ABSTRACT:
A compact and stable vibratory tamper of relatively low height comprises a crank case, a laterally mounted motor which is arranged to impart a linear reciprocating motion to an intermediate member via a planetary gear arrangement, a crankshaft, and a crank arm, and a tamping foot which is moved by the intermediate member by means of at least two oppositely acting springs which act between the intermediate member and the tamping foot and which overlap at least partially in the axial direction.
