Cat 287B Tracks Specifications
Cat MTL machines are great for various types of terrain and multi-purpose use. The great thing about these track loaders is their ability to be so versatile on slopes and hills. A lot of this has to do with a balance of weight being distributed thorough the machine. Other track loaders have a huge amount of weight in the back of the machine making it difficult to maneuver sideways on hills as well as getting over the top of a slope upright. The other half of the versatility is the track itself. Our Posi-Track style tracks are all made with either tensile-like steel cords running throughout the rubber or an aramid-cord system performing the same concept of strength. These cords are actually supporting the structure and integrity of the track allowing to track the conform to the terrain itself. This is going to give an immense amount of traction because of the flexibility to the track and allow the machine to work and go through environments that other machines will not be able to maneuver through.
All of our Cat MTL style tracks are made with 100% new (non-recycled) rubber which eliminates any bonding issues from casts making the tracks last longer without the extensive cracking. Typically your standard track loader track on a steel undercarriage system will run about 1000 hours yet the Cat MTL type tracks have the potential to see 2000 if maintained and kept in the proper conditions. The way Cat MTL 287B models are set up on average, track life can be 1500 to 2000 hours. That being said, some Cat 287B tracks have seen over 4000 hours.
As you can see in the picture to the left, the tensile-like polyester mesh and the aramid-cords here are strategically placed throughout the track rubber. This will allow for the flexibility and conformability to terrain when the track meets the ground. It is also forcing the track to be bound together, not letting it stretch to help eliminate derailing. This track was in service for several hundred hours before we cut a sample section and you can see how perfectly aligned the cords are even after extensive time in the field.
The 18 inch wide tracks that run on the on the Cat 287b series have a rows of drive lugs down the center of the track that provides even torque distribution while keeping the track aligned. The drive lugs fall into the bogey drive wheel to drive the machine while the outside guide lugs simply hug the rollers and the undercarriage to keep the track straight.
