Cov lus piav qhia ntxaws

Qhov no galvanized crane khiav beam (crane girder) yog kab rov tav cov tswv cuab uas ib qho nyiaj siv ua haujlwm gantry crane taug kev - nqa qhov hnyav ntawm tus choj crane, hoist, trolley, thiab lifted load. Tsis zoo li cov qauv tsim qauv tsim los rau cov khoom siv hluav taws xob zoo li qub, lub crane runway beam yuav tsum tiv thaiv kev rov ua haujlwm ntawm lub crane hla dhau (kev qaug zog), lateral quab yuam los ntawm crane acceleration thiab braking, thiab cuam tshuam los ntawm kev thauj khoom thiab tso tawm. Cov kab teeb pom kev yog ib qho ua tau - ntu welded (los yog ob qho kuv- kab teeb sib koom sab - los ntawm -} sab) nrog lub phaj tuab tuab kawg ntawm lub ntsej muag pem hauv ntej, featuring 8 siab - lub zog hexagonal bolts (2 × 4 qauv) txuas mus rau pawg txhawb nqa. Daim duab peb sab gusset phaj yog welded rau sab ntawm lub nqaj nyob ze ntawm qhov kawg, muab ntxiv shear muaj peev xwm thiab ua hauj lwm raws li ib qho kev sib txuas. Ntxiv gussets yog pom nyob rau hauv lub beam ntev, nyob rau hauv lub sij hawm tsis tu ncua kom nruj lub web tiv thaiv concentrated log loads los ntawm lub crane kawg tsheb. Kev sib dhos ua tiav yog kub-dip galvanized rau ISO 1461 (70{17}}100μm), muab kev saib xyuas tsis muaj kev tiv thaiv corrosion hauv kev lag luam ib puag ncig uas cranes feem ntau ua haujlwm. Crane runway beams yog tsim los ntawm Q355B lossis Q390B steel rau lawv lub zog ntau dua thiab qaug zog. Peb tsim txhua txoj kab hluav taws xob rau AISC 360, AISC Design Guide 7 (Industrial Buildings), lossis Eurocode 3 Part 6 (Crane Supporting Structures), suav nrog kev suav lub neej qaug zog rau cov chav kawm kev pabcuam crane (CMAA Class A txog F). Txhua txoj kab ciav hlau tau dhau los ua qhov kev soj ntsuam UT tag nrho, kev txheeb xyuas qhov ntev, thiab camber / straightness check ua ntej xa khoom. Beams raug xa mus nrog kev tsheb ciav hlau mounting kho vajtse, bolted splice cov khoom siv rau kev sib koom ua ke ntawm txoj kev khiav, thiab crane rail alignment tolerances kom meej meej teev nyob rau hauv phau ntawv erection.

Yam khoom

Cov ntsiab lus muag khoom

Kev qaug zog- cov ntsiab lus tsim nyog: Cov khoom txuas txuas (gussets, stiffeners, rail clips) yog cov ncauj lus kom ntxaws nrog cov kev hloov pauv hloov pauv, hauv av weld ntiv taw, thiab tsis muaj kev sib hloov welds ntawm nro flanges - tag nrho rau AISC 360 Cov Ntawv Ntxiv 3 pawg qaug zog

Crane rail alignment tseem ceeb: Peb cov kab hluav taws xob yog tsim nrog camber kam rau ua ntawm L / 1000 siab tshaj plaws thiab cheb kam rau L / 1000 siab tshaj - nruj dua li cov qauv kev teeb pom kev zoo - vim tias cov crane rail kev sib raug zoo cuam tshuam ncaj qha rau crane log hnav thiab hoist trolley taug qab

Bolted runway splices: Runway beam segments yog koom nrog bolted flange thiab web splice daim hlau - tsis muaj qhov vuam ntawm txoj kev khiav txhais tau tias tsis muaj ncej-splice rail re-alignment vim weld distortion

Qhov kawg nres cuam tshuam tsim: Peb muab cov crane kawg nres (tsis nres) kev sib txuas rau hauv lub nqaj kawg nthuav dav, nrog cov nres nres bolted mus rau sab saum toj flange thiab ntxiv dag zog nrog lub welded shear block - kuaj rau lub crane tag nrho - ceev cuam tshuam lub zog

Ua kom tiav cov ntaub ntawv pob: Txhua lub crane beam nkoj nrog daim ntawv pov thawj zeb, vuam daim ntawv qhia nrog NDT traceability, qaug zog tsim kev suav cov ntsiab lus, thiab ib daim ntawv teev cov kab ke kev sib haum xeeb rau lub site engineer's kos npe -tawm

Lub tuam txhab zoo

Crane beam tshwj xeeb: Peb pab pawg neeg ua haujlwm crane khiav haujlwm tau xa cov kab teeb rau 5-100+ tuj nyiaj siv ua haujlwm cranes hla steel mills, shipyards, thiab cov khw muag khoom hnyav thoob ntiaj teb

Kev qaug zog engineering: Txhua lub crane nqaj tsim suav nrog kev ntsuas lub neej qaug zog raws li cov chav kawm kev pabcuam crane tau teev tseg - peb tsis yog qhov loj me rau lub zog, peb txheeb xyuas cov ncauj lus nthuav dav ntawm cov khoom sib txuas ua tau raws li qhov yuav tsum tau ua.

