Ku bibuga by'imizigo bya gari ya moshi, ibibanza by'ubwubatsi, n'imbuga z'ubwubatsi bwa gari ya moshi, cranes za gantry zikora nk'ibikoresho by'ingenzi byo gupakira no gupakira, bigira ingaruka ku mikorere n'umutekano.

Ibikoresho byose byo kuzamura ku muhanda wa gari ya moshi wa Mombasa-Nairobi wa kilometero 480 muri Kenya bikoresha ibicuruzwa bya Henan Mine Crane. Zagenewe ibidukikije bigoye byo ku nkombe hamwe n'umuyaga mwinshi n'imvura nyinshi, izi cranes za gantry zigezweho zitanga ibikorwa byihariye byo kuzamura no gukora neza, bitanga icyizere cy'ibanze cy'imikorere ya gari ya moshi. Guhitamo cranes za gantry ku nganda za gari ya moshi bisaba gusuzuma byimbitse ibisabwa mu mikorere, ibidukikije n'ibisobanuro bya tekiniki. Hano hasi hari ubuyobozi bw'imyitozo ngororamubiri.

Lifting capacity is the primary selection criterion, determined by the maximum load to be handled, usually with a 20% margin for unexpected conditions. Sitasiyo z'imizigo ya gari ya moshi zikenera ibikoresho bya toni 50-120 zo gutwara kontineri, mu gihe gushyirwaho kwa precast beam mugihe cyo kubaka gari ya moshi bisaba ubushobozi bwo kuzamura hejuru. Kontineri ya Henan Mine ya gari ya moshi ya Mombasa-Nairobi ihuye neza n'ibisabwa muri Afurika.

Igishushanyo mbonera kigomba guhuza nuburyo bwo kugenzura ibicuruzwa. Amabwiriza rusange ni uko cranes za gantry zifite uburebure buri munsi ya metero 35 no kuzamura ubushobozi munsi ya toni 50. Ku birenge byagutse bya gantry, umuvuduko mwinshi wo gukora, cyangwa gufata kenshi ibice birebire, biremereye, cranes za gantry ebyiri zigomba gutorwa. Ibipimo bya wheelbase bigomba kuzuza ibisabwa by'umutekano, akenshi kuva kuri 1/4 kugeza kuri 1/6 y'uburebure bw'uburebure, mugihe bemeza ko imizigo ishobora kunyura neza mu cyuma cy'icyuma cy'ukuguru gushyigikiwe.

Guhitamo abakozi ni ingenzi. For high-frequency railway hub operations, intermediate work classes A5 or above are recommended. Ibikoresho biremereye nka marshalling yards bisaba ibikoresho byo ku rwego rwo hejuru bya A6-A8 kugira ngo bizewe mu bikorwa by'igihe kirekire, bikomeye.

Guhuza n'ibidukikije bigoye

Guhitamo ingufu z'amashanyarazi bigomba guhuza n'imiterere y'urubuga: Inzira z'amashanyarazi zikwiriye ibibanza bifite intera iri munsi ya metero 200, bitanga ibiciro bito ariko bisaba kubungabunga byinshi; Trench-mounted conductor rails serve areas require high ground leveling standards; Ingufu z'amashanyarazi za cable reel zishobora kwakira ingendo nyinshi, zishyigikira 380V cyangwa 10kV ingufu z'amashanyarazi. Umujyi wa Kigali utanga serivisi z'amashanyarazi zijyanye n'ibisabwa n'ibigo by'imari iciriritse.

Ku bintu byihariye nko kubaka umuyoboro wa gari ya moshi, inzitizi z'uburebure bwa crane hamwe n'ibisabwa byo kwirinda guturika bigomba kwitabwaho. Mu turere two hejuru cyane, moteri zikenera amavugurura yo hejuru kugira ngo zikore neza mu bihe by'umuvuduko wo hasi w'ikirere.

