Ikhonkco le-alloy le-China Grade 80 elisemgangathweni olungileyo le-Hoist/G80 Lifting Chain (EN 818-7)
Ukuze siqhubeke siphucula inkqubo yolawulo ngokwemigaqo ethi “ngokunyaniseka, ukholo oluhle kunye nomgangatho ziziseko zophuhliso lweshishini”, sifumana ngokubanzi intsingiselo yeemveliso ezinxulumene nazo kwihlabathi liphela, kwaye sihlala siphuhlisa iimveliso ezintsha ukuhlangabezana neemfuno zabathengi zeChain ye-Alloy ye-China Grade 80 esemgangathweni ophezulu ye-Hoist/G80.Ikhonkco Lokuphakamisa(EN 818-7), Siyakukhuthaza ukuba uqhagamshelane nathi njengoko sifuna abahlobo kwishishini lethu. Siqinisekile ukuba uza kufumanisa ukuba ukusebenzisana nathi akupheleli nje ekuveliseni iziqhamo kodwa kunenzuzo. Sikulungele ukukunika into oyifunayo.
Ukuze siqhubeke siphucula inkqubo yolawulo ngokwemigaqo ethi “ngokunyaniseka, ukholo oluhle kunye nomgangatho ziziseko zophuhliso lweshishini”, sifumana ngokubanzi intsingiselo yeemveliso ezinxulumene nazo kwihlabathi liphela, kwaye sihlala siphuhlisa iimveliso ezintsha ukuhlangabezana neemfuno zabathengi.Ikhonkco laseTshayina, Ikhonkco Lokuphakamisa, Kwiminyaka engaphezu kweshumi yamava kule fayili, inkampani yethu ifumene udumo olukhulu ekhaya nakwamanye amazwe. Ngoko ke samkela abahlobo abavela kwihlabathi liphela ukuba beze kuqhagamshelana nathi, kungekuphela nje ngeshishini, kodwa nangobuhlobo.
