A hand-held tamping machine for compacting track ballast has a tamping pick for penetrating the track ballast, a vibration generator for vibration excitation of the tamping pick, a motor connected with the vibration generator via a drive shaft, and a handle assembly with at least one handle for steering the hand-held tamping machine during operation. Along a shaft axis of the drive shaft the at least one handle is arranged above the machine center of gravity of the hand-held tamping machine by at least 30% of the overall height of the hand-held tamping machine and/or is arranged above the motor center of gravity of the motor by at least 15% of the overall height of the hand-held tamping machine.

A machine-tool system, particularly for work on a railway line, having at least one machine-tool such as an abrasive rail saw, and a device for driving the machine. The machine-tool is provided with an electric motor powered by an electric battery which is advantageously arranged in an assembly that can be worn by the operator of the machine and is connected to the motor by a power discharge cable.

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.

A hand tamper for tamping ballast of a track includes a drive motor for rotation of an imbalance or unbalanced weight and a barrel tip which is approximately V-shaped in longitudinal section and is fastened to a lower end of a barrel connected to the drive motor. A plurality of barrel fins extending in a longitudinal direction of the barrel are disposed on a lower barrel section adjoining the barrel tip. The barrel fins are spaced from one another relative to a barrel cross-section, extend radially from a barrel surface and are elongated into the barrel tip.

A tamper cart system for transporting a mechanical tamper includes a mechanical tamper. The mechanical tamper has a handle, a body and a compression plate. A cart is provided and the cart is rolled along a support surface. The mechanical tamper is selectively positioned on the cart. Thus, the mechanical tamper is transportable by an individual. A handle is movably coupled to the cart.

A hand-held tamper for underfilling ballast of a track. The tamper has a drive motor for the rotation of an unbalance and a tamping shovel fastened to a lower end of a shaft which is joined to the drive motor and has a longitudinal axis. The shovel consists of two shovel halves each joined to the shaft. Each shovel half has an upper shovel part nearer to the drive motor and a lower shovel part positioned at a first angle <180 in relation thereto. Both shovel halves are disposed at a second angle <180 relative to one another when viewed in the direction of the longitudinal axis of the shaft.
