Ubude obupheleleko budinga ukuhleleka okufaneleko
Irhelo elifitjhani lobude encwadini litjhiya umehluko wokuhleleka kwama-ekseli, amabhasi nomkhawulo wethreyila we-12,000 kg ngqo. Umthetholawulo 221 unikela umehluko ongenzasi. Hlola bona induku yokudonsa namkha isihlanganisi sibalwa na; sebenzisa ukuhleleka kwangempela kunegama elijayelekileko elithi “ithreyila”.
Ithreyila eline-ekseli yinye namkha iyunithi yinye yama-ekseli, ngaphandle kwe-semi-trailer, lilinganiselwa ku-8 m kungafakwa induku/isihlanganisi lapho i-GVM yalo ingadluli ku-12,000 kg, naku-11.3 m lapho idlula ku-12,000 kg. Elinye ithreyila elingasiyo i-semi-trailer elingaphezu kwe-12,000 kg lilinganiselwa ku-12.5 m kungafakwa induku/isihlanganisi. Ikoloyi ehlangeneko namkha inhlanganisela yekoloyi edonsako ne-semi-trailer ilinganiselwa ku-18.5 m kufakwe isihlanganisi.
Eminye imikhawulo etjhiwo yi-22 m yesitimela samabhasi, 26 m yesitimela samabhasi sezokuthutha msinyana esibekiweko, 15 m yebhasi, 12.5 m yezinye iinkoloyi ngaphandle kwama-semi-trailer, ne-22 m yezinye iinhlanganisela. Umkhawulo wenhlanganisela wokugcina awufaki ikoloyi yokutakula lapho idonsako. Ithreyila elihlanganiswe ngesihlanganisi esingajikiko linomkhawulo walo we-1.8 m kufakwe isihlanganisi.
Umthetholawulo awubali iintlabagelo ezifaneleko zokuvikela ngaphambili ezandisa ubude ngokungadluli ku-300 mm; ibhampa yomenzi ayisikho okungabalwako. Amalungiselelo la awesuli umkhawulo ophasi otjengiswe endleleni namkha avumele ipahla ede ngokweqileko.
Itshwayo lomkhawulo wobude elitjengisiweko lingavimbela ikoloyi efitjhani kunomkhawulo ojayelekileko. Funda ubude obutjengisiweko ubuqathanise nokuhleleka kwakho kwangempela okuvunyelweko.
Ukuphakama kufaka ipahla
Ukuphakama okupheleleko, kufakwe nanyana ngimuphi umthwalo, akukafaneli kudlule ku-4.65 m kwebhasi elineentezi ezimbili namkha ku-4.3 m kwenye ikoloyi ngaphasi komthetho ojayelekileko wencwadi. Linganisa ufike engcenyeni ephakeme kunazo zoke ezokukhamba ngempela, kufakwe ipahla namkha iintlabagelo ezithwaliweko.
Ikoloyi engaphasi komkhawulo ojayelekileko isengaba phezulu khulu ebhulohweni namkha ekungeneni okunetshwayo. Yazi ukuphakama kwayo kwangempela ngaphambi kokukhetha indlela. Ungasebenzisi nakanye umkhawulo wekoloyi osemthethweni ukulinganisela isikhala ngaphasi kwesakhiwo.
Ububanzi buya ngohlobo lwekoloyi
Incwadi ivumela ububanzi obupheleleko obungafika ku-2.6 m bebhasi elinemida yesikhungo samathayi wangaphambili ehlukaniswe ngaphezu kwe-1.9 m, nekoloyi yepahla ene-GVM okungenani ye-12,000 kg. Umkhawulo ojayelekileko wezinye iinkoloyi ngu-2.5 m.
Ibanga phakathi kwemida yesikhungo samathayi mbandela wesigaba sebhasi leso, ingasi ububanzi bebhasi. Sebenzisa ihlathululo yobubanzi obupheleleko neentlabagelo ezingabalwako ezibekiweko, bese uhlola imithetho yokuphuma kwepahla ngokwahlukana. Ukuphuma kwesiboniboni okuvunyelweko akuvumeli ipahla ukuphuma ngesilinganiso esifanako.
Isibonelo esihlathululiweko
Ikoloyi elayitjhiweko iphakeme nge-4.1 m, ngaphasi komkhawulo ojayelekileko we-4.3 m. Ibhuloho linetshwayo lomkhawulo wokuphakama we-3.9 m. Ikoloyi ayikavunyelwa ukusebenzisa indlela leyo. Kufanele igcwalise kokubili ukuhambisana nemithetho yekoloyi evamileko nomkhawulo wesakhiwo sendawo.
