Ithrekhi yerabha iyingxenye yokuhamba efana ne-crawler enenani elithile lezintambo zensimbi nensimbi ezifakwe ebhandeni lerabha.

Amathrekhi enjoloba alulabanezinzuzo ezilandelayo:
(1) Ukushesha
(2) Umsindo ophansi
(3) Ukudlidliza okuncane
(4) Amandla amakhulu okudonsa
(5) Umonakalo omncane ebusweni bomgwaqo
(6) Ukucindezela okuncane komhlabathi
(7) Umzimba ulula ngesisindo

1. Ukulungiswa kokucindezeleka

(1) Ukulungiswa kokucindezeleka kunethonya elikhulu empilweni yenkonzoithrekhi yerabha yaseShayinas. Ngokuvamile, abakhiqizi bemishini bazobonisa indlela yokulungisa emiyalweni yabo. Isithombe esingezansi singasetshenziswa njengereferensi evamile.

(2) Amandla okucindezela akhululekile kakhulu, okuholela ku: [A] ukwahlukana . [B] Isondo eliphethe umthwalo eliyisondo eliqondisayo lihamba emazinyweni. Ezimweni ezimbi kakhulu, i-pulley esekelayo kanye nepuleti lemoto kuzoklwejwa, okubangela ukuba insimbi eyinhloko iwe. Uma ugibela igiya, ukucindezeleka kwendawo kuphakeme kakhulu futhi intambo yensimbi iyaphuka. [C] Into eqinile iyalunywa phakathi kwesondo lokushayela kanye nesondo eliqondisayo, futhi intambo yensimbi iyaphuka.

(3) Uma amandla okucindezela eqine kakhulu, ithrekhi izokhiqiza ukucindezeleka okukhulu kakhulu, okuholela ekunwebekeni, ekushintsheni kwephimbo, kanye nokucindezela okuphezulu kobuso ezindaweni ezithile, okubangela ukuguguleka okungavamile kwensimbi eyinhloko kanye nesondo lokushayela. Ezimweni ezimbi kakhulu, insimbi eyinhloko izophuka noma ixhunywe yizinjini ezigugile.

2. Ukukhetha indawo yokusebenza

(1) Izinga lokushisa lokusebenza kwemizila yerabha ngokuvamile liphakathi kuka--25 no-+55°C.

(2) Amakhemikhali, uwoyela wenjini, kanye nosawoti ovela emanzini olwandle kuzosheshisa ukuguga komzila. Umzila kumele uhlanzwe ngemva kokusetshenziswa endaweni enjalo.

(3) Izindawo zomgwaqo ezinezimbobo ezibukhali (njengezinsimbi, amatshe, njll.) zingabangela ukulimalaithrekhi yerabha.

(4) Amaphethelo omgwaqo, imisele noma umgwaqo ongalingani kuzobangela imifantu ephethini yokunyathela ohlangothini lomhlabathi lomphetho wethrekhi. Intambo yensimbi ingaqhubeka isetshenziswa uma imifantu enjalo ingalimazi intambo yensimbi.

(5) Imigwaqo yamatshe namatshe izobangela ukuguguleka kwasekuqaleni kwendawo yerabha uma ithintana namasondo athwala imithwalo, kwenze imifantu emincane. Ezimweni ezimbi kakhulu, umswakama uyangena, okubangela ukuba insimbi eyinhloko iwe futhi ucingo lwensimbi luphuke.
