Ni ubuhe burebure bw'ikiraro cya crane?

Bridge cranes are the most commonly used lifting equipment in workshop. The span of a bridge crane refers to the distance between the centerlines of the two rails on its running track. It is demarked as: L. The unit is usually M (meter).

Uburebure bwa crane y'ikiraro bufitanye isano itaziguye n'uburebure bwa girder yayo nyamukuru kandi bigira ingaruka ku gishushanyo mbonera cya girder y'ibanze. Kubwibyo, ni igipimo cyingenzi. Niba inyubako y'uruganda rw'umukoresha yubatswe mu cyuma, isosiyete yo gushushanya izaba yamaze gutegura imizigo ya crane, inzira za gariyamoshi, n'ibindi bice. Umukoresha arashobora kumenya uburebure bwa crane yikiraro hashingiwe ku intera yo hagati hagati hagati hagati ya gari ya moshi ebyiri.

Ku bikoresho byasubiwemo hamwe n'inyubako za beto zishaje zisaba gushiraho imizigo itwara imizigo na rails ku mpera za gable, intera yo hagati ya inzira igira ingaruka zikomeye n'ubugari bw'inyubako. Kugirango ushyireho neza no gukora neza kwa crane y'ikiraro, uruhushya rwa santimetero 25 rugomba kugumana hagati ya crane y'ikiraro kimwe n'umupaka w'inyubako. Kuri cranes z'ikiraro cya kabiri cya girder, uruhushya rwa cm 40 rurakenewe. Abakoresha barashobora gukoresha uru ruhushya kugirango bashyireho imizigo itwara imizigo na gariyamoshi, hamwe no kubara uburebure bwa crane yikiraro.

Isano hagati ya Crane Span na Building Span (ubugari) bw'inyubako y'icyuma hamwe n'uburebure bwa crane y'ikiraro ni ibitekerezo bitandukanye. Ubugari bw'inyubako y'inyubako y'icyuma ni ikintu cy'ingenzi kigira ingaruka kuri crane span. Muri rusange, kumenya uburebure bw'ubwubatsi bifasha kubara uburebure bwa crane girder. Uburyo bwo kubara uburebure bwubwubatsi hamwe na crane span ni ibi bikurikira:

Lo = Lk + 2s, aho Lo ari uburebure bwa atelier, Lk ni ikiraro cya crane span, na S ni intera iri hagati ya bridge crane beam axis na axis ya atelier. Ku bigo by'ubucuruzi biciriritse, S ubusanzwe ni 0.75m. Urugero (igisubizo cy'ibisobanuro gusa): Niba crane ya toni 10 ifite uburebure bwa 16.5m itangwa, uburebure bwawe bw'atelier bugomba kuba 18m, hamwe na axis y'atelier ihujwe n'umupaka wo hanze w'inkingi. Niba crane ya toni 50 ifite uburebure bwa 22.5m itangwa, hitamo uburebure bw'inyubako ya 24m. Muri iki kibazo, kwagura umupaka wo hanze w'inkingi 250mm kurenga axis y'ubwubatsi birakwiriye (kuko toni nini ya crane ikeneye igice kinini cy'umusaraba wa colonne, bishobora gutuma uruhushya rwa 750mm rudahagije mu gushiraho igiti cya crane).

Mugihe cyo kubara uburebure bwa crane ya bridge, dukunze kuvuga intera yimbere hagati y'inkingi za nyuma mu nyubako (ni ukuvuga ubugari bw'imbere bw'inyubako). Gukuramo cm 50 kuri iyi intera y'imbere bitanga uburebure bwa crane imwe. Gukuramo cm 80 bitanga uburebure bwa crane ya girder ebyiri. Iyi span ibarirwa ihuye cyane n'uburebure nyabwo. Iyo abakiriya batumiza ibicuruzwa, dutanga igishushanyo kirambuye cyamakuru kugirango twemeze uburebure nyabwo.
