Abstract

L'invention concerne un dispositif à pieds d'appui pour semi-remorque ou équivalent, comprenant au moins un pied d'appui (1,1'), de préférence télescopique. Le pied d'appui (1, 1') a une tête de fixation (11) par laquelle il est fixé au semi-remorque, et un dispositif de compensation de charge (2) qui est disposé sur le pied d'appui (1, 1') et autorise les mouvements de compensation latéraux générés sur le pied d'appui en cas de différences de charges. En guise de dispositif de compensation de charge (2), la tête de fixation (11) du pied d'appui (1, 1') est montée rotative autour d'un axe de rotation (21) sensiblement horizontal et perpendiculairement à la direction longitudinale du semi-remorque. L'invention concerne également un procédé associé pour l'équilibrage de charge.
