Qhov no yog ib qho tshwj xeeb crane uas txhua qhov ib feem tsim, hloov kho, los yog kaw nrog ib lub hom phiaj tseem ceeb: los tiv thaiv ignition nyob rau hauv ib puag ncig uas flammable gases, vapors, plua plav, los yog fibers.

Cov khoom tuaj yeem raug cais los ntawm lawv qhov kev tawg tseem ceeb - pov thawj kev hloov kho:

1. Cov Qauv & Mechanical Cheebtsam (Tsis yog-Kev hloov pauv)

Cov khoom siv no raug hloov kho kom tsis txhob muaj hluav taws xob los ntawm kev sib txhuam lossis kev cuam tshuam.

Lub Npe Lub Npe (2):Standard ob lub thawv girders. Txawm hais tias tsis muaj kev pheej hmoo hluav taws xob ncaj qha, lawv muab cov ncej muaj zog uas txhawb nqa tag nrho cov khoom tiv thaiv.

Hook & Hook Block:Ua los ntawm cov hlau uas tsis yog-tshuaj hlau xws li tooj liab, beryllium tooj liab, lossis txhuas-bronze alloys. Qhov no tiv thaiv sparks yog hais tias tus nuv yuam kev ntaus lwm yam khoom hlau.

Log (Trolley & Choj Ncig Tebchaws):

Kev xaiv 1:Log nrogtsis yog-sparking rims(piv txwv li, bronze rims) nias rau ntawm lub hub steel.

Kev xaiv 2:Tag nrho cov log ua los ntawm cov khoom tsis yog -twb.

Brake Systems:

Nres Discs / Nruas:Ua los ntawmtsis yog-cov hlau nplaum.

Comprehensive Protection:Kev nyab xeeb tsis yog ib qho ntxiv -rau tab sis yog tsim rau hauv tag nrho cov qauv, los ntawm tsis yog - cov khoom siv hluav taws xob rau cov tshuab hluav taws xob kaw.

2. Kev Tswj Xyuas Kev Ua Raws Cai thiab Kev Txom Nyem

Ua tau raws li cov qauv nruj:Nws yog tsim thiab ntawv pov thawj kom ua raws li cov txheej txheem thoob ntiaj teb nruj rau cov chaw muaj kev phom sij (xws li ATEX hauv Europe, NEC / NEMA hauv North America, IECEx thoob ntiaj teb). Qhov no tso cai rau cov lag luam ua haujlwm raug cai hauv cov lag luam muaj kev pheej hmoo siab -.

Txo Liability:Kev siv cov cuab yeej siv tau ntawv pov thawj txo qis lub tuam txhab txoj cai thiab kev lav phib xaub nyiaj txiag thaum muaj xwm txheej.

3. Kev ua haujlwm tsis cuam tshuam hauv cov txheej txheem tseem ceeb

Enables Production:Ntau cov txheej txheem hauv tshuaj, tshuaj, lossis cov nroj tsuag pleev xim tsis tuaj yeem ua haujlwm yam tsis muaj kev txhawb nqa. QB crane ua rau nws muaj kev nyab xeeb los txuas ntxiv cov haujlwm no yam tsis muaj kev kaw haujlwm los ntawm cov khoom siv tsis zoo.

Kev ntseeg siab:Cov khoom siv hauv kev tawg- cov qauv pov thawj yog qhov muaj zog dua, ruaj khov, thiab feem ntau muab kev tiv thaiv ntau dua (IP kev ntsuas) tiv thaiv plua plav thiab ya raws, ua rau muaj kev ua haujlwm ntau dua thiab txo qis qis.

4. Ntev-Cov Nqi Them Nqi Zog

Tiv thaiv kev puas tsuaj loj:Tus nqi ntawm ib qho kev tawg dwarfs qhov pib nqis peev ntau dua hauv kev tawg - pov thawj crane. Nws yog ib qho kev nqis peev hauv kev tiv thaiv cov cuab yeej cuab tam.

Durability:Ua nrog corrosion-cov ntaub ntawv tiv taus thiab cov khoom siv zoo tshaj, cov cranes no muaj lub neej ua haujlwm ntev txawm tias nyob rau hauv qhov hnyav, corrosive ib puag ncig uas muaj kev ua tshuaj lom neeg.

5. Kev tiv thaiv ib puag ncig

Tiv thaiv kom tsis txhob muaj cov tshuaj lom lossis cov khoom tawg yooj yim rau hauv ib puag ncig uas tuaj yeem tshwm sim los ntawm qhov tshwm sim ignition.
