Nubuhe buryo butatu aribwo buhanga cyane mubucukuzi bwa parikingi?

A.

Ukuboko gushyizwe kuri perpendikulari hasi kuri dogere 90, naho inyuma yindobo isukuye hasi. Buri silinderi iri muburyo butagira igitutu, kandi nta cyangiritse kashe ya peteroli. Ariko, iyi myanya irashobora gutuma indobo ya silinderi yaguka. Kubwibyo, mubikorwa bifatika, kugirango birinde impanuka, abantu benshi bakuramo silinderi yindobo bakemerera indobo kuruhukira hasi.

B.

Iyo ihagaritswe muri ubu buryo, kashe ya peteroli ya silinderi iba ihangayitse kandi silinderi iragaragara, kubwibyo ntibikunze kugaragara kurubuga rwakazi. Nyamara, ubu ni bwo buryo bwo guhagarara umwanya munini mugihe cyo gutwara ibicuruzwa. Ubu bwoko bwa parikingi bugabanya uburebure n'uburebure bwa excavator, bigatuma byoroha cyane gupakira ku gikamyo kibase nta burebure cyangwa burebure.

C.

Iyo ihagaritswe muri ubu buryo, silinderi zose zamavuta ziba zasubiye inyuma, zifasha kurinda silinderi yamavuta kandi bikanoroha kugenzura amavuta ya hydraulic mbere yo gutangira akazi bukeye.

Nubuhe buryo butatu aribwo buhanga cyane mu gucukura parikingi?
