E02F3/30 - 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

Sub-classes:

E02F3/301 » {with more than two arms (boom included), e.g. two-part boom with additional dipper-arm} 58
E02F3/302 » {with an additional link} 23
E02F3/303 » {with the dipper-arm or boom rotatable about its longitudinal axis} 7
E02F3/304 » {with the dipper-arm slidably mounted on the boom } 76
E02F3/305 » {with the dipper-arm slidably mounted on the boom and the boom slidably mounted on the frame} 4
E02F3/306 » {with telescopic dipper-arm or boom} 21
E02F3/307 » {the boom and the dipper-arm being connected so as to permit relative movement in more than one plane} 11
E02F3/308 » {working outwardly} 173
E02F3/32 » working downwardly and towards the machine, e.g. with backhoes 844
