe neimwe kambani yeinjini kana kuisa mapaipi makuru-akareba kuti ape pombi dzemanera dzinopinda kana manera eshongwe. Iyo New York City (NY) Dhipatimendi reMoto rinongoda kushandisa reverse laying (inonzi "post-stretching" kwenguva pfupi). Zvakanakira zvekuisa kumashure zvinosanganisira kusiya kumberi nemativi echivako chemoto chakavhurika kuti uise midziyo yekambani yemanera; kushandiswa kwakanaka kwevashandi nokuti mutyairi anogona kuita moto hydrant connection zvakasiyana; kushandiswa zviri nani kwemvura iripo nekuti injini iri papombi yemoto. Imwe yakashata yekurongedzerwa kurongeka ndeyekuti chero midziyo yakajairwa yakavakirwa pamidziyo inobviswa kubva kune tactical arsenal kunze kwekunge pombi yemoto ikaitika iri padyo nechivako chemoto. Chimwe chinokanganisa ndechekuti panogona kunge paine mubato wakareba wakagadzikwa uye kudiwa kwepombi yakakwira yekuyerera, iyo inogona kukundwa ne "kuzadza" chero 134 kana 2 inch pombi ine 212 inch hose kuderedza kurasikirwa kwekukwenya. Iyi nzira inobvumirawo sarudzo kubvisa 134-inch kana 2-inch hose uye kushandisa mubato mukuru kana mamiriro akashata uye achida kushandiswa. Kubatanidza nyeredzi ine gedhi kana "mbavha yemvura" mudziyo kune 212 inch hose kunopa kushanduka kukuru. MuFDNY, hurefu hunosvika matanhatu (mafiti mazana matatu) e134-inch hoses inotenderwa kuchengetedza pombi yekuburitsa kudzvanywa (PDP) mukati menzvimbo yakachengeteka uye inonzwisisika. Makambani mazhinji anongotakura hurefu huna chete, zvichiwedzera kuderedza inodiwa PDP. Chimwe chinokanganisa chekuisa kumashure ndechekuti kazhinji haigone kushandisa pre-yakabatana handrails. Kunyangwe ichi chiri chokwadi, uye kusati kwabatanidzwa kunobvumira kukurumidza kutumirwa kwemitsara yemaoko, dhipatimendi remoto rakanyanya kuvimba navo, uye mazuva ano vashoma vanodzima moto vanogona kunyatso fungidzira kuwanda kwemitsara yemaoko. Dambudziko guru rine pre-yakabatana mitsetse inogona kunge iri "saizi imwe inokodzera ese" maitiro. Kana pombi isina kureba zvakakwana, izvi zvinogona kukonzera kunonoka kukuru pakudiridza moto. Kunze kwekunge gadziriro dzaitwa pachine nguva kuwedzera pombi yakambobatanidzwa-izvi zvinowanzoitika kuburikidza nekushandisa nyeredzi dzine gedhi uye manifolds-moto unogona kukurumidza kubuda mukudzora. Kune rumwe rutivi, dzimwe nguva mutsara wakabatanidzwa kare wakareba. Mumoto wenguva pfupi yapfuura, injini yekutanga yakanga iri pamberi pechivako chemoto, uye inenge mamita 100 chete epoipi yaidiwa kusvika panzvimbo yemoto uye kunyatsovhara imba yemhuri imwe chete. Nehurombo, mapaipi maviri akabatanidzwa-akabatanidzwa akaitwa muchinjika-wakaiswa hose mubhedha aive ese mafiti mazana maviri pakureba. Kunyanya kinking kwakakonzera kurasikirwa kwemvura yakawanda, zvakakwana kumanikidza boka remuromo kubva mumoto. Zvichida nzira yakanakisa ndeyekushongedza imwe neimwe injini yemidziyo ine hose mutoro, ichibvumira yakatwasuka uye yakadzoserwa kuisa. Iyi nzira inobvumira yakakwira dhigirii yehunyanzvi kuchinjika paunenge uchisarudza hydrant uye nekumisa midziyo. Kusvika kuma1950, makambani akawanda einjini aive "maviri-zvidimbu" makambani, aisanganisira hose mota ine hose, fittings, uye nozzles, uye injini ine pombi uye kusveta zviteshi. Iyo hose ngoro ichave iri padyo nechivako chemoto kuti ifambise kupfupisa kureba kwetambo yekudhonza uye kubhadhara mutengo wekushandisa yayo "mota chubhu". Injini inozopa mvura kubva mugetsi remoto kuenda kungoro. Kunyange nhasi, pombi nhatu dzinenge dzinoshandiswa pasi rose, uye nzira dzakawanda dzekupa mvura dzedhipatimendi remoto dzinoda kuti injini yekutanga iiswe pedyo nechivako chemoto, kunze kwekunge chidzitiro chemoto chiri pedyo, injini yechipiri yakabatanidzwa kune hydrant yemoto uye inopa yekutanga. . Kubatsira kukuru kwekushandisa makambani maviri einjini kuvaka hurongwa hwekupa mvura ndeyekuisa injini yekutanga