Vibratory tamping machine for compacting a ballast bed of a track

Abstract

A vibratory tamping machine for compacting a ballast bed of a track has a vibration mechanism which is driven by means of an electric drive motor. The vibratory tamping machine has a vibration decoupling device, which defines a decoupling plane and separates a working side from an operating side, for the vibration-decoupling of at least one handle. The handles are arranged on the operating side, whereas the electric drive motor and the vibration mechanism are arranged on the working side.
