Abstract
A machine for removing an old track and for simultaneously laying a new track on a ballast bed, which comprises a first tie transport apparatus for receiving the old ties, and a second tie transport apparatus for delivering new ties and laying the new ties. A lifting device may be selectively placed in an operating position on the first or the second tie transport apparatus for insertion between the ballast bed and an old tie for engaging the old tie and lifting it off the ballast bed. This may be done by selectively coupling the lifting device to a respective tie transport apparatus, or by driving the lifting device on each tie transport apparatus between operative and inoperative positions.
Claims5
A machine for removing an old track comprised of old rails and old ties from a ballast bed, and for simultaneously laying a new track comprised of new rails and new ties, which comprises
- (a) a first tie transport apparatus for receiving the old ties,
- (b) a second tie transport apparatus for delivering the new ties and laying the new ties,
- (c) a lifting device selectively placeable in an operating position on the first or second tie transport apparatus for insertion between the ballast bed and an old tie for engaging the old tie and lifting it off the ballast bed, and
- (d) a coupling device on each tie transport apparatus for detachably affixing the lifting device to the selected tie transport apparatus.
A method for removing an old track comprised of old rails and old ties from a ballast bed, and for simultaneously laying a new track comprised of new rails and new ties on the ballast bed, with a machine moving in an operating direction, which comprises
- (a) engaging the old ties with a first tie transport apparatus including a tie lifting device for lifting the old ties off the ballast bed and removing the lifted old ties with a first tie conveying device moving in a conveying direction,
- (b) simultaneously delivering the new ties to a second tie transport apparatus with a second tie conveying device moving in a conveying direction and laying the new ties with the second tie transport apparatus, and
- (c) enabling the machine to reverse the operating direction by
- (1) detaching the tie lifting device from the first transport apparatus and connecting it with the second tie transport apparatus, and
- (2) reversing the conveying directions of the first and second tie conveying devices.
A machine for removing an old track comprised of old rails and old ties from a ballast bed, and for simultaneously laying a new track comprised of new rails and new ties, which comprises
- (a) a first tie transport apparatus for receiving the old ties,
- (b) a second tie transport apparatus for delivering the new ties and laying the new ties,
- (c) a lifting device on each tie transport apparatus for insertion between the ballast bed and an old tie for engaging the old tie and lifting it off the ballast bed, and
- (d) a drive for selectively moving each lifting device between an operating position wherein it engages the old tie and an inoperative position.
