UNDERCUTTING WITH EXCAVATORS AND BACKHOES
The DymaxRail Ballast Blaster Undercutter for pin grab quick couplers is an undercutter attachment that features advanced patented design and durability. A DymaxRail Ballast Blaster Undercutter efficiently removes fouled ballast rock and mud by cutting and pulling the material out from beneath the railway tracks. This attachment adapts to Railway Excavators and Backhoe Loaders equipped with a traditional pin-grab type coupler system and feature built-in rotation and tilt for positioning.
FASTER AND MORE EFFICIENT
Rail networks prefer using DymaxRail Ballast Blasters over 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.
BLASTER WEAR PLATES
Our patented Ballast Blaster Undercutter features bolt on indexable wear plates with full carbide protection that surrounds all sides of the cutter bar and includes a 2 year warranty.
BI-DIRECTIONAL CUTTING
A DymaxRail Ballast Blaster cuts and removes ballast faster with it’s innovative chain design. The Dymax Carbide Tooth (DCT) features two-sided protection allowing operators to cut in both directions.
