Kuyika ma rabara opangidwa ndi excavator ndi njira yosavuta, yogwirizana ndi mitundu yambiri yamakono ya excavator.mapepala oyendetsera njanjiAmapangidwa ndi mapatani a bolt, zomwe zimathandiza kuti zisinthidwe mwachangu popanda kufunikira kusintha kwakukulu. Makina ambiri ofukula ma rabara amakhala ndi njira zolumikizirana kapena mabowo obooledwa kale kuti azigwira bwino ntchito, zomwe zimachepetsa nthawi yogwira ntchito panthawi yokonza. Poyerekeza ndi ma rabara ofukula zitsulo, mitundu ya rabara ndi yopepuka, zomwe zimapangitsa kuti kugwiritsa ntchito ndi kuyika zikhale zosavuta kwa akatswiri. Kuphatikiza apo, kusinthasintha kwawo kumatsimikizira kuti zikugwirizana bwino, kuchepetsa chiopsezo chotha kusweka panthawi yogwira ntchito. Kaya kusintha ma rabara akale kapena kusintha kuchokera ku njanji zachitsulo, ma rabara ofukula opangidwa ndi rabara amapereka njira yoyikira yopanda mavuto.

Mapepala a rabara ofukula zinthu zakaleAmapangidwa kuti azigwira ntchito bwino kwambiri m'nyengo zosiyanasiyana, kuyambira kutentha kozizira mpaka kutentha kwambiri. Mosiyana ndi ma track pad achitsulo, omwe amatha kufooka m'nyengo yozizira kapena kuterera akanyowa, ma track pad a rabara amakhala ndi mphamvu yogwira ntchito komanso kusinthasintha nthawi zonse. Ma rabara apamwamba omwe amagwiritsidwa ntchito mu ma track pad a excavator amalimbana ndi ming'alu m'malo omwe ali pansi pa zero pomwe amaletsa kutentha kwambiri m'malo otentha kwambiri. Izi zimapangitsa kuti akhale abwino kwambiri kugwiritsidwa ntchito chaka chonse m'madera omwe nyengo imasintha kwambiri. Kuphatikiza apo, ma track pad amapereka mphamvu zabwino kwambiri zotayira matope, kuteteza dongo ndi zinyalala zomwe zingasokoneze kuyenda. Kwa makontrakitala ogwira ntchito m'malo osiyanasiyana okhala ndi nthaka yosiyanasiyana, ma track pad awa amapereka ntchito yodalirika mosasamala kanthu za mavuto a nyengo.