Galvanized nrog kev saib xyuas: Crane beams yog galvanized tom qab tiav fabrication; peb 12.5m da dej tuav cov nqaj ntu hauv ib qho dips, thiab peb tswj cov cua txias kom tswj tau qhov ± L / 1000 ncaj nraim yuav tsum tau ua rau crane rail kev sib dhos

Ua kom tiav pob kev khiav: Peb muab cov kab teeb, kev tsheb nqaj hlau (nrog clips thiab cov ntaub qhwv), qhov kawg nres, kem brackets, thiab longitudinal khi -rov qab - tag nrho txoj kev khiav los ntawm ib qhov chaw

Laser alignment verification: Txhua lub beam raug tshuaj xyuas rau cheb (kab rov tav ncaj) thiab camber ( ntsug ncaj) nrog lub laser tracker - tseem ceeb vim hais tias lub crane rail kam rau ua yog feem ntau ± 2mm hauv 10m

Cov lus nug nquag nug (FAQ)

Q1: Dab tsi crane pab pawg (CMAA) ua koj cov kab hluav taws xob khiav?

A: Peb tsim thiab tsim cov kab hluav taws xob khiav rau txhua chav CMAA: Chav A (standby / tsis tshua muaj) los ntawm Chav F (kev pabcuam hnyav txuas ntxiv). Cov chav kawm kev pabcuam txiav txim siab qhov kev xav tau ntawm kev qaug zog - Chav Kawm C thiab saum toj no yuav tsum muaj kev qaug zog ntawm lub neej suav nrog cov kev ntsuas tshwj xeeb thiab kev ntsuas kev puas tsuaj ib puag ncig AISC 360 Cov Ntawv Ntxiv 3. Peb mam li nug koj cov chav pabcuam crane thiab thauj khoom spectrum thaum lub sijhawm nug.

Q2: Koj ua li cas kom ntseeg tau tias lub flange sab saum toj ncaj txaus rau crane rail mounting?

A: The crane rail requires straightness of ±2mm in any 2m length (per CMAA 70). We achieve this through: (1) controlled cooling after welding and galvanizing to minimize distortion, (2) laser tracker measurement of sweep and camber on every beam, (3) flame straightening of any deviation >L / 1500 ua ntej kev soj ntsuam zaum kawg. Peb muab daim ntawv qhia kev ntsuas qhov ncaj nrog txhua lub teeb.

Q3: Koj puas tuaj yeem muab cov crane rail thiab mounting hardware thiab?

A: Yog. Peb tuaj yeem muab cov kev tsheb ciav hlau ua tiav: crane rail seem (A-series ib DIN 536 lossis JIS sib npaug), rail pads (rubber lossis polyurethane), bolted rail clips, thiab rail splice tuav. Txoj kev tsheb ciav hlau yog xoob- xa mus rau qhov chaw teeb tsa lossis ua ntej- mounted thiab ua raws li cov nqaj hauv peb lub khw (rau cov kab teeb luv uas tuaj yeem thauj tau tiav). Khw ua ntej-mounting tshem tawm txoj kev tsheb ciav hlau ua haujlwm ntawm qhov chaw.

Q4: Dab tsi yog qhov txawv ntawm lub crane khiav beam thiab lub teeb lub tsev tsis tu ncua?

A: Crane runway beams txawv ntawm cov kab hluav taws xob niaj hnub hauv plaub txoj hauv kev tseem ceeb: (1) Kev qaug zog - rov ua dua crane hla yuav tsum qaug zog- tsim nyog cov ntsiab lus weld; tus qauv beam welds yuav tawg nyob rau hauv cyclic loading. (2) Lateral loads - crane surge thiab skew tsim kab rov tav rog uas txheem kab teeb tsis tsim rau. (3) Kev nruj - ntsug deflection txwv yog nruj dua (L / 600 txog L / 1000 vs L / 240 rau pem teb) los tiv thaiv crane trolley drift. (4) Torsion - eccentric rail load twists lub nqaj; Cov kab hluav taws xob khiav yuav tsum muaj qhov nruj txaus torsional los yog ib qho kev txwv sab nraud. Peb cov kab hluav taws xob crane nyob rau tag nrho plaub yam.
