Umhlinzeki wemishini yokwakha wezixazululo zemishini yokwakha iminyaka engama-30.
Ukuthenga i -trowel enamandla okugibela kubukeka kulula kuze kube yilapho umshini ufika endaweni yokusebenza futhi ukhonkolo uqala ukusethwa ngokushesha kunokulindelekile. Abakhi abaningi baqhathanisa intengo kuqala, injini ilandela, futhi cishe konke okunye kamuva. Lokho kuhleleka kuvame ukuholela ekusebenzeni kahle kokuqeda, ukukhathala komqhubi, izindleko zokulungisa eziphezulu noma umshini omkhulu kakhulu, omncane kakhulu noma onzima kakhulu ukuwulawula nge-slab yangempela. I-trowel yokugibela ukhonkolo kufanele ikhethwe ngokuya ngobukhulu be-slab, ububanzi bokusebenza, uhlelo lwe-blade, uhlobo lokuqondisa, amandla enjini, ukufinyelela indawo kanye nokusekelwa kwensizakalo yesikhathi eside. Intengo ibalulekile, vele, kodwa ukhonkolo awuvamile ukulinda ngenhlonipho ngenkathi umthengi eqaphela ukuthi u-ode umshini ongalungile.
Umshini wokuqeda ukhonkolo oshibhile kakhulu ungase ubukeke umuhle ephepheni lesilinganiso, kodwa izindleko zangempela ziyavela ngesikhathi sokuthulula. Uma i-trowel ingakwazi ukumboza i-slab ngaphakathi kwefasitela lokuqeda, ithimba lingadinga abasebenzi abengeziwe, ama-trowel engeziwe okuhamba ngawo noma ukwesekwa okuphuthumayo kokuqasha. Uma ibhokisi legiya, izingalo zama-blade noma uhlelo lokuqondisa luguga ngokushesha, ukonga kuyanyamalala ezingxenyeni ezisele kanye nesikhathi sokungasebenzi. Indlela engcono yokuqhathanisa intengo ukubuza ukuthi umshini ungaqeda ini ngehora, ukuthi usebenza kanjani njalo ngaphansi komthwalo, nokuthi kulula kangakanani ukuwunakekela ngemva kokusetshenziswa okuphindaphindiwe ezindaweni zekhonkolo ezirhabaxa.
Kubathengisi nezinkampani eziqashisayo, leli phuzu libaluleke nakakhulu. Umshini oshibhile onezingxenye ezibuthakathaka ungaba nzima ukuwuqasha ngemva kwesizini yokuqala. Abakhi bakhumbula imishini ebasiza ukuba baqede kahle, futhi bakhumbula nemishini ema phakathi kwe-slab.
I-trowel kagesi yokugibela iwusizo kakhulu ezitezi ezinkulu zikakhonkolo ezivulekile njengezindawo zokugcina impahla, amafektri, izakhiwo zokupaka, izikhungo zezokuthutha kanye nama-slab ezimboni. La maphrojekthi adinga ukumbozwa okusheshayo kanye nekhwalithi ephezulu ehambisanayo endaweni ebanzi. Kodwa-ke, i-trowel yokugibela ayiyona impendulo efanele ngokuzenzakalelayo kuyo yonke imisebenzi. Uma phansi kunezinsika eziningi, ama-bay amancane, imiphetho yodonga, iziteshi zokukhipha amanzi noma amakamelo amancane, umqhubi angachitha isikhathi esiningi ejika futhi elungisa isiqondiso. Kuleso simo, umshini ohamba ngemuva ungase usadingeka emaphethelweni nasezindaweni ezivinjelwe.
Ngaphambi kokuthenga, qagela ubukhulu beslabhu obujwayelekile abasebenzi bakho ababuphathayo, hhayi nje umsebenzi omkhulu onethemba lokuwuwina. Umakhi osebenza kakhulu kumaslabhu okuhlala akadingi umshini ofanayo neqembu eliqeda ama-apron asesikhumulweni sezindiza noma phansi kwendlu yokugcina impahla enabantu abaningi. Ukufanisa umshini nomsebenzi ojwayelekile kuletha imbuyiselo engcono kunokuthenga imodeli enkulu kunazo zonke ukuze isetshenziswe ngezikhathi ezithile.
