S690QL yakakwirira simba simbi ndiro

Nekuda kwezvimiro zvesimba rakawanda, kushandisa S690QL kunosimudzira akaonda akagadzirwa zvimiro zvine yakawedzera payload kugona uye kushanda nesimba.
Iyo tekinoroji ruzivo rweS690QL yakatsanangurwa pazasi.
S690QL - Giredhi Dhizaini
Dhizaini yegiredhi re S690QL ndiyo anotevera:
S = Structural Steel
690 = zvishoma goho simba (MPa)
Q = Kudzima & Kudziya
L = Yakaderera notch kuoma kwekuyedza tembiricha

S690QL - Chemical Muumbirwo
Iyo kemikari inoumbwa yeS690QL inopiwa mutafura pazasi.
