Iicranes ezingaphezulu zisetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo okuphatha kunye nezinto ezihambayo. Ezi cranes zifuna unikezelo lwamandla oluthembekileyo ukuze lusebenze ngokufanelekileyo nangokukhuselekileyo. Kukho iintlobo ezahlukeneyo zemigca yonikezelo lwamandla ekhoyo kwiikhreyini ezingaphezulu, nganye ineengenelo zayo ezizodwa. Kweli nqaku, siza kuxubusha iintlobo eziqhelekileyo zeendlela zokubonelela ngombane kwii-cranes eziphezulu.
1. IiNkqubo zikaLoliwe ze-Conductor: Olu hlobo lombane lufakwe ngaphezu komzila we-crane kwaye unikezela ngokuqhubekayo kunye nokungaphazanyiswa kwamandla ombane kwi-crane. Iinkqubo zikaloliwe ze-conductor kulula ukuzifaka kunye nokugcina kwaye zifanelekile kwizicelo ezinzima.
2. IiNkqubo zeFestoon: Olu hlobo lonikezelo lwamandla lubandakanya intambo okanye ikhonkco eliguquguqukayo elinqunyanyiswe phakathi komgaqo weenqwelomoya wecrane kunye nebhulorho okanye itroli. Iinkqubo zeFestoon zinoqoqosho kwaye zibonelela ngesisombululo sombane esiguquguqukayo nesiguquguqukayoiikhreyini eziphezulu.
3. Iinkqubo zeCable Reel: Olu hlobo lombane lusebenzisa i-spring-loaded cable reel efakwe kwibhulorho okanye kwitroli ukubonelela i-crane ngamandla njengoko ihamba ecaleni kwendlela. Iisistim ze-cable reel zomelele kakhulu kwaye zifuna ukugcinwa okuncinci, okuzenza zibe lukhetho oludumileyo kwizicelo ezinzima.
4. IiSystems ze-Insulated Conductor Bar: Olu hlobo lonikezelo lwamandla lubandakanya ibha ye-conductor e-insulated efakwe ngaphezu komgaqo we-crane, ukubonelela ngombane okhuselekileyo nothembekileyo kwi-crane. Iinkqubo zebar ye-conductor e-insulated kulula ukuyifaka kunye nokugcina kwaye inokusetyenziswa kumaqondo obushushu agqithisileyo kunye neendawo ezinzima.
Ngokubanzi, uhlobo lombane wonikezelo olusetyenziselwa iI-crane ephezulukuya kuxhomekeka kwisicelo esithile kunye nohlahlo lwabiwo-mali. Nangona kunjalo, kubalulekile ukukhetha umbane othembekileyo nokhuselekileyo ukuqinisekisa ukuba i-crane isebenza ngokufanelekileyo nangokukhuselekileyo. Ekugqibeleni, ukunikezelwa kwamandla afanelekileyo kunokuqinisekisa ukusebenza kakuhle kwe-crane, ukunceda ukwandisa imveliso kunye nokunciphisa ixesha lokuphumla.
