Ukuqonda nokukhetha i-crane ye-onderd Bridge efanelekile
Lo mhlahlandlela ophelele uhlola ubunzima be Ama-cranes ebhuloho ngaphezulu, ukuhlinzeka ngemininingwane ebalulekile yokwenza izinqumo ezinolwazi ekukhetheni, ekusebenzeni, kanye nokulungiswa. Sizomboza izinhlobo ezahlukene, imininingwane ebalulekile, ukucatshangelwa kokuphepha, kanye nezinto okufanele zicatshangelwe lapho kuhlanganisa a ngaphezulu kwe-crane yebhuloho endaweni yakho yokusebenza. Funda ukuthi ungawengeza kanjani izinqubo zakho zokuphatha impahla ngesosi sekhambi esifanele sezidingo zakho ezithile.
Izinhlobo ze-Cranes ebhuloho eliphakeme
I-girder eyodwa ebheke ebhulohweni
Ginda esisha Ama-cranes ebhuloho ngaphezulu zibonakaliswa ukwakheka kwazo okulula nezindleko eziphansi. Zilungele amakhono okushisa akhanyayo kanye nezinhlelo zokusebenza lapho i-headroom ilinganiselwe. Lawa ma-Cranes avame ukutholakala kuma-workshop amancane namafektri. Idizayini yabo ehlanganisiwe ibenza balungele izikhala ezimfishane ngokuqhathaniswa nama-cranes aphindwe kabili. Kodwa-ke, umthamo wabo wokulayisha ngokuvamile uphansi.
I-Double Gew Orhead Bridge Cranes
Ginda kabili Ama-cranes ebhuloho ngaphezulu Nikeza amakhono aphezulu wokuphakamisa futhi yakhelwe imithwalo esindayo. Banikeza ukuqina okukhulu futhi ngokuvamile basetshenziswa ezindaweni eziningi eziningi zezimboni lapho izidingo ezinkulu zokuphakamisa zigcwele. Ukwakhiwa okuqinile kwemigwaqo ephindwe kabili ye-girder kuvumela izicelo ezifunwa kakhulu. Ngenkathi kubiza kakhulu kune-barder eyodwa, ziyindlela ekhethwayo yokuphakamisa okusindayo.
Eminye imidwebo ekhethekile ye-Overhead Bridge
Ngaphandle kwemiklamo ye-single and double girder, kukhona okukhethekile Ama-cranes ebhuloho ngaphezulu Okufana: Ama-Jib Cranes (avame ukusetshenziselwa izidingo ezincanyana, ezenzelwe indawo), ama-cantilever cranes (anwebeka ngale kwesakhiwo sokusekelwa), kanye nama-cranes ase-semi-gantry (ahlanganisa izici zebhuloho kanye nama-gantry cranes). Ukukhetha kuncike kakhulu kwizidingo ezithile zohlelo lokusebenza.
Ukucaciswa Okubalulekile Nokucatshangelwa
Ukukhetha okufanele ngaphezulu kwe-crane yebhuloho kudinga ukucubungula ngokucophelela imininingwane ebalulekile ebalulekile:
| Ukucacisa | Ukufanisa | Isisindo |
| Ukuphakamisa umthamo | Isisindo esiphezulu i-crane ingaphakamisa. | Kubalulekile ukuthola ukufaneleka kwemisebenzi ethile. |
| Isithombe esithi | Ibanga phakathi kwamakholomu okusekela ama-crane. | Inquma indawo yokumboza ye-crane. |
| Phakamisa ukuphakama | Ibanga elimile i-crane ingaphakamisa umthwalo. | Kubalulekile ukuthola ukuphakama kokwakha kanye nezidingo zokufaka impahla. |
| Ukuphakama kwe-hook | Ibanga elimile ukusuka phansi kuya ku-hook lapho i-crane isendaweni yayo ephansi. | Ukuthonya imvilophu yokusebenza ye-crane. |
Ukuphepha nokugcinwa
Ukuphepha kubaluleke kakhulu lapho kusebenza Ama-cranes ebhuloho ngaphezulu. Ukuhlola okujwayelekile, ukuqeqeshwa kwabasebenzisi, kanye nokubambelela emithethweni yokuphepha kubalulekile. Isondlo esifanele, kufaka phakathi ukufukula okufuywayo kanye namasheke engxenye, inweba isikhathi sokuphila kwe-crane futhi inciphisa ubungozi bezingozi. Ngemihlahlandlela ephelele yokuphepha kanye nemikhuba emihle kakhulu, thintana namazinga nemigomo efanele yomthetho.
Ukuthola umphakeli we-crane elungile
Ukukhetha umphakeli odumile kubalulekile. Umhlinzeki onokwethenjelwa uzohlinzeka ngemihlahlandlela yochwepheshe, anikele ngemihubhe yohlobo lokuhambisana nezidingo ezihlukile, futhi anikeze ukusekelwa okuqhubekayo nokulungiswa. Lapho usesha a ngaphezulu kwe-crane yebhuloho, cabanga ngezinto ezinjengedumela, isipiliyoni, iwaranti, nenkonzo yokuthengisa ngemuva. Ukukhetha okubanzi kwama-cranes aphezulu kanye nemishini ehlobene, cabanga ngezinketho ezivela kubahlinzeki abadumile abanjengeLowa Hitruckmall. Banikeza uhla oluhlukahlukene lwezixazululo zokuhlangabezana nezidingo ezahlukahlukene zokuphatha impahla yezimboni. Khumbula ukubekela phambili ukuphepha futhi ukhethe i-crane efanelekile kwisicelo sakho esithile.
Lo mhlahlandlela usebenza njengendawo yokuqala yokuqonda Ama-cranes ebhuloho ngaphezulu. Ukucwaninga okwengeziwe kumamodeli athile we-crane kanye nokubonisana nochwepheshe bezimboni kunconywa ngaphambi kokwenza isinqumo sokuthenga sokugcina.
