Abstract
A working device for ground compaction comprises an upper mass, a guide device coupled to the upper mass and intended to guide the working device, a lower mass which can move relative to the upper mass, which is movably coupled to the upper mass via a spring device, and which has a ground contact plate, and a vibration-generating device for producing a relative movement between the upper mass and the lower mass. Furthermore, a drive for driving the vibrating-generating device is provided, wherein the drive comprises an electric motor. The electric motor is supplied with electrical energy via an electrical energy store arranged on the guide device.
Claims16
An implement for compacting the ground comprising:
- an upper mass;
- a guide apparatus, coupled to the upper mass, for guiding the implement;
- a lower mass which can move relative to the upper mass, which is coupled to the upper mass via a spring device so as to be able to move, and which has a ground contact plate;

- and
- a drive for driving the oscillation excitation apparatus;
- wherein
- the drive has an electric motor;
- and
- the electric motor can be supplied with electric power by an electrical energy store arranged on the guide apparatus.
