Kreni ya m'madzi ndi mtundu wapadera wa kreni, yomwe ndi kreni yolemera yomwe imagwiritsidwa ntchito makamaka pa uinjiniya wa m'madzi, yomwe imagwiritsidwa ntchito makamaka pa ntchito zosiyanasiyana zolemera, ndipo ili ndi mawonekedwe a kugwira ntchito bwino kwambiri, kukhazikika komanso kudalirika.
Kapangidwe ka crane ya m'madzi nthawi zambiri kamakhala ndi chimango, dongosolo loyimitsa, dongosolo loyendetsa ndi dongosolo lowongolera. Chimangocho ndiye thupi lalikulu la crane, lomwe limalimbitsa crane ndikuchirikiza mbali zina za crane. Machitidwe oyika amagwiritsidwa ntchito kuyeza malo a crane ndikusandutsa chizindikiro chamagetsi kuti apereke mayankho olondola a malo. Dongosolo loyendetsa limapangidwa ndi mota, dongosolo la hydraulic ndi dongosolo lotumizira, momwe motayo imapangidwa makamaka ndi jenereta, injini, wowongolera ndi woyendetsa. Dongosolo lowongolera limagwiritsidwa ntchito kuwongolera kutumiza ndi kuyimitsa crane, komwe kumaphatikizapo masensa, owongolera, ogwiritsa ntchito ndi zina.
Ma crane a m'madzi ndi ma crane olemera ogwira ntchito bwino, okhazikika, komanso odalirika omwe amatha kugwiritsa ntchito magwero osiyanasiyana amagetsi ndikupereka ntchito zowunikira nyanja zomwe siziwononga chilengedwe.
Crane ya m'mphepete mwa nyanja ndi mtundu wa zipangizo zomwe zimagwiritsidwa ntchito kunyamula ndi kusuntha zinthu zolemera pamwamba ndi pansi pa sitimayo. Crane izi zimapangidwa kuti zipirire nyengo yovuta ya m'nyanja, kuphatikizapo mphepo yamphamvu, mafunde ndi dzimbiri la madzi amchere. Nthawi zambiri zimayikidwa pansi kapena padenga ndipo zimatha kuzungulira madigiri 360 kuti zithandize kunyamula ndi kutsitsa katundu.
Ma crane a m'mphepete mwa nyanja amapezeka m'makulidwe ndi mapangidwe osiyanasiyana, kutengera momwe amagwiritsidwira ntchito. Ena ndi ang'onoang'ono komanso onyamulika, opangidwira ntchito zopepuka, pomwe ena ndi akuluakulu komanso amphamvu, okhoza kunyamula zinthu zolemera zoposa matani 100. Amabweranso m'njira zosiyanasiyana, kuphatikizapo telescopic, knuckle suspenders ndi fixed suspenders.
Chifukwa chake ma crane a m'mphepete mwa nyanja ndi ofunikira
Pazifukwa zingapo, ma crane a m'mphepete mwa nyanja ndi zida zofunika kwambiri pa ntchito za m'mphepete mwa nyanja. Choyamba, ndi ofunikira kwambiri ponyamula ndi kutsitsa katundu m'sitima ndi m'sitima. Izi zikuphatikizapo chilichonse kuyambira makontena ndi ma pallet mpaka zida zolemera ndi magalimoto. Ngati palibe crane ya m'mphepete mwa nyanja, katunduyo ayenera kukwezedwa ndi kutulutsidwa pamanja, zomwe zimatenga nthawi yambiri komanso zovuta.
Ma crane a m'mphepete mwa nyanja nawonso ndi ofunikira kwambiri pa ntchito za m'mphepete mwa nyanja, kuphatikizapo kufufuza mafuta ndi gasi, kumanga ndi kukonza m'mphepete mwa nyanja. Ma crane amenewa angagwiritsidwe ntchito kunyamula ndikuyika zida za pansi pa nyanja, kukonza malo osungiramo zinthu m'mphepete mwa nyanja, komanso kunyamula katundu ndi zida kupita ndi kuchokera kumadera ozungulira nyanja.
Chifukwa china chofunikira cha ma crane a m'mphepete mwa nyanja ndi kuthekera kwawo kukonza chitetezo. Ndi ma crane a m'mphepete mwa nyanja, ogwiritsa ntchito amatha kunyamula ndikusuntha zinthu zolemera mosatekeseka popanda kuvulaza iwowo kapena ena. Izi zimachepetsa chiopsezo cha kuvulala, ngozi ndi kuwonongeka kwa katundu kapena zombo.
Mitundu yosiyanasiyana ya ma crane a m'nyanja
Monga tanenera kale, pali mitundu yosiyanasiyana ya ma crane a m'madzi, omwe ali ndi makhalidwe ndi ntchito zake zapadera. Mitundu yodziwika bwino ya ma crane a m'madzi ndi awa:
Crane ya Telescopic - Crane ili ndi mphamvu yobweza ya hydraulic yomwe imalola kuti ifike patali kwambiri. Nthawi zambiri imagwiritsidwa ntchito kunyamula ndi kutsitsa katundu.
Kreni ya Knuckle jib - Kreni iyi ili ndi mizere yolumikizana yomwe imatha kupindika ngati knuckle kuti inyamule zinthu pamwamba pa zopinga. Mu usodzi, nthawi zambiri imagwiritsidwa ntchito kukweza maukonde osodza ku sitimayo komanso pansi pa sitimayo.
Kreni yokhazikika ya boom - kreni ili ndi boom yokhazikika yomwe singasunthidwe; Komabe, imatha kuzungulira madigiri 360. Nthawi zambiri imagwiritsidwa ntchito mumakampani opanga mafuta ndi gasi kunyamula zida zolemera ndi zinthu zina kupita nazo kapena kuzichotsa m'mphepete mwa nyanja.
Mapeto
Kreni ya m'nyanja ndi chida chofunikira kwambiri pa ntchito za m'nyanja. Kuyambira kunyamula katundu ndi kutsitsa katundu mpaka ntchito za m'nyanja, makreni awa amagwira ntchito yofunika kwambiri pachitetezo ndi magwiridwe antchito a m'nyanja. Pali mitundu yosiyanasiyana ya makreni a m'nyanja, iliyonse ili ndi makhalidwe ake apadera komanso ntchito zake, kotero ndikofunikira kwambiri kusankha kreni yoyenera kugwiritsidwa ntchito. Ngati mukufuna kreni ya m'nyanja, chonde onetsetsani kuti mwagwirizana ndi ogulitsa odalirika, omwe angakuthandizeni kusankha kreni yoyenera zosowa zanu.
