Embodiment Construction

[0042]FIG. 1 schematically shows, in a lateral sectional view, a tamper 1 having an upper mass 2 and a lower mass 3 that can be moved relative to upper mass 2. Lower mass 3 has a tamper foot having a ground contact plate 4 that acts as a ground contact device. Upper mass 2 includes, inter alia, a drive device (not shown) having an electric motor (not shown) that drives a crank drive (not shown) connected to lower mass 3. Through the crank drive, upper mass 2 and lower mass3 can be set into an oscillating movement relative to one another, through which ground contact plate 4 is forced into a tamping working movement. Through the tamping, a region of the ground 5 situated underneath tamper 1 and ground contact plate 4 in the depicted upright working position can be compacted in a tamping manner.

[0043]For the guidance of tamper 1 by an operator, a guide bracket 6 is provided on which for example an operator handle can be situated. Guide bracket 6 is situated on upper mass 2. It can be ...

Abstract

A piece of equipment which has a ground contact device for working on a ground region located below the ground contact device in the working position of the piece of equipment, a driving device which can be operated by an electric motor in order to produce a working movement of the ground contact device, an electrical energy accumulator, enclosed by a housing, for supplying the electric motor with electrical energy, and a covering device for covering the housing and thus the energy accumulator, which covering device is arranged above the energy accumulator in the working position. The piece of equipment may for example be a tamper, a vibration plate, a roller, or a breaker.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a working device for processing a region of the ground, for example a tamper, a vibrating plate, a roller, or a breaker.[0003]2. Discussion of the Related Art[0004]Working devices for processing the ground are increasingly offered having electric motors, the electric motors being capable of being supplied with electrical energy by accumulators also carried on the working device. Due to the high power requirement, the accumulators have a large performance capacity, and are therefore valuable and expensive components. In order to achieve a good degree of acceptance of such working devices, it is therefore necessary to ensure a long working life and operating time of the accumulators.SUMMARY OF THE INVENTION[0005]The present invention is based on the object of indicating a working device for ground processing, supplied with power by an electrical energy storage device that promotes a long w...
