Ukupakisha kunye nokuHanjiswa

1. Ukupakisha:

Iibhloko zomthi okanye i-dunnage zisetyenziswa phakathi kweengqimba zeengxowa zokupakisha okanye izikhongozeli ukuthintela umonakalo ngexesha lokuthuthwa.

Unyango lomphezulu (ukhetho): Ipeyinti emnyama, ioyile yokuthintela umhlwa, okanye imiqulu yeplastiki.

Iingqumba ze-galvanized ezifakwe kwi-hot-dip zingagqunywa ngefilimu yokukhusela yexeshana ukuthintela ukukrweleka komphezulu.

Ukupakisha okwenziwe ngokwezifiso kuyafumaneka.

2. Uthutho:

Ubude bokugoba kwesitokhwe: iimitha ezi-6, iimitha ezili-12. Ubude obungengobuqhelekileyo buyafumaneka xa kucelwe iprojekthi.

Ifanelekile ukuthutha ngolwandle, ngololiwe, okanye ngendlela.

Ixesha lokuhambisa lidla ngokuba ziintsuku ezili-15-30 emva kokufumana intlawulo, kuxhomekeke kuhlobo lwemveliso kunye neenkcukacha zayo.

Ifanelekile ukuthunyelwa kwamanye amazwe kwihlabathi liphela, kunye neseti epheleleyo yamaxwebhu (isatifikethi sokuhambelana nemithetho, uluhlu lokupakisha, i-bill of lading).

3. Ukuphatha Amanyathelo Okhuseleko:

Bopha imibhobho ngokukhuselekileyo usebenzisa i-crane okanye i-forklift exhotyiswe ngee-slings okanye ii-slings ukuthintela ukuguguleka.

Gcina imibhobho kwindawo eyomileyo, enomoya, nepholileyo ngaphambi kokuba uyifake ukuze uthintele ukugqwala.

Ukuthunyelwa kwempahla enkulu/enzima kakhulu kufuneka kuhambelane nemigaqo yothutho lwasekuhlaleni.
