Winches muaj cov yam ntxwv hauv qab no: kev ua haujlwm siab, kev cog lus me me, ntim me me, lub teeb yuag, hnyav nqa lub peev xwm, thiab siv tau yooj yim thiab hloov pauv. Lawv tau siv dav hauv cov khoom nqa lossis nqa hauv tsev, kev txuag dej engineering, hav zoov, mines, docks, thiab lwm yam. Lawv kuj tuaj yeem siv los ua cov cuab yeej sib txuam rau niaj hnub tswj hluav taws xob tsis siv neeg ua haujlwm. Muaj 0 5-350 tons, muab faib ua ob hom: ceev thiab qeeb. Ntawm lawv, cov hnyav tshaj 20 tons yog loj tonnage winches. Winches tuaj yeem siv ib leeg lossis ua cov khoom ntawm cov tshuab xws li nqa, kev tsim kho, thiab mine hoisting. Lawv tau siv dav vim lawv txoj haujlwm yooj yim, txoj hlua loj winding muaj peev xwm, thiab kev txav chaw yooj yim. Cov kev qhia tseem ceeb ntawm lub winch muaj xws li ntsuas load, txhawb nqa, hlua ceev, hlua muaj peev xwm, thiab lwm yam.
Lub hom phiaj tseem ceeb ntawm lub winch yog siv los ua cov cuab yeej nqa khoom, siv rau kev nqa, dab dej, thiab tshem tawm (lifting) cov khoom siv hauv av thiab cov chaw hauv mines, uas yog, nqa ore, khib nyiab (gangue), nqa cov neeg ua haujlwm, txo cov khoom, cov cuab yeej. , thiab cov khoom siv raws lub qhov dej; Thib ob, raws li cov khoom siv thauj mus los, nws yog siv rau kev teem caij hauv av thiab kev thauj mus los ntawm cov ore (ore tsheb thauj khoom), mining site raking (slag) lossis filling, tshem cov ncej, thiab lwm yam.
