Ukupakisha kunye nokuHanjiswa

1. Ukupakisha:Iintambo zentsimbi ukuze kube lula ukuziphatha. Iibhloko zomthi okanye i-dunnage zifakwa phakathi kwezi ngqokelela ukuze zikhuseleke ekonakaleni ngexesha lokuthuthwa. Unyango lomphezulu (ukhetho): Ipeyinti emnyama, ioyile yomhlwa, i-roll yefilimu yeplastiki. Iinqwaba ze-hot dip galvanized zinokugqunywa ngefilimu yokukhusela umphezulu okwethutyana. Singabonelela nangokupakishwa okwenziwe ngokwezifiso.

2. Ukuhanjiswa:Ubude obuqhelekileyo bestoke: 6m, 12m. Ubude obulungiselelwe wena ukuze buhambelane neprojekthi yakho. Ifanelekile ukuthuthwa ngolwandle, ngoololiwe nasendleleni. Ixesha lokuqalisa imveliso lidla ngokuba ziintsuku ezili-15-30 emva kokuba intlawulo ifunyenwe, ukuhanjiswa kwangoko emva kobungakanani kunye neenkcukacha. Ifanelekile ukuthunyelwa kwamanye amazwe kwihlabathi liphela kunye namaxwebhu apheleleyo (isatifikethi sokuhlolwa, uluhlu lokupakisha, i-bill of lading).

Amanyathelo okuthintela:

1. I-crane okanye i-forklift enezilayingi okanye izihlangu zesilayingi kufuneka isetyenziswe ukuthintela ukuguquka kombhobho kwi-Handing Peoperties.

2. Gcina indawo epholileyo, eyomileyo nengena umoya ukuze ugcine, kungenjalo kuya kubakho ukugqwala ngaphambi kokufakwa. Kwiipakethe ezinkulu/ezinobunzima obugqithisileyo, nceda ulandele ngokungqongqo ummiselo wokuthunyelwa kwempahla kwindawo yakho.
