Qhov no yog lub tshuab ua haujlwm nyuaj uas tsim los rau qhov hnyav - lub luag haujlwm ntawm kev nqa thiab txav cov thawv thauj khoom hnyav. Nws cov khoom yog tsim rau lub zog loj, precision, thiab kev ntseeg tau.

Cov Cheebtsam tuaj yeem muab faib ua tsib lub hauv paus loj:

1. Cov Qauv Txheej Txheem

Qhov no yog lub crane lub cev pob txha, tsim los tiv taus cov khoom hnyav thiab ib puag ncig.

Lub Npe Lub Npe (2):Thawj kab kab kab rov tav uas tsim tus choj. Lawv yog fabricated li weldedbox girdersrau siab tshaj plaws lub zog thiab rigidity, uas yog ib qho tseem ceeb los tiv thaiv deflection thaum nqa lub thawv ntim ntawm qhov kawg ntawm qhov kev ncua.

Ob txhais ceg (2 lossis 4):Cov qauv kev txhawb nqa ntsug. Ib qho kev teeb tsa raug muaj ob txhais ceg, tab sis cov cranes loj heev yuav muaj plaub (ib qho ntawm txhua lub ces kaum). Lawv muab cov kev tshem tawm uas xav tau los ntim cov thawv siab thiab cov tsheb thauj khoom, tsheb ciav hlau, lossis lwm yam khoom siv.

Diagonal & Kab rov tav Braces:Steel bracing nruab nrab ntawm ob txhais ceg thiab girders. Cov no yog qhov tseem ceeb rau kev nqus cov quab yuam sab nraud, xws li cua thauj khoom thiab sab - rub lub zog thaum tsiv lub thawv, ua kom muaj kev ruaj ntseg tag nrho.

2. Hoisting thiab Trolley System

Lub kaw lus lub luag haujlwm rau qhov tseeb nqa, txo qis, thiab hla- mus ncig ntawm lub thawv.

Hoist Trolley:Ib qho hnyav - lub luag haujlwm thav duab uas khiav ntawm txoj hlua khi rau ntawmsaumntawm lub ntsiab girders. Qhov "sab saum toj-khiav" tsim no muab qhov siab tshaj plaws nqa qhov siab.

Main Hoist Unit:Mounted ntawm lub trolley, qhov no yog lub zog winch system muaj xws li:

Hoist Motor(s):Siab -torque, hluav taws xob motors.

Hoist Reducer (Gearbox):Multi-theem, precision gearbox uas hloov lub cev muaj zog ceev kom muaj zog, qis-ceev torque rau nqa.

Drum(s):Loj steel cylinders nyob ib ncig ntawm uas cov hlau ropes yog spooled.

Hlau Ropes:Siab -lub zog, tsis yog -rotating steel ropes. Feem ntau muaj 4 lossis 8 txoj hlua rau kev tuav lub thawv.

Nres:Thawj thiab theem nrab tsis ua haujlwm- nres nres (feem ntau yog hom disc) uas tau txais kev tuav lub nra.

Spreader:Qhov tshwj xeeb hauv qab no -- cov khoom siv sib txuas rau kev tuav cov thawv. Qhov no yog qhov "ntseeg" ntawm qhov system.

Twistlocks:Hydraulic los yog hluav taws xob ua haujlwm pins uas txuas ntxiv thiab thim rov qab los koom nrog lub kaum sab xis ntawm lub thawv xa khoom.

Telescopic Mechanism:Tso cai rau tus neeg kis tau los kho nws qhov ntev los tuav 20ft, 40ft, thiab 45ft ntim.

Kev taw qhia System:Cov nta qhia (funnels) thiab cov sensors los pab ua kom cov kab sib kis nrog lub thawv tau txais.

Ntsuas qhov system:Feem ntau suav nrog ua - hauv cov sensors los ntsuas qhov hnyav ntawm lub thawv.

3. Gantry Travel System (Crane Propulsion)

Qhov system no txav tag nrho cov crane raws txoj kev khiav.

End Trucks:Cov rooj sib txoos hauv qab ntawm txhua ceg uas muaj cov log tsheb, qag, bearings, thiab tsav tsheb.

Cov log tsheb:Ntau lub log loj, forged steel ib lub tsheb kawg kom faib cov crane qhov hnyav hnyav rau ntawm txoj hlua.

Gantry Tsav Motors:Lub zog hluav taws xob muaj zog uas muab lub zog txav mus rau cov qauv crane loj.

Gantry Reducers (Gearboxes):Txo lub cev muaj zog mus rau qhov yuav tsum tau lub log ceev.

Gantry Brakes:Caij nplooj ntoos hlav- teem nres nres thiab tuav lub crane nyob rau hauv txoj hauj lwm.

4. Rail thiab Runway System

Qhov chaw ruaj khov uas coj thiab txhawb nqa crane.

