Makina ophatikizika a bidirectional flat compactor amagwiritsidwa ntchito kwambiri pophatikizira, makamaka pophatikizira munjira zopapatiza, ndipo atha kugwiritsidwa ntchito pophatikizira maziko a uinjiniya ndi phula la phula. Ndipo ili ndi makhalidwe ena, omwe ndi:
(1) Yosavuta kuyambitsa komanso ntchito yosalala;
(2) Chipinda chapansi cha compactor chathyathyathya chimapangidwa ndi chitsulo cha manganese alloy kapena ductile iron material, yomwe imakhala ndi kukana kwabwino;
(3) Pamwamba pake adapoperapo pulasitiki, yokhala ndi gloss ya magnesium, ndipo imatha kuteteza dzimbiri ndi dzimbiri.
Mfundo yogwirira ntchito ya bidirectional flat compactor ndi motere: injini mu compactor lathyathyathya imayendetsa eccentric kuti ipangitse kugwedezeka kudzera pa clutch ndi pulley, ndipo mbale yapansi ndi eccentric zimakhazikika palimodzi. Kuti musinthe momwe kugwedezeka kumayendera, zitha kutheka potembenuza chipika cha eccentric. Kuphatikiza apo, kuti mukwaniritse kugwedezeka kwamtsogolo, kugwedezeka m'malo, ndi kugwedezeka kumbuyo.
