Ulwakhiwo olusisiseko
Iikhreyini ze-Underslung overhead, ezikwabizwa ngokuba zii-cranes ezisebenza ngaphantsi, ziyilelwe ukwandisa indawo kunye nokusebenza kakuhle kwizibonelelo ezine-headroom encinci. Amacandelo abo aphambili aquka:
1. Imiqadi yeRunway:
Le miqadi ifakwe ngokuthe ngqo kwisilingi okanye kwisakhiwo sophahla, ibonelela ngomkhondo wokuba i-crane ihambe ngobude bendawo yokusebenza.
2.Phelisa iiNqwelo:
Ifumaneka kwiziphelo zombini zegirder ephambili,ukuphelisa iinqweloamavili endlu ahamba ecaleni kwendlela engaphantsi yomgaqo weenqwelo-moya, evumela i-crane ukuba ihambe ngokuthe tye.
3.UmBhali oPhambili:
Umqadi othe tye ohamba umgama phakathi kwemiqadi yendlela yeenqwelo-moya. Ixhasa i-hoist kunye netroli kwaye ibalulekile ekuthwaleni umthwalo.
4.Hoist kunye neTrolley:
I-hoist, ebekwe kwitroli, ihamba ecaleni kwebhanti enkulu. Luxanduva lokuphakamisa kunye nokwehlisa imithwalo usebenzisa intambo yocingo okanye i-chain mechanism.
5.Isistim yokulawula:
Le nkqubo ibandakanya i-pendant okanye i-remote control kunye neentambo zombane, ezivumela abaqhubi ukuba balawule ukunyakaza kwe-crane kunye nokuphakamisa imisebenzi ngokukhuselekileyo.
Umgaqo wokuSebenza
Ukusebenza kweikhreyini ephantsi kwentlokoibandakanya amanyathelo alungelelanisiweyo amaninzi:
1.Ukuphakamisa:
I-hoist iphakamisa umthwalo ngokuthe nkqo usebenzisa intambo yocingo oluqhutywa yinjini okanye ityathanga, elilawulwa ngumsebenzisi.
2.Intshukumo ethe tye:
I-trolley, ephethe i-hoist, ihamba kunye ne-main girder, ibeka umthwalo ngokuthe ngqo kwindawo oyifunayo.
3.Ukuhamba:
I-crane yonke ihamba ecaleni kwemiqadi yomgaqo weenqwelo-moya, ivumela umthwalo ukuba uthuthwe kwindawo yokusebenza ngokufanelekileyo.
4.Ukwehlisa:
Xa sele ikwindawo, i-hoist ithoba umthwalo emhlabeni okanye kwindawo ekhethiweyo, igqibezela umsebenzi wokuphatha izinto.
Iicranes eziphantsi komhlaba zibonelela ngezisombululo zokuphatha izinto ezisebenzayo kwiindawo apho iinkqubo zemveli ezixhonywe emgangathweni zingenakwenzeka, zibonelela ngokuguquguquka kunye nokusetyenziswa ngokufanelekileyo kwendawo ethe nkqo.