Txoj Kev Rails:hnyav heev -cov haujlwm steel rails (piv txwv li, QU100, QU120 cov qauv) uas tau ua raws nraim thiab grouted rau hauv lub hauv paus loj loj. Lub hauv paus no yog qhov tseem ceeb rau kev tuav cov dynamic loads thiab xyuas kom meej kev mus los.

Rail Clips thiab Baseplates:Ruaj ntseg ntawm txoj kev tsheb ciav hlau mus rau lub pob zeb hauv paus beam.

5. Hluav taws xob thiab tswj qhov system

Lub paj hlwb uas muaj hwj chim thiab hais kom tag nrho cov haujlwm cranes, feem ntau nrog rau qib siab ntawm automation.

Qhov zoo ntawm Thawv Ob Chav Girder Gantry Cranes

Kev tsim qauv ob chav girder muab cov txiaj ntsig tseem ceeb tshaj ib tus qauv girder, tshwj xeeb tshaj yog rau kev xav tau ntawm kev tuav lub thawv.

1. Superior Lifting Capacity thiab Qhov siab:

Hnyav Loads:Ob chav girders tuaj yeem txhawb nqa lub peev xwm ntau dua, feem ntau yog li ntawm 20 tons mus rau ntau tshaj 100 tons, yooj yim tuav tag nrho 20', 40', 45', thiab txawm 53' thawv.

Greater Hook Qhov siab:Tus tsim tso cai rau lub hoist thiab trolley muab tso rau hauv nruab nrab ntawm lub girders, maximizing lub nqa qhov siab nyob rau hauv tus nuv. Qhov no yog qhov tseem ceeb rau stacking ntim ntau qhov siab.

2. Enhanced Durability thiab Structureal Integrity:

Ob lub girders tsim ib lub qauv ruaj khov thiab ruaj khov uas tuaj yeem tiv taus qhov kev ntxhov siab siab ntawm kev nqa, txav, thiab ntim cov thawv hnyav. Lawv tsis yooj yim rau deflection (khoov) dua li ib leeg girder cranes, uas yog ib qho tseem ceeb rau precision thiab kev nyab xeeb.

3. Txhim khu kev ruaj ntseg thiab kev nyab xeeb:

Lub hauv paus dav dua thiab dual -girder kev tsim kho muab kev ruaj ntseg zoo tiv thaiv sab rub thiab torsional (twisting) rog, tshwj xeeb tshaj yog tseem ceeb hauv cov huab cua sab nraum zoov xws li cov chaw nres nkoj. Qhov no txo ​​qhov kev pheej hmoo ntawm kev thauj khoom sway thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm tag nrho.

Cov cranes no tuaj yeem ua tau nrog cov spans loj heev, npog ntau txoj kab tsheb thauj mus los (xws li, 6+1 lossis ntau dua) thiab kev tsheb ciav hlau. Lawv ua kom qhov chaw ntsug ntsug ntau tshaj plaws los ntawm kev tso cai rau kev sib tw siab thaum tawm hauv av kom meej rau lub tsheb thauj khoom thiab cov tsheb thauj mus los.

5. Versatility nyob rau hauv daim ntawv thov:

Lawv tuaj yeem nruab nrog ntau lub tshuab sib kis los tswj cov thawv ntim sib txawv thiab hom (tus qauv, qhib- sab saum toj, tub yees) thiab txawm tias lwm yam khoom thauj uas siv tus nuv txuas. Qee tus tuaj yeem nqa ob lub 20- ko taw ntim ib txhij (twin-lifter spreader).

6. Kev ua haujlwm siab thiab tsim khoom:

Nruab nrog cov hoists thiab trolleys muaj zog, cov cranes no muaj kev mus ncig siab thiab nqa ceev, ua kom ceev ceev thauj khoom / tshem tawm cov nkoj, tsheb ciav hlau, thiab tsheb thauj khoom. Qhov kev ceev no yog qhov tseem ceeb rau kev ua kom tau raws li lub sijhawm thauj khoom nruj.

7. Customization thiab Automation:

Lawv yog cov customizable heev nrog nta xws li:

GPS Positioning:Rau qhov tseeb trolley thiab gantry txav.

Anti-Sway Systems:Txhawm rau txo qis lub viav vias kom nrawm dua.

Chaw taws teeb tswj lossis Full Automation:Tso cai rau kev khiav hauj lwm los ntawm lub cabin lossis chav tswj, txhim kho tus neeg teb xov tooj ergonomics thiab kev nyab xeeb. Automated Stacking Cranes (ASCs) yog ib qho kev pom nyob rau hauv niaj hnub terminals.

8. Txo qhov ntev -Cov nqi khiav lag luam:

Thaum thawj zaug peev yog siab dua rau cov cranes me, lawv cov kav ntev, kev cia siab, thiab cov khoom siv siab ua rau tus nqi qis dua ib lub thawv txav mus rau lub crane lub neej.

Daim ntawv thov ntawm Thawv Ob Chav Girder Gantry Cranes
