## Abstract

The present invention relates to a caterpillar track (2), in particular a rubber caterpillar track (2), with a track body (20) and with at least one outer profiling element (22), preferably with a plurality of outer profiling elements (22), which are directed outwardly away from the track body (20). The caterpillar track (2) is characterized in that the outer profiling element (22) has an outwardly directed grouser body (23) and a grouser root (24), which connects the grouser body (23) to the track body (20), wherein the outer profiling element (22) has, at least in some sections, a marking (26, 27, 28) which can make the boundary (25) between the grouser body (23) and the grouser root (24) visually and/or haptically identifiable.

## Claims

### Claim at position 1

-10. (canceled)

### Claim 11

A rubber caterpillar track comprising a track body having a plurality of outer profiling elements which are directed outwardly away from the track body, wherein each of the plurality of outer profiling elements comprises an outwardly directed grouser body and a grouser root, and wherein the grouser root connects the grouser body to the track body;
wherein the outer profiling element comprises a marking which makes a boundary between the grouser body and the grouser root visually or visually and haptically identifiable; and,
wherein the grouser body comprises a material of a first color and the grouser root comprises a material of a second color, and wherein the first color and the second color are different from one another.

### Claim 12 (depends on 11)

The rubber caterpillar track as claimed in claim 11, wherein the outer profiling element has, at the boundary between the grouser body and the grouser root one or more of a depression and an elevation.

### Claim 13 (depends on 11)

The rubber caterpillar track as claimed in claim 11, wherein the grouser body and the grouser root consist of different materials.

### Claim 14 (depends on 13)

The rubber caterpillar track as claimed in claim 13, wherein the grouser body consists of a material which provides one or more of higher abrasion-resistance, higher grip, and damping with respect to the underlying surface, in comparison to the material of the grouser root.

### Claim 15 (depends on 13)

The rubber caterpillar track as claimed in claim 13, wherein the grouser root consists of a material which provides one or more of less heat build-up, greater dynamic strength, and better bonding to the material of the track body, in comparison to the material of the grouser body.

### Claim 16 (depends on 11)

The rubber caterpillar track as claimed in claim 11, wherein the material of the grouser body comprises an elastomeric material, and wherein the material of the grouser root comprises an elastomeric material.

### Claim 17 (depends on 11)

The rubber caterpillar track as claimed in claim 11 further comprising a plurality of tension members embedded in the track body.

### Claim 18

A rubber caterpillar track comprising a track body having a plurality of outer profiling elements which are directed outwardly away from the track body, wherein each of the plurality of outer profiling elements comprises an outwardly directed grouser body and a grouser root, and wherein the grouser root connects the grouser body to the track body;
wherein the outer profiling element comprises a marking which makes a boundary between the grouser body and the grouser root visually or visually and haptically identifiable; and,
wherein a colored material that differs in color from the material of the grouser body and from the material of the grouser root is arranged as the marking at the boundary between the grouser body and the grouser root.

### Claim 19 (depends on 18)

The rubber caterpillar track as claimed in claim 18, wherein the outer profiling element has, at the boundary between the grouser body and the grouser root one or more of a depression and an elevation.

### Claim 20 (depends on 18)

The rubber caterpillar track as claimed in claim 18, wherein the grouser body and the grouser root consist of different materials.

### Claim 21 (depends on 20)

The rubber caterpillar track as claimed in claim 20, wherein the grouser body consists of a material which provides one or more of higher abrasion-resistance, higher grip, and damping with respect to the underlying surface, in comparison to the material of the grouser root.

### Claim 22 (depends on 20)

The rubber caterpillar track as claimed in claim 20, wherein the grouser root consists of a material which provides one or more of less heat build-up, greater dynamic strength, and better bonding to the material of the track body, in comparison to the material of the grouser body.

### Claim 23 (depends on 18)

The rubber caterpillar track as claimed in claim 18, wherein the material of the grouser body comprises an elastomeric material, and wherein the material of the grouser root comprises an elastomeric material.

### Claim 24 (depends on 18)

The rubber caterpillar track as claimed in claim 18 further comprising a plurality of tension members embedded in the track body.

### Claim 25

A rubber caterpillar track comprising a track body having a plurality of outer profiling elements which are directed outwardly away from the track body, wherein each of the plurality of outer profiling elements comprises an outwardly directed grouser body and a grouser root, and wherein the grouser root connects the grouser body to the track body;
wherein the outer profiling element comprises a marking which makes a boundary between the grouser body and the grouser root visually or visually and haptically identifiable; and,
wherein the outer profiling element has a colored marking at the boundary between the grouser body (23) and the grouser root, and wherein the colored marking differs in color from the material of the grouser body and from the material of the grouser root, and wherein the colored marking is disposed upon the outer profiling element outside surface.

### Claim 26 (depends on 25)

The rubber caterpillar track as claimed in claim 25, wherein the outer profiling element has, at the boundary between the grouser body and the grouser root one or more of a depression and an elevation.

### Claim 27 (depends on 25)

The rubber caterpillar track as claimed in claim 25, wherein the grouser body and the grouser root consist of different materials.

### Claim 28 (depends on 27)

The rubber caterpillar track as claimed in claim 27, wherein the grouser body consists of a material which provides one or more of higher abrasion-resistance, higher grip, and damping with respect to the underlying surface, in comparison to the material of the grouser root.

### Claim 29 (depends on 27)

The rubber caterpillar track as claimed in claim 27, wherein the grouser root consists of a material which provides one or more of less heat build-up, greater dynamic strength, and better bonding to the material of the track body, in comparison to the material of the grouser body.
