Xav txog peb lub -wheeled electric tsheb lub thav duab li nws nraub qaum- tsis muaj nws, tag nrho cov khoom xws li roj teeb, lub cev muaj zog, thiab lub log yuav tsis tuav ua ke. Nws tsis yog ib tug hlau ncej xwb; Nws yog dab tsi ua kom lub tsheb ruaj khov thaum koj thauj khoom thauj, khiav haujlwm, lossis muab cov neeg laus nqa. Qhov tseeb, nws qhov zoo cuam tshuam ncaj qha rau qhov hnyav npaum li cas lub tsheb tuaj yeem nqa tau, kev caij tsheb zoo npaum li cas, thiab nws yuav kav ntev npaum li cas.
Ntawm cov khoom pem hauv ntej, qis- carbon steel thiab siab - lub zog alloy steel tseem yog qhov mus - rau kev xaiv - lawv nyob ruaj khov thiab yuav tsis tawg lub txhab nyiaj. Tab sis tsis ntev los no, ntau lub tuam txhab tau siv aluminium alloys lossis fiber ntau- cov khoom siv ntxiv los ua cov thav duab sib dua, uas pab txuag hluav taws xob. Vuam yog ib qho tseem ceeb heev -CO2 gas shielded vuam yog ib qho vim nws ua rau cov welds muaj zog txaus los tuav xyoo ntawm kev siv yam tsis hnav tawm.
Thaum nws los txog rau kev lag luam tiam sis, txhua leej txhua tus tau tsom mus rau peb yam: sib zog tsim, yooj yim dua -- sib dhos cov qauv, thiab zoo dua los tiv thaiv-corrosion tech (xws li cathodic electrophoresis) uas ua rau cov thav duab los ntawm xeb rau 8+ xyoo. Ntxiv rau, cov cai tswj kev nyab xeeb tau nruj dua, yog li cov thav ntawv tau txais cov tweaks ntse dua kom muaj kev nyab xeeb dua.
