Abstract
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.
Claims17
A hand-held tamping machine for compacting track ballast below a track sleeper, the tamping machine comprising:
- a tamping pick for penetrating the track ballast;
- a vibration generator for vibration excitation of said tamping pick, said vibration generator being configured such that forces generated for said vibration excitation of said tamping pick act perpendicular to a shaft axis;
- a motor connected with said vibration generator via a drive shaft, said drive shaft having said shaft axis;
- a handle assembly with at least one handle for steering the hand-held tamping machine during operation;
- said at least one handle being arranged, along said shaft axis of said drive shaft, above at least one of:
- a machine center of gravity of the hand-held tamping machine by at least 30% of an overall height of the hand-held tamping machine;
- or
- a motor center of gravity of said motor by at least 15% of the overall height of the hand-held tamping machine.
