Kuyini ukuqalisa i-gantry?

Ezweni lokwakha, ukusebenza kahle nokunemba kubalulekile. Isidingo sezixazululo ezintsha ezenza inqubo yokwakha ibe lula siholele ekuthuthukisweni kwemishini nemishini ethuthukisiwe. Enye yezinto ezisunguliwe ezisunguliwe kwakuyi-launch gantry crane, eyaziwa nangokuthi i-bridge launch crane. Lo mkhakha wobunjiniyela omangalisayo uguqula indlela amaphrojekthi okwakha amabhuloho aqhutshwa ngayo, uletha ukusebenza kahle nokuphepha okungenakuqhathaniswa. Kodwa iyini ngempela i-launch gantry, futhi iyizuzisa kanjani imboni yokwakha?

I-Launch gantry crane iyithuluzi elikhethekile elenzelwe ukwakha amabhuloho, ama-viaducts kanye nezinye izakhiwo eziphakeme. Isetshenziselwa ukuphakamisa nokubeka amabhuloho ekhonkrithi noma ensimbi akhiwe kusengaphambili ukuze kuhlanganiswe idekhi ngokushesha. Ama-gantry crane ngokuvamile aqukethe uhlaka oluqinile olusekelwa yiziqhumane ezidlula ubude bebhuloho. Ifakwe indlela yokuphakamisa enembile engaphakamisa amabhande ebhuloho asindayo ngokunembile nangokunembile.

Umsebenzi oyinhloko we-launch gantry crane ukwenza kube lula ukunyakaza okuvundlile nokuqondile kwama-bridge girders ngesikhathi senqubo yokwakha. Lokhu kufezwa ngokuhlanganiswa kwezinhlelo ze-hydraulic, mechanical kanye ne-electronic ezisebenzisana ukuqinisekisa ukusebenza okubushelelezi nokulawulwayo. Ikhono le-crane lokuqondisa izinto ezisindayo ngokunembile lenza libe ithuluzi elibalulekile kumaphrojekthi okwakha amabhlogo, okunciphisa kakhulu isikhathi kanye nomsebenzi odingekayo ukuqedela isakhiwo.

Enye yezinzuzo eziyinhloko zokusebenzisa i-crane ye-gantry eqalayo yikhono lokusheshisa isimiso sokwakha. Ngokubeka ngokushesha ibhuloho elilungisiwe endaweni yalo, ama-crane angahlanganisa ngokushesha idekhi, anciphise ukuphazamiseka kwethrafikhi futhi anciphise isikhathi sephrojekthi iyonke. Lokhu akugcini nje ngokuzuzisa inkampani yokwakha ekongeni isikhathi nezindleko, kodwa futhi kunomthelela omuhle emphakathini ozungezile ngokunciphisa ukuphazamiseka okuhlobene nokwakha.

Ukuphepha kungenye isici esibalulekile sokwakhiwa kwamabhuloho, futhi ukusetshenziswa kwama-crane okuphakamisa ama-gantry kuthuthukisa kakhulu ukuphepha ezindaweni zokwakha. Ngokunciphisa isidingo sokuphatha ngesandla ama-girders amabhuloho asindayo, ingozi yezingozi nokulimala ingancishiswa kakhulu. Izinhlelo zokulawula ezithuthukisiwe ze-crane kanye nezici zokuphepha ziqinisekisa ukuthi ukuphakamisa nokubeka imishayo kwenziwa ngokunemba okuphezulu nangokuhambisana nezinqubo zokuphepha.

Ukuguquguquka kwama-crane okuqalisa ama-gantry kuwenza abe yimpahla ebalulekile kumaphrojekthi okwakha amabhuloho. Amandla awo okwamukela imiklamo ehlukahlukene yamabhuloho kanye nokwakheka kwawo, kanye nekhono lokusingatha izinhlobo ezahlukene zama-brard girders, kwenza kube yisisombululo esiguquguqukayo nesiguquguqukayo sezidingo ezahlukahlukene zokwakha. Kungakhathaliseki ukuthi kuyindlela yokudlula emgwaqweni omkhulu, ibhuloho lesitimela noma indlela yokuhamba ngezinyawo, ama-crane okuqalisa ama-gantry angenziwa ngokwezifiso ngokwezidingo ezithile zephrojekthi.

Ngamafuphi, ukuqalisa ama-gantry cranes kumelela intuthuko enkulu kwezobuchwepheshe bokwakha amabhuloho, okunikeza ukusebenza kahle okungenakuqhathaniswa, ukuphepha kanye nokuguquguquka. Amandla ayo okusheshisa inqubo yokwakha, ukuthuthukisa amazinga okuphepha kanye nokuzivumelanisa nezidingo zephrojekthi ezahlukahlukene kuyenza ibe ithuluzi elibalulekile kumaphrojekthi okwakha esimanje. Njengoba imboni yokwakha iqhubeka nokukhula, ukwethulwa kwama-gantry cranes kukhombisa amandla okusungula izinto ezintsha okuqhuba intuthuko nokushintsha indlela esakha ngayo ingqalasizinda yesikhathi esizayo.
