Ithrekhi yerabhaluhlobo olubalulekileyo lwe-crawler, inokumelana nokuguguleka okukhulu, ukumelana nokuchaphazeleka kwaye ayinamanzi, kwaye isetyenziswa kakhulu kwimishini yezolimo, kwimishini yokwakha nakwezinye iindawo.
Imizila yerabha, eyaziwa ngokuba ngamatayara erabha, luhlobo lweemveliso zerabha. Imizila yerabha yenziwe ngezinto zesinyithi, umphezulu wayo ugqunywe ngumaleko omncinci werabha. Ngexesha lokusetyenziswa, xa idibana nomhlaba, irabha inokufunxa ngempumelelo amandla ombane aziswa ngumhlaba kwaye inciphise ukuguguleka kwawo. Ukongeza, imizila yerabha inomngquzulwano omkhulu nomhlaba, okwenza kube lula ukusebenza phantsi kweemeko ezinzima.

Intshayelelo emfutshane

Imizila yerabha yenziwe ngerabha kunye nocingo, ngokuqhelekileyo intsimbi, i-aluminium, kunye nezinye iintsimbi. Inokumelana nokuguguleka okuhle ngexesha lokusetyenziswa kwaye inokumelana ngcono nemithwalo yokutshayiswa kunye nokungqubana komhlaba. Ukongeza, inxalenye yemizila yerabha edibana nomhlaba inokusebenza okuthile okungangeni manzi, okunokuqinisekisa ngcono uzinzo lwayo lokusebenza.
Ngenxa yokumelana nokuguguleka okunamandla, ukumelana nokuchaphazeleka kunye nokumelana nokungangeni manzi kwemizila yerabha, ubomi bayo bokusebenza bude ngexesha lokusetyenziswa. Ukongeza, imizila yerabha ikwanazo neendlela ezithile zokufunxa ukutshayiswa, ezinokunciphisa ngempumelelo impembelelo kunye nokuguguleka komhlaba koomatshini nakwizixhobo. Ngenxa yokuba imizila yerabha inezi mpawu zibalaseleyo, ikwasetyenziswa kakhulu koomatshini bezolimo, iinqanawa kunye nezinye iindawo. Ngokwedatha efanelekileyo, ibandakanya ngaphezulu kwama-70% kwicandelo loomatshini bezolimo.

Ukusebenza

Itreyi yerabha yimveliso ekwaziyo ukumelana nokuguguleka, amanzi angangeni, ikwaziyo ukumelana noxinzelelo kwaye ayichaphazeleki. Ikwaziyo ukumelana nokugqwala kakuhle kunye nokumelana neoyile. Ukongeza, itreyi yerabha inokuguquguquka okuhle kunye nokuguquguquka okuhle. Akulula ukuyiguqula kwaye inokugcina indawo yomatshini kakuhle ngexesha lomsebenzi, ukuze isebenze kakuhle.
Imizila yerabha yenziwe ngezinto ezikhethekileyo ezinokumelana nokuguguleka okuhle kunye nokumelana nempembelelo, kwaye zinokumelana noxinzelelo oluphezulu. Kwimishini yezolimo, oomatshini bokwakha kunye nezinye iindawo, imizila yerabha isetyenziswa kakhulu kwiindawo ezahlukeneyo zokusebenza, kodwa ubomi bayo benkonzo bumalunga neminyaka eli-10-15. Ke ngoko, imizila yerabha inamathuba amahle ophuhliso kunye nendawo yemarike.

Imiba ekufuneka iqwalaselwe xa kuthengwa iitrekhi zerabha

1. Nceda uthenge iimveliso eziqinisekisiweyo ngomgangatho ukuqinisekisa umgangatho kunye nobomi benkonzo.
2. Nceda uthenge iimveliso eziveliswe ngamashishini akumgangatho ophezulu wobugcisa ukuqinisekisa umgangatho.
3. Nceda uthenge inkonzo emva kokuthengisa imveliso ukuqinisekisa ukuba akuyi kubakho ngxaki zomgangatho ngexesha lokusetyenziswa kwayo.
4. Xa uthenga, nceda ukhethe umenzi onomlinganiselo omkhulu, kwaye uqaphele ukuba umenzi lishishini eligxile ekuveliseni iingoma zerabha.
