How to Choose a Portal Crane for Port Terminals: From Operational Requirements to Maximizing Efficiency

Nk'igikoresho gitandukanye cyo kuzamura ibyambu, cranes zo mu muhanda zigira uruhare rudashobora gusimbuzwa mu bihe nko gutwara imizigo myinshi, kuzamura imizigo rusange, no kohereza kontineri, kubera radius yabo izunguruka ya 360 °, imikorere ya boom yoroshye, hamwe nubushobozi bukomeye. Ku bibuga by'icyambu, guhitamo crane nziza ya gantry ntabwo bishobora gusa kuzamura imikorere y'ibikorwa hejuru ya 30% ariko kandi bikagabanya ikiguzi cy'igihe kirekire cy'akazi. Ariko, ibyambu bitandukanye bifite itandukaniro rikomeye mu miterere y'imizigo, imiterere y'ibicuruzwa, n'uburemere bw'imikorere. How should we exactly meet these requirements?

Step 1: Identify Core Operational Scenarios and Match Machine Functionality

Port terminals have complex and diverse operational scenarios, so the selection of gantry cranes must first clear the primary business focus and then tailor functional configurations accordingly.

Terminals mainly handling bulk cargo: Focus on high capacity + continuous operation

Imizigo minini nk'amakara, amabuye y'agaciro n'ibinyampeke yihariye hejuru ya 40% by'ingendo z'icyambu. Gantry cranes at such terminals must possess high-frequency cyclic operation capabilities and the ability to handle heavy loads:

Guhitamo gufata ni ingenzi: Hitamo ubwoko bwa grab bushingiye ku bunini bw'imizigo - ibikoresho biciriritse nk'amakara n'ibinyampeke bikwiriye gufata imigozi ine ya 10-30m³ (urugero, igipimo cyo gufata kwambara kuri Henan Mining's MG-type gantry cranes, ikoresha imibiri y'ibyuma ya Mn13 yo hejuru, yongerera ubuzima bwa serivisi inshuro 2 ugereranije n'ibyuma bisanzwe); Ku bikoresho by'uburemere bwinshi nk'amabuye y'agaciro, imigozi ibiri ya hydraulique ifite igitutu cyo gufunga ≥20 MPa irakenewe kugira ngo habeho uburyo bwizewe bwo kubungabunga umutekano nta kumeneka.

Work class must not be too low: Continuous-operation bulk cargo terminals should select gantry cranes with an A7 or higher work class. Ibikoresho nk'ibi bikoresha icyiciro cya H-class insulation kuri moteri yo kuzamura kandi bifite ibikoresho by'indishyi z'imyambaro kuri feri, zishobora kwihanganira amasaha 16 y'akazi kuzuye buri munsi n'akazi k'umwaka karenga toni miliyoni 1.

Kurinda umukungugu bigomba kuba bihagije: Ahantu hakunze kuvugururwa nko gufata ifu ya coke n'amabuye y'agaciro, ibyumba bifunze (hamwe na sisitemu yo guhumeka umuvuduko mwiza kugirango wirinde umukungugu winjira) hamwe n'ibifuniko by'umukungugu byo gukuramo bigomba gutangwa. Sisitemu yamashanyarazi igomba kuba ifite igipimo cyo kurinda IP65, hamwe n'ibifuniko by'umukungugu byashyizwe ku bice by'ingenzi nka moteri na contactors kugira ngo hirindwe umukungugu utera circuits ngufi.

General cargo and heavy-lift terminals: Enhanced precision control + compatibility with multiple lifting devices

Ibyuma, ibikoresho binini, imizigo y'umuyaga, n'indi mizigo rusange ifite imiterere idasanzwe, hamwe n'imizigo iremereye ipima toni 50-200, ishyira ibisabwa cyane ku guhinduka no guhagarara neza kw'ibikoresho byo kuzamura crane:

Sisitemu yibikoresho byo kuzamura igomba kuba "isanzwe": hamwe n'umugozi usanzwe, igomba gushyigikira ibintu byihuse nk'ibikoresho byo kuzamura kontineri, ibyuma by'ibyuma, hamwe n'ibikombe bya elegitoroniki (igihe cyo guhindura≤iminota 10). Ku bikoresho by'ibyuma birebire (urugero, metero 60 z'umuyaga w'umuyaga), telescoping auxiliary booms (uburebure bwa metero 3-8) irashobora gukoreshwa hamwe n'imikorere ya 360 ° yo kuzunguruka kugirango ugere kuri "kuzamura kumwe, ibice byinshi" kuzamura hamwe, kugabanya umubare w'imikorere.

