Overhead crane(bhiriji crane, EOT crane) inoumbwa nebhiriji, nzira dzekufamba, trolley, magetsi emagetsi. Iyo bhiriji furemu inotora bhokisi welded chimiro, iyo crane yekufamba nzira inotora yakaparadzana dhiraivha ine mota uye kumhanya inoderedza. Iyo inoratidzirwa neyakagadziriswa chimiro uye yakakwirira simba simbi yakazara.
♦ Mumwe nomumwepamusoro craneinofanira kuva nendiro inooneka zvakajeka inoratidza kuti yakayerwa kusimudza simba.
♦Panguva yekushanda, hapana vashandi vanotenderwa pabhiriji crane chimiro, uye hoko yecrane haifanirwe kushandiswa kutakura vanhu.
♦Kushanda anEOT crane pasina rezinesi rinoshanda kana pasi pesimba redoro zvinorambidzwa zvachose.
♦ Paunenge uchishanda chero kireneti yekumusoro, mushandisi anofanira kugara akanyatso kutarisisa-hapana kutaura, kusvuta, kana zviitiko zvisingaenderani zvinobvumirwa.
♦ Chengetedza crane yebhiriji yakachena; usachengete maturusi, midziyo, zvinhu zvinobvira moto, zvinoputika, kana zvinhu zvine ngozi pazviri.
♦ Usambofa washandisa iyoEOT cranekupfuura chiyero chayo chakayerwa mutoro.
♦ Usasimudza mitoro mumatambudziko anotevera: kusungirirwa kusina kuchengetedzwa, mechanical overload, zviratidzo zvisina kujeka, diagonal pulling, zvinhu zvakavigwa kana chando kusvika pasi, mitoro ine vanhu vari pairi, zvinhu zvinopisa kana zvinoputika pasina matanho ekuchengetedza, midziyo yemvura yakawandisa, tambo dzetambo dzisingasviki mitemo yekuchengetedza, kana kukanganisa kusimudza nzira.
♦ Kana iyopamusoro craneinofamba nenzira yakajeka, pasi pechirauro kana mutoro unofanirwa kunge uri 2 metres pamusoro pevhu. Kana uchipfuura pamusoro pezvipingamupinyi, inofanirwa kunge iine 0.5 metres yakakwirira kupfuura chipingamupinyi.
♦Pamitoro isingasviki 50% yebhiriji crane's yakayerwa kugona, nzira mbiri dzinogona kushanda panguva imwe chete; kune mitoro inodarika 50%, nzira imwe chete inogona kushanda panguva.
♦ Pamusoro peEOT cranenemahoko makuru uye anobatsira, usasimudza kana kuderedza zvikorekedzo zvose panguva imwe chete (kunze kwemamiriro ezvinhu anokosha).
♦Usapinza, sando, kana kushanda pasi pemutoro wakaturikwa kunze kwekunge wakatsigirwa zvakachengeteka.
♦Kuongorora kana kuchengetedza pamakrane epamusoro kunofanira kuitwa chete mushure mokunge simba ratemwa uye tag yenyevero yakaiswa pane switch. Kana basa richifanira kuitwa nemagetsi, matanho ekuchengetedza akakodzera uye kutarisirwa kunodiwa.
♦ Usambofa wakakanda zvinhu kubva pabhiriji crane kusvika pasi.
♦Gara uchitarisa EOT crane's muganhu switch uye interlock zvishandiso kuti ive nechokwadi chekushanda kwakakodzera.
♦ Usashandise shanduko yekumisa seyakajairika nzira yekumisa yepamusoro crane.
♦ Kana mabhureki ehoist akanganisa, kusimudza mabasa hakufanirwe kuitwa.
♦Mutoro wakamiswa we abhiriji cranehaifanire kupfuura vanhu kana midziyo.
♦ Paunenge uchiputira pane chero chikamu cheEOT crane, shandisa waya yakatsaurirwa pasi-usamboshandisa muviri wecrane sepasi.
♦ Kana hoko iri panzvimbo yayo yakaderera, tambo mbiri dzetambo dzinofanira kuramba dziri padhiramu.
♦Overhead craneshaifaniri kuroverana, uye kireni haifaniri kushandiswa kusunda imwe.
♦ Paunosimudza mitoro inorema, simbi yakanyungudutswa, zvinoputika, kana zvinhu zvine ngozi, tanga wasimudza mutoro zvishoma nezvishoma kusvika ku100.-200mm pamusoro pevhu kuyedza brake's kuvimbika.
♦ Midziyo yekuvhenekesa yekuongorora kana kugadzirisa pamagetsi ebhiriji inofanira kushanda pamhepo ye36V kana pasi.
♦Makasi emidziyo yese yemagetsiEOT cranesinofanira kumiswa. Kana njanji yetrolley isina kusungirirwa padanda guru, weld waya yekudzika. Kupokana kwepasi pakati pechero poindi pane crane uye simba rakarerekera poindi inofanira kunge iri pasi pe4Ω.
♦ Ita ongororo yekuchengetedzwa nguva dzose uye ita kuchengetedzwa kwekudzivirira pane zvese zviri pamusoro pe crane midziyo.
Chengetedzo Zvishandiso zveBridge Cranes
Kuve nechokwadi chekushanda kwakachengeteka kwehook bridge cranes uye kudzivirira tsaona, akawanda ekudzivirira anoiswa:
Load Limiter: Inodzivirira kuwandisa, chikonzero chikuru chetsaona dzecrane.
Limit Swichi: Inosanganisira yekumusoro neyepasi miganho yekufamba yekusimudza nzira, uye miganho yekufamba yetrolley nemabhiriji kufamba.
Buffers: Bvisa kinetic simba panguva yekufamba kwetrolley kuti uderedze maitiro.
Anti-Collision Devices: Dzivirira kudhumhana pakati pema cranes akawanda anoshanda panzira imwe chete.
Anti-Skew Devices: Deredza skewing inokonzerwa nekugadzira kana kuisa kukanganisa, kudzivirira kukanganisa kwemaitiro.
Zvimwe Zvishandiso Zvekuchengetedza: Mavhavha emvura emidziyo yemagetsi, anti-tipping hook onsingle-girder bridge cranes, uye mamwe matanho ekuona kuchengetedzwa kwekushanda.
