Nrog rau txoj kev loj hlob sai ntawm kev lag luam of the elevator, tus nqi thiab qhov zoo ntawm kev lag luam of the elevator tau dhau los ua chaotic. Niaj hnub no, muaj ntau yam of elevators, boarding choj thiab thauj. Txawm li cas los xij, muaj ntau yam teeb meem khoom zoo hauv cov khoom tsim los ntawm qee cov tuam ntxhab. Txhawm rau kom tau txais txiaj ntsig loj, qee cov tuam txhab txiav cov fab hauv cov khoom siv raw ntawm cov khoom siv los txo cov nqi. Raws li cov chaw tsim khoom of elevator, nws yog ib qho tsim nyog yuav tau qhia koj paub qhov txawv ntawm lub elevator.
1. Hluav taws xob ua txhaum. Txawm hais tias cov khoom siv hluav taws xob ntawm lub elevator yog qhov yooj yim heev, qhov zoo ntawm cov khoom yuav tsum zoo. Cov khoom siv nrog cov khoom zoo tsis tshua muaj teeb meem, tab sis nws muaj qhov tsis zoo, uas yog, tus nqi siab. Yog li ntawd, ntau lub tuam txhab me siv cov khoom pheej yig kom tau txais txiaj ntsig ntau dua thiab ua rau muaj kev nyab xeeb ntxiv.
2. Lub peev xwm thauj khoom. Nyob rau theem pib ntawm kev tsim, kwv yees li 1.3 npaug ntawm lub peev xwm thauj khoom tiag tiag yuav raug tshwj tseg. Txawm li cas los xij, yog tias cov khoom siv tsis zoo siv nyob rau theem pib, qhov hardness thiab compressive peev xwm ntawm lub elevator yuav tsis ua raws li qhov yuav tsum tau ua. Yog tias tus nqi qis steel qauv siv, nws yooj yim rau deform thiab khoov.
3. Muaj qhov khoob ntawm kev siv cov neeg yuav khoom, thiab kev siv cov neeg ua haujlwm hauv kev tswj hwm yog chaotic. Leej twg siv tau. Scope ntawm daim ntawv thov yog invisibly nthuav. Tsis muaj cov neeg ua haujlwm tshwj xeeb los tswj lub elevator, thiab cov teeb meem yuav tshwm sim sai sai, yog li txo lub neej kev pabcuam.
