Niaj hnub nimno elevators feem ntau muaj xws li lub tshuab traction (winch), qhia rails, counterweight, kev nyab xeeb khoom siv (xws li ceev ceev tswj, nres nres, thiab buffers), teeb liab tswj system, tsheb, thiab tsaws qhov rooj. Cov khoom no tau nruab rau hauv lub tsev hoistway thiab chav tshuab, feem. Lawv feem ntau siv kev sib txhuam tsav nrog steel hlau ropes. Cov hlua hlau hlau hla dhau ntawm lub traction sheave, nrog rau txhua qhov kawg txuas nrog lub tsheb thiab qhov hnyav, feem. Lub cev muaj zog tsav lub traction sheave los tsa thiab txo lub tsheb. Cov elevators yuav tsum muaj kev nyab xeeb thiab txhim khu kev qha, muaj kev thauj mus los zoo, kev sib tw kom raug, thiab caij tsheb zoo. Cov yam ntxwv tseem ceeb ntawm lub elevator feem ntau suav nrog kev ntsuas lub peev xwm, cov neeg caij tsheb muaj peev xwm, ntsuas nrawm, lub tsheb qhov ntev, thiab hom hoistway.
traction system muaj xws li lub cev muaj zog traction, traction sheave, reducer, nres, traction tshuab puag, thiab handwheel. Lub traction sheave yog mounted ntawm lub load-bearing beam. Lub elevator traction tshuab yog lub tshuab tsav tsheb rau kev ua haujlwm of the elevator. Los ntawm kev thauj khoom -cov kabmob nqaj thiab traction sheave, nws bears tag nrho cov load (dynamic thiab static load) ntawm tag nrho cov reciprocating lifting Cheebtsam. Lub load-beam beam feem ntau yog ua los ntawm I-beam steel.
Lub ncua kev them nyiaj system muaj xws li traction ropes, tag nrho cov yam ntxwv ntawm lub tsheb thiab counterweight, compensating ropes, nro pulleys, thiab lwm yam. Lub tsheb thiab counterweight yog lub ntsiab Cheebtsam rau lub elevator lub ntsug txav; lub tsheb yog lub thawv ntim cov neeg caij tsheb thiab cov khoom.
Cov txheej txheem kev taw qhia suav nrog cov kev taw qhia thiab cov khau taw qhia, coj lub tsheb thiab qhov hnyav hauv lawv txoj kev nqa ntsug thiab txo qis.
Lub tshuab hluav taws xob yog lub elevator tswj qhov system, suav nrog ntau yam contactors, relays, controllers, thiab cov lus qhia.
Cov cuab yeej siv kev nyab xeeb suav nrog cov tswj ceev ceev, kev nyab xeeb nres, buffers, thiab ntau yam khoom siv hauv qhov rooj.
