Amakamyo asanzwe atwara ubusanzwe atwara metero kibe 10-14 zubutaka bwubutaka iyo yapakiwe kurwego cyangwa gato 'umwirondoro '. Abakoresha barashobora guhindura umutwaro ukurikije ubushuhe bwubutaka; Ubutaka butose, buremereye cyane bisobanura kugabanya umubare wa metero kugirango uburemere bugabanuke kandi bugumane ituze mugihe cyo kuryama.
Amakamyo ya Tri-axle hamwe na super dump yongeramo imitambiko myinshi kugirango ikwirakwize uburemere ahantu hanini, byongera imizigo yemewe nkuko amategeko abigenga abiteganya. Amakamyo azwi cyane naba rwiyemezamirimo bimura ubwinshi bwubutaka, umucanga, cyangwa igiterane buri munsi.
Ukurikije ibisobanuro n'amategeko agenga akarere, amakamyo ya tri-axle cyangwa super dump yamashanyarazi arashobora gutwara mumwanya wa metero kibe 15-25 zubutaka bwubutaka kuri buri mutwaro. Ubushobozi bwiyongereye bugabanya ingendo zimirimo minini, bigatuma biba byiza mugutezimbere kugabana, imishinga minini yubusitani, hamwe nubucuruzi bwinganda cyangwa inganda.
Kwimura amakamyo yimodoka ahuza ikamyo isanzwe yajugunywe hamwe na romoruki itandukanye ishobora gupakirwa hanyuma ikoherezwa mumubiri nyamukuru. Amakamyo ya Semi arangiza, bitandukanye, koresha ibimashini bya romoruki hamwe numubiri muremure wazamutse uva imbere kugirango usohore ibikoresho unyuze inyuma.
Ikamyo yombi yimura amakamyo hamwe na kimwe cya kabiri cyajugunywe birashobora gutwara metero kibe 20-25 zubutaka bwubutaka murugendo rumwe, ukurikije uburebure bwumubiri nuburebure. Zifite akamaro kanini mugutwara intera ndende aho umuhanda ukora neza kuruta gukora cyane, nko gutanga ubutaka hejuru yu mwobo wa kure kugera kumuhanda munini cyangwa ahakorerwa imirimo yinganda.
Nubwo ubutaka bwubutaka bushyirwa muri metero kibe, ubushobozi bwikamyo ita amaherezo igengwa nuburemere. Ikibanza kibisi cyubutaka gishobora gupima hafi ibiro 1.000 na 2500 bitewe nuburyo butose kandi bwuzuye. Ubushuhe buturuka ku mvura cyangwa kuhira birashobora gusunika uburemere bugana ku mpera yo hejuru y’urugero, ibyo bikaba bigira ingaruka zikomeye kuri metero zingahe ikamyo ishobora gutwara.
Amabwiriza menshi yumuhanda rusange ashyiraho agapira kuburemere bwibinyabiziga, bikubiyemo uburemere bwikamyo, lisansi, umushoferi, nu mutwaro hamwe. Niba ikamyo yajugunywe ipima hafi 20.000-25.000 pound yubusa kandi ntarengwa ryemewe ni hafi 80.000 pound, ubwo rero umutwaro ntarengwa ntushobora kurenga hafi 55.000-60.000. Kubutaka bwumutse, bworoshye, bushobora guhindurwa muri metero kibe 14 cyangwa zirenga, mugihe itose cyane, ubutaka buremereye bushobora kugabanya ubushobozi bwumutekano kuri metero kibe 10-12 cyangwa munsi yayo. Abakora umwuga wo gutwara ibintu bahora baringaniza ibyo bintu kugirango bakomeze kubahiriza mugihe bagitanga imitwaro ikora neza.
Gupima uburebure n'ubugari bw'ahantu mu birenge. Hitamo uburyo uburebure bwubutaka bugomba kuba bwimbitse, no mubirenge. Kurugero, ibyatsi bishya birashobora gusaba santimetero 4-6 zubutaka, mugihe ibitanda byubusitani bishobora gukenera santimetero 8-12.
