Ukupakisha kunye nokuHanjiswa

1. Ukupakisha:Intambo yentsimbi ukuze kube lula ukuyiphatha.
Iibhloko zomthi okanye i-dunnage zibekwe phakathi kweenqwaba ukuze kuthintelwe umonakalo ngexesha lokuthuthwa.
Ukukhusela umphezulu (ukhetho): Ipeyinti emnyama, ioyile yokuthintela umhlwa, okanye imiqulu yefilimu yeplastiki.
Iingqumba ze-galvanized ezifakwe kwi-hot-dip zinokuba nefilimu yokukhusela okwethutyana ukuthintela imikrwelo yomphezulu.
Ukupakisha okwenziwe ngokwezifiso kuyafumaneka xa kuceliwe.

2. Ukuhanjiswa:Ubude besitokhwe esiqhelekileyo: iimitha ezi-6 kunye neemitha ezili-12. Ubude obulungiselelwe wena buyafumaneka ukuze kuhlangatyezwane neemfuno zakho zeprojekthi.
Ifanelekile ukuthutha ngolwandle, ngololiwe, okanye ngendlela.
Ixesha lokuhanjiswa lidla ngokuba ziintsuku ezili-15-30 emva kokuqinisekiswa kwentlawulo, kuxhomekeke kubungakanani kunye neenkcukacha.
Ifanelekile ukuthunyelwa kwamanye amazwe kwihlabathi liphela, kunye neseti epheleleyo yamaxwebhu (isatifikethi sokuhlolwa, uluhlu lokupakisha, i-bill of lading).

3. Ukuphatha Amanyathelo Okhuseleko:Sebenzisa i-crane okanye i-forklift exhotyiswe ngee-sling okanye ii-sling ukuthintela ukuguquka kwemibhobho.
Gcina kwindawo epholileyo, eyomileyo, nengena umoya kakuhle ukuze ingagqwali ngaphambi kokuba uyifake.
Kwimithwalo emikhulu/enzima kakhulu, nceda ulandele imigaqo yokuthunyelwa kwempahla yasekuhlaleni.
