France's waterway network of nearly 5,000 miles is based primarily on its rivers, but many of the low-capacity canals are being raised to the 1,350-ton standard. A major development planned in the 1970s in cooperation with West Germany was the construction to this standard of the North Sea-Mediterranean waterway via the canalized Rhône and Rhine rivers. With four existing locks built for the Grand Canal d'Alsace, a projected lateral canal between Huningue and Strasbourg, the project was modified in 1956, and the four remaining dams were to be built on the Rhine itself and bypassed with short canals including four locks, three with two chambers each. Canalization of the Rhône started with the building of the Port of Edouard-Herriot downstream from Lyon, and work proceeded on 12 locks and dams. Two new ports, serving Valence and Montélimar, were being constructed. Improvements were also made on the Marne-Rhine waterway, which provides an important internal trade route connecting the Paris Basin with the industrial regions of Alsace-Lorraine. The improvements included major works on either side of the Vosges summit level, replacing 23 old locks. At Réchicourt a new lock with a lift of 32 1/2 feet bypasses six locks and a winding section of the old canal; on the other side of the summit a new canal section bypasses 17 locks, which formerly required 8 to 12 hours to navigate. On this section the inclined plane of Saint-Louis-Arzviller deals with a difference in level of 146 feet with a horizontal length of 422 feet. Two tanks each carry a 350-ton barge. Their 32 wheels run on four rails, and two sets of 14 cables connect the tanks to the two concrete counterweights. Improvements have been made to routes connecting the Seine with the north and east. The Canal du Nord was completed in 1965, and a bottleneck was removed on the Oise Lateral Canal with the building of two locks to accommodate through convoys to Paris.

If the pulled it up, it would crumble to pieces. It is too big and too deep. The Titanic had a gross weight of 46,000 tons, or 92 million pounds. There are no cranes or winches capable of handling those kinds of weights. The ship is very deep, too deep for divers to work. It is below the water, which means you have to build 'land' above the ship to put the cranes and winches on. And the water moves with waves, wind and storms. +++ You are probably right about Titanic being too big to lift but sunken vessels are sometimes lifted by a combination of buoyancy tanks and crane-barges. You do not need land, just a sufficiently large crane-barge and floating-dock! Besides, why do you want to raise her? Leave her in peace, as a grave.
What type of pressure. Steam engines operate on high-pressure water vapor, that is steam, the higher the pressure- in lay terms, the more work one can get out of the steam- hence greater power, she had two multiple expansion reciprocating engines of outsize nature- naturally, and one turbine running on exhaust steam and only in forward gear- overdrive of sorts. This does not count engines used on cranes, steam winches, the power-steering gear, and numerous other auxiliaries- there was a separate engine plant for what were called ( electricity engines) steam generators to supply electric power for all domestic appliances ( including elevators, hoists, etc and of course lighting. The pressures involved would vary, Marine engineers being conservative blokes, but anything from l50-maybe 300 Pounds per square inch might be used, more during speed trials, a good question.
One could purchase Warn winches from Canadian Tire, the physical stores and online. The Warn Winches are weather resistant and reliable electric/hydraulic winches used in industries.
There are many places that provide satisfactory electric winches. One of the most reliable places with the widest spread array of electric winches is Amazon.
The hydraulic winches are usually powered by a motor. They can also operate under water.
If you are looking for old winches, there are a lot of 4WD vehicles in the junk yard, you can probably find some winches attached to those vehicles, check in your local area.
The power takeoff on a Ford tractor is designed to operate equipment like plows, winches, and mowers. It uses the power of the engine to readily run accessories.
The question should be what is the difference between a winch and a hoist. In this case they are both powered by compressed air. Both winches and hoists are available which can be powered by air, electricity, hydraulics, or manual power (other means of powering this equipment is also available). A hoist is made for lifting. A winch is made for dragging/pulling. A hoist is designed with a special safety factor, limit switches and redundant braking for overhead lifting. Winches are designed to a completely different criteria. Keep in mind that several companies have manufactured "hybrid" winches which are made to lift. They are basically dual purpose pieces of equipment (hoist/winch).
ATV winches can be found on a variety of different sites online, such as amazon or ebay. You can also most likely pick them up from your local Sears.
Electric winches can be expensive and cheap. Depending on the size, model, and where you get it from. I suggest browsing your local DYI stores and try to find the best price.
With steam. It powered winches and cables.
The plural form for the noun winch is winches.
The winches make use of the gear train in its operation.
