Isikhululo samandla enkunkuma sibhekisa kwiziko lamandla obushushu elisebenzisa amandla obushushu akhutshwa ngokutshisa inkunkuma kamasipala ukuvelisa umbane. Inkqubo esisiseko yokuveliswa kwamandla omthwalo iyafana naleyo yokuvelisa amandla obushushu aqhelekileyo, kodwa umgqomo wenkunkuma ovaliweyo kufuneka ufakwe ukuthintela ukungcoliseka kwendalo.
I-crane yokuphatha inkunkuma idlala indima ebalulekileyo kwizityalo zale mihla zokutshisa, apho imigaqo engqongqo yokusingqongileyo isebenza kunye nokuphathwa kwemathiriyeli kufuneka kusebenze ngowona mgangatho uphezulu ukusukela oko inkunkuma ifikayo, njengoko i-crane ipakisha, ilungisa, ixutywa kwaye izisa kwindawo yokutshisa. Ngokwesiqhelo, kukho iikhreyini ezimbini zokuphatha inkunkuma ngaphezulu komngxuma wenkunkuma, enye yazo iyi-backup, ukuqinisekisa ixesha elincinci lokuphumla.
I-SEVENCRANE inokukubonelela ngenkunkuma yokuphatha i-crane yokwandisa ukhuseleko lwakho kunye nemveliso.
