Abstract
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.

A hand-held tamper for tamping ballast of a track, the tamper comprising:
- a drive motor for rotation of an imbalance;
- a shaft connected to said drive motor, said shaft having a lower end and a longitudinal axis;
- a tamping blade fastened to said lower end of said shaft;
- said tamping blade having two blade halves each connected to said shaft;
- each of said blade halves having an upper blade part and a lower blade part, with said upper blade part being positioned closer to said drive motor than said lower blade part and said upper and lower blade parts enclosing an angle α<180° with regard to one another;
- and
- said blade halves enclosing an angle β<180° with regard to one another, when viewed in a direction of the longitudinal axis of said shaft.
