Ivili lokuqhuba liyashukuma xa iHowo 7 Dump Truck ihamba, isiphelo sangaphambili sijiwuzisa ngapha nangapha kwinqwelo-moya enqamlezileyo, kwaye ukuqhuba akuzinza.Ezona zizathu ziphambili zoku zezi:
(1) ukungahambi kakuhle kwevili lokuqhuba;
2) Ukubekwa ngendlela engafanelekanga kwevili langaphambili;
(3) Isixa esikhulu sokuphambuka kwevili;
4) Uphazamiseko lwentshukumo yendlela yothumelo;
5) i-axle kunye nefreyim deformation;
6) ukuqina kokungalingani kokumiswa kwesobunxele nasekunene, ukungaphumeleli kwe-absorber, ukungaphumeleli kwesikhokelo, njl.
Uxilongo kunye nokungabandakanywa:
I-1) Ukuhlolwa kokubonakala: khangela ukuba ukuhluleka kwe-shock absorber, ukuba ukuvuza kweoli okanye ukungaphumeleli, kufuneka kuthathelwe indawo;khangela ukuba imithombo yokumisa ekhohlo nasekunene iphukile okanye ayilingani, ukuba kukho ukutshintshwa kwemithombo yokumisa;jonga ukuba ngaba udibaniso lwemithombo yokunqunyanyiswa lukhululekile, indlela yokuhambisa intambo ayinasiphazamiso sokushukuma, ukuba kukho nayiphi na into ekufuneka ikhutshelwe ngaphandle;
(2) xhasa icala le-asi ephakathi kunye nangasemva, amavili angaphambili aneepadi zokhuni zomqamelo, qala injini kwaye ngokuthe ngcembe wenze isithuthi kwigiya enesantya esiphezulu, ukuze i-asi yokuqhuba ifikelele kwisantya sokungcangcazela komzimba. .Ukuba umzimba kunye nokungcangcazela kwevili lokuqhuba, kubangelwa yinkqubo yothumelo.
(3) khangela ukuba amavili angaphambili anamacala na: xhasa iasi engaphambili, beka inaliti yokukrwela kumphetho ongaphambili, jija ivili ngokucothayo, jonga ukuba udini lulukhulu kakhulu kusini na, ukuba kunjalo, kufuneka kufakwe omnye umva omnye;
(4) Susa ivili langaphambili, khangela ibhalansi eguquguqukayo yevili langaphambili kwi-balancer eguqukayo, kwaye ufake ibhloko yokulinganisa ngokomlinganiselo wokungalingani;
(5) Ukuba ezi zitshekisho zingentla ziqhelekile, jonga isakhelo, i-axle deformation, kunye nesixhobo sokulungelelaniswa kwevili langaphambili ukujonga nokulungelelanisa ulungelelwaniso lwevili langaphambili.
