A support system ( 1 ) for the suspension of a roller broom ( 2 ) on a sweeping vehicle comprises a rotary support ( 3 ) mounted to turn on the sweeping vehicle around a vertical slewing axis ( 7 ), a support part ( 5 ) suspended on the rotary support via a lifting mechanism ( 4 ) comprising a lifting drive ( 26 ), and a broom frame ( 6 ) mounted on the support part to rock around a horizontal axis ( 16 ) extending perpendicular to the axis of rotation (L) of the roller broom. For this purpose there is provided, in the region of the pendulum bearing ( 14 ) of the broom frame, a movably mounted locking member ( 17 ), which can occupy a first position that enables the rocking movement of the broom frame and a second position that disables the rocking movement of the broom frame in its leveled condition, and on which the lifting drive of the lifting mechanism acts in such a way that the locking member occupies its second position when the lifting drive is activated. |
