Dulmarka guud ee xarkaha wareega guga

Barxadda wareega ee birta ah ayaa ku habboon codsiyo badan oo kala duwan oo ah noocyo kala duwan oo ay ka mid yihiin ilo fidsan, xargaha, xargaha takhtarka, gogosha, goynta, mindida, saxarada, weelka, qalabka masinonry, aaladaha masinon. Marka kuleylka lagu daaweeyo heerkulka EN42, oo ay kujirto heerka kuleylka, qaboojinta iyo jiirka, iwm way kala duwanaan doontaa sababta oo ah qaabka ay ka mid yihiin qaabka iyo cabirka qayb kasta. Tixgelinno kale inta lagu gudajiro nidaamka daaweynta kuleylka waxaa ka mid ah nooca foornada, oo ka daadanaya dhexdhexaad, iyo tas-hiilaadka wareejinta shaqada. Fadlan kala tasho bixiyaha daaweynta kuleylka si aad u hesho hagis buuxa oo ku saabsan daaweynta kuleylka guga.
