Ni iki gihishe inyuma y'icyiciro cy'abakozi ba Bridge Crane? How are working classes A1-A7 categorized?

The working class of a bridge crane shows the intensity of its operational workload, especially showing the time-based workload and load capacity of the crane. Cranes zo mu bwoko bwa hook zishyizwe mu byiciro bitatu n'ibyiciro birindwi: A1-A3 (umurimo woroheje); A4-A5 (medium duty); A6-A7 (heavy duty). The magnitude of a bridge crane's duty class is determined by two capabilities: the frequency of crane usage, called the utilization rate; and the magnitude of loads borne, called the load condition. Mugihe cyubuzima bwayo bwikora, ikiraro cya crane ihura numubare wihariye wimirimo yakazi. A duty cycle encompasses the whole operational process from preparing to lift a load until the next lifting operation begins. The total number of work cycles shows the crane's use rate and serves as a fundamental parameter for classification. Iki gipimo gikubiyemo umubare w'ibikorwa byose byakozwe mu gihe cy'ubuzima bw'akazi bwagenwe. Kugena ubuzima bukwiriye bwa serivisi bisaba kwita ku bukungu, tekiniki, n'ibidukikije, hamwe no kubara ingaruka zo gusaza kw'ibikoresho.

Overall Work Class of Bridge Cranes: Light Duty (A1-A3): Rare lifts rated loads, usually handles light loads. Ahanini ikoreshwa mu gushiraho no kubungabunga ibikoresho mu nganda z'amashanyarazi cyangwa ahandi hantu hakorerwa akazi, cyangwa mu bigo by'ubucuruzi n'ububiko bukora kenshi. Medium Duty (A4-A5): Rimwe na rimwe izamura imizigo yashyizweho, akenshi ifata imitwaro yo hagati. Ikoreshwa cyane mu bigo by'ubucuruzi n'amagaraji, nk'imashini rusange n'amaduka y'amateraniro. Heavy Duty (A6-A7): Often lifts rated loads, usually handles heavy loads. Ikoreshwa mu bubiko bukoreshwa cyane n'ububiko, nk'ibikeneye igihe kirekire, gufata kenshi ibintu biremereye cyangwa inganda z'ibyuma.

Ni ngombwa kumenya ko icyiciro cy'abakozi ba crane y'ikiraro n'ubushobozi bwacyo bwo kuzamura ari ibintu bibiri bitandukanye. Lifting capacity refers to the mass of material lifted in a single operation, while working class represents the crane's comprehensive performance features. A higher lifting capacity does not necessarily mean a higher duty cycle; Ku rundi ruhande ariko, kuba ufite ubushobozi buke bwo kuzamura ntibivuga ko habaho umuvuduko muto w'umurimo. Kuri cranes zubwoko bumwe hamwe nubushobozi bwo kuzamura, inzira zitandukanye zumurimo zitera ibintu bitandukanye byumutekano kubice. Kwibanda gusa ku bushobozi bwo kuzamura mu gihe wirengagiza uruzinduko rw'akazi - nko gukoresha kenshi crane ifite umuvuduko wo hasi ku mutwaro wuzuye - byihutisha kwambara no gusenyuka ku bice bigeragezweho, byongera igipimo cyo kunanirwa, kandi birashobora no guteza impanuka.

Byongeye kandi, birakwiye kumenyekana ko urwego rw'imikorere y'ikiraro n'icyuma gitandukanye n'urwego rw'imikorere y'uburyo bwo kuzamura. Kuri crane imwe, kubera imizigo idahuje hamwe n'imikorere idasanzwe mu buryo butandukanye bw'akazi, ibipimo by'imikorere y'umuntu ku giti cye akenshi bitandukanya n'urwego rusange rw'imikorere ya crane y'ikiraro. This discrepancy requires special attention during component retirement and replacement for different mechanisms.

Muri iki gihe, uruzinduko rw'ibinyabiziga rwahindutse igikoresho cy'ingenzi cy'ubucuruzi bw'amabuye y'agaciro. Mugihe utumiza cranes zo hejuru, ni ngombwa gusuzuma gusa niba toni yujuje ibisabwa ariko kandi nuburyo nyabwo bwo gukoresha ikiraro kugirango umenye kugura ibikoresho bikwiye.

Nk'isosiyete itanga crane ku isi, Henan Mine Crane itanga ibicuruzwa byuzuye kuva kuri toni 5 kugeza kuri toni 500. Dutanga ibishushanyo byihariye bishingiye ku bishushanyo by'urubuga rw'abakiriya, imiterere y'umutwaro, hamwe n'ibipimo by'ibidukikije. Serivisi zacu zuzuye zubuzima zitanga ibisubizo bimwe, harimo kugenzura ahantu, gutegura igishushanyo mbonera no gutunganya, hamwe no kubungabunga buri gihe.
