DRIVE TYPE: HYDROSTATIC RAIL AXLE
FIRST OF ITS KIND
Get on the rails fast with the Dymax Rail Rider H-W1. This hydrostatically driven hi-rail attachment quickly adapts to wheel-type hydraulic excavators. There’s no cutting, welding or modifying of any kind, unless you want us to like the other guys do.
- Elevated stability – Heavy duty design provides a lower center of gravity when driving on rail, helping to stabilize the excavator during operations.
- Do more work over side – Available with rail clamps and optional stabilizer systems.
- Enhanced safety features – This auto-lock railgear engages during road and rail applications to prevent hydraulic drifting. DymaxRail’s control group also includes slew and boom lockouts.
- Better control – Our innovative hydraulic drive system provides full hydrostatic feel and control, so when operators need to slow down they can.
- Better braking – Equipped with fail-safe hydraulic disc brakes that always set when stopped.
- Self-contained directional lighting systems – Red and white directional lights change automatically. No plugs connect to your excavator.
- 100% detachable – The Dymax Rail Rider H-W1 attaches to your undercarriage through its patent-pending interface, making it highly efficient.
- Advanced stability features for 3rd rail networks – Built-in hydraulic stabilizers provide enhanced stability without worries of hitting the 3rd rail.
Hydrostatic drive with innovative circuit technology that eliminates motor cavitation problems or we’ll replace it for free.
Heavy duty 4 bar linkage for long lasting durability
DymaxRail’s specialized stabilizer technology and rail clamps offer significant safety advantages over traditional hi-rail setups.
Non-weld interface features high strength support beams and slack adjuster.
Replaceable 20 inch rail wheels for smooth and stable ride.
