Chaza uxinzelelo oluphantsi lomhlabaIingoma ze-ASV

Kwimisebenzi yezixhobo ezinzima, ukusetyenziswa koomatshini kwiindawo ezinzima ngokusisiseko kuxhomekeke kulwakhiwo olufanelekileyo lwesithuthi esingaphantsi komhlaba. Xa kuvavanywa ii-compact track loaders (ii-CTL) kwiindawo ezibuthathaka okanye ezingazinzanga, ukufikelela kuxinzelelo oluphantsi lomhlaba (ii-LGP)—ngesiqhelo phakathi kwe-2.5 kunye ne-4.5 psi kwiimashini ezinobunzima obuyi-6,000 ukuya kwi-12,000 lbs—yinjongo ephambili. Kubalulekile ukwahlula phakathi kwee-OEM tracks ezenzelwe ngokukodwa iimashini ze-ASV—uphawu oluthile lwe-OEM oludumileyo ngeenkqubo zalo ze-Posi-Track undercarriage—kunye nee-aftermarket tracks ezihambelana nee-ASV undercarriages. Akukho nanye kwezi zixhobo zokuhlaziya ezisetyenziswayo kuzo naziphi na iinqanawa ze-CTL; zizinto ezithile zoomatshini ezenzelwe ukudibanisa neenkqubo zokumiswa ezikhethekileyo.

Ngokusasaza ubunzima bokusebenza bomatshini ngokulinganayo kwindawo ebanzi yoqhagamshelwano, ezi ndlela zikhethekileyo zinokufikelela kuxinzelelo oluphantsi kakhulu lokuthwala umhlaba (ngokuqhelekileyo ngaphantsi kwe-3.5 psi), zigcina oomatshini behamba phezu komhlaba apho izixhobo eziqhelekileyo zinokutshona khona okanye zibangele ukuguguleka kwendalo. Khumbula ukuba ukubalwa koxinzelelo lomhlaba kuxhomekeke ngokupheleleyo kubunzima bokusebenza komatshini othile kunye nokusasazwa komthwalo, kungekuphela nje ububanzi bomzila ngokwawo.

Landelela Izinto Zoyilo Eziphucula Ukudada

Ukutyibilika okuphezulu kwezi ndlela kuvela ngqo kubunjineli bazo bangaphakathi kunye nesithuthi esingaphantsi kwesitimela esinye se-ASV Posi-Track esixhonywe ngokukodwa. Olu lwakhiwo lwendlela evulekileyo yeyona nto iphambili eyenza ukuba iindlela ze-ASV zibe zezomatshini kwaye zisebenzisa ulwakhiwo lwerabha kunye nefayibha edityanisiweyo endaweni yeentambo zentsimbi zemveli. Ngokungafaniyo neendlela ze-CTL eziqhelekileyo ezifakwe kwintsimbi enzima,Iingoma ze-OEM ASV—kunye nee-premium aftermarket equivalents—zakhiwe ngee-cords ze-aramid eziqhubekayo okanye ze-Kevlar. Olu lwakhiwo olungeyontsimbi lususa ubunzima obubalulekileyo obungafakwanga kwi-undercarriage, ludla ngokunciphisa ubunzima bomkhondo nge-15% ukuya kwi-20% xa kuthelekiswa nee-equivalents ezifakwe kwintsimbi.

Nangona ukuphuculwa ukuya kwiprofayili ebanzi yendlela (umz., ukusuka kwi-15-intshi eqhelekileyo ukuya kububanzi be-LGP obuyi-intshi eziyi-18 okanye ezingama-20-intshi) kwandisa indawo yokunxibelelana nomhlaba kwaye kunciphisa iipawundi nge-square intshi (psi) nganye esetyenziswa emhlabeni, ayilophuculo olungafanelekanga. Abaqhubi kufuneka baqwalasele ukuthengiselana okuthile kokusebenza ngobubanzi obugqithisileyo be-LGP. Umzekelo, ngelixa amandla okuqhekeka kwebhakethi ye-hydraulic elinganisiweyo yomatshini ehlala iyinto emiselweyo, iindlela ezibanzi zinokunciphisa ukutsala okusebenzayo okanye ukubamba okutyhalwayo ngexesha lomjikelo wokumba. Ukongeza, ububanzi obugqithisileyo be-LGP bunokunciphisa uzinzo lwethambeka elisecaleni kwaye bonyuse umngcipheko wokujika, nto leyo ebaluleke kakhulu kukhuseleko lwabaqhubi abasebenza kumhlaba ongalinganiyo. Imiqathango yobubanzi bothutho kwiitreyila (edla ngokugqunywa kwi-80 ukuya kwi-84 intshi ngaphandle kweemvume ezikhethekileyo) kunye nokuphazamiseka okunokwenzeka kwefreyimu kufuneka kuqwalaselwe ngaphambi kokuphucula.

Ngaphezu koko, ukuguquguquka kwerabha kunye nokungabikho kwesiseko sentsimbi eqinileyo kuvumela umzila ukuba ujikeleze ngokuchanekileyo kwindawo engalinganiyo. Xa idibene nokumiswa okukhethekileyo kwesithuthi esingaphantsi komhlaba, oku kuguquguquka kuqinisekisa ukuba umphezulu womzila uhlala udibene nomhlaba, kuthintela umthwalo wenqaku loxinzelelo oluphezulu (olunokudlula i-6.0 psi kwiindlela eziqhelekileyo) eziqhele ukuqhekeza umhlaba ongaphezulu obuthathaka okanye oqhekeke kwiingqukuva ezincinci zodaka.

