Curb broom device and system

A sweeping system comprising:

• a curb brush device for attachment to a vehicle having a forward direction of movement, the curb brush device comprising:
• a frame configured for attachment to the vehicle such that the frame extends forwardly from the vehicle, the frame including:
• a frame attachment bracket;
• and
• a rail pivotally coupled to the frame attachment bracket such that the rail pivots with respect to the frame attachment bracket about a substantially vertical axis when the curb brush device is attached to the vehicle for use;
• a brush arm coupled to the rail, the rail and brush arm extending transversely with respect to the forward direction of movement of the vehicle when the curb brush device is attached to the vehicle for use, the brush arm being movable along the rail in a direction lateral to the forward direction of movement;
• a brush assembly mounted on the brush arm to move with the brush arm in the lateral direction to a position laterally offset from the vehicle when the curb brush device is attached to the vehicle for use, the brush assembly including a brush rotatable about a rotation axis with respect to the brush arm;
• and
• a roll axis orientation adjustment assembly configured to adjust a roll orientation of the brush assembly about a roll axis with respect to the brush arm, the roll axis being oriented substantially perpendicular to the rotation axis of the brush.
