Kev tsim kho thiab Lifting Machinery
Nws yog siv rau cov tub ntxhais load-cov kabmob ntawm cov cranes, xws li booms, outriggers thiab lub ntsiab ncej. Nws lub zog siab tso cai rau sib dua, ntau dua kev tsim qauv yam tsis muaj lub peev xwm thauj khoom, txhawb nqa cov cuab yeej siv zog thiab ua haujlwm tau zoo. Nws kuj haum rau telescopic caj npab ntawm cov pob zeb twj tso kua mis tsheb thiab cov chaw ua haujlwm hauv huab cua, tiv thaiv kev ntxhov siab thiab hnyav hnyav kom ntseeg tau ntev - kev nyab xeeb.
Offshore thiab Marine Engineering
Nyob rau hauv qhov hnyav offshore ib puag ncig, nws tsim cov qauv tseem ceeb xws li jack-nce rig ob txhais ceg, offshore crane qhov chaw thiab platform thav duab. Nws zoo heev uas tsis tshua muaj - kub toughness hloov mus rau qhov txias txias, thaum tswj cov tshuaj muaj pes tsawg leeg ua kom zoo weldability rau cov rooj sib txoos loj. Nws kuj tseem txhawb nqa cov khoom siv hluav taws xob tawm sab nrauv, ua kom cov turbines ruaj khov nyob rau hauv cov khoom siv marine.
Mining thiab Hnyav - Cov Khoom Siv Ua Haujlwm
Hauv kev mining, nws ua rau hydraulic txhawb txhua kab, shearer lub cev thiab tsuas tsheb cov qauv. Nws tiv taus kev cuam tshuam hnyav, siab thiab puas, txuas ntxiv lub neej ntev thiab txo cov nqi kho. Nws kuj tseem muaj cov khoom siv hnyav hnyav thiab cov khoom thauj khoom, ua rau lawv ua haujlwm hnyav mining thiab lub ntiaj teb - txav cov haujlwm.
Infrastructure thiab Loj -Span Structures
Nws yog siv rau hauv kev ntxhov siab tseem ceeb-cov kabmob loj ntawm- txuas txuas, txo qhov hnyav tag nrho ntawm nws lub zog siab-rau- qhov hnyav piv rau kev tsim kho yooj yim dua thiab ruaj khov zoo dua. Nws kuj tseem txhawb nqa tshwj xeeb - cov kab thiab cov ncej ntawm cov terminals, warehouses thiab factories, kom muaj kev nyab xeeb rau cov khoom hnyav thiab qhov chaw loj.
