Earliest inclined plane?

edit

I would be very interested to see some dates on this page? I have been working on a page for John Edyvean who used inclined planes in 1770's are these the earliest in the the UK?

A tricky one because we run into the problem of defintions. The mostly likely case for a pre 1770 inclined plane I can think of is the internal inclined planes inside the Duke of Bridgewater's coal mines. I don't know the exact date those appeared though.Geni 16:28, 26 February 2006 (UTC)Reply

The text stated that boats are perpendicular to the inclined plane, but shows an example where its clearly in line. I have amended the text to says "sometime perpendicular"

Appears to be suffering from a lack of coverage of developmeants outside the UK.Geni 23:08, 19 April 2007 (UTC)Reply

I'll see what I can find. Martin Cordon 21:12, 20 April 2007 (UTC)Reply

Caisson link?

edit

Caisson is a DAB page, but caisson (engineering) relates to structures which are effectively the inverse of what's used here (ie a box filled with air and submersed, upside-down, in the water). Something doesn't seem right - maybe there's another sense of caisson that's not yet defined in WP?

The word Caisson is the word most commonly used in relevent literature to describe the water filled trough on canal inclines and lifts. Unfortunately, this bears no resemblance to any of the caisson's described in the caisson (engineering) link. An extra paragraph describing the type used on canals may be appropriate.

Good stuff - that's what was needed. (It needed a slight tweak to read right, which I've done.) Thanks. EdJogg 18:25, 9 June 2007 (UTC)Reply

Grammar

edit

I'm not sure what this sentence means. "On some canals an inclined plane was used just to the transfer the loads up or down to the boats on a rail system." I was going to fix the grammar, but could not be sure exactly what the writer meant. Anyone care to clarify? (I was looking at the article as there were three planes on the Kidwelly and Llanelly Canal), but I have not found any details of how they worked, yet. Bob1960evens 19:51, 22 October 2007 (UTC)Reply

I scanned through the history to see if I could identify the original context of the edit. Unfortunately, it was added exactly as typed here. However, I have traced the editor Talskiddy (talk · contribs), who added it in June 2006. I have added a comment on his talk page asking for him to take another look at it.

St. Columb Canal was built using inclined planes but also had an inclined plane that linked the canal to the beach at Newquay. This was for the purpose of lifting up loads. Please feel free to edit it if it doesn't make sense.Talskiddy (talk · contribs), 10:25, 23 October 2007 (UTC)Reply
Thanks for pointing us in the right direction. This link (which I found on the St. Columb Canal page) includes a picture which clearly shows the inclined plane from the beach. As it was a tub-boat canal, I'm not sure that this inclined plane is particularly different from any other. I would have expected that the tub-boats would be lowered to beach level for loading, and then raised to the canal using the plane. Hence I'm not convinced that the sentence is needed.

Lede section

An inclined plane is quicker and wastes less water than a flight of canal locks, but is more costly to install and operate. A development of the idea is the water slope. An alternative to consecutive locks is a boat lift.

Operation

edit

Typically, such a feature consists of a slope, with one or more rail tracks on it. Boats are raised between different levels by sailing into water-filled tanks, or caissons, with wheels on the bottom and watertight doors at each end. The caisson is mounted on an angled wheelbase, to keep it horizontal to the water level, and is generally aligned sideways to the slope. These are drawn up or down hill on the rails, usually by means of cables pulled by a stationary engine. In most designs two caissons are used, one going up and one down, acting as counterweights for greater efficiency. When the caisson has reached the top or bottom of the slope, the doors open and the boat leaves.[citation needed]

There are also inclined planes without a tank or caisson, instead carrying vessels up out of the water cradled in slings or resting on their keels. In a few cases the boats were permanently fitted with wheels.[citation needed]
