Lub Txawb Khoom Noj Txiaj Ntsig, tseem hu ua lub xov tooj txawb pob khoom, muaj nws lub hauv paus hauv kev lag luam logistics, tawm hauv cov lus teb rau kev loj hlob ntawm kev thauj khoom thiab thauj khoom. Ntawm no yog keeb kwm thiab kev txhim kho lub tswv yim ntawm yuav ua li cas lub xov tooj txawb chaw thaib tau los ua thiab hloov mus rau hauv nws daim foos tam sim no:
Lub hauv paus pib: thaum ntxov 20th caug xyoo - cov kev daws teeb meem zoo li qub
Ntsiab lus:
Qhov nce ntawm kev lag luam thiab kev tsim khoom nyob rau hauv thaum ntxov xyoo 1900s tsim qhov kev xav tau sai thauj khoom thiab tsis hloov chaw ntawm cov khoom.
Thaum ntxov docks tau tsau-qhov siab thauj khoom bays, thiab yog tias lub tsheb thauj khoom lossis wagon tsis sib phim dock qhov siab, phau ntawv ua haujlwm lossis ua haujlwm ntawm daim txiag ntoo tau siv.
Txwv:
Cov pob quav dev zoo li qub tsis tuaj yeem pab tau txhua hom tsheb.
Kev tuav haujlwm qeeb thiab tsis nyab xeeb.
Tsis muaj qhov sib luag hauv lub mev txheej txheem lossis tsheb khiav tawm.
Rov tshwm sim ntawm cov kev daws teeb meem portable: nruab nrab -20 thi caug
Cov tsav tsheb tseem ceeb:
Kev loj hlob ntawm cov tsheb thauj khoom thiab thauj khoom thauj tom qab WWII.
Ntau ntau cov neeg caij nkoj ntau dua thiab lub tsheb siab.
Nrhav:
Ntoo lossis cov hlau ramps tau siv los ua cov kev daws teeb meem ib ntus.
Wheeled platforms tso cai Ramp.
Qhia cov qauv kev txhawb nqa kom muaj kev ruaj khov.
Formalization & Mechanization: 1960S-1980s
Cov Kev Tsim Nyog:
Tuam txhab uas muag tau hlau cov hlau txawb ramps nrog:
Tsau loj rau Forklifts mus ncig xyuas kev nyab xeeb.
Kev tuav jacks lossis saw hlau hoists kom hloov qhov siab.
Cov yam ntxwv:
Log Tshuab rau kev mus ncig.
Sab kev tiv thaiv kom muaj kev nyab xeeb.
Rov tshwm sim ntawm cov theem pib hydraulic (phau ntawv twj tso kua mis-ua hauj lwm).
Cuam tshuam:
Ua kom tiav kev saws me me hauv cov chaw khaws khoom thiab cov chaw xa khoom.
Ramps los ua cov khoom txheem txheem txheem hauv logistics cov chaw.
Cov txheej txheem ua thev naus laus zis: 1990s-2000s
Txhim kho:
Cov tshuab nqa hydraulic ua tau ntau txhim khu kev qha thiab yooj yim rau kev ua haujlwm.
Cov ntaub ntawv muaj zog (piv txwv li, hlau high-tensile) nce muaj peev xwm.
Anti-swb chaw zoo li steel grating txhim kho kev nyab xeeb.
Phuam cov khoom siv ua kom cov taub hau thiab cov tsheb thauj khoom kom rov ua kom cov ramp yooj yim.
Raug:
Modular cov qauv qhia tau qhia kom txo tus nqi thauj khoom.
Cov tuam txhab tshwj xeeb hauv kev cai khiav haujlwm rau kev lag luam tshwj xeeb (piv txwv li, dej haus, tsheb).
Niaj hnub nimno Era: 2010s-tam sim no
Advanced nta:
Dual-lub tog raj kheej cov tshuab ua smoother thiab nrawm dua.
Adjustable qhov siab ntau kom phim rau ib qho dav ntau hom tsheb.
Hnyav-Duty log thiab yooj yim maneuverability.
Load muaj peev xwm tam sim no ntau ntawm 6-30 tons.
Cim npe nrov: 10t lub xov tooj txawb, Tuam Tshoj, tuam ntxhab, cov chaw muag khoom, Hoobkas, yuav, kev muag khoom, rau muag, ua nyob rau hauv Suav teb
