Ukuba ucinga ukuthenga i-roller yendlela esetyenzisiweyo, okanye i-contractor yendlela, kuya kufuneka ukhethe ukusuka kuluhlu lwezinto onokukhetha kuzo. Kukho iintlobo ngeentlobo zeerola zendlela: igubu elinye neliphindwe kabini, iirola ezingcangcazelayo, i-sheepsfoot/padfoot kunye ne-pneumatic rollers.
Iirola zendlela ziqhele ukusetyenziswa kwinqanaba lokugqibela lokwakhiwa kweendlela ukuya kwi-compact kunye ne-asphalt yezinga, umhlaba, i-gravel okanye udongwe, kunye nohlobo lwezinto eziza kuhlanganiswa lunquma uhlobo lwe-roller. Ngenxa yokusetyenziswa okuthe ngqo kunye nokunqongophala kwezi ziqengqelezi kwiprojekthi yolwakhiwo lwendlela, zinokuvela kwimarike yesibini kunye nokuguga okuncinci. Oku kunokubenza bakhethe ixabiso elifanelekileyo kumthengi onolwazi ofuna ukugcina iindleko zokwakha ziphantsi.
Eli nqaku lijonge ukhetho lwee-roller zendlela ezifumanekayo kwimarike yesandla sesibini, kwaye inika iingcebiso malunga nendlela yokuphucula amathuba akho okuthenga ixabiso elihle.

Imarike esetyenzisiweyo yerola yendlela
Imarike yokwakha yehlabathi ikwinqanaba lokukhula, iphuma kwi-hiatus ende ngexesha lobhubhani wamva nje. Ukukhula kweziseko ezingundoqo kunye neeprojekthi zolwakhiwo, kuqikelelwa kwizinga lokukhula elihlanganisiweyo lonyaka (CAGR) malunga ne-4.7% nge-2027, izisa imfuneko yezixhobo zokwakha.
Nangona kunjalo, iinkampani ezininzi zokwakha zineendleko kunye noxinzelelo lokuhamba kwemali, kwaye ziyathandabuza ukwenza utyalo-mali kwizixhobo ezitsha, ngakumbi xa kunikwa ukungaqiniseki malunga nokusinda kweprojekthi. Yenza ingqiqo yezemali ukugcina iindleko zezixhobo ziphantsi. Utyalo-mali kwizixhobo ezinokusetyenziswa kancinci kwiprojekthi, njengeerola zendlela, lufuna ukuqwalaselwa ngenyameko.
Ngoko ke ukhetho lobulumko kukukhangela izixhobo ezisetyenzisiweyo ezinexabiso elilungileyo, ezicutha iindleko zotyalo-mali ngelixa zinciphisa ukuthotywa, kwaye zinokuzisa ixabiso elihle lokuthengisa kwakhona kamva. Imarike yezixhobo zokwakha ezisetyenzisiweyo isempilweni kakhulu ngoku, ibonisa ingqikelelo I-CAGR emalunga ne-5.8% ukusuka ngo-2023 ukuya ku-2028, ebonisa umnqweno wokuba iinkampani zijonge iinketho zesandla sesibini ngaphezu kokutsha.
Yintoni onokuyijonga kwi-roller yendlela esetyenzisiweyo
Iirola zendlela ziza kwiindidi ezahlukeneyo, ezinezixhobo ezahlukeneyo zokuqengqeleka, ubukhulu obuhlukeneyo kunye nobunzima. Injongo ye-roller yendlela kukudibanisa kunye nokulinganisa umhlaba phantsi kwayo, ngoko ke izinto eziphambili zibubanzi kunye nobunzima be-roller, kunye nendlela esetyenziswa ngayo phantsi. Ngaphandle kwale miba, kukho ingxaki encinci kakhulu ngaba matshini, kwaye okoko begcinwe kakuhle, akukho sizathu sokwenyani sokuba bangakwazi ukuhlala iminyaka emininzi. Oku kubenza bathenge ngesandla sesibini esilungileyo kunye nokuthengisa okulungileyo emva kokuba begqibile ukusebenzisa iprojekthi yabo.
Ukuthenga i-roller yendlela esetyenzisiweyo kwi-intanethi ifuna ukuhlolwa ngokomzimba ukuze kuqinisekiswe ngokufanelekileyo imeko. Nazi iindawo ezimbalwa ezibalulekileyo ekufuneka uzihlole:
Ukuhlola okubonakalayo
Iingcali zicebisa ukuqala uhlolo olubonakalayo ukusuka ezantsi kwi-roller yendlela. Okokuqala jonga i-undercarriage, emva koko uhlole isakhelo, emva koko zonke ezinye iindawo zangaphandle. Ngaba umatshini ujongeka ugcinwe kakuhle kwaye ukwimeko entle? Ukuba umatshini umdaka, ngaba kubonakala ngathi ukungcola kufihla umhlwa okanye ipeyinti exotyiweyo? Ukuba umzimba ubonakala uhlanjululwe kwakhona, oku kunokubonisa umhlwa odlulileyo oye wagqunywa. Jonga i-bodywork for naziphi na iimpawu ze-welding, okanye ii-fishplates ezongeziweyo njengoko ezi zibonisa umonakalo owenziwe ngaphambili.
Phonononga iirekhodi zogcino
Iirekhodi zogcino zibonisa ukuba i-roller yendlela ibisenziwa rhoqo kangakanani na, xa ii-oyile nezihluzo bezitshintshwa, kwaye rhoqo. Khangela oku ngokuchasene neenkcukacha zomenzi. Khangela ukuba kukho naziphi na iirekhodi zamalungu amakhulu atshintshiweyo. Ukuba kunjalo, kusetyenziswe iindawo ezisemgangathweni? Xa ukugcinwa kunye neenkcukacha zokulungisa ziyaziwa, oku kunceda ukuhlola umatshini ngeliso elibukhali.
