Kumiswa kwakazvimirira kwemaoko maviri kwenguva refu
Kumiswa kwemaoko maviri kwakazvimiririra kwenguva refu kunoreva kusungirirwa uko vhiri rega rega repadivi rakasungirirwa nefuremu kuburikidza nemaoko maviri akarebesa uye vhiri rinogona kungosvetukira mudenga remota chete. Rinoumbwa nemaoko maviri akarebesa, zvinhu zvinonamira, zvinobata mabara uye mabhara anochinjika. Mugumo mumwe weruoko wakasungirirwa negumbo, rimwe pamusoro perimwe zvakare, uye rimwe mugumo wakabatana zvakasimba kune rimwe ruoko. Chikamu chemukati cheshaft yeruoko rwakarebesa chine gomba re rectangular rekuisa chitubu chebhara rakaita semashizha. Mugumo wemukati wechitubu chebhara rakaita semashizha wakasungirirwa pakati pedanda uchishandisa masikuruu. Masipiringi maviri ebhara akasungirirwa mubhara rawo re tubular.
