E02F3/304 - CPC Classification

Classification description:

Dredgers; Soil-shifting machines mechanically-driven with digging tools mounted on a dipper- or bucket-arm, i.e. there is either one arm or a pair of arms , e.g. dippers, buckets with a dipper-arm pivoted on a cantilever beam, i.e. boom with the dipper-arm slidably mounted on the boom