Ububanzi bokusebenza buthinta umkhiqizo, ukukwazi ukuqondisa kanye nokulawula indawo. Ububanzi bokusebenza betrowel yokugibela ebanzi buyasiza ukumboza ama-slab amakhulu ngokushesha, kodwa futhi budinga isikhala esengeziwe sokujika kanye nokuhlela okwengeziwe kwezokuthutha. Imodeli encane yokugibela ingaba lula ukuyihambisa, kube lula ukuyifunda futhi ifaneleke kakhulu ezitezi zezentengiselwano eziphakathi nendawo. Yingakho abathengi kufanele baqhathanise ububanzi bokusebenza kanye nesisindo somshini, usayizi we-blade kanye nokwakheka kwendawo.
Isibonelo, i-trowel encane yokugibela ingaba usizo lapho ukufinyelela kwezokuthutha kulinganiselwe noma lapho unkontileka edinga umshini ongena kusenesikhathi ku-slab. I-trowel enkulu yokugibela ye-hydraulic ifaneleka kakhulu uma okubaluleke kakhulu kungumkhiqizo ophezulu wansuku zonke, ingcindezi yokuqeda eqinile kanye nezikhathi zokusebenza ezinde phansi evulekile. Okukhulu kungaba ngcono, kodwa kuphela uma indawo inikeza indawo yomshini indawo yokusebenza.
Uhlobo lwenjini lubalulekile, kodwa akuyona indaba yonke. Abathengi kufanele baqhathanise amandla enjini, isivinini esiphezulu, umthamo kaphethiloli, indlela yokupholisa, ibhalansi yesisindo kanye nendlela amandla adluliselwa ngayo ezitsheni. Umshini onenjini ehlonishwayo kodwa ohambisana kahle nesakhiwo ungase uzizwe ubuthakathaka ngaphansi komthwalo wokuqeda. Ngakolunye uhlangothi, amandla amaningi emshinini olinganiswe kabi angenza ukulawula kube nzima, ikakhulukazi kubasebenzisi abangenalo ulwazi oluningi.
Umbuzo wokuthenga osebenzayo ulula: ingabe injini, i-gearbox kanye nohlelo lwe-blade kuzogcina ukusebenza okuzinzile ngesikhathi sokuntanta nokuqeda amaphasi? Kuma-slab asindayo, izimo zomphezulu owomile noma amahora amaningi okusebenza, umkhiqizo ozinzile ubaluleke ngaphezu kwenombolo eyodwa ehlaba umxhwele encwajaneni. Abakhiqizi kufanele futhi baqinisekise ukuthi injini ijwayelekile emakethe yabo yendawo, ngoba ukufinyelela kalula ezihlungi, ama-spark plugs kanye nolwazi lwesevisi kunciphisa ingozi yesikhathi eside.
Abathengi abaningi babuza ngamamodeli e-hydraulic ride-on power trowel kuphela ngemva kokuba behlupheke ngokukhathala komqhubi. Ukuqondisa ngomshini kuvame ukuba lula, kube lula futhi kungabizi kakhulu, okwenza kufaneleke emisebenzini eminingi ejwayelekile. Ukuqondisa ngomshini kunganikeza ukulawula okubushelelezi nokusebenza okulula kuma-slab amakhulu, ikakhulukazi lapho umqhubi edinga ukusebenza isikhathi eside. Ukukhetha okulungile kuncike esikalini sephrojekthi, ikhono lomqhubi kanye nokusetshenziswa komshini okulindelekile.
Uma umshini uzosetshenziswa ngezikhathi ezithile, imodeli yomshini inganikeza inani elihle. Uma uzosetshenziswa njalo ezitezi ezinkulu zezimboni, uhlelo lwe-hydraulic lunganciphisa ukukhathala futhi luthuthukise ukuhambisana kokulawula. Lokhu akuyona nje inkinga yokududuzeka. Umsebenzisi okhathele wenza amaphutha amaningi okuqeda, futhi amaphutha okuqeda ayabiza uma i-slab isiqinile.
Umshini we-trowel kagesi wekhonkrithi wahlulelwa ngephansi elishiya ngemuva. Ijubane le-blade, ukulungiswa kwe-blade pitch, ukuhambisana kwepani elintantayo kanye nekhwalithi ye-blade yokuqeda konke kuthinta umphumela wokugcina. Ngesikhathi sokuntanta kwasekuqaleni, umshini kumele usakaze ingcindezi ngaphandle kokudabula indawo. Ngesikhathi sokuphetha kamuva, i-blade pitch kumele ilungiswe ngokwanele ukudala isiphetho esiqinile, esibushelelezi ngaphandle kokushisa noma ukumaka i-concrete.
