Njengethuluzi elivamile empilweni yomuntu, ama-wheelbarrow asinika ukulula nokusebenza kahle. Eqinisweni, sizothola ukuthi amasondo enqola akhiwe ngamasethi amabili amasondo aqondisayo nahambayo, ngakho-ke lawa amabili kufanele asatshalaliswe kanjani?
Ngokuvamile, kunengqondo kakhulu ukuhlela i-flatbed trolley enamasondo aqondisayo ngaphambili kanye namasondo ajwayelekile ngemuva. Isondo elingemuva elijwayelekile lilawula kakhulu isiqondiso futhi lidinga i-torque encane uma lishintsha isiqondiso. Ngakho-ke, ligcina amandla uma lijika. Ingaphambili liyisondo eliqondisayo, uma uhamba umugqa oqondile, ukulawula ingalo ukulungisa isiqondiso kudinga amandla amancane. Uma ujika, kuyaguquguquka kakhudlwana. Ngokuvamile, isondo elijwayelekile kanye nesondo eliqondisayo uma kusetshenziswa inqola ejwayelekile amasondo amabili angaphambili aqondisayo, isondo elingemuva eliyi-universal, lapho inqola idinga ukujika, ingemuva lesondo eliyi-universal eline-thrust, lizosunduza ingaphambili lamasondo amabili asezingeni ukuze lijike ndawonye, ukuze kuqedwe inkinga yokuqondisa inqola.
Ngaphandle kokuthi kunezidingo ezikhethekile zokusetshenziswa kwendawo ezungezile. Kuma-stroller ezingane, uzothola ukuthi amasondo e-universal angaphambili, lokhu kungenxa yokuthi, lolu hlobo lwe-stroller ngokuvamile luyi-forward force, aluvamile ukudonsa emuva. Ama-stroller ezingane kufanele adlale indima ekwenzeni kube lula ukuqondisa, ngakho-ke afakwa ngaphambili. Kodwa afakwe ngaphambili, kodwa futhi kaningi ngenxa yesizathu sokusunduza, ingaphambili lesiteringi sesondo se-universal alisebenzi kahle. Into enhle ukuthi i-stroller incane futhi kulula ukuyilawula.
