Hauv kev tsim khoom, kev tsim kho, thiab kev xa khoom, cov cranes saum toj kawg nkaus yog qhov tseem ceeb rau kev ua haujlwm zoo thiab muaj kev nyab xeeb ntawm cov khoom hnyav. Cov neeg ua haujlwm kho tshuab no ua rau kev ua haujlwm yooj yim dua hauv ntau qhov chaw lag luam.
Cov Cranes Overhead Yog Dab Tsi?
Cov cranes saum taub hau (lossis choj) yog cov khoom siv tsa ntawm cov kev khiav siab, uas hla cov chaw xws li cov chaw tsim khoom thiab cov tsev rau khoom. Lub qauv choj taug kev raws cov kev khiav sib luag, nrog lub hoist thiab lub trolley rau kev txav khoom kab rov tav. Tsis zoo li cov cranes txawb, lawv tau teeb tsa rau hauv ib cheeb tsam tshwj xeeb, ua rau muaj kev thauj khoom hnyav sib xws thiab tswj tau.
Siv hluav taws xob, lawv muab kev tsa, txo qis, thiab kev tswj kev txav mus los kom meej - zoo tagnrho rau cov khoom me me lossis loj, txo kev puas tsuaj thiab txhim kho kev nyab xeeb.
Hom Cranes Overhead
Ib Leeg Girder Overhead Cranes
Nrog ib tug ncej txhawb nqa xwb, cov no tsis hnyav heev, tsim nyog tus nqi, tuav tau 1–20 tons. Zoo meej rau cov chaw me me mus rau nruab nrab uas muaj qhov chaw tsawg, siv tau thaj chaw saum toj kawg nkaus kom zoo tshaj plaws.
Ob Chav Girder Overhead Cranes
Muaj ob lub girder sib luag, lawv tuav tau 5–500+ tons, muab kev ruaj khov rau cov haujlwm hnyav hauv kev lag luam hlau, kev tsim nkoj, thiab kev lag luam tsheb. Kho tau nrog ntau hom hoist.
Cov ntawv thov ntawm Overhead Cranes
Kev tsim khoom
Tsiv cov khoom siv raw, cov khoom sib xyaw, thiab cov khoom tiav lawm raws cov kab ntau lawm. Hauv cov chaw tsim tsheb, lawv tsa cov khoom siv cav thiab cov thav duab; hauv cov chaw tsim hlau, tuav cov hlau kub kub, ua kom cov haujlwm ua haujlwm zoo dua.
Kev Khaws Khoom thiab Kev Thauj Mus Los
Muab cov pallets thiab cov thawv hnyav sib sau ua ke/rov qab los, kom qhov chaw cia khoom ntsug zoo dua. Ua kom cov khoom thauj/tso tawm sai dua hauv cov chaw khaws khoom, kom xa khoom raws sijhawm.
Kev tsim kho
Cov cranes gantry nqa cov hlau beams, cov vaj huam sib luag concrete, thiab cov tshuab, ua rau muaj kev tso chaw siab rau cov tsev, choj, thiab cov khoom siv.
Kev Ua Lag Luam Mining thiab Hnyav
Siv cov khoom siv thiab cov hlau hauv qhov chaw khawb av uas nyuaj, tiv taus plua plav thiab qhov kub thiab txias heev. Hauv cov chaw ua hlau, thauj cov hlau uas yaj lawm kom zoo.
Kev Tswj Xyuas Pov Tseg
Tsiv cov thoob khib nyiab, cais cov khoom siv, thiab thauj cov khoom siv rov ua dua tshiab, ua kom cov txheej txheem ua haujlwm yooj yim dua rau kev ruaj khov.
Cov Yam Tseem Ceeb Thaum Xaiv Lub Crane Overhead
Lub peev xwm nqa tau
Xaiv ib lub crane uas muaj peev xwm thauj khoom ntau tshaj qhov koj xav tau kom tsis txhob muaj kev puas tsuaj thiab muaj kev phom sij. Soj ntsuam cov khoom thauj uas ib txwm muaj thiab cov kev xav tau yav tom ntej kom haum rau lub sijhawm ntev.
