Floating cranes: ib txoj kev

Lifting khoom yog dav siv tsis tau tsuas yog nyob rau hauv lub teb chaws qhov chaw ntawm lub ntiaj chaw, tab sis kuj nyob rau hauv waterways, vim hais tias qhov kev siv ntawm ntau yam hydraulic lug tas yuav tsum tau ib tug tshwj xeeb crane, kev tsim kho ntawm uas, nyob rau hauv lem, yog kiag li txais mus ua hauj lwm nyob rau hauv cov dej sector. Floating cranes - tshuab uas muaj peev xwm daws tau qhov teeb meem hais los saum no. Yog li ntawd, peb xav txog cov units ntau.

lub sij hawm

Floating cranes, chiv teem rau qhov kev siv ntawm ntau yam txuas hniav, ports, yees nyob rau hauv qhov dej ntawm tus seas, dej ntws thiab dej hiav txwv. Lawv muaj peev xwm tej zaum yuav tsum yog los ntawm 10 mus rau 100 tons. Lub cim tsim los ntawm cov cav tov tag nrho raws li qhov tseem ceeb uas yuav tsum tau uas yog muab tso rau pem hauv ntej los ntawm tus Tubrog nkoj register, namely zoo durability, zoo meej buoyancy thiab stability.

hom

Structurally, floating cranes yog:

• Toggling. Cov units muaj ib tug tsau mast, thiab yog li ntawd lub zog ntawm tus luj nyob rau hauv ib tug kab rov tav dav hlau yog vim lub zog ntawm tus Pontoon. Qhov no feature muaj feem xyuam rau thaum kawg qhov kev kawm ntawm lub tsev - nws yog heev me me. Qhov tseeb thiab tus nqi ntawm cov cranes kuj tsis tshua muaj.
• Gantry.
• Nruab nrog ib tug tilting boom. Nws yog ib cov lifting machines lub feem ntau pom rau hnyav hnyav loads. Vim lub alternating emission kawm crane boom nws yog txaus siab nyob rau hauv kev sib piv nrog rau lub mast analogues. Tsis tas li ntawd, li qub nrog ib tug qev mast muaj ib tug uas tsis muaj nqi ntawm nws tus kheej, ib tug zoo kawg li load, thiab kuj yooj yim siv. Lawv xub tuaj raws li ib tug khub uas struts uas ntws los sib tshuam nyob rau apex ntawm ib tug mob kaum ntse ntse, thiab lub pivotally mounted Pontoon. Nyob rau hauv lub thauj txoj hauj lwm boom yog txuas mus rau cov kev pab, tshwj xeeb tshaj yog rau cov tsim. Lifting / tej tus boom yuav siv sij hawm qhov chaw siv jack, khib, ntsia hlau pab kiag li lawm, ib tug system ntawm Pulleys.
• Teb. Feem ntau cov high-kev ua tau zoo floating cranes. Xub ntawm tej chav tsev yog tsis tsuas muaj khoov, tab sis kuj tig hais txog nws cov ntsug axis. Nyob rau tib lub load peev xwm ntawm cov cav tov yuav ua tau sib npaug zos rau ob peb puas tons. Tsis tas li ntawd cranes tej zaum yuav qev kem los yog rotating platform.
• Chav.

Classification los ntawm lub hom phiaj

Tej floating crane yuav siv tog twg los rau nraum chaw thau khoom los yog unloading nyob rau hauv qhov chaw nres nkoj, los yog mus ua lub installation. Ntawm cov hoob kawm, yuav luag lub ntsiab lub luag hauj lwm yuav ua si taw qhia tsev muaj peev xwm. Nrog kev xav txog cov neeg kawm ntawv uas maneuverability, tag nrho cov li qub yuav ua tau ob qho tib si rau tus kheej-propelled (e.g., floating crane ASPTR-1) thiab mov. Thaum nws yog hais tias lub valve yuav tsum tam sim ntawd ua ntau ports los yog tsiv mus nyob rau impressive deb, nyob rau hauv uas cov ntaub ntawv nws yeej tuas ib tug self-propelled (siv Pontoons nrog nkhaus nkoj hom).

universal tshuab

Floating crane KPL ua ntawm cov nroj tsuag muaj npe tom qab Kirov nyob rau hauv St. Petersburg. Lub tsev muaj ob tug versions: ib tug nuv claw.

Lub tshuab yog ua steerable. Lub boom muaj ib tug lattice qauv thiab yog ua ke nrog ib tug movable counterweight balancing system siv lub pob khawm ua ke. Thaum lub caij ntawm kev hloov nrog rau kev hwm rau nws, uas saib kuas tias cov load ntawm cov yam siab ncaim jib boom yog tsiv nyob rau hauv kev coj rov qab.

tsim nta

Floating crane CPL-5 muaj AC motors khiav hauj lwm rau ib tug voltage ntawm 220-380 V thiab muaj ib tug muaj peev xwm ntawm 267 kW. Tus tam sim no ua ib tug diesel-generator txheej yog nyob rau ntawm lub puam los yog nyob rau hauv ib tug Pontoon lub cev. Crane hom tswj - electromechanical.

Lub rotating ib feem ntawm lub crane nrog ib tug boom thiab tag nrho complex raws thiab lwm yam lifting mechanisms nyob rau chais uas, nyob rau hauv lem, txav mus ze lub crown mounted rau cov girder tawb.

Los ntawm nws tus kheej, tus kais tsis yog nws tus kheej-propelled, thiab yog li ntawd nws yog txav tawm siv winches.

Yuav kom nqa cov crane nyob rau hauv lub thauj txoj hauj lwm, lub boom yuav tsum muab nws txo qis thiab rhuav lub mechanism ntawm kev hloov nyob rau hauv nws lawm. Raws li ib tug tshwm sim, lub qhov siab ntawm lub crane yog txo mus rau 10 meters.

Crane tsim thiab siv los mus ua hauj lwm tuav cov xwm, vim hais tias cov neeg uas nws muaj ib tug kev kub ceev ntawm lub lag luam. Installation ua hauj lwm crane tsis nqa tawm vim tsis muaj nqa lub peev xwm, tab sis nws muaj peev xwm yuav siv tau raws li ib tug pab ko taw los ntawm lub pob zeb ua tsob nroj rau MAAs unloading los ntawm cov dej, cov kua ntoo thiab lwm yam khoom. Yog hais tias mounted ntsiab yog sib, nws tso cai rau kev siv ntawm ib tug crane rau kev tsim kho.

qub tub rog

Lub self-propelled floating crane ASPTR-1 ua tau rau lub chaw nres nkoj "Liab ntaus", nyob rau hauv lub nroog ntawm Arkhangelsk, Lub rau hli ntuj 30, 1962. Lub nkoj qab thus muaj ib tug xaav ntawm ib txhiab tons thiab chaw thau khoom muaj peev xwm ntawm 15 tons, ib tug ntev ntawm 38 meters, ib tug dav ntawm 13 meters, ib qhov siab ntawm 3.2 meters. Qhov no tshuab tau raug ntaus nqi nyob rau hauv qhov chaw nres nkoj ntawm Novorossiysk, thiab tau koom rau hauv lub xeev Tubrog nkoj thaum muaj xwm ceev thiab cawm kom sib haum Service ntawm Lavxias teb sab Federation. Tu siab, lub kaum hli ntuj 12, 2016 thaum lub sij hawm pw ntawm underwater pipeline valve yog tawm ntawm kev txiav txim, ua rau nws yuav tsum tau muab cab rau tim ntug. Txawm li cas los, vim rau qhov huab cua tej yam kev mob ntawm lub tsheb poob. Nyob rau lub Rooj Tswjhwm Saib yim neeg.
