Montech is a commune in the Tarn-et-Garonne department in the Occitanie region in southern France. |
| Description | Wikipedia: The slope has been out of service since an engine failure in 2009. Operating principles The principle of the water slope is based on a sloping channel up or down which a wedge of water retained by a water tight gate is moved. This technique was invented in the 19th century by the German engineer Julius Greve and described by the French engineer Jean Aubert in 1961. The Montech water slope was inaugurated in July 1974. A sloping concrete channel is continuously fed by a small stream of water, thus overcoming any leakage at the seals around a movable gate. The movable gate spans the channel. The points of contact of the gate with the channel are tight but not fixed. Two adapted diesel locomotives, one on either side of the channel support the gate. To allow a boat to ascend: the movable gate is lifted, the boat enters the channel, and then the gate is lowered. This isolates a wedge of water, on which the boat is floating, from the canal it has left. The locomotives ascend the slope pushing the water wedge in front of the movable gate. The boat rides on the water wedge. When the water level in the wedge matches that of the upper canal, an upper (non-moving) gate is opened and the boat is then allowed to float free. To descend the process is reversed. Details of the machinery By virtue of its power and ingenuity the slope's mobile barrier is the key to the system. It consists of: Two locomotives, rigidly connected together by a cross piece which spans the channel, with the locomotives travelling on the channel's banks. The gate, which acts as a big slide-valve, connected to the rigid cross member by an arm. A horizontal beam serving as a shock absorber between the boats and the gate. Each diesel electric locomotive develops 1,000 horsepower (750 kW) distributed to four drive motors, one on each of the four axles each with two large pneumatic tyres. The three contact faces of the gate with the channel are equipped with seals to keep the wedge of water in place. The gate is raised or lowered using a hydraulic ram. The shock absorber is a hydraulically levelled hinged metal frame. It allows boats to be connected to the gate during ascents and descents. An electronic system keeps motion gentle and smooth. Finally triple brakes slow the system without jerks. Design features Weight of the engines: 200 tonnes |
