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. We can prove that you 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. It exceeds the productivity and durability of every other 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.

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.

Hydraulic Requirements
| Hydraulic Circuit Basic Requirements | |
|---|---|
| Motor Circuit (All Models) | All Dymax Rail Ballast Blasters regardless of model require a high pressure, high flow circuit with case drain to operate the cutting chain drive motor. The chain drive requires bi-directional oil control for operating in forward or reverse directions. For models working with tilt rotator (TR) systems this is the only circuit required for operation. |
| Rotation Gear Circuit (not applicable on tilt rotator models) | All Dymax Rail DTR 360° undercutter systems require a secondary circuit with medium pressure lines. This system needs to be operated in both directions forward/reverse and must be setup with valve logic in the following configuration.
1. AB to T logic 2. Open center valve design. |
| Bar Tilt Circuit (not applicable on tilt rotator models) | Dymax Rail provides an electro-hydraulic diverter valve on every 360° model. A basic wiring kit is provided and requires a power cable to be routed to the stick from a switch in the cab. This system diverts oil flow from the rotate circuit to operate the bar tilt control. |
| Hydraulic Kits Available | Dymax Rail can offer a complete or partial hydraulic kit to operate the Dymax Ballast Blaster 360° undercutter with excavators and backhoe loaders. Each kit is tailored to the specific machine and series and a serial number is required at time of request. |
