Ikhreyini engaphezulu(i-crane yebhulorho, i-EOT crane) yenziwe ngebhulorho, iindlela zokuhamba, iitroli, izixhobo zombane. Isakhelo sebhulorho samkela ubume bebhokisi obudityanisiweyo, indlela yokuhamba yekhreyini ithatha idrayivu eyahlukileyo enemoto kunye nesinciphisi sesantya. Ibonakaliswa ngesakhiwo esinengqiqo ngakumbi kunye nentsimbi yamandla aphezulu ngokubanzi.
♦NganyeI-crane ephezulukufuneka ibe nepleyiti ebonakala ngokucacileyo ebonisa ukunyuswa kwayo okulinganiselweyo.
♦ Ngexesha lokusebenza, akukho basebenzi bavunyelweyo kwisakhiwo se-crane yebhulorho, kwaye i-crane hook mayingasetyenziselwa ukuthutha abantu.
♦Ukusebenzisa iI-EOT crane ngaphandle kwelayisensi esemthethweni okanye phantsi kweempembelelo zotywala akuvumelekanga ngokungqongqo.
♦Xa usebenza nayiphi na i-crane ephezulu, umqhubi kufuneka ahlale egxininise ngokupheleleyo-akuvumelekanga ukuthetha, ukutshaya, okanye imisebenzi enganxulumananga nayo.
♦ Gcina i-crane yebhulorho icocekile; musa ukugcina izixhobo, izixhobo, izinto ezinokutsha, iziqhushumbisi, okanye izinto eziyingozi kuyo.
♦ Ungaze usebenze iEOT cranengaphaya komthamo olinganisiweyo womthwalo.
♦ Musa ukuphakamisa imithwalo kule meko ilandelayo: ukubopha okungakhuselekanga, ukugqithiswa komatshini, imiqondiso engacacanga, ukutsalwa kwediagonal, izinto ezingcwatyelwe okanye ezikhenkcezisiweyo emhlabeni, imithwalo enabantu phezu kwazo, izinto ezinokutsha okanye eziqhumayo ngaphandle kwamanyathelo okhuseleko, izikhongozeli zolwelo ezizaliswe ngokugqithisileyo, iintambo zocingo ezingafikeleliyo kwimigangatho yokhuseleko, okanye iindlela zokuphakamisa ezingalunganga.
♦ Xa iI-crane ephezuluuhamba ngendlela ecacileyo, umzantsi we hook okanye umthwalo kufuneka ube ubuncinane be-2 yeemitha ngaphezu komhlaba. Xa udlula kwimiqobo, kufuneka ibe ubuncinane ubuncinane be-0.5 yeemitha ngaphezu komqobo.
♦ Ngemithwalo engaphantsi kwe-50% yecrane yebhulorho'Umthamo olinganisiweyo, iindlela ezimbini zinokusebenza ngaxeshanye; kwimithwalo engaphezulu kwe-50%, inye kuphela isixhobo esinokusebenza ngexesha.
♦ Kwi-EOT cranengeekhonkco eziphambili kunye nezincedisayo, musa ukuphakamisa okanye ukuthoba zombini iigwegwe ngexesha elinye (ngaphandle kweemeko ezikhethekileyo).
♦ Musa ukuwelda, ihamile, okanye usebenze ngaphantsi komthwalo omisiweyo ngaphandle kokuba uxhaswa ngokukhuselekileyo.
♦ Ukuhlolwa okanye ukugcinwa kweekhreyini eziphezulu kufuneka kwenziwe kuphela emva kokusikwa kombane kunye nethegi yesilumkiso ibekwe kwiswitshi. Ukuba umsebenzi kufuneka wenziwe umbane, amanyathelo okhuseleko afanelekileyo kunye nokubekwa kweliso kuyafuneka.
♦ Ungaze ulahle izinto ezisuka kwibhulorho yekrene ukuya emhlabeni.
♦ Rhoqo jonga i-crane ye-EOT's umda iiswitshi kunye nezixhobo interlock ukuqinisekisa umsebenzi ofanelekileyo.
♦ Musa ukusebenzisa umda wokutshintsha njengendlela eqhelekileyo yokumisa kwiI-crane ephezulu.
♦ Ukuba i-hoist brake iphosakele, imisebenzi yokuphakamisa akufanele iqhutywe.
♦ Umthwalo omisiweyo weibhulorho cranemayingaze idlule phezu kwabantu okanye isixhobo.
♦ Xa u-welding kuyo nayiphi na inxalenye ye-crane ye-EOT, sebenzisa ucingo olunikezelweyo lomhlaba-Ungaze usebenzise umzimba wecrane njengomhlaba.
♦Xa ihuku ikwindawo esezantsi, ubuncinci imijikelo emibini yentambo yocingo kufuneka ihlale kwigubu.
♦Iikhreyini ezingaphezulumazingangqubani, yaye makungaze kusetyenziswe icrane ukutyhala enye.
♦Xa uphakamisa imithwalo enzima, isinyithi esinyibilikisiweyo, iziqhushumbisi, okanye iimpahla ezinobungozi, qala uphakamise umthwalo ngokukhawuleza ukuya kwi-100.-200mm ngaphezu komhlaba ukuvavanya isiqhoboshi's ukuthembeka.
♦ Izixhobo zokukhanyisa zokuhlola okanye ukulungiswa kwiikhreyini zeebhulorho kufuneka zisebenze kwi-voltage ye-36V okanye ngaphantsi.
♦Zonke izixhobo zombane zivuliweIikhreyini ze-EOTkufuneka isekelwe. Ukuba umzila wetroli awudityaniswanga kumqadi oyintloko, weld ucingo lokumisa. Ukumelana nokumisa phakathi kwayo nayiphi na indawo kwi-crane kunye nendawo yokungathathi hlangothi kwamandla kufuneka ibe ngaphantsi kwe-4Ω.
♦ Yenza uhlolo lokhuseleko rhoqo kwaye wenze ulondolozo lothintelo kuzo zonke izixhobo zecrane ezingaphezulu.
Izixhobo zoKhuseleko zeBridge Cranes
Ukuqinisekisa ukusebenza ngokukhuselekileyo kweekhreyini zebhulorho ye-hook kunye nokuthintela iingozi, kufakwe izixhobo ezininzi zokukhusela:
Layisha Limiter: Inqanda ukugcwala, unobangela omkhulu weengozi zecrane.
Ukutshintsha koMda: Ibandakanya imida yohambo oluphezulu nolusezantsi lweendlela zokuphakamisa, kunye nemida yokuhamba yetroli kunye nebhulorho.
Izithinteli: Funxa amandla e-kinetic ngexesha lentshukumo yetroli ukunciphisa impembelelo.
Izixhobo ezichasene nokungqubana: Thintela ukungqubana phakathi kweekhreyini ezininzi ezisebenza kwingoma enye.
Anti-Skew Devices: Ukunciphisa i-skewing ebangelwa ukuveliswa okanye ukufakela ukuphambuka, ukuthintela umonakalo wesakhiwo.
Ezinye izixhobo zoKhuseleko: Izigqubuthelo zemvula zezixhobo zombane, ii-anti-tipping hook zivuliweiikhreyini zeebhulorho ezinemigidi enye, kunye namanye amanyathelo okuqinisekisa ukhuseleko lokusebenza.
