Tower Crane Ukuphakama Isexwayiso

Inzwa yokulinganisa i-laser iyindlela yokulinganisa ibanga okungaxhumene nayo, engakala ibanga lezisebenzi ezingakwazi ukufinyelela noma izindawo ezithile ezikhethekile, futhi ukulinganisa kulula futhi kuphephile. Izinzwa ezihlanganisa i-laser zithembeke kakhulu uma uthatha izilinganiso ze-crane.
Inzwa yokuhlukanisa i-laser ikala ngokunembile ibanga eliqondiwe ngokusebenzisa i-laser, enokunemba okuphezulu, kulula kakhulu ukuyisebenzisa, futhi kulula ukuyifaka. Ngakho-ke, iphutha le-span ye-crane girder, ukuchezuka kwe-crane girder kanye nomugqa we-diagonal wesondo, ukuphakama okuqondile kwe-crane ukuya phansi, ukungqubuzana kwe-crane nezinye izici zokulinganisa nokunikeza isexwayiso kusenesikhathi.
