Isakhiwo Esiyisisekelo
Okhreni abangaphansi kwe-underslung overhead, abaziwa nangokuthi okhreni abagijima kancane, baklanyelwe ukukhulisa isikhala nokusebenza kahle ezindaweni ezinamakhanda alinganiselwe. Izingxenye zabo eziyinhloko zihlanganisa:
1. Imishayo yeRunway:
Le mishayo igxunyekwe ngqo kusilingi noma isakhiwo sophahla, ihlinzeka ngethrekhi yokuthi u-crane uhambe ngobude bendawo yokusebenza.
2. Qeda amakalishi:
Itholakala kuzo zombili iziphetho zebhande eliyinhloko,qeda amakalishiamasondo endlu agijima ngaphansi kwemishayo yendlela yezindiza, avumela i-crane ukuthi ihambe ivundlile.
3.I-Main Girder:
I-beam evundlile ehlanganisa ibanga phakathi kwemishayo yendlela yezindiza. Isekela i-hoist kanye netroli futhi ibalulekile ekuthwaleni umthwalo.
4.I-Hoist ne-Trolley:
I-hoist, efakwe kwi-trolley, ihamba eduze kwebhande elikhulu. Inesibopho sokuphakamisa nokwehlisa imithwalo kusetshenziswa intambo yocingo noma iketango.
5.Isistimu Yokulawula:
Lolu hlelo luhlanganisa i-pendant noma isilawuli kude kanye nezintambo zikagesi, okuvumela opharetha ukuthi balawule ukunyakaza kwe-crane kanye nemisebenzi yokuphakamisa ngokuphepha.
Isimiso Sokusebenza
Ukusebenza kwe-i-crane engaphansikuhilela izinyathelo ezimbalwa ezihlanganisiwe:
1.Ukuphakamisa:
I-hoist iphakamisa umthwalo uqonde phezulu kusetshenziswa intambo yocingo olushayelwa yinjini noma iketango, elilawulwa opharetha.
2.Ukunyakaza Okuvundlile:
I-trolley, ethwala i-hoist, ihamba eduze kwebhande elikhulu, ibeka umthwalo ngqo endaweni oyifunayo.
3.Ukuhamba:
Wonke ama-crane ahamba eduze kwemishayo yezindiza, okwenza umthwalo uthuthwe endaweni yokusebenza kahle.
4.Ukwehlisa:
Uma ususendaweni, i-hoist yehlisa umthwalo phansi noma endaweni ekhethiwe, iqedela umsebenzi wokubamba impahla.
Okhrayini abangaphansi abaphezulu banikeza izixazululo ezisebenzayo zokubamba izinto endaweni lapho amasistimu aqhele ukukhwezwa phansi engenzeki, enikeza ukuguquguquka nokusebenzisa kahle isikhala esime mpo.