Jonga injini
Qhuba i-injini kwaye ukhangele iimpawu zokuvuza okanye ukunkqonkqozwa kwi-injini. Ngaba kukho umsi omhlophe okanye omnyama ophuma kumbhobho onokubonisa imiba yokutshiswa kwamafutha? Ukuba i-injini iqinisekisiwe nge-Euro 5 okanye i-Euro 6, yenza uvavanyo lokukhutshwa kwe-injini ukujonga ukuba i-exhaust isekuluhlu. Khangela ioli kunye Isihluzi somoya iimeko kwaye uzithelekise nerekhodi yokugcina. Ukuba i-injini yeyokupholisa umoya endala, khumbula ukuba ezi zifuna ukulungiswa rhoqo, kwaye isihluzo somoya siya kufuna ukutshintshwa rhoqo, ngakumbi kwindawo enothuli. Ukuba i-injini ipholile ngamanzi, khangela ukuba kukho nakuphi na ukuvuza okuya kuchaphazela ukuhamba kwamanzi.
Jonga i-cab yomsebenzisi
Nangona i-cab emdaka, enothuli kwaye egugileyo ayichaphazeli ukusebenza komatshini, inika isalathiso sendlela umatshini uphathwe ngayo. Isitulo esigugileyo sinokutshintshwa ngokulula, kwaye iifestile ezikrweliweyo zinokutshintshwa. Okona kubaluleke ngakumbi, ngaba iipedali, izixhobo kunye neegeyiji ziyasebenza? Ngokuxhomekeke kuhlobo lwe-roller yendlela, kukho ezinye izinto zokujonga. Kwi-roller yendlela eshukumayo, khangela ukuba iindlela zokungcangcazela zisebenza ngokusebenza kumatshini. Ngaba kukho i-frequency ephezulu, okanye useto lwe-amplitude ezimbini, kwaye ukuba kunjalo ziyasebenza? Jonga i-articulation joints ngokuqhuba i-roller.
Jonga ii-hydraulics
Jonga iisilinda zehydraulic ukuba zimoshakele. Khangela ukuba yonke imibhobho itywiniwe kwaye akukho zimpawu zokuvuza. Qwalasela irekhodi yogcino ukuba kukangaphi na ulwelo olwenziwa ngolwelo olwenziwa ngamanzi aphantsi kolwelo longeziweyo. Ukunyuka okuthe gqolo kungabonisa ukuvuza.
Hlola amatayara kunye ne-chassis
Kwii-roller ze-drum ezinamavili amabini kunye ne-pneumatic rollers, jonga imeko yesondo yangasemva yokunxiba okanye ukuqhekeka. Jonga iinkcukacha zerola kwaye uqinisekise ukuba amavili afanelekileyo afakelwe. Khangela ukuba iirimu zamavili kunye neeasi zikwimeko entle. Kwiirola ze-pneumatic, jonga amatayara e-roller angaphambili ukuba anxibe kunye noxinzelelo kunye nokulungelelaniswa.
Hlola igubu, kwiirola zegubu elinye neliphindwe kabini
Kwimiqengqeleki eyodwa kunye nephindwe kabini, kubalulekile ukuqinisekisa ukuba igubu ngalinye likwimeko entle. Ukuba igubu lonakele oku kuya kuba nefuthe kwisakhono sokuhlanganisa kwaye ukuba sonakaliswe kakhulu kuya kuba yindleko yokutshintshwa. Amagubu kufuneka abe mtyibilizi, kodwa amatye aqinileyo kunye nezinye izinto zinokubobotheka, ziligrumbe kwaye ziliva igubu. Umphezulu kufuneka ugudiswe ukuze unike isiphelo esilinganayo endleleni. Khangela ukuba ubungqingqwa begubu abucuthwanga ngokugqithisileyo ngokuguga. Kwimigqomo yonyawo lwegusha okanye unyawo lwegusha, iinyawo akufunekanga zibotshwe okanye zinxitywe. Ukutshintshwa kuya kuba yindleko enkulu.
Hlola iindawo ezidibeneyo
Amalungu adityanisiweyo phakathi kwe-chassis yangaphambili nasemva kufuneka ibe kwimeko efanelekileyo, njengoko kubalulekile ukukwazi ukuqhuba i-roller. Qhuba i-roller ngasemva nangaphambili kwaye ukhangele ukuba ihamba ngokuchanekileyo. Qwalasela amalungu, ukuthambisa kunye namafutha, bushings kunye nezikhonkwane. Oku kuya kuba yindawo ebiza kakhulu ukuba kukho iingxaki ezinkulu.
Ukhetho olukhoyo kwiirola zendlela ezisetyenzisiweyo
Kumthengi onokubakho, kukho ukhetho olukhoyo olukhoyo kwimakethi yesandla sesibini. Ezinye iintlobo zibonakala zixhaphake kakhulu kunezinye njengoomatshini abasetyenzisiweyo. Iirola zomgqomo omnye ziqhelekile kwaye zininzi, kunye noluhlu lwabavelisi, abaziwayo kunye neempawu ezingaziwayo. Iirola eziphindwe kabini zomgqomo zibonakala zincinci kancinci njengoomatshini abasetyenzisiweyo, kodwa ukhetho oluninzi lwabatsha. Iirola ze-pneumatic ngesandla sesibini kunye ne-padfoot rollers zilinganiselwe kwiimpawu ezimbalwa. Nalu ukhetho lweentlobo, iibrendi kunye namaxabiso akhoyo kwimarike ye-intanethi:
