Lifting siv crane

Tus thawj crane nyob rau hauv thaum xyoo 1830 nyob rau hauv lub UK. Nws yog chav embodiment. Ib tug paub cov qauv uas muaj ib tug hydraulic, twb tsim 17 xyoo tom qab. Tab sis, yog hais tias ua ntej lawm, thaum thawj cranes, ua hauj lwm yog nqa tawm los ntawm thiab loj phau ntawv quab yuam los yog ib nrab mechanization, niaj hnub no, tej tsev, pib nrog me me los loj loj, muaj nyob rau hauv nws pov tseg rau cov kev siv crane.

Ib me ntsis ntawm lus qhia dav dav

Nws yuav tsum tau to taub hais tias ib tug ntaus ntawv xws li crane tsis muaj nyob. Muaj cranes. Qhov no lub sij hawm tau muab tsis tau Gosgortechnadzor. Kev Txiav Txim yog kwv yees li raws li nram no: crane - ib lub tshuab, muaj ib tug lifting lub cev (nuv, grippers, etc ...), uas yog siv rau kev txhawb nqa thiab tsiv hnyav loads.

Niaj hnub no, cov txheej txheem no yog dav siv nyob rau hauv kev tsim kho. Nyob rau hauv hauv paus ntsiab lus, los ntawm cov nyiaj txiag taw tes ntawm view, nws yog heev muaj txiaj ntsim. Niaj hnub nimno crane muaj peev xwm nqa ib tug load ntawm ntau tshaj 1000 tons, tab sis tus qauv 50-t peev xwm cranes yog haum rau kev tsim kho.

kev khiav hauj lwm mus los

Nws yuav tsum tau to taub hais tias kev txhawb nqa thiab kev tsiv cargo neeg teb xov tooj yuav tsum tau ua tej yam yooj yim manipulations (mus). Nyob rau hauv thawj theem yog nqa tawm cov qaug dab peg load. Yog hais tias nws yog ib tug qhob slab, nws yog tied, thiab siv tus nuv mus nqa nws. Yog hais tias qhov no yog qhov loj cov ntaub ntawv uas, cov ua hauj lwm nqa tawm muab. Qhov thib ob theem - stroke. Nws yog tus ncaj zog thiab unloading ntawm thauj khoom. Nyob rau hauv qhov tseeb, qhov no yog qhov tseem ceeb tshaj plaws nyob ntev, yog li cov ua hauj lwm yuav tsum tau ua zoo thiab tsis muaj jerks. Cov theem kawg - lub kaw ceev. Nws implies ib tug rov qab lifting ntaus ntawv mus rau lub starting txoj hauj lwm. Incidentally, tus mob stroke yog muab faib ua peb theem: acceleration, khov kho zog thiab braking. Cov thawj thiab thib peb theem yog cov tseem ceeb tshaj plaws, raws li nws tej zaum yuav tshwm sim nyob rau hauv ib co dynamic loads thiab, yog li ntawd, qhov uas yuav ntawm kev puas tsuaj mus rau lub rooj noj load.

Tsev crane thiab nws tsim

By thiab loj unit muaj ob peb tseem ceeb Cheebtsam. Cia saib lawv txhua txhua tus:

• Hlau siv - foundation siv crane. Tag nrho cov uas yuav tsum tau ntaus nqi no - nws spans, txhawb, sub, etc. Nws yuav tsum tau muab sau tseg hais tias lawv yog lattice-hom box thiab ... Lub tsev feem ntau siv lub thawv-hom hlau.
• lifting mechanism - muaj ib tug saj zawg zog lifting lub cev. Qhov no tej zaum yuav hlua los yog tej saw. Qhov no kuj yog ntaus nqi lifting pab kiag li lawm (lub voj grapple nuv thiab m. P.). Cov kev siv ntawm lifting khoom nuv cranes yog siv ntau feem ntau.
• Lifting lub cev - tsis siv neeg (sib ntsib los yog voj), nws yuav tsum tau heev me ntsis los ntawm txhais tes ua hauj lwm, raws li zoo raws li automatic (solenoid los yog pneumatic suction khob).

Raws li koj tau pom, cov kev siv crane - nws yog ib tug complex ntaus ntawv uas yuav tsum tau tas li saib xyuas thiab hloov cables, hooks thiab lwm qhov chaw thiab cov chav nyob.

Classification los ntawm cov qauv thiab muaj peev xwm txav

Tam sim ntawd nws yuav tsum tau muab sau tseg hais tias muaj yog tsis muaj ib qho kev faib uas qhia cov essence tiav. Qhov tseeb hais tias niaj hnub cranes yuav ua tau kom muab ob peb zog. Piv txwv li, lub nram qab no siv cranes nyob ua ib ke nyob rau hauv lub tsim:

• Jib - lifting lub cev nyob rau hauv cov ntaub ntawv no yog mounted rau cov boom. Nws yog ib cov cranes yog feem ntau siv nyob rau hauv kev tsim kho, raws li lawv ua yooj yim thiab muaj ua rau nws tau mus nqa tawm tag nrho cov ua hauj lwm sai sai txaus.
• Choj - Choj yog ib tug steel qauv, uas yog tshem tawm los ntawm lub lifting lub cev.
• Cable-hom cranes.

Raws li rau cov muaj peev xwm yuav tawm mus, nws yuav ua rau kev txiav txim zoo hais txog ob lub ntsiab hom: tsau thiab nws tus kheej-Elevating. Cov yav tas hom yog cia li siv rau kev tsim kho ntawm vaj tse. Nws peculiarity yog tias nws yog ntsia tau rau tus kwv tab tom ua. Raws li cov kev loj hlob ntawm lub tsev crane climbs los ntawm txoj kev tshwj xeeb mechanisms. Txawm tias nce siv mobile jib cranes, uas yog lom zem ntau vim kev yam ntxwv ntawm cov hlau lead hauv xyoo tsis ntev los. Xws li ib tug crane yog tom, yog tias tsim nyog, yooj yim tsiv mus rau lwm qhov chaw. Tam sim no wb mus ntxiv.

siv cov kev faib cranes

Crane ntauwd hom yog cov feem ntau muaj kuab nyob rau hauv pej xeem thiab cov muaj kev tsim kho. Qhov no yog vim lub fact tias lawv tso cai rau cov installation, dismantling thiab tsheb rog. Qhov no thiaj li ntau lawm cov nqi los ntawm speeding li ua hauj lwm. Tab sis tej zaum ib tug crane siv tsis mus vim hais tias ntawm ib tug tsis txaus tus naj npawb ntawm qhov chaw. Nyob rau hauv cov ntaub ntawv no, ib tug fast-erecting ntauwd crane. Nqa kev siv ntawm no hom ntawm zoo uas tsis xav tau ntau qhov chaw rau nruab nws. Txawm li cas los, xws li ib tug lifting ntaus ntawv yuav siv tsis tau nyob rau qhov siab ntawm cov vaj tse saum toj no 30 meters. Nws yog nthuav tias nyob rau hauv ib tug ua haujlwm valve yuav rhuav thiab tuaj txoos ua ke nyob rau lwm kev tsim kho qhov chaw uas muaj tsawg heev lawm cov nqi. Niaj hnub no nws yog ib tug ntawm cov feem ntau tau kev daws teeb meem tom qab tsheb cranes.

Roj Hmab-nkees thiab crawler crane

Xwb, ua hauj lwm rau pneumatic chassis yog zoo vim hais tias nws muaj ib tug high ntoo khaub lig. Nyob rau hauv hauv paus ntsiab lus, xws li ib tug kev tsim kho crane, yees duab koj yuav saib tau, yog siv nyob rau hauv ze rau tus kwv. Nws muaj kev tswj kom ua tau qhov no los ntawm txhim kho ntau yam tshuaj axes. Nyob rau hauv tas li ntawd, cov neeg teb xov tooj lub alarm yog heev zoo heev. Muaj yog ib tug computer, uas zoo eliminates tib neeg yuam kev, huab cua txias thiab thiaj li nyob. N. System.

Muaj kuj yog crawler crane. Nws yog ntsia tau rau hauv lub crawler. Txawm tias siab permeability, xws khoom muaj peev xwm ua hauj lwm zoo tsuas yog nyob rau pre-txheej txheem ntawm qhov chaw. Tsheb thauj mus los los ntawm txoj kev ntawm ib tug tshwj xeeb trailer uas tsub kom lub operating nqi. Uas yog vim li cas qhov no yog tsis ib txwm siv siv cov khoom. Cranes ntawm no hom yuav siv tau tsuas yog qhov chaw uas muaj lwm yam unsuitable.

xaus

Yog li ntawd peb hais txog nrog koj, hais tias yog qhov kev siv crane. Cov duab ob peb nrov qauv koj yuav nrhiav tau nyob rau hauv no tsab xov xwm. Nws yuav tsum tau muab sau tseg tias hnub no, qhov no lifting khoom yog siv qhov txhia chaw. Nws thiaj li pheej hmoo ntawm kev raug mob ntawm ntau lawm thiab txo tus nqi ntawm cov phau ntawv ua hauj lwm. Muaj ib tug loj tus naj npawb ntawm cov kais dej, qhov no siv rau ob qho tib si lawv hom thiab muaj peev xwm. Ib txhia yog tsim rau cov ceev ua hauj lwm thiab tsiv mus nyob rau lwm mobile kwv, lwm leej lwm tus, nyob rau hauv tsis tooj, tsa maj mam, tab sis heev hnyav loads, thiab sawv ntsug nyob rau hauv lub lis piam khoom, los yog txawm lub hlis.
