- Calbrandt's most versatile mover
- Ideal for applications that feature bi-directional movement, empty and full cars, up to 75,000 lbs of force and have space limitations
- Indexer or progressor configurations
- An indexer attaches to the axle of the railcar and completes its cycle of motion then detaches and retrieves to the next railcar
- A progressor maintains continuous movement through the use of two attachment points, one retrieving while the other is pushing
