Ballast Blaster Undercutter

BALLAST BLASTER EXCAVATOR AND BACKHOE UNDERCUTTERS:

Dymax Rail Ballast Blaster Undercutters outperform all other methods for ballast removal. Some rail networks prefer it to conventional on-track ballast cleaners, as they are more efficient and easier to get on and off track, especially congested networks with severe time restraints. Our Ballast Blaster Undercutter will more than double productivity and cut operating costs by more than half! Get the work done within limited track time. The Ballast Blaster is the safest to operate and easiest to maintain undercutter on the market and it exceeds the productivity and durability of every brand of undercutter.

World’s First Undercutter with Integrated 360° Rotation System:

The Dymax Rail Ballast Blaster is the world’s first undercutter with full 360° continuous rotation. The added flexibility gives operators the ability to work from either side of the tracks. It also greatly improves management of spoil piles, allowing operators flexibility and maximum cutting speed and performance.

Dymax Rail Ballast Blasters are also available to fit tilt-rotator coupler systems.

NXG-360 Ballast Blaster Undercutter:

Full rotation design for fitting pin grab couplers on excavator or backhoe loader. Full manipulation control allowing machines to cut from any position on either side of the railroad tracks. Easy service interface with the latest undercutting technology. Available in 4 cutting lengths.

NXG-TRQ Ballast Blaster Undercutter:

For fitting tiltrotator quick coupler systems similar to Engcon, Rototilt, Steelwrist, SMP among others. Easy service interface available in 5 cutting lengths.

NXG-180 Ballast Blaster Undercutter:

Powerful rotator system delivers up to 180 degrees of rotation using hydraulic cylinder power which makes the NXG-180 ideal for larger machinery. Easy service interface with the latest undercutting technology. Available in 2 cutting lengths.

Dymax Rail’s Spoilmaster:

The Spoilmaster™ can be added to the Dymax Rail 10 foot, 12 foot, and 15 foot Ballast Blasters. Spoilmaster™ requires an additional hydraulic circuit with case drain, which requires minimal oil flow and pressure. Spoilmaster™ does not require high cost adaptive hydraulic power units to be added to the machine, and works with standard excavator hydraulics that can easily be removed from the Ballast Blaster when not required.

Spoilmaster™ is smarter, more efficient, and delivers excellent performance. It’s spoil management simplified. Contact Dymax Rail for hydraulic information to see if Spoilmaster™ will work on your specific machine size.
