Abstract:
A tamper for soil compacting, comprising a built-in drive (3) which executes approximately vertical vibrations of a tamper foot (2), a guide handle (6) for operatingly holding the tamper, said guide handle (6) having a bracket means (7) attached thereto and being rigidly mounted on a tamper axis (A) of said tamper and elastically pivoted about an axis perpendicular to said tamper axis (A) on at least one pivot point (8) and having a grip end (9), wherein a mass distribution of the guide handle brings about a reduction of vibrations at the grip end, the mass distribution and a geometry of the guide handle satisfy the following equation: ##EQU3## wherein: m.sub.S =mass of the guide handle (6);.THETA..sub.S =inertial moment of the guide handle (6) around an axis through a center of gravity (10) of the guide handle (6), which extends parallel to an axis leading through the pivot point (8);l.sub.H =distance perpendicular to the tamper axis (A) between the axis leading through the pivot point (8) and the center of gravity (10);l.sub.HG =distance perpendicular to the tamper axis (A) between the grip end (9) and the center of gravity (10); andl.sub.v =distance parallel to the tamper axis (A) between the axis leading through the pivot point (8) and the center of gravity (10).