Iimeko Zokusebenza Ezifuna Uxinzelelo Lomhlaba Ophantsi

Ulwakhiwo lwendlela ye-LGP luchazwa ikakhulu xa iimeko zokusebenza zithintela ngokungqongqo ukuphazamiseka komphezulu okanye zifuna ukutsalwa kakhulu kwiindawo ezixineneyo. Ulawulo lwe-turf, ukwakhiwa kwebala legalufa, kunye nokulungiswa kwegadi yezindlu kufuna ukuba oomatshini bahambe kwiingca ezimiselweyo ngaphandle kokukrazula iindawo ezingcambu. Kwezi zicelo, ukugcina uxinzelelo lomhlaba luncitshisiwe kuthintela ukuxinana komhlaba okungenakuguqulwa. Ngokwahlukileyo koko, kubalulekile ukuqaphela ukuba ezi zinto zisebenza ngerabha kuphela kwayeiingoma ze-fiber ASVngokubanzi azifanelekanga kangako kuneendlela zentsimbi zokudiliza okanye iindawo ezirhabaxa kakhulu, ezinamatye, apho umngcipheko wokuqhawula iintambo ezidityanisiweyo uyanda, nto leyo enokunciphisa ubomi bendlela obuqhelekileyo beeyure ezili-1,000 ukuya kwezili-1,500 ngama-30% ukuya kuma-50%.

Ukongeza, le mizila isebenza kakhulu kumahlathi, kwiindawo ezinamahlathi, nakwimisebenzi yokucoca ikhephu. Kwindawo ezele ludaka okanye ikhephu elinzulu, imizila enoxinzelelo lomhlaba oluphezulu (ngesiqhelo i-5.0+ psi) idla ngokumba iye ezantsi, nto leyo enokubangela ukuba umatshini uphakame embindini wayo. Uyilo lwe-LGP lutshintsha indlela esebenza ngayo umatshini ukusuka ekumbeni uye ekuntanteni phezu komhlaba othambileyo, ukuqinisekisa ukuba uyaqhubeka nokuqhubela phambili kwiindawo ezinzima.

Umzekelo, xa uthenga kubathengisi abathengisa emva kwemarikeIingoma ze-ASV, abaphathi bezixhobo kufuneka balinganise iindleko zokuthenga kwangaphambili kunye neeyure zomjikelo wobomi eziqikelelweyo (ngokuqhelekileyo iiyure ezili-1,000 ukuya kwezingama-2,000 kuxhomekeke kwisicelo), ukuqinisekisa ukuba indlela ekhethiweyo ihambelana ngokugqibeleleyo nendawo yokusebenza ephambili yomatshini.

Iinkcukacha eziphambili: Uxinzelelo, Ukunyathela, Ukuqina, kunye nokulingana

Ukuze wenze izigqibo zokuthenga ezinolwazi, vavanya iinkcukacha ezine ezibalulekileyo: iimilinganiselo zoxinzelelo lomhlaba, ipateni yokunyathela, ukuqina kwesakhiwo, kunye nokunyamezela ukulingana okuchanekileyo. Ubunzulu bokunyathela buchaphazela ngokuthe ngqo ukubambelela kunye nokuphazamiseka kwetyani; ipateni yebhloko engaphantsi (ngesiqhelo i-15-20mm ubunzulu) inciphisa ukukrazula kwityani ebuthathaka, ngelixa ipateni yebha enzulu (25-35mm ubunzulu) inceda kakhulu ekubambeni kwidaka elinzulu.

Ngenxa yokuba uxinzelelo lomhlaba luxhomekeke ngokupheleleyo kubunzima bokusebenza komatshini, abaphathi bezixhobo kufuneka bajonge idatha ethile yemodeli endaweni yokuxhomekeka kwiziseko zendalo yonke. Apha ngezantsi kukho uthelekiso olubonisa indlela uqwalaselo lwethrekhi olutshintsha ngayo iimetrikhi zomatshini othile we-8,000-lb:

Ukufaneleka kwayo kubaluleke kakhulu. I-geometry ye-drive lug kufuneka ihambelane ngokugqibeleleyo nee-sprocket rollers zomatshini ukuthintela ukuphazamiseka kwendlela kunye nokunciphisa ukuguguleka okubangelwa kukungqubana. Abathengi kufuneka baqinisekise ukuhambelana okuchanekileyo kochungechunge lwemodeli ye-ASV kunye nonyaka wemveliso ngaphambi kokufakwa, njengoko i-geometry ye-track lug kunye nokunyamezelana kwe-undercarriage kwahluka kakhulu kwizizukulwana zoomatshini.

Iingoma ze-Aftermarket vs. ze-OEM ASV

Ingxoxo phakathi kwe-aftermarket kunye ne-Original Equipment Manufacturer (OEM) idla ngokuyalela uhlahlo-lwabiwo mali lokugcinwa.Iingoma ze-OEMZenzelwe ukunyamezelana okuchanekileyo kwesithuthi sangaphantsi kwefektri, ziqinisekisa ukuhlanganiswa okungenamthungo kunye namazinga okuguguleka anokuqikelelwa. Nangona kunjalo, ukhetho lwe-premium aftermarket luye lwaphucuka kakhulu kwiminyaka elishumi edlulileyo.
