Abstract
A crib ballast clearing machine comprises a machine frame supported on undercarriages adapted to support the machine frame on a track comprised of rails fastened to ties defining cribs therebetween, and a ballast scarifying device comprising a revolvable endless excavating chain vertically adjustably mounted on the machine frame for removing ballast from a respective one of the cribs between the rails, a drive for revolving the endless excavating chain, and a displacement drive for vertically adjusting the endless excavating chain. The endless excavating chain has a lowermost ballast receiving part being immersible in ballast in the crib between the rails upon vertical adjustment of the endless excavating chain.
Claims4
A machine comprising
- (a) a machine frame supported on undercarriages adapted to support the machine frame on a track comprised of rails fastened to ties defining cribs therebetween, and
- (b) a ballast scarifying device comprising
- (1) a revolvable endless excavating chain vertically adjustably mounted on the machine frame for removing ballast from a respective one of the cribs between the rails,
- (2) a drive for revolving the endless excavating chain, and
- (3) a displacement drive for vertically adjusting the endless excavating chain,
- (4) the endless excavating chain having a lowermost ballast receiving part being immersible in ballast in the crib between the rails upon vertical adjustment of the endless excavating chain, points of contact between the track rails and wheels on the undercarriages defining a running plane extending in a longitudinal direction along the track, and the endless excavating chain being arranged to revolve and to be vertically adjusted in a plane extending transversely to the longitudinal direction and at an acute angle to the running plane.