pedyo nechivako chemoto kuitira kukurumidza kutumirwa kwezvibato zvakagara zvakabatanidzwa. Sezvo madhipatimendi mazhinji emoto ane mwero wakaderera wevashandi, kureba kwetambo yemaoko kunofanirwa kuve kupfupi sezvinobvira. Mukuwedzera, nekuda kwekureba kwekupindura kure, mabasa mazhinji ekurwisa moto anotanga nebooster tank mvura kusvikira injini yechipiri inosvika pakugadza mvura yakanaka. Kubatsira kweiyi nzira pamusoro peyakatwasuka kana kumberi yekuisa ndeyekuti kana hydrant spacing ichipfuura 500 tsoka, injini yechipiri inogona kuendesa mvura kune yekutanga injini uye kukurira chero kukanganisa kurasikirwa kwekukanganisa mumutsara wekupa. Kushandiswa kwemahombe-mahosi makuru kunowedzera kuvandudza kushanda kwekushanda kwemvura. Kana kureba kwechivako chekudzima moto kwakakwira kupfuura hydrant yemoto uye iyo static pressure isina simba, iyi nzira icharatidzawo kuti inobatsira munzvimbo dzine zvikomo. Mamwe mamiriro ezvinhu angangoda kushandira pamwe kwemakambani einjini maviri kugadzira mvura ndeaya anotevera: Matanho chaiwo anoshandiswa nemakambani maviri einjini kugadzira hurongwa hwekupa mvura achaenderana nemamiriro emigwagwa, kudiwa kwemakambani emanera kupinda mumoto. chivakwa, uye nzira yekupindura yeinjini imwe neimwe.

Muzviitiko izvi, "tambo inobhururuka" yakareba mamita makumi mashanu inogona kutakurwa, inosanganisira hose yemasendimita matatu kana kupfuura, kuti ibatsire kusvika pamvura yemoto. Kana nyaya dzekumanikidzika dzichimuka, sezvinowanzoitika mumoto wakakura, makambani akawanda einjini yealarm anofanirwa kubatanidza chidimbu chehose yekuyamwa yakaoma kune hydrant yemoto kubvisa njodzi yekudonha yakapfava kana semi-yakaomarara. Pamusoro pekushandisa zvibatanidza zvinopfungaira, funga kubatanidza vharuvhu yebhora kana vharafu yegedhi kune 212-inch fire hydrant nozzle. Iwe unogona ipapo kubatanidza pombi yemvura kune gedhi rekupinda kuti upe humwe huwandu, hunogona kuuya hunobatsira kana pakaitika moto muzvivako zvisina munhu, zvakabatanidzwa kana kuti zvakaparadzana zvivakwa zvemapuranga, uye nzvimbo huru dze "vateresi". Munzvimbo dzepamusoro-soro uko ma hydrants akapatsanurwa zvakanyanya, injini imwe inogona kubatanidzwa kune maviri hydrants. Mamwe maguta achiri kuchengetedza hurongwa hwemvura inodzvanywa, iyo inogona kubvumira injini mbiri kugovera mudziyo wemoto. Munguva yechando, funga kuvhara majoini ese ari pachena ekuyamwa hose nealuminium foil kudzivirira sinou uye icing, inogona kuvhara hose kana kudzivirira majoini echikadzi anotenderera kuti asatenderere zvakasununguka. Mumwe mutyairi mukuru weFDNY Engine Company 48 akagadzira izwi rekuti "maminetsi maviri ekutyisa" paaitsanangura chiitiko chemaminitsi maviri ekutanga chemutyairi weinjini yekutanga panzvimbo yemoto. Mukati maminetsi maviri (kana pasi), mutyairi anofanira kuisa midziyo yeinjini pedyo negetsi remoto, kutsvanzvadzira kuti aedze uye apise hydrant yemoto, kubatanidza hose yekusveta, jekiseni mvura mupombi, uye kubatanidza mubato kumusuwo wekubuda (kana ita shuwa kuti Iyo yakabatana hose mubhedha inobviswa kubva papombi), uye pombi inobatanidzwa. Ndinovimba kuti mabasa ese aya apera mupurisa asati adaidza mvura. Semutyairi, rimwe zita remadunhurirwa rausingade ndi "Sahara". Kana iyi isiri mutoro wakakwana, saka maminitsi maviri anotsanangurwa pamusoro apa anonyanya kutyisa mukati meguta remukati, nokuti kune mibvunzo mina inokosha yekuwana mhinduro: 3. Kana iyo hydrant yemoto yakarurama uye yakagadziriswa, mvura ichayerera panguva yekuedzwa, kana kuti ichatsemuka kana kuoma nechando? 