1. Zodzikongoletsera ndi chitukuko chapamwamba: ndi chitukuko chofulumira chamakono, zida zamakina a njerwa zimakhalanso zatsopano komanso kusintha tsiku lililonse. Makina amtundu wa njerwa samangotulutsa zotulutsa komanso zodzichitira okha, komanso zoperewera muukadaulo. Ubwino ndi maonekedwe a njerwa zopangidwa si zabwino kwambiri. Tsopano kudzera mukugwiritsa ntchito ukadaulo wapamwamba wa hydraulic, zida zamakina anjerwa zambiri zimakhala zapamwamba kwambiri, Kupanga makina opangira makina kwalowetsa mphamvu zopanda malire pakupanga makina a njerwa. Tekinoloje ndiye maziko a chitukuko cha zida zamakina a njerwa. Matani amakono a zipangizo zamakina a njerwa apangidwa kuchokera ku ang'onoang'ono mpaka akuluakulu, ndipo luso lamakono likupita patsogolo kwambiri.

2. Multifunction: zida zina zamakina a njerwa zimatha kupanga mtundu umodzi wazinthu. Chifukwa cha kufunikira kwa zinthu zosiyanasiyana komanso kukula kosalekeza kwa msika, kufunikira kwa njerwa kwa anthu kukukulirakulira. Ngati makina opangira njerwa amatha kupanga mtundu umodzi wazinthu, amawonjezera mtengo wogulira zida ngati akufuna kupanga zinthu zambiri. Choncho, makina osindikizira a njerwa amakono akukula motsatira njira zambiri, pogwiritsa ntchito zipangizo zamakono kuti azindikire ntchito zambiri zamakina amodzi, zomwe zimakwaniritsa zofunikira za msika ndi ogwiritsa ntchito.

3. Kupulumutsa mphamvu, kubwezeretsa zinyalala ndi kuteteza chilengedwe: dongo linkagwiritsidwa ntchito ngati zopangira njerwa zambiri m'mbuyomu, ndipo chitukuko cha nthawi yaitali chidzabweretsa zotsatira zoopsa za kuwonongeka kwa nthaka. Ndi chitukuko chachangu zachuma, ochulukirachulukira mphamvu chomera ntchentche phulusa, zinyalala mafakitale, zinyalala zomangamanga, etc., mbadwo watsopano wa zida atolankhani njerwa akhoza mogwira ntchito zinyalala zinthu kupanga zinthu zatsopano chitetezo champanda khoma, kuzindikira kuteteza mphamvu ndi zinyalala yobwezeretsanso zinyalala, kusintha zongowonjezwdwa magwiritsidwe zinyalala, ndi kukhala kulinga ku chitsogozo cha chitetezo chilengedwe.
