Indlela Khetha i Telfer?

Bakuwufunqula phakamisa yokwakha - intliziyo naluphi nehlankomo wawaphakamisa izixhobo kuluhlu, yena indawo ekhethekileyo. Okwangoku kwimarike Russian unokumelana iintlobo ngeentlobo ukhwelisa ehlabathini lonke (ikakhulu Bulgaria, Russia, China) kunye namandla ezishiyanayo (uninzi ifuna izixhobo ephakamisa ethwele ukuya kwi-3 no-5). Ukuze ngokufanelekileyo wenze ukhwelisa ukhetho, kubalulekile ukuba oko, iinjongo, udinga ilifti (kwaye bayazi malunga neenkcukacha zayo). Iimpawu eziphambili ongcono ukuthembela xa ukhetha phakamisa - oku umthamo kwelayo, waphakamisa ukuphakama. Ngoku dwelisa iimpawu zasesekondari nayo ibalulekile xa kuthengwa phakamisa - le imo yokusebenza, isantya uyaziphakamisa, ubukhulu yomgama le wokuphakamisa izinto xa ububanzi umqadi ukuphakama kwaye apho kuya kufakelwa.

Zonke iintlobo ukhwelisa kube kalukhuni yahlulwe ngamaqela amabini - manual kunye zombane. Manual (okanye mechanical) yenzelwe mode nokusebenza lula, leyo ishenxisa imfuneko ukusebenza nangokukhawulezileyo. Plus phakamisa ncwadana ukuba lilize unikezelo lwamandla yombane ukuba ukusebenza kwayo, kuba iqhutywa ngeendleko amandla lo msebenzi. ukhwelisa zombane, yena, yahlulwe intambo kunye chain. Ithandwa kakhulu kwi ukuphakamisa imveliso - into mobile ukhwelisa zombane intambo efakiweyo I-beam girder crane. bomthwalo ufikelela wokuphakamisa izinto neetoni ezingama-50. Kufuneka kuqatshelwe ukuba ukhwelisa ngesandla ahluka yi amaxabiso aphantsi lombane nolufikelelekayo. Ngoko ke ukuba ngaba unayo imveliso encinane, kunye nokuvela umthwalo kufuneka kumaxesha ngamaxesha, lo wokuphakamisa izinto manual, kuya kuba ukukhetha eyona ndlela.

Kwiimeko ezininzi, ukhetho luba wokuphakamisa izinto manual yaye kule kukho izizathu ezithathu (dimensions amancinci ubunzima, umthwalo enkulu (iitoni ezili-10), kungenzeka ukuba basebenze kungekho ombane). rhoqo ukuphakamisa manual esetyenziselwa ufakelo ukhwelisa nzima zombane. Modern ukhwelisa Bulgarian manual luphawulwa nangobungcibi bamashishini umgangatho ophezulu kunye nomgangatho wenkonzo.

Qwalasela intambo kunye chain ukhwelisa. Ekuqaleni, lo isiqalelo ukunyusa i intambo bayitwabulula iseyilana (leyo isilonda igubu), kwaye eyesibini, intsimbi nemixawuka chain ulinganiswe (leyo esijikeleziswa yi izixhobo). Ibhulorho kunye gantry crane ngokuqhelekileyo kusetyenziswa ukhwelisa ngentambo yocingo, kunye milenge cantilever ekhwele ukhwelisa chain (ukhwelisa chain uyasilumeka ubunzima yenza kube lula entabeni). Emva kokufunda lo ngokutsha, uya kukwazi ukugcina benolwazi kwezixhobo ngokuziphakamisa, kodwa kuthathwa inkqubo- isigqibo sokugqibela kunye kwinkampani nomphathi emcela.
