Amasandugu yo gukwiragiza arangwa n’ubunini bwayo buto, ukworoha gushirwako, ubuhinga budasanzwe, ahantu hahoraho, uburyo bwihariye bwo gutunganya, be n’ukuntu ahantu hashobora gukoreshwa ata n’umwe abujijwe. Zikoreshwa cane, zishikamye kandi zishobora kwizigirwa, zikora neza cane kandi ntizibangamira ibidukikije. Bikora nk’ikibanza co kugenzura ugusangira ubushobozi mu buryo bubereye hagati y’ibice bitandukanye biri mu murongo w’amashanyarazi. Bituma ubushobozi bwo mu mazi bushobora kwakirwa neza no gutanga ubushobozi ku mizigo, kandi ni ngirakamaro kugira ngo abakoresha banyurwe n’uburyo bwo gutanga ubushobozi. Kunoza ubushobozi bwo gukora neza bw’amasandugu yo gutanga amashanyarazi ni intumbero nyamukuru y’ubuhinga bwiza.
Amasandugu yo gukwiragiza akoreshwa mu gukwiragiza ubushobozi mu buryo bubereye no kworohereza guhindura umurongo. Bitanga urugero rwo hejuru rw’uburinzi kandi vyerekana mu buryo busanzwe uko umuzunguruko ugenda.
