SCIC Qib 70 (G70) thauj chains cargo lashing yog ua raws li NACM cov qauv. Cov hlua txuas tau zoo tsim / saib xyuas vuam & kev kho cua sov kom ntseeg tau cov khoom siv kho tshuab xws li lashing muaj peev xwm, pov thawj quab yuam, tawg quab yuam, elongation & hardness. Kev tshuaj xyuas tag nrho thiab kev sim yog siv rau ntawm cov saw hlau.
G70 Thauj Chains muaj qhov zoo ntawm kev huv, lub teeb yuag, lub zog thiab kev ntseeg tau thiab yog li yog qhov zoo tagnrho rau kev khi-down daim ntawv thov rau cov khoom thauj nrog kev thauj mus los thiab kev lag luam.
Peb tuaj yeem muab cov chains nrog rub hooks thiab lwm yam khoom, raws li cov neeg siv khoom ntev.
