Beschreibung
Zusammenfassung:	A cleaning device for heat exchangers having tube bundles includes a lance with nozzles to be introduced through an opening in a heat exchanger into a tube bundle in the heat exchanger. A hollow cylinder guides the lance. A flange connected to the hollow cylinder fastens the hollow cylinder at the opening of the heat exchanger. The lance is incrementally advanced. A pivot device for moving the lance includes a motor disposed on the hollow cylinder, a pendulum gear connected to the motor, and a carrier engaging the pendulum gear. The carrier has wheels guided in longitudinal grooves formed in the lance.