Micro-motion performance is core: The hoisting mechanism must have a low-speed gear of 0.5-1 m / min, combined with a variable frequency speed control system to achieve "millimeter-level" control. Kurugero, mugihe cyo kuzamura moteri yubwato ya toni 200, sisitemu ya hydraulique ihindura neza umuvuduko kugirango yemeze ikosa ryo guhuza ≤5 mm, kurinda kwangirika kw'ibikoresho.

Imbaraga z'imiterere zigomba kuba zidakenewe: Boom ikorwa hakoreshejwe ibyuma bikomeye bya Q690, hamwe na modulus y'igice 30% hejuru y'iya cranes zisanzwe. When lifting eccentric loads (swing angle ≤3°), the boom stress real-time monitoring system automatically issues warnings to prevent structural overload deformation.

Multi-functional comprehensive terminal: Emphasizing quick switching + intelligent adaptation

Nk'icyambu cyuzuye gitwara imizigo myinshi, imizigo rusange, na kontineri, crane ya gantry igomba kuba ifite ubushobozi bwo "guhindura uburyo bw'imikorere hamwe na buto imwe":

Umuvuduko w'umuvuduko wa boom ebyiri: Yakozwe hamwe n'imiterere ibiri y'umuvuduko wa boom swing - umuvuduko mwinshi (80 m / min) n'umuvuduko wo hasi (10 m / min) - umuvuduko wo hejuru wongerera imikorere mugihe cyo kwimura imizigo minini, mugihe umuvuduko wo hasi utanga umuvuduko mugihe cyo guhagarara neza. Hamwe n'imikorere yo kwibuka angle ya boom, crane irashobora kugaruka mu buryo bwikora (urugero, hejuru y'umuyoboro w'ubwato) hamwe no gukanda buto imwe, kugabanya igihe cyo gukosora.

Sisitemu yubwenge yo "kugabanya umuzigo": Ifite imikorere yo guhinduranya imiterere yubwenge - mugihe uhinduye "uburyo bwimizigo myinshi", porogaramu ya grip anti-vibration ihita ikora; Iyo uhinduye "uburyo bwa kontineri," igikoresho cyo kuzamura micro-adjustment (±100 mm) gitangira. Ntibikenewe ko habaho gutunganya ibicuruzwa byihuse, bigatuma abakozi bashya babasha kwihutisha ibikorwa byabo.

Kugenzura neza ikoreshwa ry'ingufu: Ikoresha tekinoroji yo guhangana n'uburemere kugirango ihindure umwanya wa counterweight ukurikije uburemere bw'imizigo (gukosora metero 0-1.5), kugabanya ikoreshwa ry'ingufu mugihe cyimitwaro yoroheje no kongera ubudahangarwa mugihe cyimitwaro iremereye, bigatuma kuzigama ingufu hejuru ya 20% muri rusange.

Intambwe ya 2: Kwirinda: Kwirinda gukabya cyangwa kudakora neza

Guhitamo ibipimo bya gantry cranes bigomba guhuzwa n'ibikenewe byihariye, kwirinda ibiciro bitari ngombwa byo gukurikirana ibisobanuro byuzuye, cyangwa imbogamizi z'imikorere kubera ibipimo bidahagije.

Lifting capacity and reach: Calculate based on the farthest operating point

The lifting capacity of gantry cranes lowers with increasing reach. When choosing a model, use the maximum load at the farthest operating point as the baseline. Urugero:

Niba icyuma gikeneye kuzamura kontineri ya toni 25 kuri radius ya metero 30, icyitegererezo gifite ubushobozi bwo kuzamura toni ≥25 kuri radius ya metero 30 kigomba gutorwa (urugero, crane ya gantry ya toni 40/5, aho radius ya metero 30 ihuje nubushobozi bwo kuzamura toni 30), hamwe n'ikigero cyumutekano wa 10% cyo guhangana n'imitwaro itunguranye.

