Abstract
In a method for efficiently removing a great number of damaged rail sections, after a first separating cut, the severed free rail ends are gripped by a rail pulling device connecting the rail ends to one another, and are pulled towards one another. The pulling force required for the pulling-together as well a current rail temperature are registered for calculation of that length of a replacement rail which is required for producing a desired rail tension. A second separating cut is carried out—with corresponding path measurement—spaced at a distance from the first separating cut as calculated on the basis of the selected length of the replacement rail.
Claims8
A machine for preparation of rail weld, comprising:
- a machine frame and on-track undercarriages supporting said machine frame on a track;
- a rail storage facility for storing a plurality of replacement rails;
- a crane jib assembly with drives for vertically and rotatably adjusting a crane jib for gripping and unloading a replacement rail;
- a vertically adjustable rail cutting saw adjustably mounted on a saw guide extending in a longitudinal direction of said machine frame;
- a rail pulling device mounted on said machine frame and having two mutually spaced-apart pairs of rail clamps configured for gripping and pulling together two rail ends;
- and
- a pair of lifting rams mounted to said machine frame in immediately proximity to a respective on-track undercarriage, said lifting rams being configured to be lowered for placement upon a track, and for lifting the proximate said on-track undercarriage from the track.
