Ikhreyini yenqanawe sisixhobo kunye noomatshini bokulayisha kunye nokothula iimpahla ezibonelelwa yinqanawe, ingakumbi isixhobo se-boom, i-crane yedekhi kunye nabanye oomatshini bokulayisha kunye nokothula.
Kukho iindlela ezimbini zokulayisha kunye nokukhulula iimpahla ngesixhobo se-boom, oko kukuthi ukusebenza ngentonga enye kunye nokusebenza ngentonga ephindwe kabini.Ukusebenza ngentonga enye kukusebenzisa i-boom ekulayisheni nasekukhupheni iimpahla, i-boom emva kokuphakamisa iimpahla, ukutsala umtya ukuze iimpahla nge-boom zijiwule ngaphandle kwebhodi okanye i-cargo hatch, emva koko ubeke phantsi iimpahla, emva koko ujike i-boom. ubuyela kwindawo yokuqala, ngoko uhambo lokuya nokubuya umsebenzi.Ukulayisha kunye nokukhulula ixesha ngalinye ukusebenzisa i-rope swing boom, amandla aphantsi kakhulu, ukuqina kwabasebenzi.Ukusebenza ngentonga ephindwe kabini, enye ibekwe phezu kwe-hatch ye-cargo, enye i-outboard, i-booms ezimbini ngentambo egxininiswe kwindawo ethile yokusebenza.Iintambo zokuphakamisa iibhomu ezimbini zixhunyiwe kwikhonkco efanayo.Kufuneka kuphela ukufumana kunye nokubeka iintambo ezimbini zokuqalisa ngokulandelelana, unokothula iimpahla ukusuka kwinqanawa ukuya kwi-pier, okanye mhlawumbi ulayishe iimpahla ukusuka kwi-pier ukuya kwinqanawa.Amandla okulayisha kunye nokukhupha i-double-rod operation iphezulu kunomsebenzi wentonga enye, kwaye ubuninzi bokusebenza bulula.
