TAMPING DEVICE FOR COMPACTING SOIL, CONCRETE, AND THE LIKE

摘要

A tamping device which has a tamping foot and a mass above the foot in the form of a drive motor or engine and a crank driven thereby with a rod connected to the crank for being reciprocated thereby in the vertical direction and having a resilient connection with the tamping foot. The mass is also resiliently supported on the tamping foot and relative movement between the mass and the tamping foot is confined to a single vertical plane and within which plane the mass and tamping foot are moveable relatively in the vertical direction while the mass can be moved a certain amount laterally relative to the tamping foot in the plane or can be tilted in the plane whereby steering and movement of the device while in operation can readily be controlled by forces exerted manually on the mass.
