  • Publication number: 20040234337
    Abstract: The invention relates to a stamping device for compacting soil. Said device comprises an upper body and a lower body which can be linearly moved counter to each other by means of a drive, a guiding element and an integrated spring system. Said device can be manually guided by means of a handle over a working area. In order to transfer as little oscillation as possible to the handle, said handle is connected to the upper body and the lower body by means of an intermediate element extending between the upper body and the lower body, in which area the movement or weight forces from the upper body and the lower body are extensively compensated.
