Cov chaw ua haujlwm tsuas yog tawv heev, nrog kev sib txhuam ore tsis tu ncua, kev cuam tshuam rau cov neeg kho tshuab hnyav thiab cov khoom hnyav hnyav uas hnav cov khoom thauj sai sai. Ib txwm Q235 thiab Q345 cov hlau me me yog pheej yig tab sis tsis zoo rau kev ua haujlwm mining hnyav, ua rau trailer hnav, deformation thiab weld tawg, tsis tu ncua kev kho thiab nqi qis. Los ntawm qhov sib txawv, siab - lub zog steels zoo li NM450 thiab Hardox® muab kev ua tau zoo dua. Nrog HB450 hardness thiab 2.5 npaug ntau dua hnav tsis kam tshaj cov hlau zoo tib yam, ntxiv rau 1250MPa yield zog, lawv tso cai thinner, 15% -19% sib zog trailer lub cev. Qhov no boosts cargo muaj peev xwm, txhim kho txoj kev ruaj ntseg thiab ncua kev pab cuam lub neej zoo heev.
Txawm hais tias tus nqi siab dua, cov hlau no muaj cov txiaj ntsig ntev heev -. Nws txiav cov kev ua haujlwm txij nkawm thiab kev poob qis, txo qis kev siv roj thiab emissions, thiab ua kom yooj yim ntau lawm los ntawm kev tshem tawm cov khoom siv ntxiv. Nws kuj ua kom muaj kev nyab xeeb siab nrog kev nruj heev, qaug zog thiab kub tsis kam, tiv thaiv kev xau thiab rollover txaus ntshai. Cov khoom siv rov ua dua tshiab thiab eco-tus phooj ywg, nws kho cov tsoos trailer 'qhov tsis zoo, ua kom ruaj khov, tus nqi- ua haujlwm tau zoo thiab ruaj khov mining fleet.
