Partial cut machine for roadway opening

摘要

On an undercarriage is mounted the machine frame, on which is swivelably mounted a length-adjustable jib (8) with a cutter head (9) at front end. At the head end is mounted a loading bucket (5), inclined to the roadway floor, linked to at least one conveyor for debris removal. The cutter head is reciprocated by the jib between a front end position, protruding above the bucket, and a rear position with the jib lowered, in which it does not protrude above the bucket, or only partly. Pref. the jib consists of telescopic section.
