Mupi wemidziyo yekuvakisa yezvigadziriso zvemichina yekuvaka kwemakore makumi maviri nemashanu.
Mamini ekuchera anowanzo kufarirwa nenzvimbo dzebasa dzine nzvimbo dzakasimba, dzinokwanisa kuenda uko michina mikuru isingakwanise. Mamini anochera akanakira basa kuseri kwemba, mukati mezvivakwa uye kutenderedza fenzi yekuchera, kusimudza uye kuchenesa-kumusoro.
I DIGGER
Mabhakiti akajairwa anochera pasi nezvinangwa zvakawanda, uye iwe unofanirwa kuona kuti ndeapi maficha anodiwa zvichienderana nebasa. Mabhaketi ebasa rekuchera zvakazara anouya muzvikamu zvakawanda, uye kugona kunoenderana nekukura kwebhaketi uye chimiro, pamwe nerudzi rwevhu repanzvimbo yako yebasa.
II RIPPER
Usarege kutonhora kwemamiriro ekunze kana matombo ane matombo asingatarisirwe achinonotsa kushanda. Munzvimbo dzine tsvina yakaoma, yakakora kana chando, maburi anocheka nepakati pemamiriro evhu akaoma kuti asunungure ivhu nekuvandudza goho.
III Yakagadzirirwa kuchera makomba emhando nehukuru hwese, augers dzinogona zvakare kubereka kuburikidza nemhando dzakasiyana dzevhu. Kubva pakuisa mapango efenzi kana mapango ekuvakisa kusvika pakudyara makwenzi, auger inobvisa ivhu zvine mutsindo kune zvaunofunga. Muvhu rakakora, sarudza auger ine kumhanya kwakanyanya uye torque kudzivirira kudzikama.
Hazvina mhosva kuti ndechipi chinonamatira chaunosarudza, kunaka uye dhizaini zvinhu zvakakosha pakusarudza michina. Kuti ugare nemaawa akawanda ekushandiswa munzvimbo dzakaoma, yakakwirira-simba, simbi yakanyoro ichasimuka kuti isakara uye kubvaruka. Pamusoro pezvo, tsigiro kubva kune akavimbika mutengesi inorerutsa kunetseka.
