Cov khoom siv thauj khoom siv tau nquag siv tsis yog hauv thaj av ntawm peb lub ntiaj teb, tab sis kuj nyob rau hauv qhov chaw dej, vim tias kev tsim kho ntawm ntau yam hydraulic tsim yuav tsum tau tshwj xeeb cranes, tus tsim ntawm uas, nyob rau hauv lem, yog tag nrho yoog raws. ua haujlwm hauv dej. Floating cranes yog cov tshuab muaj peev xwm los daws cov haujlwm saum toj no. Yog li ntawd, peb yuav txiav txim siab cov chav no kom ntxaws ntxiv.

Destination

Floating cranes tau pib tsom mus rau kev tsim kho ntau yam txuas hniav, chaw nres nkoj, yees hauv cov dej hiav txwv, dej hiav txwv thiab dej hiav txwv. Lawv lub peev xwm nqa tau los ntawm 10 mus rau 100 tons. Cov qauv tsim tshwj xeeb ntawm cov tshuab no ua tau raws li qhov yuav tsum tau ua los ntawm Maritime Register, uas yog: pom lub zog, zoo meej buoyancy thiab stability.

Ntau yam

Tus qauv, ntab cranes yog:

• Kho. Cov chav no muaj cov masts ruaj, thiab yog li ntawd qhov kev txav ntawm cov khoom thauj hauv lub dav hlau kab rov tav tshwm sim vim qhov txav ntawm lub pontoon. Cov yam ntxwv no thaum kawg cuam tshuam rau kev ua haujlwm ntawm chav tsev - nws yog qhov tsawg heev. Muaj tseeb, thiab tus nqi ntawm cov kais dej no kuj qis.
• Gantry.
• Txhim kho nrog tilting boom. Nws yog cov tshuab nqa nqa no uas zoo tshaj plaws rau kev ua haujlwm nrog cov khoom loj. Vim qhov sib txawv ncav cuag ntawm lub boom, qhov kev ua tau zoo ntawm lub crane yog siab heev nyob rau hauv kev sib piv nrog mast counterparts. Tsis tas li ntawd, oscillating mast cranes muaj tus nqi qis qis, muaj peev xwm nqa loj thiab cov qauv yooj yim. Lawv boom yog nthuav tawm nyob rau hauv daim ntawv ntawm ib khub ntawm racks, uas converge ntawm ib tug mob lub kaum sab xis saum toj, thiab yog hinged rau lub pontoon nws tus kheej. Nyob rau hauv txoj hauj lwm thauj, lub boom yog tsau rau ib qho kev txhawb nqa tshwj xeeb uas tsim rau lub hom phiaj no. Kev txhawb nqa / txo qhov boom tshwm sim siv lub tog raj kheej hydraulic, iav khib, ntsia hlau ntaus ntawv, saw hoist system.
• Tawm tau. Qhov ua tau zoo tshaj plaws floating cranes. Lub boom ntawm ib chav tsev no muaj peev xwm tsis tsuas tilting, tab sis kuj rotating ib ncig ntawm nws ntsug axis. Nyob rau tib lub sijhawm, lub peev xwm nqa ntawm cov tshuab no tuaj yeem sib npaug rau ntau pua tons. Tsis tas li ntawd, cranes tuaj yeem muaj lub turntable lossis turntable.
• sib xyaws.

Kev cais raws lub hom phiaj

Txhua lub crane tuaj yeem siv rau kev thauj khoom thiab tshem tawm haujlwm hauv chaw nres nkoj, lossis rau kev teeb tsa ua haujlwm. Tau kawg, lub peev xwm thauj khoom ntawm chav tsev yuav ua lub luag haujlwm tseem ceeb. Raws li rau qib ntawm maneuverability, tag nrho cov cranes tuaj yeem yog tus kheej-propelled (piv txwv li, ASPTR-1 floating crane) lossis tsis-tus kheej-propelled. Yog tias nws tau npaj tseg tias lub crane yuav tau ua haujlwm ntau lub chaw nres nkoj ib zauglos yog txav mus rau qhov chaw zoo nkauj, ces qhov no nws yuav yog tus kheej-propelled (lawv siv pontoons nrog nkoj-hom contours).

