 The The invention relates to a device for cleaning sink boxes according to The preamble of claim 1. So-called sink boxes are located mainly on roadsides, um effluent surface water take. They are common too under the name street gully known.

It this is box-shaped shafts, in which is usually inserted a sieve insert. In this sieve insert will all Rubbish, with the surface water flushed is, sieved. The sifted water can then either infiltrate or into a related to the gully road drains be derived.

The gullies are usually provided with lids for safety reasons. These lids are for the drain of the Surface water openings, mostly slots, have, are made for the most part of cast iron. They therefore have a comparatively large weight, that is, a weight greater than 30 kilos, up. As with the surface water a lot of coarse dirt gets into the sieve inserts of the sink boxes, have to cleaned these regularly become. This is done according to the prior art in various ways accomplished.

A Method is to use a vehicle that has a loading bed or Mud well and u. U. over has a lifting crane, close to the Sink box to drive. The sink box is manually or by means of lifted and placed next to the gully. Subsequently, the Sieve insert of the sink box hanged up and above the platform or sludge trough the vehicle is emptied. The reset the Siebeinsatzes and closing the sink box completes in reverse order.

The described procedure is extremely time-, force- and laborious. Even if a crane is present, must for the operation be provided a separate force of the lifting crane. This must the lifting crane snugly Taxes. In particular, for inserting the sieve insert and the Manhole cover is for this according to time needed.

A very common Type of gully cleaning is by means of a street sweeper carried out, the above a suction tube features. Here you have to but two additional to the driver of the street sweeper Managers to be manually raised lift the sink box lid. Subsequently the suction tube is inserted into the sieve insert and the therein Sucked dirt. Following this The sink box lid is again manually in its lid seat inserted. This method is at least as labor intensive as the one described above, in particular, the high weight of the sink box lid in the manual lifting is.

With the DE 42 23 931 A1 a sewer cleaning vehicle has become known in which a manhole cover can be lifted out of its seat with a magnetic lifter and deposited laterally from the manhole after a pivoting movement. A suction hose held separately from a carrier guided forwardly over the vehicle is then discharged into the shaft to be cleaned. However, this is a sewer cleaning vehicle and not a device for cleaning sink boxes.

With the DE 43 28 480 C1 Furthermore, a vehicle for cleaning and emptying of gullies has become known in which a sink box lid is lifted by means of a gripper system and linearly offset. Then a suction hose is inserted into the sink box lid for cleaning. The release of the Sinkkastenöffnung using the Linearvorschubs represents a relatively complex design. In addition, this document gives no information about the positioning of the suction hose above the sinker.
