Tamping AST 4

Tamping work at tracks, switches and crane ways is efficiently executed with the “Attachment Tamping Unit AST4” from Windhoff Gleisbautechnik GmbH. The attachment features two working units with a total of 4 pokers which simultaneously dig into the crib ballast.
A rotating cylinder permits the alignment of the attachment
with the sleeper position. All control functions are effected by the operator from the cabin of the two-way excavator.

- Uniform tamping quality and higher tamping performance as compared to manual labour
- Quick and simple exchange of the tamping unit with other attachment
- Track independent tamping of crane ways
