Caterpillar backhoe equipped with Dymax LoPro Rail Rider hi-rail system operating on CN railroad track

SUPERIOR HI-RAIL FOR CATERPILLAR BACKHOES

DYMAX LOPRO RAIL RIDER

BUILT FOR CAT 416, 420 & 430 IT MODELS

The LoPro Premium Rail Rider is designed for customers who want better on-rail performance without the hassle of complex installation.

No welding required – this system uses a 5th-wheel hitch-style connection that mounts directly to a rear pin for faster install, easier removal, and a cleaner machine.

Larger diameter rail wheels deliver smoother tracking through curves and elevation changes, while integrated rail sweeps and a built-in park brake add control and safety where it matters.
