Kev faib tawm yooj yim ntawmkev sib npaug ntawm craneMuaj peev xwm muab faib ua peb pawg, thawj zaug yog lub tshuab sib npaug crane, uas yog hom crane sib npaug feem ntau, uas yog, siv lub cev muaj zog los tsav lub hau kom nce mus tsa cov khoom; qhov thib ob yog pneumatic balancing crane, uas feem ntau siv cov cua los nqus cov khoom, kom ua tiav kev tsa. Hom thib peb yog hydraulic counterbalance crane, uas feem ntau yog siv rau kev tsa cov khoom hnyav.
Lub txeelub crane sib npaugnrog nws "qhov sib npaug ntawm lub ntiajteb txawj nqus" ua rau kev txav mus los du, tsis muaj zog thiab yooj yim, thiab tshwj xeeb tshaj yog rau cov txheej txheem tom qab kev tuav thiab sib dhos ntau zaus, uas tuaj yeem txo qhov siv zog ua haujlwm thiab txhim kho kev ua haujlwm zoo.
Nws feem ntau yog siv rau hauv cov nroj tsuag kho tshuab, kev thauj mus los, petrochemical, thiab lwm yam kev lag luam sib zog, thiab muaj kev ua tau zoo heev hauv kev thauj khoom thiab tshem tawm cov cuab yeej siv tshuab, cov kab sib dhos, cov kab ua tiav, kev thauj khoom thiab tshem tawm cov khoom tiav, cov thawv xuab zeb, thiab cov khoom hauv tsev rau khoom.
Peb qhov zoo tshaj plaws ntawm kev sib npaug crane.
1. Kev ua haujlwm zoo intuitively. Lub caj npab ntawm lub crane counterbalance yog tsim raws li lub hauv paus ntsiab lus ntawm kev sib npaug nrog kev sib ntsib, thiab tib lub sijhawm, qhov hnyav ntawm cov khoom ntawm tus nuv (lifting hnyav) tsis rhuav tshem qhov sib npaug no. Tsuas yog me me dov kev sib txhuam tsis kam yuav tsum tau kov yeej thaum txav mus los.
2. Ua haujlwm du. Vim nws lub caj npab khov kho, cov khoom uas tsa yuav tsis co yooj yim li lub crane lossis lub tshuab hluav taws xob thaum lub sijhawm txav mus los.
3. Yooj yim rau kev khiav lag luam. Tus neeg siv tsuas yog yuav tsum tuav lub khoom ntawm tes thiab nias lub pob hluav taws xob lossis tig lub tes tuav kom lub khoom txav mus rau hauv qhov chaw peb-seem raws li kev taw qhia thiab qhov ceev uas tus neeg teb xov tooj xav tau (qauv hloov pauv ceev counterbalance crane). Lub gravity-free hom balance crane muaj peev xwm tswj qhov ceev ntawm cov khoom txav mus los raws li tus neeg teb xov tooj lub siab nyiam thiab kev xav ntawm tes.
