Abstract

Des moyens augmentent l'efficacité lors du déplacement de charges selon le principe d'étape de glissement décrit dans le brevet européen N° 0 155 235, par exemple en passant pendant la phase de déplacement d'un frottement statique à un frottement roulant. La Fig. 2 montre un dispositif similaire à celui de la Fig. 1, dans lequel deux forces supplémentaires (22 et 23) s'exercent au moyen de rouleaux (24, 25) sur la charge (20), outre la force (21) qui s'exerce obliquement sur la charge. L'action simultanée des forces (21, 22, 23) réduit pendant l'avancement le frottement de la charge sur le fond sous-jacent, ce qui déplace la diagonale de guidage de la charge dans la direction (26) et réduit la résistance due au frottement sur le sol, par rapport à l'étape de glissement selon la Fig. 1, à une fraction de celle-ci.
