Lub hauv paus ntsiab lus ntawm Boom Extension ntawm Crane

Lub boom ntawm crane feem ntau suav nrog ob ntu: lub ntsiab boom thiab jib. Muaj ob lub ntsiab ntawm lub ntsiab boom, ib qho yog truss qauv boom ua los ntawm welded profiles thiab cov kav dej, thiab lwm yam yog lub thawv qauv boom nrog ntau seem. Nrog rau txoj kev loj hlob ntawm tsheb cranes, feem ntau ntawm lub ntsiab booms ntawm tsheb cranes yog lub thawv-hom qauv, thiab tsuas yog ob peb tug yog truss lug.

Cov ntaub ntawv boom telescopic ntawm crane yog raws li nram no:

1. Sequential telescopic mechanism – txhua seem ntawm lub caj npab telescopic yog telescopic ib tug los ntawm ib tug nyob rau hauv ib tug tej yam sequence.

2. Synchronous telescopic mechanism - txhua ntu ntawm lub caj npab telescopic yog telescopic ntawm tib qhov sib txheeb ceev.

3. Kev ywj pheej telescopic mechanism - lub tshuab uas txhua caj npab tuaj yeem nthuav dav thiab cog lus.

4. Kev sib xyaw ua ke ntawm telescopic mechanism - thaum lub caj npab telescopic tshaj peb ntu, ib qho ntawm ob txoj kev telescopic tau hais los saum toj no tuaj yeem siv rau lub tshuab telescopic tib lub sijhawm.

Qhov zoo ntawm pinless tag nrho hydraulic telescopic mechanism yog tias caj npab ntev yog yooj yim hloov, muaj ntau hom kev ua hauj lwm caj npab ntev, thiab kev ua tau zoo heev. Qhov tsis zoo yog tias nws yog tus kheej tseem ceeb thiab muaj kev cuam tshuam ntau dua rau kev ruaj ntseg ntawm tag nrho lub tshuab. Lub pinless tag nrho hydraulic telescopic mechanism muaj qhov sib txawv ua ke, uas tuaj yeem ua ntau lub tog raj kheej hydraulic ntxiv rau ib-theem hlua kab, ib lub tog raj kheej hydraulic lossis ntau lub tog raj kheej hydraulic ntxiv rau ob-theem hlua kab.

Lub feature ntawm multi-hydraulic cylinder ntxiv rau ib-theem hlua kab yog hais tias lub xeem telescopic caj npab yog telescopic los ntawm hlau hlua, thiab lwm yam telescopic caj npab yog ncaj qha telescopic nrog roj thooj voos kheej kheej los ntawm txoj kev ntawm multi-theem cylinders los yog ntau lub tog raj kheej ib theem lossis ntau. -stage cylinders thiab ib-theem lub tog raj kheej liners. Yog li ntawd, qhov kev hloov ntawm seem ntawm lub xeem telescopic boom yog loj, thiab kev hloov ntawm seem ntawm lwm yam boom seem yog me dua.
