Dymax Rail Rider X2 | Hi-Rail Your Track Excavator (6T-36T)

YOU DON’T NEED A HI RAIL EXCAVATOR. YOU NEED HI-RAIL ACCESS.

The Dymax Rail Rider X2 converts new or existing excavators for rail work — without permanently modifying the machine.

Install it in days. Remove it when the job is done.

How the X2 Attaches — Without Modifying Your Machine

  • Wedge-locking adapters (patent-pending) create a secure connection between the X2 undercarriage and the machine.
  • The excavator sits fully supported on the X2 structure—not cantilevered off the ends of the frame—for improved stability, safety, and machine support.
  • Modular front and rear railgear assemblies remove for off-track work.
  • Pre-hosed hi-rail system designed for simplified dealer or in-shop installation.

YOUR EXCAVATOR STAYS SELLABLE

A permanently modified rail excavator can be hard to resell. The only person who wants it is your competition.

You invested nearly 7-figures in that machine. The next owner didn’t. Now they’re bidding against you.

Are you sick of funding your own competition?

The Dymax Rail Rider X2 is different.

Keep the railgear. Sell the unmodified excavator. Reinvest the savings.
