There is described a carriage for a sewer cleaning device, the diameter of said carriage being adjustable such that it can be adapted to the diameter of a sewer. The carriage has running rollers (14) which are articulated on the ends of first and second scissors arms (12, 13). The inner ends of the scissors arms (12, 13) are located at the first and second sleeves (6, 7). The second sleeve (7) is arranged in a rotatable manner on a central carrier (1), while the first sleeve (6) is screwed onto a tube extension (4). By rotation of the first sleeve (6), the first sleeve (6) is displaced on the tube extension (4), as a result of which the scissors are closed or opened and the diameter of the carriage is accordingly adjusted. |
