11. Umwanzuro
Imashini zicukura Liebherr R974, R974B, R974C, na R974C Litronic HD ni zo zigaragaza ubuhanga bwo mu Budage mu rwego rwo hejuru mu bucukuzi bw’amabuye y’agaciro. Izi mashini za toni 80–90 zikoreshwa mu bucukuzi bukomeye ku isi, aho kwizerwa no kuramba bigira ingaruka zitaziguye ku nyungu z’umusaruro.
Itsinda ry'amapine y'umuziba w'inzira (5000127 / 7365656) ni igice cy'ingenzi kiyobora umuyoboro w'inzira wa mm 260, gicunga umuvuduko w'inzira, kandi kikigarurira imitwaro y'ingaruka mu gihe gishyigikira igice kinini cy'uburemere bw'imashini. Ubuhanga bw'imashini ikora nk'iy'umuziba—ifite uburyo bwo gukomeretsa cyane (ubujyakuzimu bwa mm 8–12), sisitemu yo gufunga neza, hamwe n'ubwubatsi bw'icyuma gikomeye—byumwihariko byakozwe neza kugira ngo bigerweho n'ibikenewe cyane mu bucukuzi bw'amabuye y'agaciro.
CQC TRACK (HELI) ni uruganda rw’ibice by’imodoka biremereye bya EXC crawler rufite ubushobozi bwo gukora ibice biremereye, rufite uburyo bwo guhuza ibintu byose, ubuhanga buhanitse mu byuma, uburyo bwo kugenzura ubuziranenge, hamwe n’ibikorwaremezo byuzuye by’uruhererekane rw’ibikoresho ku isi. Ibice byacu byakozwe kugira ngo bihuze cyangwa birenge ibisabwa na Liebherr OEM, birimo:
- Gucura ibyuma bifunze kugira ngo imiterere y'ibinyampeke ibe myiza kandi birwanye umunaniro
- Uburyo bwo kuvura ubushyuhe bugizwe n'ibikoresho bibiri bivanze igice gikomeye cy'imbere (280–350 HB) n'ubuso bukomeye bwo kwangirika (HRC 50–58)
- Gukomera cyane mu buryo bwimbitse hamwe n'ubujyakuzimu bwa mm 8–12 kugira ngo ubucukuzi bukomeze kumara igihe kirekire
- Gutunganya neza hakoreshejwe ubushobozi bwa ± 0.02 mm bwo kwihanganira ibintu ku buryo bw'ingenzi
- Uburyo bwo gufunga ibintu byinshi mu buryo bwo kwirinda ibintu bihumanya mu turere dukomeye
- Gukurikirana ibintu byose hamwe na raporo z'ibizamini bya Mill na icyemezo
Iri shoramari mu by’ubwubatsi ritanga umusaruro wizewe mu bikorwa bikomeye ku isi—kuva mu birombe by’amabuye y’agaciro byo muri Ositaraliya na Amerika y’Epfo kugeza ku bikorwa bya diyama na zahabu byo muri Afurika, kuva mu turere tw’Uburusiya dukonja kugeza ku mabuye y’agaciro yo muri Koreya, no kuva ku mucanga wa peteroli wo muri Kanada kugeza ku bikorwa by’ubucukuzi bw’amabuye y’agaciro byo mu Burasirazuba bwo Hagati no mu Burayi.
Ku bijyanye n'ibisobanuro bya tekiniki, ibibazo ku biciro, cyangwa gutanga amabwiriza y'ibice by'imodoka biri munsi y'uruhererekane rwa Liebherr R974, hamagara ishami mpuzamahanga rishinzwe ubucuruzi rya CQC TRACK kugira ngo umenyeshe nimero y'uruhererekane rw'imashini yawe n'ibisabwa byihariye.
