Tam sim no, cov hlua hlau, uas muaj cov oval (puab) txuas txuas los ntawm lub tshuab vuam, tau txais kev nrov nrov ntawm ntau yam fasteners. Qhov laj thawj rau qhov kev thov yog ntau lub hom phiaj. Lawv tuaj yeem siv rau kev siv hauv tsev thiab kev lag luam. Nyob ntawm lub hom phiaj, cov chains tau muab faib ua kev lag luam thiab kev lag luam. Raws li txoj cai, round-links chains yog siv rau kev txav, tuav, dai loads, nrog rau hauv cov txheej txheem load-gripping hauv daim ntawv ntawm cov khoom sib cais.
Cov saw hlau yog siv rau ntawm qhov chaw tsim kho, tsev khaws khoom, khw muag khoom, cov koom haum thauj. Ib txoj hauv kev siv chains yog dai cov hooks ntawm lub tshuab nqa loj.
Raws li cov duab ntawm qhov txuas, cov hlau txuas tau muab faib ua:
- long links;
- short links.
Cov hlua txuas luv yog hom kev sib tw nrov siv rau kev ncab. Raws liCov kev cai ntawm International Standard DIN 766 (analogous rau 5685A), muaj calibrated thiab uncalibrated. Xws li cov saw hlau yog tsim los ntawm cov tuav ntawm alloyed, carbon, high-alloyed steels ntawm ntau yam diameters thiab muaj ib tug electroplated txheej nyob rau hauv daim ntawv ntawm ib tug txheej ntawm zinc.
Qhov loj ntawm cov saw hlau yog txiav txim siab los ntawm caliber ntawm qhov txuas (inch ntawm seem ntawm tus pas nrig). Cov hlua txuas sib txawv ntawm qhov ntev, dav thiab caliber (inch).
Cov hlua txuas luv luv muaj qhov txuas luv, yog li nws yog tsim los rau kev thauj khoom ntau ntxiv thiab suav tias muaj kev ntseeg siab thiab ruaj khov. Tab sis nws tsis pom zoo kom siv nws los nqa cov khoom thauj. Muab nyob rau hauv coils qhov txhab ntawm cov yas spools los ntawm 10 meters mus rau 60 meters ntev.
Luv txuas txuas. Daim ntawv thov:
- mechanical engineering;
- shipbuilding;
- kev lag luam tsheb;
- warehouse technology;
- kev ua liaj ua teb;
- kev tsim kho sector.
Thaum xaiv ib txoj hlua hlau tshwj xeeb, koj yuav tsum paub cov yam ntxwv hauv qab no:
- breaking load - lub siab tshaj plaws load uas luv-txuas hlau saw tuaj yeem tiv taus ua ntej tsis ua hauj lwm thaum lub sij hawm ntsuas tensile;
- ua haujlwm thauj khoom - qhov loj tshaj plaws uas tuaj yeem dai ntawm cov saw hlau hauv nws cov haujlwm ua haujlwm;
- saw pitch yog qhov ntev ntawm qhov txuas ntawm nws qhov dav tshaj plaws.
Luv txuas txuas. Mounting method
Cov saw hlau raug teeb tsa thaumkev pab cuam ntawm cov khoom siv rigging: carabiners, lanyards, swivels, chain connectors thiab lwm yam kev sib txuas.
Welded luv txuas saw muaj ntau yam kev siv - los ntawm lub teeb tes hom hoists mus rau hnyav nqa cranes. Kev sib txuas los ntawm kev sib cuag pob tw yog tsim los ntawm ib qho kev sib txuas. Tom qab kev tsim khoom, cov saw hlau tau raug kuaj xyuas thiab cov ntaub ntawv pov thawj load. Nws ua haujlwm zoo rau kev ncab thiab muaj qhov cuam tshuam me me. Kev tsim cov saw hlau tso cai rau koj tuaj yeem hloov kho qhov ntev thiab muaj qhov txheeb ze ntawm kev ywj pheej txwv rau ib qho txuas, nrog rau tsim lub voj voog siv txoj kev txuas-rau-txuas.