Abathengi kufanele babuze ukuthi umshini uyawasekela yini amapani antantayo kanye nama-blade okuqeda afanele izidingo zabo zokuxuba ukhonkolo kanye ne-slab. Kufanele futhi bahlole ukuthi i-engeli ye-blade ingalungiswa kalula kangakanani kusukela endaweni yomqhubi. Umshini onamandla onokulawulwa kabi kwe-blade ufana nesisebenzi esinamandla esinamabhuzu ashelelayo: esinamandla, kodwa awusizo ngaso sonke isikhathi.
Uhlu lokuhlola ukulungiswa kwe-trowel yamandla okugibela kufanele lube yingxenye yesinqumo sokuthenga, hhayi ukucabanga kamuva. Amaphuzu abalulekile okuhlola afaka phakathi ukuguguleka kwe-blade, isimo sebhande, ukugcotshwa kwegiya, izinga likawoyela we-hydraulic, impendulo yokuqondisa, uwoyela wenjini, isihlungi somoya, iswishi yokuphepha kanye nama-bolts axegayo. Imishini yokuqeda ukhonkolo isebenza othulini, ezimweni zokudlidliza nasezimweni zomphezulu omanzi, ngakho-ke ukuhlanza nokuhlola okuvamile kuthinta ngqo impilo yesevisi.
Kubathengi baphesheya kwezilwandle, ukutholakala kwezingxenye ezisele kuvame ukuba kubaluleke kakhulu kunesaphulelo esincane. Abathengisi kufanele baqinisekise izingxenye ezivamile zokuguguleka ngaphambi kokufaka imodeli, kuyilapho osonkontileka kufanele babuze ukuthi ama-blade, amapani, amabhande, izihlungi kanye nezingxenye zokuqondisa zinganikezwa ngokushesha kangakanani. Ukusekelwa okuhle kuguqula umshini ube yimpahla. Ukusekelwa okubi kuguqula ube yisihlalo esikhulu sensimbi esinenjini enamathiselwe.
Ngaphambi kokufaka i-oda, hlola usayizi weslab ojwayelekile, ikhwalithi yokuqeda edingekayo, ububanzi bokusebenza, amandla enjini, uhlobo lokuqondisa, ukuhambisana kwe-blade, isisindo somshini, ubukhulu bezokuthutha, induduzo yomqhubi, iswishi yokuphepha, ukukhanyisa, uhlelo lokufafaza amanzi, ukuhlinzekwa kwezingxenye ezisele kanye nezinketho zesevisi yendawo. Uma uthenga izitezi zokugcina impahla, izitezi zezimboni noma amaslabhu amakhulu ekhonkrithi, beka phambili umkhiqizo, ukulawula okuzinzile kanye nesikhathi esincane sokungasebenzi. Uma uthenga amaphrojekthi axubile, khetha imodeli elinganisela ukumbozwa kanye nokuguquguquka.
Ukuthenga okuhlakaniphile kakhulu akuyona njalo imishini ebiza kakhulu noma eshibhile kakhulu. Yi-trowel yamandla okugibela efanelana nomsebenzi wakho wekhonkrithi, iqembu lakho, indlela yakho yokuthutha kanye nekhono lakho lokulungisa.
Khetha usayizi ngokuya ngendawo yeslabhu, indawo yokusebenza evulekile kanye nefasitela lokuqeda. Izitezi ezinkulu ezivulekile zivame ukuzuzwa yimishini ebanzi, kuyilapho amaslabhu aphakathi noma izindawo ezinemingcele yokufinyelela zingadinga imodeli encane kakhulu yokuhamba.
Kungcono ezitezi ezinkulu, ezivulekile lapho umkhiqizo kanye nenduduzo yomqhubi kubalulekile khona. I-trowel ehamba ngemuva isasebenza emaphethelweni, amakamelo amancane kanye nezindawo ezinemininingwane lapho umshini wokugibela ungeke ukwazi ukuhamba ngokukhululeka.
Khetha isiteringi se-hydraulic lapho umshini uzosetshenziswa kaningi kuma-slab amakhulu futhi induduzo yomqhubi ibalulekile. Isiteringi se-mechanical sisengaba yisinqumo esiwusizo somsebenzi ojwayelekile kanye nezindleko eziphansi zobunikazi.
Hlola ububanzi bokusebenza, amandla enjini, ukulungiswa kwephimbo le-blade, uhlobo lokuqondisa, isisindo somshini, usayizi wezokuthutha, izici zokuphepha, ukuhlinzekwa kwezingxenye ezisele kanye nokusekelwa kwangemva kokuthengisa.