Guhitamo ubwoko bukwiriye bw'imiterere y'umubiri

Single-girder gantry cranes zifite imiterere ya truss zifite uburemere bworoheje hamwe no guhangana n'umuyaga muke, bigatuma zikwiriye ibikorwa byoroheje mu bigo bya gari ya moshi byo hanze. Inyubako za box-girder zitanga ubudahangarwa bwo hejuru hamwe nubushobozi bwo gutwara imitwaro ariko zifite uburemere buremereye hamwe no guhangana n'umuyaga muke gato, bigatuma zikwiriye inzira za gari ya moshi ziremereye. Henan Mine Crane's rail-mounted container gantry cranes use an optimized box-girder design, achieving a perfect balance between strength and stability. Iyo imbogamizi z'urubuga zibuza gushyirwaho kw'ibikoresho byuzuye, cranes za gantry za cantilever imwe zishobora gutorwa. Imiterere yabo ya asymmetrical ituma habaho imikoreshereze mike y'ikirere.

Ku bijyanye n'imikoreshereze y'ibicuruzwa byihariye, ibicuruzwa byihariye birashoboka. Uruhande rumwe rugendera ku mihanda mu gihe urundi ruhagarara ku butaka, bigatuma ziba nziza mu kuvugurura imihanda ya gari ya moshi isanzwe hamwe n'ihungabana rito ry'ibikorwa remezo.

Kugenzura iyubahirizwa ry'umutekano no gushyigikira serivisi

Ibikoresho bigomba kubahiriza ibipimo byinshi by'igihugu, harimo "General Gantry Crane Standard (GBT14405-93)" na "Code for Construction and Acceptance of Lifting Equipment Installation Projects (GB50287-2010)". Ibikoresho by'umutekano bigomba kuba bifite ibikoresho byuzuye: ibipimo by'imizigo, imipaka y'ingendo, na buffers ni ibintu by'ingenzi. Ibikoresho byo hanze bisaba inyongera y'umuvuduko w'umuyaga utangira mu gihe umuyaga urenze 10.8 m/s. Mu rwego rwa gari ya moshi, igihe cyo kugabanuka kw'ibikoresho kingana n'ihungabana ry'ubwikorezi, bigatuma ubushobozi bwo gutanga ibice by'uruganda n'ubufasha bwa tekiniki ari ingenzi cyane.

First, collect foundational project data: maximum lifting capacity, cargo dimensions, site span, operational frequency, etc. Icya kabiri, suzuma ibidukikije birimo ubushyuhe, ubuhehere, umuvuduko w'umuyaga, n'ingufu z'amashanyarazi. Then, preliminarily determine structural type and technical specifications based on these parameters. Icya kabiri, hamagarira abacuruzi gukora ubushakashatsi ku rubuga kugira ngo barusheho kunoza ibisobanuro by'ibisubizo.

Railway industry users can reference Henan Mine's successful case studies. Cranes zayo zateguwe ku mishinga myinshi ya gari ya moshi ya Belt and Road zakoze mu buryo bwizewe mu bice bigoye muri Afurika, Aziya y'Amajyepfo y'Uburasirazuba, n'ahandi. For railway freight yards mainly handling container loading/unloading, the Henan Mine rail-mounted container gantry crane is recommended. Designed for high-frequency, high-efficiency operations, this model significantly boosts freight turnover efficiency.

Guhitamo crane ya gari ya moshi ntabwo ari ugugura ibikoresho gusa ahubwo ni ishoramari mu kwizerwa kw'ibikorwa by'igihe kirekire. Hamwe n'ubuziranenge bw'ibicuruzwa byayo byo hejuru hamwe n'umuyoboro wa serivisi ku isi, Henan Mine Crane yabaye umufatanyabikorwa wizewe mu rwego rwa gari ya moshi, itanga ubufasha bwuzuye kuva ku nama yo guhitamo kugeza ku kubungabunga ubuzima bw'imishinga itandukanye ya gari ya moshi.