Ku bikoresho biremereye bisaba kuzamura ibikoresho bya toni 100 bifite uburebure bwa metero 20, crane yihariye ya gantry ifite ubushobozi bwo kuzamura toni ≥100 ku burebure bwa metero 20 igomba gutorwa kugira ngo yirinde ibikoresho bidakora kubera ibipimo bidahagije.

Lifting height: Covering all scenarios for ships and yards

Uburebure bwo kuzamura bugomba guhuza icyarimwe ibisabwa byo gupakira ubwato / gupakira no gupakira ubwato:

Uburebure bwo kuzamura hejuru y'ubuso bw'umuhanda: Ugomba gutwikira ubujyakuzimu bw'ubwoko bw'ubwato (urugero, ku bwato bunini bufite ubujyakuzimu bwa metero 15, uburebure bwo kuzamura bugomba kuba ≥metero 20) kugira ngo imizigo igarurwe hasi no mu gihe cy'umuvuduko muke.

Kuzamura uburebure munsi y'ubuso bwa gariyamoshi: Ku bikorwa biri munsi y'ubuso bwa terminal (urugero, gupakira / gupakira kontineri), byibuze metero 5 biragirwa inama kugirango wirinde igikoresho cyo kuzamura kugongana nibikoresho byo hasi.

Umuvuduko wo kuzunguruka: Ugomba kugenzurwa hagati ya 0.8-1.2 r / min. Umuvuduko ukabije ushobora gutuma imizigo ihungabana, mu gihe umuvuduko uri hasi cyane ushobora guhungabanya umuvuduko w'imikorere.

Umuvuduko w'ingendo za Gantry: 5-10 m / min biragirwa inama yo kugenzura neza inzira no kwirinda kugongana nibikoresho byegereye.

Umuvuduko wo kuzamura: ≥60 m / min ku mizigo myinshi iyo yashyizweho (kugirango wongere urugendo rwo kugaruka), ≤10 m / min ku mizigo iremereye (kugira ngo habeho umutekano).

Step 3: Adapt to port environment to extend equipment lifespan

Ibidukikije by'icyambu birangwa n'ubushyuhe bwinshi, ubuhehere bwinshi, igihu cy'umunyu, n'umuyaga mwinshi biteza imbogamizi zikomeye zikomeye kuri gantry cranes. Guhitamo ibikoresho bigomba gushyira imbere ingamba z'ubwirinzi zigenewe.

Ibipimo by'ingenzi bya hinge na shafts bikozwe mu cyuma kitagira ingeso 316, kandi bolts zivurwa na Darco, zemeza ko nta ruswa ikomeye mu bidukikije by'umunyu mu gihe cy'imyaka itanu.

Sisitemu y'amashanyarazi: Ibigo by'amashanyarazi bifite ibikoresho bigenzurwa n'ubushyuhe (ubushyuhe: 5-40 °C, ubuhehere ≤60%). Moteri yuzuyemo amavuta y'ubuzima bwose (akwiriye ubushyuhe kuva -30 ° C kugeza kuri 80 ° C), yemeza imikorere ihamye ku byambu byo mu turere dushyushye no ku byambu byo mu majyaruguru akonje.

Intambwe ya 4: Kugabanya ibiciro by'ibicuruzwa byagabanutse

The lifecycle of a portal crane spans 15-20 years, and a comprehensive service system can significantly reduce operational costs:

Ubushobozi bwa serivisi: Hitamo ibicuruzwa bifite sitasiyo za serivisi mu birometero 500 uvuye ku cyambu kugira ngo haboneke igihe cyo gusubiza amasaha ≤4 ku makosa hamwe n'ububiko buhagije bw'ibice bisanzwe (nka feri na valve ya hydraulique), no gusimbuza byarangiye mu masaha 24.

Customized training: Suppliers must provide targeted training—for bulk cargo operations, focus on training in grab unloading angle control; For heavy-lift operations, emphasize low-speed maneuvering techniques—to ensure that 80% of operators pass practical assessments.

Sisitemu yo kubungabunga ubwenge: Guha crane urubuga rwo gucunga ubuzima rugenzura kure imiterere y'ibice by'ingenzi ukoresheje vibration na sensor z'ubushyuhe, gutanga imiburo hakiri kare y'amakosa ashobora kuba (urugero, ubwiyongere bw'ubushyuhe budasanzwe), no kugabanya igihe cyo kuruhuka kitateganijwe hejuru ya 50%.
