Abstract
An apparatus for cribbing and anchor attachment on rails of a railroad track, including a frame movable along the track, at least one dual function workhead mounted to the frame that is moveable into and out of operational position relative to the track, an anchor applicator tool pivotably mounted to each workhead, and a cribber tool mounted to each workhead and adjacent the anchor applicator tool. Each anchor applicator tool and cribber tool is movable under operator control relative to the workhead from a retracted position to a work position.
Claims20
An apparatus for cribbing and anchor attachment on rails of a railroad track, comprising:
- a frame movable along the track;
- at least one dual function workhead mounted to said frame that is moveable into and out of operational position relative to the track;
- an anchor applicator tool pivotably mounted to each said workhead;
- a cribber tool mounted to each said workhead and adjacent said anchor applicator tool;
- each said anchor applicator tool and said cribber tool being movable under operator control relative to said workhead from a retracted to a work position;
- and
- said anchor applicator tool is pivotable relative to said workhead, said cribber tool is independently pivotable relative to said workhead, and said apparatus is constructed and arranged so that in operation, said cribber tool is moved in an arc toward a designated rail of the track to clear a path through the ballast, and is then retracted, and said anchor applicator tool then is supplied with an anchor and is pivotably moved toward the rail to apply the anchor to the rail.

A method for applying rail anchors to a railroad track, comprising:
- moving a rail cribber and anchor applicator machine along the track to a designated location, said machine having at least one anchor applicator and cribber workhead;
- activating at least one rail clamp on said applicator machine for holding the machine tightly to the track;
- lowering the workhead to an intermediate position;
- extending a cribber tool on said workhead from a retracted position to a work position, in which an arm having a ballast pushing surface at a free end is placed adjacent a top surface of the ballast, near a top surface of adjacent rail ties;
- pivoting said workhead to create a cribbing action in the ballast;
- retracting said cribber tool;
- extending an anchor applicator tool on said workhead from a retracted position to a work position in which an anchor is supplied to a free end of said anchor applicator tool;
- pivoting said workhead to apply the anchor onto a foot of a target rail of the track;
- retracting said anchor applicator tool;
- and
- raising said workhead from said intermediate position to a travel position.

- moving a rail cribber and anchor applicator machine along the track to a designated location, the machine having a workhead with at least one anchor applicator tool and at least one cribber tool;
- activating at least one rail clamp on the applicator apparatus for holding the machine tightly to the track;
- lowering the workhead to an intermediate position;
- extending a cribber tool on the workhead from a retracted position to a work position, in which an arm having a ballast pushing surface at a free end is placed adjacent a top surface of the ballast, near a top surface of adjacent rail ties;
- extending an anchor applicator tool on the workhead from a retracted position to a work position;
- supplying an anchor to a free end of said anchor applicator tool;
- pivoting the workhead to create a cribbing action in the ballast, and pivoting the workhead to apply the anchor onto a foot of a target rail of the track;
- retracting the anchor applicator tool;
- retracting the cribber tool so that a cribber plate is pivoted out of engagement with the anchor;
- and
- raising the workhead from the intermediate position to a travel position.
