Kapangidwe kapadera kamapangitsa kuti mankhwalawa akhale otetezeka ndikuwonjezera moyo wa batri ndi mphamvu zosintha. Thupi limapangidwa kuchokera ku polypropylene wopangidwa kuti likhale lolimba. Zolumikizanazo zimapangidwa ndi phosphor bronze yokhala ndi faifi tambala. Mapaketi amagetsi ophatikizikawa amatha kuyikidwa kapena kutsekedwa pa bolodi komanso pakati pazigawo ndipo ndioyenera kugulitsa kapena mafakitale. Amagawidwa kuti ateteze madera oyendetsera mabatire osayenera.
Zipangizozi zimakhala ndi chivundikiro chosungika chomwe chimatsekedwa ndikulumikiza ndi zomangira zotetezera zina.
