A shoe (10) for a crawler track has two roller paths (16, 17) thereon, upon which a dual rim roller travels in use. The roller paths (16, 17) are aligned with leading and trailing lugs (11, 12) respectively, of the shoe 10. Drive lugs (18, 19) are provided on the outside of the roller paths (16, 17)
A shoe (10) for a crawler track has two roller paths (16, 17) thereon, upon which a dual rim roller travels in use. The roller paths (16, 17) are aligned with leading and trailing lugs (11, 12) respectively, of the shoe 10. Drive lugs (18, 19) are provided on the outside of the roller paths (16, 17). In use, the drive lugs (18, 19) are engaged by sprocket teeth to drive the crawler track. The drive lugs (18, 19) stand proud of the roller paths (16, 17), but may also be recessed below the roller paths.

The invention claimed is: 1. A crawler track shoe comprising a body having a pair of parallel roller paths on an upper surface of the body upon which respective rollers travel in use, a pair of drive lugs operatively engaged by sprocket teeth, each drive lug being located adjacent a respective roll
The invention claimed is: 1. A crawler track shoe comprising a body having a pair of parallel roller paths on an upper surface of the body upon which respective rollers travel in use, a pair of drive lugs operatively engaged by sprocket teeth, each drive lug being located adjacent a respective roller path and on a side of the respective roller path opposite to the other roller path, a leading connection lug located on one end of the body for articulated connection to a shoe adjacent said one end of the body, a trailing connection lug located on the opposite end of the body for articulated connection to another shoe adjacent said opposite end of the body, each roller path being aligned with, and extending along the top of, a respective connection lug and being of similar width thereto, wherein at each end of the body, the end of one roller path is longitudinally offset relative to the end of the other roller path in the direction of the roller paths, such that the transition from one shoe to an adjacent shoe along one roller path is longitudinally offset in the direction of the roller paths relative to the transition between the same shoes along the other roller path. 2. A shoe as claimed in claim 1, wherein each of the drive lugs has a sprocket tooth contact portion which is recessed below the roller paths. 3. A shoe as claimed in claim 2, wherein each of the drive lugs also has a sprocket tooth contact portion extending above the roller paths. 4. A crawler track shoe as claimed in claim 1 wherein each drive lug has a sprocket tooth contact portion extending above and below the roller paths. 5. A crawler track comprising a plurality of shoes linked together to form an endless track, each shoe comprising a body having a pair of parallel roller paths on an upper surface of the body upon which respective rollers travel in use, a pair of drive lugs operatively engaged by sprocket teeth, each drive lug being located adjacent a respective roller path and on a side of the respective roller path opposite to the other roller path, a leading connection lug located on one end of the body for articulated connection to a shoe adjacent said one end of the body, a trailing connection lug located on the opposite end of the body for articulated connection to another shoe adjacent said opposite end of the body, each roller path being aligned with, and extending along the top of, a respective connection lug and being of similar width thereto, wherein at each end of the body, the end of one roller path is longitudinally offset relative to the end of the other roller path in the direction of the roller paths, such that the transition from one shoe to an adjacent shoe in the track along one roller path is longitudinally offset in the direction of the roller paths relative to the transition between the same shoes along the other roller path. 6. A crawler track shoe as claimed in claim 5 wherein each drive lug has a sprocket tooth contact portion extending above and below the roller paths.