Universal Machine

KPL ntab crane tau tsim tawm ntawm Kirov cog hauv St. Chav tsev muaj ob hom: nuv thiab tuav.

Lub tshuab yog tig tag nrho. Lub boom muaj ib tug lattice qauv thiab txuas nrog rau lub movable counterweight ntawm qhov ntsuas qhov system siv lub pob khawm sib dhos. Thaum lub sij hawm hloov qhov ncav cuag ntawm lub boom, lub jib tsiv nyob rau hauv lub opposite kev taw qhia nyob rau hauv relation mus rau nws, uas xyuas kom meej tias lub load yog nyob rau hauv qhov siab yuav tsum tau.

Tsim nta

Floating crane KPL-5 muaj AC motors ua haujlwm ntawm qhov hluav taws xob ntawm 220-380 V thiab muaj lub zog ntawm 267 kW. Qhov tam sim no yog tsim los ntawm lub tshuab hluav taws xob diesel teeb nyob rau ntawm ntug dej lossis hauv lub pontoon hull. Crane tswj hom - electromechanical.

Lub rotating ib feem ntawm lub crane nrog lub boom thiab tag nrho cov complex ntawm rotary thiab lwm yam lifting mechanisms yog nyob rau ntawm rollers, uas, nyob rau hauv lem, txav raws lub crown mounted ntawm lub beam tawb.

Crane nws tus kheej tsis yog nws tus kheej-propelled, thiab yog li nws tau txav mus los siv winches.

Txhawm rau nqa lub crane mus rau hauv txoj haujlwm thauj, txo qis lub boom thiab rhuav tshem lub tshuab hloov pauv mus txog. Yog li ntawd, qhov siab ntawm lub crane yuav raug txo kom 10 meters.

Crane yog tsim thiab siv rau kev thauj khoom thiabunloading cim, vim hais tias ntawm nws muaj kev kub ceev ntawm kev khiav hauj lwm. Lub crane tsis ua haujlwm rau kev teeb tsa vim nws lub peev xwm nqa tau tsawg, tab sis nws tuaj yeem siv los ua ib qho kev pabcuam crane nyob ze ntawm lub pob zeb ua vaj tse rau reloading cement los ntawm cov dej saum npoo av, tshem tawm cov ntoo thiab lwm yam khoom thauj. Yog hais tias cov khoom yuav tsum tau mounted yog lub teeb nyob rau hauv hnyav, ces ib tug crane kuj siv tau rau kev tsim kho.

Veteran

Lub ASPTR-1 tus kheej-propelled ntab crane tau tsim ntawm Krasnaya Kuznitsa shipyard nyob hauv nroog Arkhangelsk thaum Lub Rau Hli 30, 1962. Lub nkoj tau hloov pauv ntawm ib txhiab tons, lub peev xwm nqa tau ntawm 15 tons, qhov ntev ntawm 38 meters, dav ntawm 13 meters, thiab qhov siab ntawm 3.2 meters. Lub tshuab no tau raug xa mus rau qhov chaw nres nkoj ntawm Novorossiysk thiab koom nrog Lub Xeev Maritime Emergency and Rescue Coordination Service ntawm Lavxias Federation. Hmoov tsis zoo, Lub Kaum Hli 12, 2016, thaum lub sijhawm tso cov raj xa dej hauv qab dej, lub crane ua tsis tiav, vim tias nws yuav tsum tau rub mus rau ntawm ntug dej. Txawm li cas los xij, vim huab cua tsis zoo, lub tsheb poob. Muaj yim neeg nyob saum nkoj.
