It’s the most cost-effective way to safely spot railcars using equipment you already own — no need for a dedicated railcar mover.

Maximize ROI: Use existing machines to move railcars – no need for specialized vehicles.
Industry-Leading Knuckle Design: All models feature a pivoting car knuckle with top and bottom retainer plates for the most secure connection.
Tractor Compatibility: Rear-mounted models fit Category 2, 3, and 4 hitches. Front-mount versions available for select tractor models.
Wheel Loader Versatility: Front-mounted models can be configured with coupler hooks for most major brands. Rear-mounted solutions are engineered to fit your specific loader.

RAILCAR AIR BRAKE CONTROL SYSTEM (Optional)

CONTROL RAILCARS WITH CONFIDENCE — POWERED BY YOUR MACHINE.

The Dymax Railcar Air Brake Control System brings high-performance braking to your loader for safe, efficient railcar movement. Powered by your machine’s hydraulics, it uses a heavy duty 2-stage screw compressor—no engine required. Operators control car brakes and air latches from the cab. The system mounts flexibly on the coupler, frame, or rear deck to suit your setup.