Qhov Ntev thiab Kev Npog
Xyuas kom tseeb tias lub crane ntev sib npaug rau qhov loj ntawm lub chaw, ncav cuag txhua qhov chaw. Cov chaw loj tau txais txiaj ntsig los ntawm ob lub girder lossis cov gantry cranes ntev.
Kev Ceev thiab Kev Tswj
Cov haujlwm xav tau qhov ceev sib txawv: qhov tseeb qeeb rau cov khoom tawg yooj yim, kev txav mus sai dua rau cov kab ntim ntau. Cov cranes niaj hnub no muaj kev tswj qhov ceev sib txawv.
Cov yam ntxwv kev nyab xeeb
Muab qhov tseem ceeb rau kev tiv thaiv kev thauj khoom ntau dhau, kev nres thaum muaj xwm txheej ceev, cov qhov hloov txwv, thiab cov tshuab tiv thaiv kev sib tsoo. Ua ke nrog kev saib xyuas tsis tu ncua kom ua haujlwm tau zoo.
Cov xwm txheej ib puag ncig
Kev siv sab hauv tsev yuav xav tau cov cranes txheem; sab nraum zoov/chaw nyob hnyav yuav tsum tau cov txheej tiv thaiv thiab cov khoom tiv taus huab cua.
Cov Lus Qhia Txog Kev Txij Nkawm Rau Cov Cranes Overhead
Kev saib xyuas kom zoo yuav ua rau lub neej ntev, muaj kev nyab xeeb, thiab ntseeg tau, tiv thaiv kev puas tsuaj thiab kev kho nqi siab.
Kev Tshuaj Xyuas Txhua Hnub
Tshawb xyuas seb puas muaj kev puas tsuaj (tawg, qhov xoob) ntawm tus choj, lub tshuab nqa, thiab txoj kev khiav. Tshawb xyuas cov hlua hlau puas hnav, cov hooks puas muaj qhov tsis zoo, thiab tswj kev ua haujlwm. Tsum tsis txhob siv yog tias muaj teeb meem tshwm sim.
Kev Tshuaj Xyuas Tsis Tu Ncua Los Ntawm Cov Kws Tshaj Lij
Cov kev kuaj xyuas txhua peb lub hlis/ib nrab xyoo/txhua xyoo suav nrog kev puas tsuaj ntawm cov khoom siv kho tshuab, kev ua haujlwm ntawm lub tshuab hluav taws xob, thiab kev ua haujlwm ntawm cov khoom siv kev nyab xeeb. Cov kws tshaj lij pom cov teeb meem zais cia.
Kev ua kom lubrication
Ua raws li cov lus qhia ntawm lub chaw tsim khoom kom roj cov iav, log, thiab cov qhov tig, txo qhov kev sib txhuam. Ntxuav cov roj ntau dhau kom tsis txhob muaj cov khib nyiab sib sau ua ke.
Kev ntxuav
Ntxuav cov chaw tsis tu ncua kom tiv thaiv cov av qias neeg, pab nrhiav kev puas tsuaj thaum lub sijhawm tshuaj xyuas.
Kev Saib Xyuas Cov Hlua Hlau thiab Cov Saw
Xyuas kom cov hlua puas puas puas puas thiab puas xeb thiab xyuas kom cov saw hlau puas ncab; hloov raws li qhov xav tau. Xyuas kom ruaj ntseg txuas rau cov hooks.
Kev Saib Xyuas Hluav Taws Xob
Khaws cov khoom kom qhuav/huv kom tsis txhob muaj luv luv. Tshawb xyuas cov xov hlau thiab cov cav kom puas tsuaj lossis ua tej yam tsis zoo.
Kev Khaws Cov Ntaub Ntawv
Taug qab kev tshuaj xyuas, kev kho, thiab kev hloov khoom kom saib xyuas keeb kwm, txheeb xyuas cov qauv, thiab ua raws li cov qauv kev nyab xeeb.