Kugwiza uburebure × ubugari × ubujyakuzimu kugirango ubone metero kibe zose. Noneho gabanya iyo mibare kuri 27 kugirango uhindure kuri metero kibe, kuko ikibanza kimwe kibe kingana na metero kibe 27. Kurugero, niba ubuso bwumushinga bufite metero 60 z'uburebure, metero 30 z'ubugari, kandi bukeneye metero 0,5 (santimetero 6) zubutaka, ingano ni (60 × 30 × 0.5 = 900) metero kibe. Kugabanya 900 kuri 27 bitanga hafi metero kibe 33.3.
Iyo metero kibe zose zimaze kumenyekana, gabanya gusa ubushobozi bwikamyo yatoranijwe. Niba ikamyo isanzwe yajugunywe ifite metero kibe 12, noneho (33.3 ÷ 12 ≈ 2.8), bityo rero harasabwa imitwaro itatu yamakamyo yubutaka. Gukoresha imibare izengurutse hamwe numutekano muke uremeza ko udakora bigufi, bishobora gutinza amanota, gutera, cyangwa akazi ko guhuza.
Tekereza nyirurugo ateganya kongera gutondekanya inyuma yinyuma no gushiraho ibyatsi bishya. Ubuso bupima metero 80 kuri metero 40 kandi bukenera santimetero 4 zubutaka bushya. Guhindura santimetero 4 kubirenge bitanga metero 0.33. Kugwiza 80 × 40 × 0.33 bivamo metero kibe 1.056 zubutaka bukenewe. Kugabanwa na 27 bitanga hafi 39.1 kubik.
Niba uwatanze isoko akoresheje ikamyo nini yo mu bwoko bwajugunywe ifite ubushobozi bwo gutwara metero kibe 10 kuri buri mutwaro, hafi amakamyo ane yohereza amakamyo arakenewe kugira ngo ashobore kuzuza ibisabwa. Niba ikamyo nini ya metero 15 yajugunywe iraboneka kandi irashobora gukoreshwa neza mumuturanyi, imizigo itatu yikamyo ishobora kuba ihagije, hasigara buffer ntoya yo gukemura no gutakaza igihombo.
Ubutaka bwitwara butandukanye cyane iyo butose bwumye. Ubutaka butose butekera cyane kandi buremereye cyane, bivuze ko ikamyo ishobora kumenwa ishobora gutwara metero nkeya murugendo kugirango igume mumurongo nuburemere bukabije. Ubutaka buremereye bwibumba busanzwe bupima ibirenze umusenyi, bikagabanya ubushobozi bwa cubic yard yubushobozi bwikamyo yajugunywe nubwo ingano yumubiri ikomeza kuba imwe.
Uburebure bw'imbere, ubugari, n'uburebure bw'uruhande rw'igitanda cyajugunywe bigena ingano ntarengwa yumubiri. Uburebure bwumubiri bushobora kuva kuri metero 10 kugeza kuri 22 cyangwa zirenga, hamwe nuburebure bwuruhande butuma imibiri itwara munsi ya metero kibe 4 kugeza kuri metero zirenga 30 iyo zuzuye. Nyamara, abashoramari ntibakunze kwishyiriraho igipimo ntarengwa cya geometrike kuko bagomba gukomeza gutekereza kuburemere bwibintu biranga guta neza.
Amategeko y’imihanda yo mu karere no mu gihugu ashyiraho amahame akomeye yipakurura imitwaro, uburemere bwimodoka, ndetse rimwe na rimwe ubwoko bwibintu. Ku biraro cyangwa umuhanda wa kabiri, imipaka yigihe gito cyangwa ihoraho irashobora gukoreshwa, guhatira abashoferi batwara amakamyo kugabanya yardage kuri buri mutwaro. Ubutaka no kugera nabyo bifite akamaro: kubutaka bworoshye, ahantu hahanamye, cyangwa guhindagurika cyane, abashoferi barashobora guhitamo imitwaro yoroshye kugirango barusheho gukurura, gufata feri, no gutuza mugihe bazamuye umubiri wajugunywe.
