Ama-hoist kagesi angasetshenziswa njengempahla ezimele yodwa noma amafreyimu agxunyekiwe namathrekhi njengengxenye yesistimu yokuphakamisa.Lezi zinhlobo zamasistimu okuphakamisa yizi:
Injini Hoists
Ama-engine hoist, noma ama-cranes enjini, asetshenziselwa ukusiza izisebenzi ekufakeni nasekulungiseni izinjini zezimoto.Zenzelwe ukuphakamisa injini ngaphansi kwesivalo semoto.Ama-hoist azo kagesi abekwe phezu kohlaka oluqinile noluphathekayo lwesakhiwo.Uhlaka lwesakhiwo lunamasondo afakwe esisekelweni salo ukuze akwazi ukulawula i-hoist phezu kwemoto, kanye nokuyihambisa eduze kwesitolo semishini.Ukuphatheka kwayo kuyenza ifaneleke izinhlelo zokusebenza zangaphandle.Uhlaka lwesakhiwo lwamanye ama-hoists enjini luyagoqeka, ngakho lungonga isikhala uma lugcinwa.
Ama-Cranes aphezulu
Ukufakwa kwama-cranes angaphezulu kuhlelwa ngesikhathi sokuqala sokwakhiwa kwesakhiwo, njengoba kudinga inani elikhulu kakhulu lokusekelwa kwesakhiwo.Ama-cranes angaphezulu aphakamisa imithwalo esinda kakhulu ezindaweni eziphakeme kakhulu zokuphakamisa endaweni evalekile.
Kuma-cranes angaphezulu, kunamaloli amabili ahambisanayo abekwe emigwaqweni yezindiza .Imishayo yendlela yezindiza inesibopho sokusekela yonke i-crane engaphezulu kanye nomthwalo.Amaloli okugcina ahamba emigwaqweni yemigwaqo yezindiza kanye nebhuloho kanye nendawo yokuphakamisa ugesi.I-hoist kagesi ihamba ngobude bebhuloho.Ibhuloho lingaba ibhuloho elilodwa noma ibhuloho elihlanganisa kabili.I-single girder bridge crane ine-trolley eyodwa enqamula ugongolo olulodwa lwegirder, kanti ukhreni webhuloho obamba kabili unamatroli amabili anyakazisa i-hoist kagesi ngokuhambisanayo phakathi kwemishayo emibili yegirder.Ibhuloho kanye namaloli okugcina abekwe ngokuhambisana nomunye nomunye.Lolu hlelo luvumela i-hoist kagesi ukuthi ihambe kwesokunxele nakwesokudla (ngamaloli asekupheleni), futhi iye phambili nangemuva (ngebhuloho).Amapharamitha okuphakamisa nokubeka alawulwa ukude.
I-Monorail Cranes
Okhreyini be-Monorail bawuhlobo lwe-crane engaphezulu esetshenziswa ezindaweni zokukhiqiza kanye nezitolo zemishini ukuze kwenziwe imisebenzi yokuphakamisa nokubeka indawo.Zisetshenziselwa ukuhambisa imithwalo endaweni evinjelwe.I-trolley ye-hoist kagesi igijima ku-flange yangaphandle ye-I-beam eyodwa, eseyakhiwe kakade esakhiweni sosilingi sesakhiwo.
