CA 2290465

The invention concerns an impact compactor (10) which comprises one or more out-of-round compactor masses (14). The masses are moved rotationally over a soil surface, at an angular velocity suitable for normal operation, to apply periodic compaction blows to the soil surface. This is achieved by primary drive means. In the case of a towed impact compactor, the primary drive means is typically a tractor. The impact compactor (10) includes an auxiliary drive which is arranged to operate automatically, in response to a reduction of the angular velocity of the compactor masses below the angular velocity suitable for normal operation, to apply an auxiliary rotary drive that restores their angular velocity.

L'invention se rapporte à un dispositif de compactage produisant des percussions (10) et comportant une ou plusieurs masses de compactage disposées en faux-rond. Ces masses se déplacent de manière rotatoire à la surface d'un sol, et à une vitesse angulaire convenant à un fonctionnement normal, dans le but d'appliquer des percussions périodiques à la surface du sol et ce, grâce à un élément de commande principal. Lorsque l'invention concerne un dispositif de compactage produisant des percussions remorqué, l'élément de commande principal est généralement un tracteur. Ledit dispositif (10) comporte une unité de commande auxiliaire qui est conçue pour fonctionner automatiquement en réponse à une réduction de la vitesse angulaire des masses de compactage à une vitesse inférieure à la vitesse angulaire convenant à un fonctionnement normal, le rôle d'une unité de commande rotatoire auxiliaire étant de rétablir la vitesse angulaire desdites masses.
