Dziko la ma elevator likusintha nthawi zonse kuti zitsimikizire chitetezo, kudalirika, komanso mphamvu zamagetsi. Ma braking resistors akugwira ntchito yofunika kwambiri popanga masinthidwewa, ndikupereka njira zatsopano zothanirana ndi ma elevator. Monga ma elevator amayenda pafupipafupi komanso kutsika, kufunikira kwa mabuleki odalirika kumakhala kofunika kwambiri. Ma braking resistors ali patsogolo pothana ndi vutoli, kupereka ntchito zofunika pakuwongolera liwiro, kuwonetsetsa kuyimitsidwa kosalala, komanso kupewa kung'ambika kwambiri pazigawo za elevator.
Chimodzi mwazofunikira za ma braking resistors mu elevator ndi regenerative braking. Elevator ikatsika kapena kutsika, imatulutsa mphamvu ya kinetic yochulukirapo. M'malo motaya mphamvuyi monga kutentha, makina opangira mabuleki osinthika amawagwiritsa ntchito ndikusandutsa mphamvu yamagetsi. Ma braking resistors amagwira ntchito yofunika kwambiri pakuyamwa ndi kuwononga mphamvu zotsalazo, zomwe zimathandiza kuti mphamvu zisamawonongeke komanso kuti chilengedwe chisamawonongeke. Poyimitsidwa mwadzidzidzi, amathandizira kuyimitsa chikepe mwachangu komanso mosatetezeka, kuchepetsa zoopsa zomwe zingachitike ndikuwonetsetsa kuti okwera ali otetezeka.
Kuphatikiza pa chitetezo ndi mphamvu zamagetsi, zoletsa ma braking zimathandizanso kukulitsa moyo wa zida za elevator. Pochepetsa kupsyinjika kwa makina ndi magetsi panthawi ya braking, amathandizira kuchepetsa zofunikira zokonzekera ndikuwonjezera kudalirika kwa ma elevator. Kukula kwa ma compact, resistors ochita bwino kwambiri kumathandizira kuphatikizana kosagwirizana ndi ma elevator amakono, kukhathamiritsa kagwiritsidwe ntchito ka malo pomwe akupereka magwiridwe antchito.
