Claims20
An impact wrench for tightening and loosening nuts and screws on a track for connecting rails to associated sleepers, the impact wrench comprising:
- an impact screwing mechanism comprising an impact screwing mechanism axis of rotation;
- an electric drive motor for driving the impact screwing mechanism, the electric drive motor comprising an electric drive motor axis of rotation, the electric drive motor axis of rotation being identical to the impact screwing mechanism axis of rotation;
- a rechargeable battery for supplying the electric drive motor with electrical energy;
- at least one handle for holding the impact wrench, the impact wrench comprising a vibration decoupling device for vibration decoupling of the at least one handle and of the impact screwing mechanism;
- a housing;
- and
- a support frame, wherein the electric drive motor and the impact screwing mechanism are arranged in the housing and the at least one handle and the rechargeable battery are arranged on the support frame, wherein the housing and the support frame are exclusively connected to each other via fixing elements and a plurality of vibration dampers.

An impact wrench, comprising:
- an impact screwing mechanism comprising an impact screwing mechanism axis of rotation;
- an electric drive motor comprising an electric drive motor axis of rotation, the electric drive motor axis of rotation being identical to the impact screwing mechanism axis of rotation, the impact screwing mechanism being configured to be actuated via the electric drive motor such that a screwing head connected to the impact screwing mechanism is rotated for tightening and loosening nuts and screws on a track for connecting rails to associated sleepers;
- a rechargeable battery for supplying the electric drive motor with electrical energy;
- at least one handle for holding the impact wrench;
- a vibration decoupling device for vibration decoupling of the at least one handle and of the impact screwing mechanism;
- a housing;
- and
- a support frame, wherein the electric drive motor and the impact screwing mechanism are arranged in the housing and the at least one handle and the rechargeable battery are arranged on the support frame, wherein the housing and the support frame are exclusively connected to each other via fixing elements and a plurality of vibration dampers.
