Nyob hauv tus txheej txheem ntawm kev ua haujlwm ntawm chaw tsim khoom siv rau ntau lub hom phiaj, kev tsim kho thiab chaw nres tsheb, cov chaw thau khoom muaj kev nyab xeeb thiab nyab xeeb rau kev txav khoom yog qhov tseem ceeb. Rau cov khoom siv zoo li no, tsis hais txog tus yam ntxwv twg, lub log kom tsim nyog.
Yuav tsum muaj log
Niaj hnub nimno muaj log yuav tsum muaj raws li nram no:
- sijhawm sijhawm ntev ntawm kev ua haujlwm;
- hnav-resistant txheej;
- tsis kam mus rau kev siv tshuab, tshuaj thiab kub;
- nqa lub peev xwm;
- yooj yim ntawm hloov.
Cov khoom lag luam yuav tsum muaj kev nyab xeeb rau kev siv rau txhua qhov chaw, yooj yim rau siv sab hauv chaw ua haujlwm hauv tsev lag luam thiab hauv qhov chaw qhib cua.
Kev nqa tau ntawm cov log tsheb yog tsawg kawg 40 kg, thiab cov khoom lag luam tshwj xeeb tau tsim rau qhov siab tshaj plaws ntawm 110 kg.
Hom ntawm cov log
Raws li lub hom phiaj ua haujlwm, cov log tsheb muaj kev lag luam tau muab faib rau cov hom hauv qab no:
- chaw rau khoom;
- kev tsim kho;
- chaw kuaj ntshav;
- kev lag luam;
- kev ua lag luam;
- kho mob;
- chaw ua haujlwm.
Cov neeg tsim khoom lag luam niaj hnub tsim cov log hauv qab no rau cov cuab yeej siv:
- txuj;
- pneumatic (tshuab nrawm);
- hnyav-ua haujlwm;
- cov khoom lag luam me diam (rau chaw ua haujlwm thiab rooj tog hauv tsev).
Tsis tas li ntawd, kev lag luam log tau ua haujlwm raws li hom kev txuas. Ua raws li cov txheej txheem siv, koj tuaj yeem xaiv ib qho kev xaiv tsis muaj qhov nrawm, nrog fastening ntawm lub ntsia liaj qhov rooj thiab ntawm lub platform.
Log ntug khoom
Raws li qhov ntsuas ntawm qhov siv ntawm cov log tsheb, thaum xaiv lawv, koj yuav tsum them sai sai rau cov khoom ntawm lub npoo. Hauv kev tsim cov log tsheb zoo rau kev siv tshuab, cov hauv qab no yog siv rau kev tsim khoom ntawm rims:
- cam khwb cia hlau;
- cov roj hmab elastic;
- tawv hnyav-muaj zog roj hmab;
- polypropylene;
- nylon;
- polyurethane;
- polyamide.
Yuav ua li cas xaiv cov log siv log
Thaum xaiv cov log tsheb muaj zog, nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus lej li nram no:
- qhov siab tshaj plaws nqa tau;
- lub xub ntiag ntawm kev sib hloov cav;
- cov khoom siv ntawm kev tsim khoom;
- hom phiaj txuj ci;
- fastening hom;
- cov yam ntxwv ntawm thaj chaw ua haujlwm rau cov khoom lag luam no tau npaj tseg.
Txog kev siv tshuaj lossis kev ua haujlwm kub, nws raug nquahu kom xaiv cov log tsheb kom zoo rau daim ntawv thov tsim nyog.
