High Rail Excavator
First Claim
Patent Images
1. An excavator, comprising:
- a pair of tracks mounted in opposed spaced relation, each one of the pair of tracks having an inner peripheral edge, the inner peripheral edges spaced apart a first distance;
a high rail mechanism interposed between the inner peripheral edges and having a pair of wheels spaced apart by a second distance; and
wherein the first distance is greater than the second distance, such that the pair of wheels are interposed between the tracks.

Abstract
A high rail excavator is provided. The high rail excavator includes at least one high rail mechanism to elevate the high rail excavator relative to the rails of a railroad track. The high rail mechanism is disposed within an envelope of the tracks, thereby increasing the maneuverability and safety of the high rail excavator. The high rail mechanism includes a power control arrangement that integrates with a power supply of the excavator so that an additional power supply dedicated to the high rail mechanism is not required.

7. A high rail mechanism, comprising:
-
an upper mount; a lower mount; a pair of wheels carried by the lower mount; a linkage connected between the upper and lower mounts; an actuator operably connected to the linkage, the actuator operable to move the lower mount and the wheels relative to the upper mount and in a first direction away from the upper mount, and move the lower mount and the wheels relative to the upper mount in a second direction toward the upper mount. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method of affixing a high rail mechanism to an excavator, the method comprising the steps of:
-
adjusting a first distance between inner peripheral edges of a pair of tracks in opposed spaced relation to a second distance greater than the first distance; and mounting the high rail mechanism having an overall width less than the second distance to the excavator between the inner peripheral edges. - View Dependent Claims (15, 16, 17, 18)