4. Kana chidzitiro chemoto chiri kushanda zvakanaka, chivharo chinogona kubviswa mukati menguva yakafanira yekubatanidza hose yekusveta here? Kuti unzwisise zviri nani matambudziko anosanganikwa nawo nemapombi emoto munzvimbo dzine kukuvara kwakanyanya uye kuti sei nyaya ina idzi dzakakosha, funga nezvezviitiko zvitatu zvinotevera. Mutyairi wekambani yakabatikana yeSouth Bronx Injini akatanga kuita nekuda kwemoto mufurati rebasa. Mushure mekunge amira pamberi pechivako chemoto kuti abvumire mubato kuti uwedzere, akaenderera mberi nekuwana chigero chemoto padivi pe block. Yekutanga "pombi yemoto" yaakawana yakanga isiri hydrant yemoto, asi ingori bhaketi rezasi rinobuda kubva pasi-iyo hydrant yemoto pachayo yakanga yaenda zvachose! Sezvaairamba achitsvaga, chigero chekudzima moto chakatevera chaakawana chakanga chakarara nedivi. Pakupedzisira, akaona chigero chemoto chakamira, chinenge chinhambwe nechidimbu kubva pachivako chemoto; rombo rakanaka, rakaratidza kuti raishanda. Vamwe mukambani yake vakanyunyuta kwemazuva anoverengeka pamusoro penguva yavakanga vatora pombi nokuisazve paipi, asi mutyairi akaita basa rake uye aiva nechokwadi chokuti mvura inoramba iripo kana vatarisana nezvinetso zvikuru. Pakasvika mutyairi mukuru kubva kuchamhembe kwakadziva kumabvazuva kweBronx, akaona moto wakakomba pauriri hwekutanga hwefafitera reimba inogarwa nevanhu. Pane pombi yemoto padivi pemugwagwa, inoratidzika kunge inokurumidza uye iri nyore kubatanidza. Asi chitarisiko chinogona kunyengera. Mutyairi akaisa chipanera pane nati yokuvhiya ndokuivhura nerevhisi, uye mudziyo wose wokuisira moto wakawira kurutivi rumwe! Asi asati aenda kune chimwe chigero chekudzima moto chinotevera, akazivisa vakuru vakuru vake kuburikidza neredhiyo inotakurika kuti paizova nekunonoka kwemvura (uye akazivisa kambani yeinjini kuti yaifanira kuuya kechipiri, kana yaida rubatsiro). Pamusoro pekutaura chero kunonoka kana zvimwe zvinhu, kana mvura iri mutangi yakamanikidzwa yapihwa netambo yeruoko, vakuru vakuru kana timu yemuromo inofanirwa kuziviswa nezvechokwadi ichi. Kana mvura ye hydrant yavepo, ruzivo urwu runofanirawo kuziviswa kuvakuru uye timu yenozzle kuitira kuti vagone kushandura zano ravo zvinoenderana. Pane imwe pfungwa: vatyairi vakanaka vanogara vachichengetedza tangi yakakwana yebooster panguva yekushanda, sechiyero chekuchengetedza, kana moto wemvura usina mvura. Ini ndichapa muenzaniso wega kuti ndiratidze matambudziko anowanzo sangana pakuedza kubvisa chivharo chikuru kubva pamoto hydrant steamer connection. Sezvo anti-vandal mudziyo nebutiro zvakanamira kana kuomeswa nechando panzvimbo, vatyairi vekambani yedu vanowanzoshandisa nyundo kurova chivharo chega chega, vachishandisa zvibhakera zvakati wandei. Kurova chivharo nenzira iyi kuchaparadzira marara akavharirwa mushinda, uye chivharo chinogona kubviswa nyore nyore. Mwedzi mishomanana yapfuura, ndakanzi nditange kambani yeinjini muUpper Manhattan. Panenge pa5:30 mumangwanani, nokuda kwomwoto weimba ine mhuri dzakawanda, iyo gare gare yakabvumikisa kuva mwoto unouraya, takatanga kutumirwa. Nekuda kwetsika, ndakaisa 8-pondo maul pakutanga kwekushanya munzvimbo yakajairika pane rig, kana ndikaida. Chokwadi, chivharo chepombi yemoto chandakasarudza chaida kugogodza kakawanda kubvisa chivharo nechipanera. Kana kurova kwakawanda nesando (kana kumashure kwedemo, kana pasina nyundo) usasunungura chivharo zvakakwana kuti ubvumire kubviswa, unogona kutsvedza chikamu chepombi kuburikidza nemubato wechipanera chemoto kuti uwane kuwedzera kukuru. Ini handikurudzire ndaona wrench bend uye kutsemuka nekudzvanya pamubato we wrench pachayo. Kushandiswa kunobudirira kwemagetsi emoto kunoda kufanoona, kudzidziswa uye kufunga nokukurumidza panzvimbo yemoto. Midziyo yeinjini inofanira kunge yakashongedzerwa kupindura kune dzakasiyana siyana dzekupa mvura, uye vatyairi vanofanirwa kuve neredhiyo inotakurika kuti ivandudze kutaurirana kwemoto. Kune akawanda akanakisa mabhuku ekuverenga einjini mashandiro ekambani uye maitiro ekupa mvura; ndokumbirawo uvabvunze kuti uwane rumwe ruzivo pamusoro pemahosi anokurukurwa muchinyorwa chino nezvimwe zvine chekuita nenyaya.
