Abstract
A tamping unit for tamping a track has tamping tools arranged in pairs. The tamping tools can be squeezed towards each other by a respective squeezing cylinder. A squeezing piston can be subjected to a hydraulic pressure of a first hydraulic circuit arranged in the respective squeezing cylinder. A vibration piston is assigned to each squeezing cylinder to superimpose a vibration on a squeezing movement. The vibration piston is arranged in a pressure amplifier with a primary cylinder and a secondary cylinder. In this way, vibration generation can be carried out at a lower pressure level.
