Nyob rau hauv tus txheej txheem ntawm kev yuav ib lub crane, tus thawj coj ua lag luam feem ntau nug qee cov lus nug xws li:
1.Yuav siv pes tsawg teev cov cranes ib hnub twg? los ntawm theem nrab
2.Yuav nqa ntau npaum li cas hauv ib teev los ntawm theem nruab nrab? lwm.
Cov lus nug no tau npaj rau kev xaiv cov cranes. Los ntawm cov lus nug no, tus thawj tswj kev muag khoom xaiv cov kev daws teeb meem crane. Koj yuav tau txais cov lus hais txog crane nrog lub luag haujlwm ua haujlwm cim A5 / M5, A3 / M3, thiab lwm yam. Tej zaum koj yuav xav paub ntau ntxiv txog cov qib no sawv cev li cas? Niaj hnub no, peb yuav piav qhia txog dab tsi lub luag haujlwm ntawm crane hoisting yog dab tsi, nws cuam tshuam li cas, thiab yuav ua li cas los xam thiab xaiv lub luag haujlwm ua haujlwm crane tsim nyog.
Dab tsi yog Crane Hoist Duty Classification?
Crane hoist duty classification pab txiav txim siab npaum li cas thiab hnyav npaum li cas crane tuaj yeem siv tau zoo. Nws ua kom:
Cov cuab yeej siv lub neej ntev dua- Tiv thaiv kom tsis txhob overloading thiab hnav
Kev nyab xeeb zoo dua- Txo kev tawg thiab kev sib tsoo
Tus nqi efficiency- Ua haujlwm zoo ntawm crane rau txoj haujlwm
Kev faib tawm yog nyob ntawm ob yam tseem ceeb:
Load Spectrum- Cov khoom hnyav npaum li cas (Lub teeb rau hnyav heev)
Lub Sijhawm Ua Haujlwm Txhua Hnub (Sijhawm siv) - Muaj pes tsawg teev lub crane ua haujlwm ib hnub
Yuav Ua Li Cas Txiav Txim Load Spectrum
Lub load spectrum yog raws li qhov hnyav npaum li cas lub crane nqa tsis tu ncua:
| Kev faib tawm | Load Hom | Hom Siv Case |
|---|---|---|
| Lub teeb (M3 / 1Bm) | Feem ntau lub teeb loads, qee zaus puv load | Warehouses, chaw ua haujlwm me me |
| Nruab nrab (M4/1Am) | Sib tov ntawm lub teeb thiab nruab nrab loads | Cov chaw tsim kho, factories |
| Hnyav (M5/2m) | Ncua ntim puv, siv hnyav | Steel nroj tsuag, shipyards |
| Hnyav heev (M6+/3m+) | Yuav luag tag nrho cov loads | Mining, kev lag luam hnyav |
Xam cov sijhawm ua haujlwm txhua hnub
Cov mis los nrhiav qhov nruab nrab txhua hnub ua haujlwm yog:
t = (2 × N ×H × T) / (V × 60)
Qhov twg:
N= Lub voj voog ua haujlwm ib teev (piv txwv li, 5 nqa / teev)
H= Qhov nruab nrab nqa qhov siab (meters)
T= Cov sijhawm ua haujlwm txhua hnub (piv txwv li, ua haujlwm 8-teev)
V= Hoisting ceev (meters ib feeb)
Piv txwv xam:
Yog tias muaj lub crane uas load spectrum hnyav, crane nqa 5 zaug / teev (N=5), nruab nrab qhov siab (H=3}m), ua haujlwm 16 teev / hnub (T=16), thiab ceev (V=5} m / min):
t=(2 × 5 × 3 × 16) / (5 × 60) =1.6 teev / hnubt=5 × 602 × 5 × 3 × 16 =1.6 teev/hnub
Qhov no txhais tau hais tias lub crane lub luag hauj lwm chav kawm yogM5 (GB A5 / FEM 2m).
International Duty Class Sib Piv
Ntau lub tebchaws siv cov lej sib txawv:
| ISO/BS/DIN | Tuam Tshoj (GB) | Teb chaws Europe (FEM) | USA (CMAA) |
|---|---|---|---|
| M3 | A3 | 1 Bm ib | A |
| M4 | A4 | 1 am | B |
| M5 | A5 | 2m | C |
| M6 | A6 | 3m | D |

Vim Li Cas Lub Luag Haujlwm Kev faib tawm tseem ceeb?
Kev ua raws li kev nyab xeeb- Zam kev nplua thiab xwm txheej
Kev npaj kho kom zoo dua- Paub thaum twg yuav ua haujlwm crane
Kev txuag nqi- Tsis txhob yuav ntau tshaj -spec crane rau cov haujlwm teeb
