Izibopho zizisasazi ezizodwa zokuphakamisa izinto ezigqityiweyo. Iindlela ezahlukeneyo zokuvelisa amandla okubamba zinokwahlulahlulwa zibe ziindidi ezintathu: izibopho ze-lever, izikhonkwane ze-eccentric kunye nezinye izikhonkwane ezinokuhanjiswa.
Amandla nokubotshwa lever uqinisa luveliswa ubunzima eziphathekayo ngokwalo umgaqo lever.Therefore, xa umhlathi emihlathini uhlala rhoqo, amandla nokubotshwa ulingana ubunzima efileyo into ejingayo, ukuze iimpahla zibe nokubotshwa ngokuthembekileyo.
Ukubotshwa amandla eligaqa ome uveliswa self-ubunzima izinto ngokusebenzisa inyathelo self-itshixa phakathi ibhloko eccentric kunye nezinto.
Amandla okubotshwa kolunye uqinisa oluhambisekayo lwenziwa sisixhobo sokujija ngamandla angaphandle, kwaye ayinanto yakwenza nobunzima kunye nobungakanani bezinto.
