iyahlula kwaye ihlukanise iimveliso zekhonkrithi ukufumana umphumo wendalo wendalo. Isixhobo sisetyenziswa ngokubanzi kunyango olukwinqanaba eliphezulu lodonga olomileyo lokhuselo lweperipheral yolwakhiwo lwembonakalo-mhlaba, kunye nokulungiswa kogcino lwamanzi, ihydraulic kunye neemveliso zegadi zikamasipala. Iibhloko ezinokwahlulwa kubandakanya zonke iintlobo zebhloko yodonga lwekhonkrithi, iipavers, kunye neentlobo ezahlukeneyo zebhloko yekhonkrithi esetyenziselwa iipaki, izikhululo zeenqwelomoya, iiwharfs kunye nezinye iindawo ezinje ngezitena zehydraulic, izitena zokugcina, izitena zentyatyambo, izitena zocingo, njl.
