Yateguwe kandi itejwe imbere na sosiyete yacu bwite, Umuyoboro wa hydraulic umurongo uvuga Trolley ni sisitemu nziza yo kumurongo wa gari ya moshi na trafrel. Bitewe n'amashanyarazi, birashobora kwimuka no kugenda ubwabyo, hamwe na hydraulic silinderi na screw jack ikoreshwa mumwanya no kugarura imiterere. Trolley ifite ibyiza byinshi mubikorwa, nkigiciro gito, imiterere yizewe, imikorere yoroshye, umuvuduko wihuse hamwe na tunnel nziza.
Trolley muri rusange yakozwe nkubwoko bwa arch, ukoresheje icyitegererezo cyicyuma, nta kugenda mu buryo bwikora, ukoresheje imbaraga zo hanze kugirango ukurure, kandi icyitegererezo cyo kugurisha kirakorerwa intoki, kikaba kirimo akazi. Ubu bwoko bwo kumurongo muri Trolley bukoreshwa mubwubatsi bugufi bwa tunnel, cyane cyane kubijyanye nubwubatsi hamwe nindege igoye hamwe na geometrie yo mu kirere, guhinduka kenshi. Ibyiza byayo biragaragara. Umuyoboro wa kabiri ushimangira ko hashimangiwe kumurongo woroshye ushushanya igishushanyo mbonera, kandi icyarimwe, igiciro cyubwubatsi ni gito. Ibyinshi mubikorikori byoroshye bikoresha isuku ya artificial, kandi troley yoroheje yuzuye yuzuye amakamyo atanga amakamyo atanga amakamyo, niko gukomera kwa Trolley bigomba gukomera cyane. Bamwe mu banyamerika boroheje bakoresha kandi ibyuma by'imiterere, ariko baracyakoresha inkoni ya dread kandi ntibahinduke mu buryo bwikora. Ubu bwoko bwa Trolley muri rusange bwuzuyemo amakamyo ya pompe. Trolleys yoroshye trolleys muri rusange ikoresha ibyuma bihujwe. Ihuriro ryimikorere ikozwe muri rusange ikozwe mu masahani yoroshye.
Gukomera kwicyuma bigomba gusuzumwa muburyo bwo gushushanya, bityo intera iri hagati yicyuma ntigomba kuba nini cyane. Niba uburebure bwicyuma ni 1.5m, impuzandengo ya spacing hagati yicyuma ntigomba kurenza 0.75m, hamwe nimpapuro ndende, hamwe nimpapuro zimaze igihe zigomba gushyirwaho hagati yo gusunika no koresha kugirango byoroherezwe n'imikorere. Niba pompe ikoreshwa mugushime, umuvuduko wa infucsi ntugomba kwihuta cyane, bitabaye ibyo bizatera imyumbati yimiterere ya 500mm, umuvuduko wa infusic ukwiye gutinda. Witondere mugihe wangiritse no gusuka. Witondere gusuka beto igihe cyose kugirango wirinde gusuka beto nyuma yo kuzuza, bitabaye ibyo bizatera ibisasu cyangwa guhindura Trolley.
