Kugirango uhindure umuyoboro wa dogere 90 hanyuma uhindure icyerekezo cyamazi yatemba, icyuma cyoroshye 90 ° inkokora kumuhanda gikoreshwa muguhuza imiyoboro ibiri ukoresheje guhuza umugozi wumugabo numugore.
Ihuza iyo ibice byimbere ninyuma byahujwe hamwe kandi bigahuzwa.
300 Ibyiciro byabanyamerika Bisanzwe Byuma Byuma Byuma 90 ° Inkokora yo mumuhanda ifite ibintu byinshi byiza cyane nko kurwanya ubushyuhe bwinshi, kurwanya sulfure no kurwanya ruswa.Barashobora kwihanganira umuvuduko mwinshi nubushyuhe buke kandi nibicuruzwa bikomeye kandi biramba.Mubyongeyeho, izi nkokora zo mumuhanda 90 ° zirashobora gukoreshwa mumasoko atandukanye yinganda kugirango uhuze imiyoboro yamazi cyangwa imiyoboro yumuyaga.Bafite kandi inyungu zo kugabanya ibimeneka kandi byoroshye gushiraho no gukoresha.300 Ibyiciro byabanyamerika Bisanzwe Byoroheje Byuma Byuma 90 ° Inkokora yo mumuhanda ifite umwanya wingenzi kumasoko.Ifite ibipfunyika byigenga nibikorwa byiza byo gufunga, kandi ibintu byayobye ntabwo byoroshye kugira ingaruka kumiterere yimbere yimbere, ibyo bigatuma ibicuruzwa bigira igihe kirekire cyo kubika, igiciro gito kandi kiramba Byongeye, ubunini busanzwe bwa dogere 90 ya Street Elboe ni ugereranije umubyimba, kandi iyo diameter yumusozi muto wizenguruko irenze 20mm, irashobora guhura cyane nabantu basabwa kugirango berekane inkokora ihuza.
