I-Gantry Crane ye-Double Girder Beam Portal eyenzelwe wena

Ii-girders ezimbini eziphambili ze-double girder gantry crane zifakelwe kwii-outriggers ezimbini ukuze zenze i-gantry milo. Ayinalo iqonga lokuhamba elahlukileyo, inxalenye ephezulu ye-girder eyintloko isetyenziswa njengeqonga lokuhamba, kwaye ii-railings kunye neenqwelo zokuqhuba iitroli zifakwe kwikhava ephezulu ye-girder eyintloko. Iiplatifomu zokuhamba, ii-railings, kunye neeleli zee-double girder gantry crane ziyilwe ngokuhambelana nemigaqo yokhuseleko efanelekileyo kunye neenkcukacha zoyilo.

Olu hlobo lwekreyini lusebenza kumzila osezantsi kwaye lusetyenziswa kakhulu ekuphatheni nasekufakeni imisebenzi kwiindawo zokugcina impahla ezivulekileyo, kwizikhululo zamandla, kumazibuko nakwiindawo zokubeka imithwalo kaloliwe. Xa kuthelekiswa neekreyini zegantry ezinegirder enye, iikreyini zegantry zeportal ezinegirder ezimbini ezenziwe ngokwezifiso zifanelekile ngakumbi kwiiprojekthi ezinobuninzi obukhulu kunye nexesha elide lokwakha. Iphucula kakhulu amandla emveliso kunye nemveliso yemisebenzi yokulayisha nokukhupha impahla, kwaye sisixhobo esiphambili sokuphakamisa umgangatho kunye nokusebenza kakuhle kolwakhiwo lokupakisha.

Iikhreyini ze-gantry zifakelwa ngaphandle. Ngenxa yokuchatshazelwa rhoqo ngumoya, imvula kunye nelanga, isakhiwo esiphambili kunye nezinto zekhreyini ye-gantry ephindwe kabini ziya konakaliswa okanye ziguquguquke ngenxa yokugqwala, kwaye izinto zombane ezifanelekileyo kunye nezixhobo ziya kuguga. Oku akuchaphazeli kuphela ukusebenza kakuhle kwekhreyini ye-gantry, kodwa kunokubangela neengozi zokhuseleko emsebenzini. Ke ngoko, kuyimfuneko ukugcina ikhreyini ye-gantry rhoqo.

Ukusebenza kunye nobomi benkonzo yendlela nganye yokusebenza ye-gantry crane buxhomekeke kakhulu ekuthambiseni. Okokuqala, jonga intambo ye-hook kunye nentambo ye-crane ukuze ubone ukuba kukho iingcingo eziphukileyo, iintanda kunye nokugqwala okukhulu, uze uzicoce kwaye uzithambise. Okwesibini, jonga ibhloko ye-pulley, i-drum kunye ne-pulley inyanga nenyanga ukuze ubone ukuba kukho iintanda, kunye nokuba ii-bolts ze-pressing plate kunye nee-bolts zesiseko se-drum ziqinisiwe na. Xa i-drum shaft inxitywe malunga ne-5%, kufuneka itshintshwe. Xa ukuguguleka kodonga lwe-groove kufikelela kwi-8% kwaye ukuguguleka kwangaphakathi kufikelela kwi-25% yobubanzi bangaphakathi bentambo yentambo, kufuneka itshintshwe. Ukongeza, ii-bolts ze-reducer kufuneka zihlolwe rhoqo ukuqinisekisa ukuba ziqinisiwe.
