Kwiminyaka edlulileyo, ukusetyenziswa kweekhreyini ezinobunzima obukhulu kwihlabathi jikelele ibiyinto enqabileyo.Isizathu ibiyimisebenzi efuna iilifti ezingaphezu kwe-1,500 yeetoni ibimbalwa kwaye iphakathi.Ibali kuhlelo lukaFebruwari lwe-American Cranes & Transport Magazine (ACT) luphonononga ukwanda kokusetyenziswa kwaba matshini bakhulu namhlanje, kubandakanywa udliwano-ndlebe nabameli abakha iinkampani zabo.

Imizekelo yokuqala

Iikhreyini zokuqala ezinkulu zangena kwimarike phakathi kweminyaka yoo-1970 ukuya ekuqaleni koo-1990.Yayibandakanyiwe yiVersa-Lift yi-Deep South Crane & Rigging kunye neTransi-Lift yiLampson International.Namhlanje kukho amashumi amabini eemodeli zecrane ezikwaziyo ukuphakamisa phakathi kwe-1,500 kunye ne-7,500 yeetoni, uninzi lokuhlala kuluhlu lweetoni ezingama-2,500 ukuya kuma-5,000.

Liebherr

UJim Jatho, umphathi wemveliso weLiebherr wase-US osekwe kwi-lattice boom crawler crane uthi iikhrayini ezinkulu bezingundoqo kwindawo yepetrochemical nakwezinye iiprojekthi ezinkulu zebala lemidlalo.Eyona mega crane idumileyo kaLiebherr eUnited States yiLR 11000 enomthamo we-1,000 yeetoni.I-LR 11350 ene-1,350-toni ye-toni inobukho obuqinileyo behlabathi kunye neemodeli ezingaphezu kwe-50 ezisetyenziswa ngokusisigxina, ubukhulu becala kuMbindi Yurophu.I-LR 13000 enomthamo weetoni ezingama-3,000 isetyenziswa kwiindawo ezintandathu kwiiprojekthi zamandla enyukliya.

Lampson International

Isekwe eKennewick, eWashington, iLampson's Transi-Lift mega crane yaqalwa ngo-1978 kwaye iyaqhubeka nokwenza umdla namhlanje.Imifuziselo ye-LTL-2600 kunye ne-LTL-3000 ene-2,600 kunye ne-3,000-toni yokuphakamisa amandla afumene imfuno yokusetyenziswa kwiiprojekthi zeziseko zophuhliso kunye neplanti yombane, ibala lezemidlalo, kunye nokwakhiwa kwesakhiwo esitsha.Imodeli nganye yeTransi-Lift iqhayisa ngeenyawo ezincinci kunye nokuhamba okungaqhelekanga.

Tadano

Iicranes zeMega zazingeyonxalenye yepotfoliyo kaTadano de kwangowe-2020 xa ukufunyanwa kwabo iDemag kwagqitywa.Ngoku inkampani ivelisa iimodeli ezimbini kwindawo yabo yefektri eJamani.I-Tadano CC88.3200-1 (eyayiyi-Demag CC-8800-TWIN) ine-3,200-toni yokuphakamisa umthamo, kunye ne-Tadano CC88.1600.1 (eyayiyi-Demag CC-1600) inokuphakama kwe-1,600-toni.Zombini zisetyenziswa kwiindawo zehlabathi.Umsebenzi wakutshanje eLas Vegas wabiza i-CC88.3200-1 ukubeka i-ring 170-toni phezu kwenqaba yentsimbi kwi-MSG Sphere ezayo.Xa igqityiwe ngo-2023, ibala lemidlalo liya kuhlala ababukeli abangama-17,500.
