Teltow , a catenary boat on the Teltow Canal

A catenary boat or catenary ship is an electrically powered watercraft. Like a trolleybus , it draws its traction current from one to three contact wires of an overhead line by means of pantographs , whereby the ship can deviate a few meters from the ideal line to the side. A well-known example was the Teltow tug in the upper water of the Kleinmachnow lock on the Teltow Canal . The catenary ferry is a special form of the catenary boat .

history

Test drive of a catenary boat named after Frank W. Hawley on the Erie Canal

Frank W. Hawley converted a conventional canal steamship into an electrically powered catenary ship and tested it on the Erie Canal in 1893. It had two electric motors with 19 kilowatts (25 hp) each that drove two propellers.

From 1899, a catenary boat powered by a propeller operated on a four-kilometer section of the Charleroi-Brussels Canal , which was used as a tug to pull barges or barges . Another ship overhead line was installed in 1933 on a piece of the Rhine-Marne Canal and is still in operation today. A six-kilometer-long overhead contact line runs through the 3.3-kilometer-long canal tunnel of the Canal de Bourgogne in the canton of Pouilly-en-Auxois .

After the construction of the Teltow Canal , a trial operation with the Teltow tugboat with overhead line for electric towing operations took place on Lake Machnower from 1903 .

Electric chain shipping has been operated in the Riquevaltunnel in the French department of Aisne since 1906 . The chain ship uses a chain to move that is laid in the bottom of the canal and then runs across the deck of the ship. Here it is guided over rollers that are driven by an electric motor. In this way, the tug reaches a speed of around 2.8 km / h. The passage through the 5670 meter long tunnel takes about two hours. A three-pole overhead line for the power supply is attached to the ceiling of the tunnel, which continues for about 200 meters at both ends of the tunnel. The chain ships are supplied with the required electrical energy by two pantographs .
